Abstract
The diffusive tank model is a quasi-hydraulic model concentration on the continuity relationship among the storage, the inflow and outflow and deals with a flood wave motion as the diffusion wave. As the water level of drainage channels changes very slowly due to a back water effect in a low-lying drainage basin, the unsteady flow in the channel can be simplified to a non-uniform flow.<br>In this paper, runoff analysis by this diffusive tank model in a low-lying drainage area where is about 1.7km2 is carried out. And, after the agricultural refinement of this drainage basin, runoff discharge will be estimated and runoff characteristics from paddies in this field is investigated.
