Review on Artificial Bending Cutoff and Regulation of Distorted River Bends

摘要

The distorted river bends often occurs in the lower reaches of the Yellow River, which poses a great threat to the life and property safety of the people in the beach area. It also brings many difficulties to the safe operation and defense of flood discharge and river regulation projects. Scholars at home and abroad have done a lot of research on the abnormal river regime, and have achieved good results by adopting artificial bending and straightening or river engineering regulation measures to control the distorted river bends. After the artificial cutting of Donglu reached the goal of lowering the Tongguan elevation, but the reasonable cutting ratio, cutting section and other conditions should be chosen to achieve successful cutting and good results. In the future, the occurrence mechanism and evolution rule of abnormal river regime should be discussed deeply, and predictive research should be carried out to eliminate or mitigate the harm of abnormal river regime.
