Dams are vital for irrigation, power generation, and domestic water needs, but siltation poses a significant challenge, especially in areas prone to erosion, potentially shortening dam’s lifespan. The Ahmed El Hansali Dam Morocco faces heightened due its upstream region being susceptible erosion-prone rocks high runoff. This study estimates the at dam from construction up 2014 using bathymetric data Brown model, which is widely-used empirical model that calculates reservoir trap efficiency. Additionally, evaluates impact of Land Use Cover (LULC) changes projected future rainfall until around 2076 based on rates. results indicate LULC, particularly temporal variations precipitation, have dam. Notably, strongly correlated with rate, an R2 0.92. efficiency sediment trapping (TE) 97.64%, meaning 97.64% catchment area trapped or deposited bottom estimated annual specific yield about 32,345.79 tons/km2/yr, accumulation rate approximately 4.75 Mm3/yr. half-life be 2076, precipitation projections may extend this timeframe strong correlation between precipitation. soil erosion driven by land management practices plays crucial role dynamics. Hence, offers comprehensive assessment dynamics dam, providing essential information long-term effects use changes, climate projections. These findings assist decision makers managing sedimentation more effectively, ensuring durability extending life.

Groundwater is the most important source of freshwater next to surface water. Delineation groundwater potential critically essential, particularly in hilly complex topographic regions, where water dries up during dry season. The present study aimed delineate areas address issue scarcity Serchhip district, Mizoram. integration different thematic layers such as lithology, Normalized Difference Vegetation Index (NDVI), rainfall, slope, soil texture, geomorphology, drainage density, lineament density and Topographic Wetness (TWI), zone was prepared by Analytical Hierarchy Process (AHP) method. zones (GWPZ) were classified into five: poor, fair, moderate, good, excellent. revealed that moderate-good occupied about 79.27 % (1126.77 km2), fair covered an area 9.52 (135.3 km²), while poor only 5.30 (75.3 km²) out total (1421.5 km2). demarcation Serchhip, Mizoram, served combat mountainous areas. amalgamation geospatial data AHP methodologies offered pivotal insights for sustainable management resources, facilitating informed decision-making conservation endeavours amidst challenges posed climate fluctuations population expansion.

This study aims to highlight the quantitative analysis of Middle Tuirial watershed in Mizoram, India and its significance for soil loss risk. In addition understanding landscape evolution hydrological characteristics river basin, it is crucial implement appropriate water conservation practices, reduce further erosion risk basin. Linear, areal relief aspects morphometric parameters were analyzed using a survey topographical maps, advanced land observing satellite (ALOS) phased array type L-band synthetic aperture radar (PALSAR) digital elevation model (DEM), geographic information system (GIS). The reveals high drainage density 5.22 km/km2 stream frequency 10.58 km2, which denotes basin exhibits surface run-off with low groundwater recharge. addition, has 0.6 form factor, 0.3 elongated ratio 0.43 circularity indicating highly shape Furthermore, hypsometric integral values 0.48 an s-curve show attained mature stage evolution.
