Application of WSJL-0AutomaticMonitoring System in Water Source Monitoring of Slope Runoff Field
Natural slope runoff field is a natural catchment area for observing runoff,which is arranged on representative natural slopes such as topography,soil and vegetation.In order to facilitate research and facilitate the establishment of operational models,observation fields are usually set up in the field for quantitative research.The area varies from tens of square meters to thousands of square meters due to different research scales.Cofferdams should be set around the site to ensure that the catchment area is fixed.There is no water exchange inside and outside the site,and the independence and integrity of the calculation unit are also guaranteed.The traditional runoff is usually monitored by measuring weir or runoff pool for runoff process or total amount,while the real-time online monitoring system is used for automatic monitoring and real-time recording data.According to the principle of runoff formation and the depth of local river channel cutting river,three outlet channels are determined to monitor surface runoff,interflow and underground runoff respectively,and the total runoff and runoff process are calculated on the basis of calculating the runoff of each water source.Runoff field monitoring projects are mainly precipitation,evaporation and runoff.
