解冻期覆沙黄土坡面能量参数与径流产沙关系

open access: yesShuitu Baochi Xuebao, 2021
为探究春季解冻期覆沙黄土坡面能量参数动态响应时空演化过程,在相同放水流量(1 L/min)条件下,采用2个土壤处理(未冻坡面,冻结坡面)和4个覆沙厚度(0,1,2,3 cm)进行室内模拟冷冻和放水冲刷试验,系统分析了径流流速(V)、径流功率(W)、单位径流功率(P)和径流动能(E)在不同土壤处理和不同覆沙厚度条件下的时空演化过程。结果表明:(1)不同处理下的径流流速随产流时间的延长总体呈下降趋势,随着距坡顶距离的增大总体呈增大趋势。未冻坡面和冻结坡面径流流速的均值在0.23~0.35,0.18~0.35
