This study develops a flow direction prediction model using Sentinel-1 satellite imagery during rainy and dry seasons through the Random Forest machine learning algorithm. The pre-processing stage includes radiometric calibration, terrain flattening, speckle filtering, Doppler correction. processed DEM data is used to extract key topographic parameters: elevation, slope, curvature, which are then utilized in model. built with 500 trees (n.trees), mtry of 2 for season 3 season, out-of-bag (OOB) error estimates 8.76% 9.32%, respectively. Model evaluation, conducted confusion matrix, reveals high performance, average Overall Accuracy, Kappa User Sensitivity, Specificity all at 0.98 or above. analysis shows that predominantly shifts northeast (16.48%), while it northwest (16.85%). Slope significantly influences direction, feature importance scores 60.76% 63.53% season. crucial as dictates speed water under gravity. could contribute geothermal field management by accurately predicting surface flow, enhancing monitoring, promoting sustainable resource management.

In this paper, four cities in India having different geographical structures, climates, and hydrological components were selected. An area of 500 m 2 from each city has been studied. A mathematical model with three-dimensional hydraulic conductivity, head the aquifer, other factors was adopted, which additional artificial recharge added. The is numerically solved help C++ software, details provided Appendix, graphs plotted to depict status groundwater level after recharge. It found that during study period 2014 2021, increase Bhopal 9 m, for Jaipur 6 Dehradun 6.5 Bangalore 5 m.

Abstract This study investigates toxic metal contamination in the sediments of Değirmendere River Basin (riverbed and estuary) Türkiye, with aim assessing pollution levels, ecological risks, seasonal variability concentrations. Sediment samples were collected from 20 stations during summer winter 2022 analyzed using geochemical statistical methods. The metals evaluated include Cu, Pb, Zn, Ni, As, Co, V, La. findings reveal that Cu (79.46 ± 20.17 μg g -1 ) Pb (63.83 15.11 exceeded thresholds, highest concentrations observed winter, particularly estuarine areas affected by industrial urban activities. Seasonal variations significant for Zn (Mann-Whitney U, p < 0.05), higher likely due to increased runoff erosion. Geoaccumulation Index (I geo Enrichment Factor (SEF) indicated moderate As. risk index (RI) categorized estuary as a considerable area, RI values ranging 150 319.2. These highlight anthropogenic impacts on sediment quality Basin, emphasizing urgent need continuous monitoring targeted mitigation measures.
