Runoff Change and Its Simulation in Main Stream of Heihe River at Gaoya Section
|
Abstract:
Gaoya section is a control section of main stream of the Heihe River between Ganzhou district and Linze country,Gansu,China,and runoff variation at the section can well reflect the transform between surface water,groundwater and irrigation water in Ganzhou district.Based on qualitative analysis of the components of the runoff,a simplified model is put forward to explain stream channel leakage and groundwater spillage.Monthly water diversion ratio is introduced to describe the intra-annual changes of irrigat...
