Hydrologieal Effects of Farmland Drainage Project in Black Earth with Nodular Kankar in Northern Huai Plain |
| |
| Abstract: | Upon analysing experimental data of about 20 observation stations with different catchment area and various project standard, an empirical formula calculating draining modulus of extremly small catchment is presented, ditch parameters and layout of the drainage system are suggested for practical use from the point of view of hydro-logical effects. |
