Accurate prediction of hydrogeological parameters and groundwater potential is essential for sustainable groundwater management, particularly in regions experiencing irregular rainfall, increasing water demand, and declining groundwater levels. This research paper presents a machine learning-based framework for predicting hydrogeological parameters and developing a Groundwater Potential Index (GWPI) by integrating geospatial datasets with borehole records. The proposed approach combines terrain characteristics, geological formations, soil properties, land use and land cover, drainage density, rainfall, slope, and remotely sensed indices with borehole-derived information, including water-table depth, aquifer thickness, lithology, and well yield. Machine learning algorithms such as Random Forest, Support Vector Regression, Gradient Boosting, and Artificial Neural Networks can be employed to estimate hydrogeological variables and identify areas with different groundwater potential levels. The predicted parameters are integrated within a geospatial framework to generate a spatially distributed groundwater potential index. Model performance can be assessed using the coefficient of determination (\\(R^2\\)), root mean square error (RMSE), and mean absolute error (MAE). The proposed framework offers a reproducible and scalable approach for groundwater exploration, borehole siting, and regional water-resource planning. Since no study-area dataset or model outputs have been provided, the paper presents a methodological framework rather than claiming experimentally validated results.

The study area comprises agricultural fields within the North Caucasus Federal Agricultural Research Center in the northeastern spurs of the Stavropol Upland. Landsat 5\u002F8 imagery and spectral indices (NDVI, NBR2, and BSI) were used to classify BSS. Optimal discrimination of BSS from green and non-photosynthetic vegetation was achieved, using a BSI threshold of >0.18 (F1-score = 0.98). Spatial modeling of topsoil properties was conducted by comparing five regression models (Linear Regression, K-Nearest Neighbors, Random Forest, Extreme Gradient Boosting, and Cubist). A linear regression model demonstrated the highest performance; key predictors included the mean and standard deviation of SWIR2. The model exhibits strong predictive capability for sand, silt, clay, and total carbon (adjusted R 2 = 0.82, 0.75, 0.78, and 0.74, respectively). The topsoil is characterized by the range of clay content from 5 to 30%, of silt content from 15 to 60%, of sand content from 20 to 80%, and of total carbon from 0.5 to 3%. Predictive maps of texture and total carbon derived from BSS reveal considerable local heterogeneity, with soils consisting of Chernozems and Phaeozems, influenced by parent rock variability. The modeling results highlight the high predictive power of the BSS spectral characteristics, even when used as a single predictor for digital soil mapping.","本研究探讨了利用遥感数据检测裸露土壤表面（BSS）的可能性，并将该方法应用于表层土壤质地和总碳的建模。研究区包括位于斯塔夫罗波尔高地东北支脉的北高加索联邦农业研究中心内的农田。利用Landsat 5\u002F8影像和光谱指数（NDVI、NBR2和BSI）对BSS进行分类。当BSI阈值>0.18时，实现了BSS与绿色植被及非光合植被的最优区分（F1分数=0.98）。通过比较五种回归模型（线性回归、K近邻、随机森林、极端梯度提升和Cubist）对表层土壤属性进行了空间建模。线性回归模型表现出最高的性能；关键预测变量包括SWIR2的均值和标准差。该模型对砂粒、粉粒、黏粒和总碳表现出较强的预测能力（调整R²分别为0.82、0.75、0.78和0.74）。表层土壤的黏粒含量范围为5%至30%，粉粒含量为15%至60%，砂粒含量为20%至80%，总碳含量为0.5%至3%。基于BSS生成的质地和总碳预测图揭示了显著的局部异质性，土壤由黑钙土和暗色始成土组成，受母岩变异性的影响。建模结果凸显了BSS光谱特征的高预测能力，即使仅作为数字土壤制图的单一预测变量使用亦然。","Eurasian Soil Science","2026-10-15T00:00:00Z",10,69,{"impact":19,"substance":120,"depth":121,"authority":122,"freshness":18,"relevant":23,"comment":123},20,16,13,"方法新颖、结论可靠，但属区域尺度研究，公共影响有限，适合作为技术类精选。",[125],{"name":115,"url":112},[30,31,127,128,129],"土壤碳","Landsat","数字土壤制图",{"code":62,"slug":67,"name":131,"path":132,"parent_code":133},"土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil","H",[135,136],{"code":35,"slug":36,"name":37,"path":38,"parent_code":39},{"code":55,"slug":137,"name":138,"path":139,"parent_code":39},"remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing",{"status":42,"locked":15,"version":43,"method":44,"evidence":141},{"candidates":142,"agricultural_evidence":49},[143,147,151],{"code":62,"score":20,"supported":49,"title":144,"abstract":145,"tags":146},[67],[66,67],[],{"code":35,"score":22,"supported":49,"title":148,"abstract":149,"tags":150},[51],[],[30],{"code":55,"score":18,"supported":49,"title":152,"abstract":153,"tags":154},[],[31,59],[128,31],[156,157],"Landsat 裸土 土壤碳","北高加索 土壤质地 遥感","Landsat裸土土壤碳-5178","10.1134\u002Fs1064229326601228",{"doi":159,"openalex_id":161,"authors":162,"venue":115,"cited_by_count":92,"oa_url":9,"card":195,"direction":103,"ingested_from":105},"W7222107492",[163,166,169,172,175,178,181,184,186,189,192],{"name":164,"orcid":165},"P.

