ABSTRACT
To investigate the effects of various erosion control measures on
mountain floods, a case study was conducted in Censhui River South Branch Watershed using scenario
analysis and soil conservation
service (SCS) methods. A distributed hydrological
model was developed, and watershed
parameters were determined based on satellite imagery, digital terrain models,
digital maps and field investigations. Two types of erosion control measures were investigated: the variation of
vegetation covers and the change of cultivation techniques. Seven scenarios
were considered for the test watershed. The results show: (1) while the
de-vegetation results in the increase of peak discharge, the improve of vegetation covers
decreases peak discharge at watershed scale; (2) by both improving vegetation
cover and enhancing terrace-cultivation technology, the peak discharge is
reduced and the peak flow arrival time is delayed; (3) attention should be attached to both early warning
system and measures changing the underlying surface and conveyance systems.
