Design of Integrated Equipment on Runoff and Sediment
摘要
Abstract
The observation error of soil loss by water erosion was high under artificial method,hence well mixed sediment in runoff is the dominant process of runoff sample collection.We developed a movable runoff collector.In order to collect a well mixed sediment sample,the parameters of runoff sediment mixing component of the equipment were tested,thereby the optimal height and diameter of the mixing barrel were confirmed.Results showed that sediment in runoff was best mixed in the first split barrel with the height 150 mm(H150) combined with the diameter 200 mm(Φ200).The sample error was less than 16%;and the height 40 mm(H40) combined with the diameter 60 mm(Φ60) of the second split barrel had the optimal mixing effect of sediment in runoff,whose error was less than 7%.The mixing effect of sediment in runoff could be greatly enhanced under an appropriate height and diameter of the mixing barrel.This measurement provided good parameters for the design of equipment for mixing sediment in runoff.关键词
