This paper investigates the value of observed river discharge data for global-scale hydrological modeling of a number of flow characteristics that are e.g. required for assessing water resources, flood risk and habitat alteration of aquatic ecosystems. An improved version of the WaterGAP Global Hydrology Model (WGHM) was tuned against measured discharge using either the 724-station dataset (V1)...

Water is a limiting factor for economic and social development in most arid semi-arid regions on Earth. The deliberate recharge of depleted aquifer storage later recovery, known as managed (MAR), an important tool water management sustainability . Increasing stresses groundwater subsequent overdrafts have sparked the several advanced MAR technologies, including soil treatment (SAT). SAT method ...

Small reservoirs in arid and semi-arid areas help rural communities to cope with prolonged dry spells. More recently, the construction operation of small has resulted upstream versus downstream water use conflicts some river basins. In this regard, bathymetric information could be used as a tool monitor available surface water, minimize or prevent conflicts. The challenge is that it difficult s...

Relationships between surface waters and groundwaters at basin scale are rarely investigated but have important implications for water resource development management. Here, we integrate evidence from geochemical tracers piezometry to advance the understanding of regional-scale, groundwater–surface interactions in River Awash Basin Ethiopia. Hydrological characteristics consistent with those ob...

Abstract. Previous studies have successfully applied variance decomposition frameworks based on the Budyko equations to determine relative contribution of variability in precipitation, potential evapotranspiration (E0), and total water storage changes (ΔS) (σET2) different timescales; however, effects snowmelt (Qm) vegetation (M) not been incorporated into this framework snow-dependent basins. ...
