Abstract
Ecological water use EWU is urgent in need in the lower reaches of Tarim River in China Estimation of water amount for EWU is depending on some parameters and modeling EWU is mainly consists of two parts in no runoff area in the basin ie total water amount for restoration groundwater table and total stand water amount of the all river courses The former is including water amount for restoration of groundwater table lateral discharge and evaporation of water surface The estimated values are 818 × 108 m3 068 × 108 m3/a and 0132 × 108 m3/a respectively Based on the groundwater depth rising 40 meters requiring 5 years the total water amount for restoration groundwater table is 2448 × 108 m3/a The latter ie total stand water amount is 1992 × 108 m3/a However the development of water management measures could alleviate the issue and lead to sustainable EWU in the lower reaches of Tarim River
