摘要:
浑水与清水的水流特性有差异。但实验分析研究结果表明，在本实验条件下（比降1/82，有机玻璃矩形槽，含沙量0~245.5kg/m3，流量（5.01/s，槽内水流属粗糙紊流急流流态，且距槽尾47～102cm的槽段为恒定均匀流），含沙量未对实验槽的糙率及水位流关系产生影响，槽内也未产生泥沙淤积，从而精确地确定了清水和浑水的糙率及其相应的水位流量关系计算公式，可供土壤侵蚀，模拟模型测定水土流失量应用。本文就含沙量对糙率和水位流量关系影响的初步分析和探讨，可供有关研究参考。
Abstract:
Flow characteristics of mud water and clear water are different. But the results of experimental analysis and research showed:at the experimental conditions (descending ratio is 1/82 in rectangle channel made in plastic glass, silt concentration is 0-245.5kg/m3, flow volume is less then 51/s,water flow is flow pattern of rough and turbulent flow in the channel, but flow pattern of 47-102cm distance to channel end is steable and uniform flow),silt concentration did not affect on roughness in the channel and relation between water level and flow volume, silt deposition in the channel did not produce. And calculation formulars for roughness of clear water and mud water and their relation of water level and flow Volume have been precisely establshed.Those formulars can be used to determine soil loss in soil erosion simulation model. impact of silt concentration on roughmess and relation between water level and flow volumun can be reference in related research.