Based on historical research, it is known that an improvement on resilient economic indicators such as ground water is often correlated with socio‐economic improvements and other aspects of rural livelihoods. The extent of factors affecting livelihood sustenance and improvement in the village of Raleras, Maharashtra, aids in creating a definite understanding of the facets correlating with groundwater restoration. Subsistence channels, arising as an outcome of the created impoundment structures, are tested for their impact on income gains and livelihood improvement. Examination on collected opinion was carried out to provide insights into the ‘before’ and ‘after’ (2015–2023) conditions. A five‐capitals framework has been employed for the interpretation of these results, along with a multivariate analysis to predict a causal framework for the improvement of livelihoods in agrarian economies through creation of check dams and watershed management. Time series study shows that there is greater variance in the NDVI progressively from 2021 to 2023 with values ranging from 0.25 to 0.50 in 2015, to 0.50–0.75 by 2021. Further increase in green patches in 2023 indicates enhanced vegetation health especially in the northern regions. Alternately, NDWI values elaborate initial severe water stress (−0.25 to 0.00) with progressive improvements in localized areas. The spatial variation map shows that eventually there is a notable improvement with more land supporting shrubbery along with more water bodies. The prominent increase in vegetation particularly in the later years can be attributed to water management initiatives undertaken in Raleras. The distributions of the annual average revenue from agricultural operations in 2015 (M = 146,907, SD = 95445.8) and 2023 (M = 706860.5, SD = 655748.3) showed a statistically significant improvement [ t (214) = 13.06, p \u003C 0.001]. The low p ‐value of 0.001205 ( p \u003C 0.05) of the educational facilities utilised indicates a statistically significant result, proving the association between educational quality and improved water facilities. All of the variables under evaluation, including the respondents' vehicle type, landholding type, and house type, have large and positive chi‐squared values, suggesting that the ‘before’ and ‘after’ distributions for each of these variables differ. Principal Component Analysis is used to summarise correlated livelihood indicators and reveals that income growth and livelihood improvement is multi‐dimensional. Multiple pathways to income change are identified through Partial Least Squares Regression, including agriculture and market‐linked channels. A Random Forest Regression Model is utilised to assess the relative importance of livelihood channels and baseline characteristics. Results indicate that improvement in irrigation access, crop diversification, housing quality, livestock ownership and female literacy are strongly associated with higher income gains. Hence, it may be said that the groundwater recharge as a result of construction of check dams must have improved agricultural activity or agricultural output in a material manner, and accordingly all capitals for Raleras have improved.","从社会经济视角来看，探究可持续水资源能否真正维持农村生计具有重要意义。基于历史研究可知，地下水等韧性经济指标的改善往往与社会经济进步及农村生计的其他方面相关联。马哈拉施特拉邦拉莱拉斯村影响生计维持与改善的因素程度，有助于明确理解与地下水恢复相关的各个维度。作为所建蓄水设施产物的生计渠道，其对面收入增长和生计改善的影响得到了检验。对收集到的意见进行了考察，以深入了解“之前”和“之后”（2015—2023年）的状况。研究采用了五资本框架来解读这些结果，并结合多变量分析，预测通过修建拦水坝和流域管理来改善农业经济生计的因果框架。时间序列研究表明，从2021年到2023年，NDVI的变异性逐渐增大，2015年数值范围为0.25至0.50，到2021年升至0.50至0.75。2023年绿色斑块进一步增加，表明植被健康状况改善，尤其是在北部地区。另一方面，NDWI值显示初期存在严重的水分胁迫（−0.25至0.00），后在局部地区逐步改善。空间变异图显示，最终出现了显著改善，更多土地能够支持灌木生长，同时水体也有所增加。