Paper Abstract

Hydropower cascade exploitation in a river basin inevitably makes the spatiotemporal distribution of water resource to change. With Qingjiang River as the test in this paper, two kinds of normalized water indexes have been employed to extract water area from TM/ETM+ imagery so as to quantitatively research the impact on hydropower cascade exploitation for water resource distribution. The results show two models can accurately extract water resource area and both can be used to monitor water resources dynamic change. Before undeveloped in 1987, the total water resource area of Qingjiang River is 60.33km2, and that reaches 110.90km2 in 2004. So, the hydropower cascade exploitation project has a significant impact on the spatiotemporal distribution of water resources in Qingjiang watershed.
