Abstract
Abstract A water distribution model is presented which is capable of satisfying water demand in an area with large‐scale mixed cultivation during the water‐shortage periods. The proposed model is based on a new parameter called modified K‐factor in which farm areas, canal and ditch lengths, and crop types are considered. Actual applications show that the proposed model has advantages over the model based on the original K‐factor. The proposed model can deliver appropriate amounts of irrigation water to specific blocks at the right time, fairly and rationally. The model can be applied to either a main or to a lateral canal system. It is found that the water distribution of the main canal system is to be preferred for severe water shortages.
