摘要

将水库淤积按沉积动力学特征分为河流沉积动力淤积和水库沉积动力淤积2种类型

建立了2种淤积类型的动力模型。水库淤积量的大小按水库因水位下降所出露的淤积物面积进行评估。结合陆地卫星TM图像

对研究区内的30个水库

按淤积程度离差分为3级: 级

DEPDEV<-0.3; 级

DEPDEV=-0.3～1; 级

DEPDEV>1。对比图像平面数据与实测的水库淤积量数据

发现图像数据与兴利库容以下实测数据协同性好。

Abstract

Reservoir silting can be divided according to sediment dynamics into two basic types-reservoir (hydrodynamic) silting and river hydrodynamic silting

for which two types of sediment models can be constructed. The area of silting in reservoirs was estimated by measuring the area exposed during low water level periods. Statistical data was collected from 30 reservoirs through the combination of Landsat images. Silting degrees were divided into three grades: gradeⅠ

silting degree DEPDEV＜-0.3; gradeⅡ

silting degree DEPDEV=-0.3～1; grade Ⅲ

silting degree DEPDEV＞1. The results establish the characteristics of silting degrees in the larger drainage area.
