排水沟的水位和断面排水沟应具有足够的输水能力和适当的设计水位
排水沟的水位和断面排水沟应具有足够的输水能力和适当的设计水位。排水沟的设计水位分为排渍水位和排涝水位两种,排演水位是排水沟平时应维持的水位,主要满足控制地下水的要求。
The level of drainage ditches and cross-section drainage ditches should have sufficient water conveyance capacity and appropriate design water level. The design water level of drainage ditch is divided into drainage water level and drainage water level. The rehearsal water level is the water level that the drainage ditch should maintain at ordinary times, which mainly meets the requirements of groundwater control.

In order to ensure that the water level of the farm ditch is not high, the drainage water level of the bucket, branch and main ditch should be reduced step by step. In addition to the longitudinal gradient of the water flow, there should be an appropriate water level drop at the confluence of all levels of ditches, generally 0.1-10.2 meters. Drainage water level, also known as the highest water level, is the water level when the drainage communicates with the designed discharge
