After the peak runoffrate, sediment concentration decreases and variation amplitude reduces.
峰值径流流量后，含沙量降低，表现为变化幅度小的低含沙量特征。

But the amount of soil erosion or runoffrate was unsignificantly related with the mean rainfall rate in each plot.
平均雨强对各处理区的土壤侵蚀量和径流量均无显著影响。

Therefore, it is scientifically and practically important to develop an automation measurement system which can survey runoffrate real-time and on-line.
