长冲河小流域土壤侵蚀与水文泥沙连通性分布特征及耦合关系分析

Shuitu Baochi Xuebao
[目的] 为明确长冲河小流域土壤侵蚀与水文泥沙连通性的分布特征及耦合关系,为该区的水土流失治理、土壤侵蚀科学防治提供依据。[方法] 通过GIS平台,采用RUSLE模型并引入连通性指数(IC)和地形湿度指数(TWI),定量评估长冲河小流域2021年的土壤侵蚀和水文泥沙连通性分布特征,探讨小流域不同坡度、土地利用、高程和坡向对不同土壤侵蚀强度、水文泥沙连通性等级的影响,并通过空间自相关分析土壤侵蚀与水文泥沙连通性的耦合关系。[结果] (1)长冲河小流域平均土壤侵蚀模数为380 t/(hm2·a ...

Local Scour at Grade-control structures under varying Sediment Supply Conditions

工程科学与技术
固床构筑物（矮堰、底槛等）是常用的河道整治措施之一，其修建会改变局部水流结构，引发基础冲刷，威胁其自身结构安全和整治河段的稳定。本研究针对泥沙补给变化下多级固床构筑物基础冲刷特性不清的问题，通过开展一系列概化水槽试验，揭示了不同泥沙补给条件下多级固床构筑物的基础冲刷规律，探明了泥沙补给速率对多级固床构筑物基础冲刷尺度的定量影响，提出了泥沙补给变化下多级固床构筑物基础冲刷深度计算方法。研究表明：无泥沙补给条件下，多级固床构筑物基础冲刷深度先迅速增长后逐渐趋于平衡，其增长速率与结构间距 ...
