The widespread and relentless discharge of untreated wastewater into the Upper Litani Basin (ULB) river system in Lebanon has reached staggering levels rendering its water unfit for most uses especially during the drier times of the year. Despite the call by governmental and non-governmental agencies to develop several wastewater treatment plants and sewage networks in an effort to control this...

At present, there are still problems, such as uneven regional distribution and low per capita ownership of water resources in the Pearl River Delta, so solving problem resource allocation is a hot spot that needs continuous attention region today. For long time, many experts scholars have proposed models WEAP (Water Resources Assessment Planning) SWAT (Soil Water Tool). Based on advantages disa...

The Lam Phaniang River Basin is one of the areas in Northeast Thailand that experiences persistent drought almost every year. Therefore, this study was focused on assessment severity and vulnerability Basin. evaluation based Drought Hazard Index (DHI), which derived from Standardized Precipitation-Evapotranspiration (SPEI) calculated for 3-month (short-term), 12-month (intermediate-term), 24-mo...

Reservoir management decisions are commonly made using surface water models with simplified and/or abstracted physical processes and limited groundwater-surface water interactions. Optimizations with such models might not capture the potential importance of and feedbacks from physical processes such as evaporation and infiltration. This study details how management algorithms of the Water Evalu...
