With the construction of the monitoring system of the middle and small rivers, a large number of monitoring stations have been built, the existing base station staff and the traditional hydrological test methods have been difficult to meet the requirements of the increasingly heavy hydrological monitoring tasks. Through the laying head hydrology hydrologic data of station and station, analyzes the characteristics and patrol measurement and analysis, to carry out the hydrologic measuring operation, to meet the precision of hydrological test and reorganize data precision, greatly reduce the labor intensity of the hydrological monitoring.