植被的显著增加，尤其是在后期，可归因于拉莱拉斯村所实施的水资源管理举措。2015年（M = 146,907，SD = 95445.8）和2023年（M = 706860.5，SD = 655748.3）农业经营年均收入的分布显示出统计学上显著的改善[t(214) = 13.06，p \u003C 0.001]。所利用教育设施的p值为0.001205（p \u003C 0.05），表明结果具有统计学显著性，证明了教育质量与改善的供水设施之间的关联。所有受评估变量，包括受访者的车辆类型、土地持有类型和房屋类型，均具有较大且正向的卡方值，表明这些变量各自的“之前”和“之后”分布存在差异。","Natural Resources Forum","2026-10-07T00:00:00Z",73,{"impact":19,"substance":211,"depth":212,"authority":122,"freshness":18,"relevant":23,"comment":213},22,18,"以机器学习与遥感数据量化印度半干旱村庄水资源可持续性对生计的影响，方法扎实、结论具体，但属境外案例研究，对国内三农信息化仅有方法借鉴价值。",[215],{"name":207,"url":204},[217,30,32,218,219],"乡村振兴","遥感监测","灌溉农业",{"code":35,"slug":36,"name":37,"path":38,"parent_code":39},[222],{"code":70,"slug":223,"name":224,"path":225,"parent_code":133},"irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",{"status":42,"locked":15,"version":43,"method":44,"evidence":227},{"candidates":228,"agricultural_evidence":49},[229,233,237,243,248],{"code":35,"score":22,"supported":49,"title":230,"abstract":231,"tags":232},[51],[],[30],{"code":70,"score":18,"supported":49,"title":234,"abstract":235,"tags":236},[],[73,223],[32,219],{"code":238,"score":77,"supported":49,"title":239,"abstract":240,"tags":242},"C",[],[241],"livestock",[],{"code":244,"score":23,"supported":15,"title":245,"abstract":246,"tags":247},"G",[],[],[217],{"code":55,"score":23,"supported":15,"title":249,"abstract":250,"tags":251},[],[],[218],[253,254],"Raleras 马哈拉施特拉 水资源","check dam 地下水 生计","Raleras马哈拉施特拉水资源-4527","10.1111\u002F1477-8947.70100",{"doi":256,"openalex_id":258,"authors":259,"venue":207,"cited_by_count":92,"oa_url":9,"card":269,"direction":275,"ingested_from":105},"W7220922038",[260,263,265,267],{"name":261,"orcid":262},"Papiya Deb","https:\u002F\u002Forcid.org\u002F0000-0002-6554-5111",{"name":264,"orcid":9},"Roopsha Deb",{"name":266,"orcid":9},"Udaysinh Bhosale",{"name":268,"orcid":9},"Vemula Sai Vikas",{"tldr":270,"method":271,"finding":272,"direction":273,"opportunity":274},"用机器学习评估印度半干旱村庄水资源可持续开发对农村生计的社会经济影响。","NDVI\u002FNDWI遥感、五资本框架、多元分析与卡方检验，2015–2023数据。","水管理举措显著提升植被覆盖与农业收入，教育设施改善与水资源改善显著相关。","数字乡村与农业信息化","可结合遥感时序与农户调查，量化水利工程对生计的因果效应并推广至其他半干旱区。","农业人工智能与决策模型","2026-10-09T23:30:50.079298Z",{"id":278,"title":279,"url":280,"summary":281,"summary_zh":282,"content":9,"source_name":283,"source_url":280,"published_at":284,"category":13,"cover_url":9,"hotness":117,"is_selected":15,"score":92,"score_detail":285,"sources":287,"tags":289,"primary_topic":292,"secondary_topics":293,"classification":294,"search_phrases":305,"slug":308,"view_count":92,"doi":309,"paper":310,"created_at":331},4317,"Machine-learning modelling of regional landslide susceptibility in eThekwini, South Africa","https:\u002F\u002Fdoi.org\u002F10.1038\u002Fs41598-026-73316-x","The occurrence of landslides, particularly within urban landscapes, has gained significant research interest because of their devastating impacts on infrastructure, resulting in casualties, displacement, and economic losses. This study aimed to examine the probability of landslide events and landslide-prone areas within the eThekwini Metropolitan Municipality in KwaZulu-Natal Province, South Africa. To achieve this, robust machine learning models, including Random Forest (RF) and Support Vector Machines (SVM), combined with geospatial tools and key landslide-triggering factors, were considered in the analysis and characterised based on susceptibility indexes ranging from very low to very high based on various carefully chosen thresholds. The results indicate that land use, elevation, NDVI, and lithology are important landslide-influencing factors. In contrast, land use parameters, such as cultivated land and built-up areas, were