| Abstract: | This year summer, flood hazard once again occurred in the Chanqjiang River. The flood control works has standed severe test. The envronmental geological problems are becoming serious increasingly. This is one of the reasons Why flood hazard has been aggravated. This paper has analysed soil erosion, riverand lakes deposit, land subsidence of environmental geological problems in middle and lower reaches of the Changjiang River and expounded its effects to flood control works. |
| Keywords: | middle and lower reaches of the Changjiang River flood control works flood hazard environmental geological problems soil erosion river and lake deposit land subsidence |
