Description
Summary:Under normal conditions, drainage problems in humid regions may be caused by shallow groundwater levels resulting from high precipitation rates. A high groundwater level may, however, also result from several other factors, such as soil properties, especially a low hydraulic conductivity, and the field conditions with regard to the outlet of drainage water into a river. This type of drainage problem may occur in flat as well as mountainous areas, but there are other possible reasons for drainage problems in the latter case. When the problem in a mountainous area is caused by high rainfall, a parallel drain system may suffice. In the case of inflowing groundwater, interceptor drains may be a solution, but location and depth are determining factors for their effectiveness. Another problem in mountainous areas concerns landslides that occur under high groundwater pressure, especially where the thickness of the topsoil is small and the slope of the surface is steep. Deformed tree trunks are good indicators for such places.
