Abstract

Based on the analysis of influencing factors for water allocation efficiency,and integrating the actual condition of water allocation system of large-sized irrigation district of the Yellow River diversion, the functional relationship between the regional allocation efficiency and water allocation quantity is established using the number of rotational irrigation groups as the parameter.The result of the calculation is compared with that of the present used method and verified according to the data observed.It is proved that the new calculation method is more representative.The specific technological issues of the method in practice use are studied and discussed,which is beneficial for the improvement of water allocation efficiency calculation of large-sized irrigation district.
