基于畦首水深和田面水流推进过程的畦灌流量反演方法
Inversion method of border flow based on headwater depth and advance process of surface water flow
摘要
Abstract
Aimed at the problem that the single wide flow is difficult to measure without interference in robust design of border irrigation system,the paper analyzed the inversion method of border flow rate.The infiltration parameters were estimated by two point method based on the data collected in Nanpi Eco-Agriculture experimental station.Then it estimated the single wide flow based on the data of border headwater depth and water advance process,and introduced two parameters of surface shape factor and underground shape factor.Compared with the measured single wide flow,the relative errors in N1,N2 and N3 border are 13.27％,8.02％ and 11.24％ respectively.Results show that the inversion method is feasible for error control of single wide flow in the robust design of border irrigation.关键词
