Monitoring and managing groundwater resources is critical for sustaining livelihoods supporting various human activities, including irrigation drinking water supply. The most common method of monitoring well level measurements. These records can be difficult to collect maintain, especially in countries with limited infrastructure resources. However, long-term data collection required characterize evaluate trends. To address these challenges, we propose a framework that uses from the Gravity Recovery Climate Experiment (GRACE) mission downscaling models generate higher-resolution (1 km) predictions. designed flexible, allowing users implement any machine learning model interest. We selected four models: deep model, gradient tree boosting, multi-layer perceptron, k-nearest neighbors regressor. effectiveness framework, offer case study Sunflower County, Mississippi, using validate Overall, this paper provides valuable contribution field resource management by demonstrating remote sensing techniques improve resource, those who seek faster way begin use datasets applications.

Abstract Groundwater remains the most dependable resource for various essential uses such as drinking, cleansing, agricultural irrigation, and industrial applications. In urban areas, dependency on groundwater to meet water demands is significant. However, this faces threats from overuse poor management, leading a degradation in quality primarily due unchecked release of household wastes. The escalation activities rapid growth have amplified volume wastewater, adversely affecting purity freshwater sources within aquifers. This investigation focuses evaluating impact effluents city Faisalabad. main contributors pollution include indiscriminate disposal through unlined drains extensive application chemical agents agriculture, fertilizers, pesticides. To understand physiochemical properties both, drain groundwater, samples were collected at distances 50 m, 100 150 m outlets. study utilized Geographic Information Systems (GIS) accurately map analyze distribution contaminants. Parameters pH, electrical conductivity (EC), total dissolved solids (TDS), hardness, bicarbonates, calcium magnesium chloride levels examined. findings indicated that contaminant highest increased concentration closer they drainage sources, with exception pH levels. All exceeded World Health Organization's (WHO) safe limits, deeming them unfit use. finding indicates widespread contamination, posing significant public health risks highlighting urgent need improved waste management treatment practices It underscores critical importance implementing effective control measures safeguard ensure security region. notable correlation was observed between pollutants key indicators EC, TDS, their role deteriorating aquifer quality. Moreover, exhibited pollutant concentrations compared those taken further away, distances.

Monitoring and predicting the regional groundwater storage (GWS) fluctuation is an essential support for effectively managing water resources. Therefore, taking Shandong Province as example, data from Gravity Recovery Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) used to invert GWS January 2003 December 2022 together with Watergap Global Hydrological Model (WGHM), in-situ volume level data. The spatio-temporal characteristics are decomposed using Independent Components Analysis (ICA), impact factors, such precipitation human activities, which also analyzed. To predict short-time changes of GWS, Support Vector Machines (SVM) adopted three commonly methods Long Short-Term Memory (LSTM), Singular Spectrum (SSA), Auto-Regressive Moving Average (ARMA), comparison. results show that: (1) loss intensity western significantly greater than those in coastal areas. From 2006, increased sharply; during 2007 2014, there exists a rate - 5.80 ± 2.28 mm/a GWS; linear trend change 5.39 3.65 2015 2022, may be mainly due effect South-to-North Water Diversion Project. correlation coefficient between WGHM 0.67, consistent level.

Extreme precipitation events have caused severe societal, economic and environmental impacts through the disasters of floods, flash-floods landslides. However, coarse-resolution satellite-derived data makes it difficult to quantitatively capture certain fine-scale heavy rainfall process. Therefore, improve spatial resolution accuracy satellite-based extremes, a downscaling-calibration scheme based on eXtreme Gradient Boosting (XGBoost_DC) was proposed in this study, where XGBoost algorithm applied both downscaling calibration procedures. The performance XGBoost_DC evaluated with other two comparative methods, which only used either (XGBoost_Spline) or (Spline_XGBoost) results showed that: (i) achieved best performance, as obtained highest well reproduced occurrence distribution during typhoon events. (ii) could variations precipitation. Although Spline_XGBoost slightly worse than XGBoost_DC, significantly underestimated variability. (iii) model assessment between illustrated essential contribution process, improved our understanding capability machine learning reproducing variance These findings imply that can be for generating high-resolution high-quality extremes events, would benefit water flood management, various applications hydrological meteorological modelling.
