Study on Green Water Management in a Typical Watershed in Water Resource Area of the Mid-Route of South-to-North Water Transfer

Abstract:

Danjiangkou Reservoir and its upstream tributaries as water resource area is of strategic importance for the Mid-route of South-to-North Water Transfer Project. Water conservation and water purification is the key measures for sustainable water diversion. Green water management as a new technologies to achieve water conservation and water purification has a broad application prospects. In this research, green water management was studied in the Upper Du watershed. ArcSWAT model was used to assess quantity of green water resource. By adjusting the model parameters, the efficiency of different green water management scenarios on water and soil conservation were simulated. The results of the study indicate that the quantity of green water in the Upper Du is about 5.588 billion cubic meters. Mulching is a better green water management way that more suitable for water and soil conservation in the Danjiangkou Water Resource Area. This research can provide a reference for water resource protection and management in Water Resource Area of the Mid-route of South-to-North Water Transfer.
