Study on main techniques of water and sediment resources allocation in irrigation system of the Lower Yellow River
摘要
Abstract
The main techniques of water and sediment resources allocation in irrigation system of the Lower Yellow River were summarized, which includes the sediment reduction and sediment sinking technique, water and sediment transport technique, water and sediment diversion teehniqueetc. The sediment reduction and harmful sediment control are stated based on the harmful sediment concept in the irrigation system, of which the former will be realized on controlling diversion sediment concentration or water diversion reduction, and the latter will become true based on the harmful sediment interception and settlement. The structural and non-structural measures for enhancing the sediment transport capacity of the canal are summed through analysis, of which the former includes the slope increase, canal liner, improvement of the flow block bridges and optical cross-section, and the latter consists mainly of water and sediment controlling techniques. The water and sediment diversion characteristics of the gravity irrigation and pumping irrigation were analyzed in theory. When the diversion sediment concentration by gravity in branch canal is less than that in trunk canal, the trunk canal will be in status of deposition increase. When the pumping station and its inlet are arranged suitably, it is good at deposition decrease in the trunk canal.关键词
