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.

Abstract The River Ganga and its tributaries are important water resources for North India. It has own ecosystem also creates a unique biodiversity around vicinity. In the past few decades, it been found that huge sediment deposits in basin tributaries. flow area of these rivers is reduced during flooding, inundates large agriculture urban areas. caused economic loss along with human death & displacement. A study was conducted to estimate sedimentation rate areas river systems. Various scientific methods such as surface modelling, satellite imagery interpretation techniques have used. result obtained by indicates continuous rise deposition occurring after year ninety seventy-five more than thirty percent natural channels under threat. highly affected due intervention, especially downstream part basin. Ignoring activities may create environmental, socio-economical tragedy those living method developed findings, study, useful estimating long-term assessment policy development studies.
