Abstract:

At present, the traditional Kostiakov formula is used to calculate the leakage of water channel. But it also has obvious deficiency, namely the operation aging of channel seepage is neglected and relevant formula parameters are not in conformity with the actual situation in China. In view of the above problems, a new method with mathematical regression analysis is carried out, and the flow measuring method, software, measuring points arrangement and data collection and analysis associated with this method are introduced. The leakage calculation in one typical irrigation districts shows that improving the traditional empirical formula by regression analysis method can obtain ideal results with high accuracy.
