【Abstract】 This study designed and developed a new system capable of automatic measuring of runoff. The system integrated the device for filtration,weighing device,water meter,and turbidity sensor. During the exploration,the error of the water meter was corrected,and the feasibility of using the water meter was improved. In addition,the law of turbidity sensor in the determination of runoff and sediment yield was found out. At the end of this article,the source and size of the measurement error of this device are analyzed and discussed,and improvement measures are proposed. After the technology is mature,this device will have a great application prospect in soil and water conservation monitoring.更多还原
