Discussion on Harnessing Measures of the Xiaobeiganliu Reaches of the Yellow River

摘要

In recent years the silting in the Xiaobeiganliu reaches of the Yellow River has been serious,causing new problems to river flood control,engineering layout and works defense.Based on the practice of the Yellow River harnessing,this paper analyzes the problems existing in the harnessing of the Xiaobeiganliu reaches of the Yellow River in six aspects,namely,the channel flood discharge capacity has declined,the river pattern can not be effectively controlled,the phenomenon of serious danger caused by mere small flood has occurred frequently,the floodplain land suffered from serious salinization,the construction standard of flood control roads were too low and the construction of flood control non-engineering measures has lagged behind.It is put forward such harnessing measures as: carrying out water and sediment regulation; carrying out research on the law of "bottom tearing" scouring; speeding up construction of river harnessing projects; building village protective projects; raising construction standard of floodplain roads; making preparation earlier for flood control emergency rescue; and strengthen construction of flood control non-engineering measures.