associated with high susceptibility zones. Furthermore, RF yielded slightly higher overall accuracy scores than SVM, with accuracy scores of 99.45% and 98.63%, respectively. The SVM susceptibility output was further analysed based on the spatial distribution of formal and informal housing types. The results confirmed that only a small percentage of each housing type fell within the high-susceptibility zones, calculated as 1.33% and 2.41% for formal and informal housing, respectively. Although SVM is one of the strongest models, RF shows higher accuracy in landslide susceptibility modelling. Furthermore, its slightly higher recall score compared to its precision score is deemed most applicable for identifying landslide-prone areas. The study suggested that human-engineered land-use activities, such as road and property development, contribute significantly to increased landslide susceptibility within the eThekwini area.","滑坡的发生，尤其是在城市景观中，因其对基础设施的破坏性影响，导致人员伤亡、流离失所和经济损失，已引起广泛的研究关注。本研究旨在考察南非夸祖鲁-纳塔尔省eThekwini大都市自治市范围内滑坡事件的发生概率及滑坡易发区域。为实现这一目标，本研究在分析中采用了稳健的机器学习模型，包括随机森林（Random Forest, RF）和支持向量机（Support Vector

delineation of agricultural land is fundamental to agricultural planning, food-security assessment, land-resource management, and monitoring of land-use transformation. However, the heterogeneous and fragmented character of agricultural landscapes in southeastern Nigeria presents substantial challenges for satellite-image classification. This study comparatively evaluated Random Forest (RF), Support Vector Machine (SVM), Artificial Neural Network (ANN), and Convolutional Neural Network (CNN) for agricultural land mapping in Anambra State, Nigeria. Remotely sensed imagery was classified into waterbody, dense forest, agricultural land, built-up area, and bare ground using the four algorithms. Model performance was evaluated using 210 validation samples and multiple confusion-matrix metrics, including sensitivity, precision, specificity, negative predictive value, overall accuracy, balanced accuracy, and Matthew’s correlation coefficient. Agricultural land estimates varied from 1,000.26 km² (21.78%) for SVM to 1,099.12 km² (23.93%) for ANN. SVM achieved the strongest overall performance, recording 88.5% sensitivity, 85.2% precision, 75.0% specificity, 83.3% overall accuracy, 81.7% balanced accuracy, and a Matthews correlation coefficient of 0.643. CNN produced the lowest overall accuracy of 74.3%. The findings demonstrate that increased model complexity does not necessarily translate into superior classification performance and establish SVM as an effective approach for regional agricultural land delineation under heterogeneous tropical landscape conditions.

This study developed an integrated remote sensing, GIS, and explainable machine-learning framework to map potential UCI locations in Oued Zenati, northeastern Algeria, using Landsat 9 imagery and geospatial environmental variables processed in Google Earth Engine. ArcGIS Desktop 10.8 was used for the final cartographic layout and map generation. Predictor variables included land surface temperature, albedo, elevation, slope, distance to roads, distance to rivers, and population density. Because field observations of UCIs were unavailable, proxy reference samples were generated from vegetation, moisture, and built-up indicators. Under the prevailing semi-arid conditions, NDWI values remained below − 0.06 across the study area, and all cool-zone reference samples were therefore derived from the vegetation criterion (NDVI ≥ 0.20). Four machine-learning algorithms (Random Forest, Gradient Tree Boosting, CART, and MaxEnt) were evaluated using a 70\u002F30 