terreindrainage
Terreindrainage is the system for removing excess surface and subsurface water from land to improve soil conditions for agriculture, construction, or other land uses. Its primary aim is to prevent waterlogging, improve soil structure, and stabilize foundations by lowering the water table to an appropriate level. Drainage works can be classified as surface drainage, which directs runoff away through open channels, and subsurface drainage, which uses buried drainage pipes or tiles to collect and convey water to outlets.
Surface drainage typically relies on ditches, swales, and channels that capture runoff from rainfall and melting
Design considerations include soil type and permeability, the depth of a water table, topography and slope,
Environmental aspects include potential changes in soil aeration or nutrient leaching, groundwater level impacts, and regulatory
