Soil erosion is exacerbated by unsustainable land-use activities and poor management practices, undermining reservoir storage capacity. To this effect, appropriate estimation of sediment would help to adopt sustainable best practices that lead efficient operations. This paper aims investigate the spatial variability yield, amount delivery into reservoir, sedimentation in Koga Reservoir using Water Assessment Tool (SWAT). Sediment yield entered were also estimated a rating curve, providing an...

The rapid intensification of drought, commonly known as flash has recently drawn widespread attention from researchers. However, how the characteristics and drivers, well ecological impacts rapidly intensified droughts, differ those slowly ones still remains unclear over globe. To this end, we defined three types droughts based on root zone soil moisture (RZSM) decline rates, general creep then implemented a comparative analysis between them across globe 26 Intergovernmental Panel Climate...

East Africa (EA), lake basins (Tana, Abaya-Chamo, Turkana, Victoria, and Tanganyika), 6472,404 km2 of total area. Total water storage change (TWSC) exposes serious challenges in sustainable resources management ecosystem sustenance. While TWS changes have been increasingly studied based on Gravity Recovery Climate Experiment (GRACE) derived dataset, spatio-temporal the driving factors remain unexplored. Herein, Mann–Kendall test, Theil-Sen's slope estimator, empirical orthogonal functions...

Understanding the spatiotemporal trend of land cover (LC) change and its impact on humans environment is essential for decision making ecosystem conservation. Land degradation generally accelerates overland flow, reducing soil moisture base flow recharge, increasing sediment erosion transport, thereby affecting entire basin hydrology. In this study, we analyzed watershed-scale processes in study area, where agriculture natural shrub are dominant LCs. The objective was to assess time series...

Accurately estimating aboveground biomass (AGB) is essential for assessing the ecological functions of coastal wetlands, and AGB wetlands affected by Land use/land cover (LULC) types conversion. To address this issue, in current study, we used Boreal Ecosystem Productivity Simulator (BEPS) model to simulate Yellow River Delta during 2000–2015. Based on LULC transform, analyzed spatiotemporal dynamics simulation results their relationship with human-nature driving process. At same time,...

Hydrological drought, a regular phenomenon that could have major impact on natural systems and human life, is aggravated by water storage deficit. While Gravity Recovery Climate Experiment (GRACE) satellite data-based drought monitoring has been widely studied in East Africa (EA), recovery time anthropogenic factors, prerequisite for management, are still missing. Here, deficit index (WSDI) modified WSDI were utilized analyzing holistic representation of drought. The results show the events...