training-testing split and independent validation. Gradient Tree Boosting achieved the highest discrimination ability (ROC-AUC = 0.916), whereas Random Forest provided the best threshold-dependent performance, with an accuracy of 0.900, Kappa of 0.800, Precision of 0.929, and F1-score of 0.897. Susceptibility maps showed that cooling potential is concentrated in vegetated and agricultural areas, while built-up and bare surfaces exhibit low cooling potential. SHAP analysis identified elevation as the most influential predictor, followed by slope, albedo, and land surface temperature, whereas distance to roads, distance to rivers, and population density exerted comparatively weaker effects. The proposed framework provides a robust, interpretable, and transferable approach for Urban Cool Island susceptibility mapping, supporting climate adaptation, green infrastructure planning, and sustainable urban development in semi-arid cities.","摘要 在半干旱地中海城镇，城市热胁迫日益加剧，因此识别城市冷岛（Urban Cool Island, UCI）格局对于气候适应性城市规划至关重要。本研究开发了一个集成遥感、GIS和可解释机器学习的框架，利用Landsat 9影像和在Google Earth Engine中处理的地理空间环境变量，绘制了阿尔及利亚东北部Oued Zenati潜在UCI位置图。使用ArcGIS Desktop 10.8进行最终制图布局和地图生成。预测变量包括地表温度、反照率、高程、坡度、距道路距离、距河流距离和人口密度。由于缺乏UCI的实地观测数据，研究从植被、湿度和建成区指标生成了代理参考样本。在半干旱条件下，研究区NDWI值均低于−0.06，因此所有冷区参考样本均基于植被标准（NDVI ≥ 0.20）提取。采用70\u002F30的训练-测试划分和独立验证，评估了四种机器学习算法（随机森林、梯度树提升、CART和MaxEnt）。梯度树提升取得了最高的判别能力（ROC-AUC = 0.916），而随机森林在阈值依赖性能方面表现最佳，准确率为0.900，Kappa为0.800，精确率为0.929，F1分数为0.897。敏感性图显示，降温潜力集中在植被和农业区域，而建成区和裸地表面的降温潜力较低。SHAP分析表明，高程是最具影响力的预测变量，其次是坡度、反照率和地表温度，而距道路距离、距河流距离和人口密度的影响相对较弱。所提出的框架为城市冷岛敏感性制图提供了一种稳健、可解释且可迁移的方法，可支持半干旱城市的气候适应、绿色基础设施规划和可持续城市发展。","2026-10-03T00:00:00Z",66,{"impact":18,"substance":120,"depth":121,"authority":122,"freshness":22,"relevant":23,"comment":460},"方法新颖、结论可靠的城市冷岛遥感预测研究，对农业信息化与气候适应型规划有参考价值，但属区域案例、影响范围有限。",[462],{"name":283,"url":454},[345,30,31,464,465],"气候适应","城市热岛",{"code":35,"slug":36,"name":37,"path":38,"parent_code":39},[],{"status":42,"locked":15,"version":43,"method":44,"evidence":469},{"candidates":470,"agricultural_evidence":49},[471,475,481,485,490],{"code":35,"score":19,"supported":49,"title":472,"abstract":473,"tags":474},[51],[30],[30],{"code":476,"score":56,"supported":49,"title":477,"abstract":478,"tags":480},"H7",[],[464,479],"干旱",[464],{"code":55,"score":56,"supported":49,"title":482,"abstract":483,"tags":484},[],[31,59],[31],{"code":76,"score":77,"supported":49,"title":486,"abstract":487,"tags":489},[],[488],"GIS",[],{"code":370,"score":23,"supported":15,"title":491,"abstract":492,"tags":493},[],[],[345],[495,496],"Landsat 9 城市冷岛 阿尔及利亚","Oued Zenati 城市冷岛 遥感","Landsat9城市冷岛阿尔及利亚-4171","10.1038\u002Fs41598-026-72875-3",{"doi":498,"openalex_id":500,"authors":501,"venue":283,"cited_by_count":92,"oa_url":454,"card":521,"direction":103,"ingested_from":105},"W7218855599",[502,504,506,509,512,515,518],{"name":503,"orcid":9},"Amina Naidja",{"name":505,"orcid":9},"Dalal FARID",{"name":507,"orcid":508},"Djamal Bengusmia","https:\u002F\u002Forcid.org\u002F0000-0003-4480-8637",{"name":510,"orcid":511},"Haythem Dinar","https:\u002F\u002Forcid.org\u002F0000-0002-4504-2963",{"name":513,"orcid":514},"Nouh Rebouh","https:\u002F\u002Forcid.org\u002F0000-0001-6214-2942",{"name":516,"orcid":517},"Imtiyaz Akbar Najar","https:\u002F\u002Forcid.org\u002F0000-0002-7338-6771",{"name":519,"orcid":520},"Nadeem Ahmad Khan","https:\u002F\u002Forcid.org\u002F0000-0003-4366-9639",{"tldr":522,"method":523,"finding":524,"direction":103,"opportunity":525},"用遥感与可解释机器学习预测阿尔及利亚半干旱城市潜在城市冷岛位置。","Landsat 9、Google Earth Engine、GIS与四种机器学习","梯度提升树判别最优（AUC=0.916），冷岛潜力集中于植被与农业区，海拔为最关键预测因子。","可迁移至其他半干旱城市，并引入时序遥感与实地冷岛观测验证，提升模型泛化性。","2026-10-04T23:30:24.545092Z"]
