The trees in the drainage basin area would intercept and delay the discharge of the drainage basin but since there are no trees around, the water will just flow very fast, which can cause surface run offs.
Conservation authorities based on drainage basins are useful because they maintain secure supplies of clean water, protect communities from flooding and contribute to municipal planning processes to protect water. The Canadian Conservation Authorities Act was passed in 1946 to join communities in the same watershed area (rivers that flow to the same drainage basin) to help the communities undertake programs of natural resource management.
Yes, topographic map should help with your drainage problem, as it will allow you to see if there are any blockages and/or damaged pipes in your area.
Reforestation is especially important in the headwater parts of a river's drainage basin. To help control flooding near a river's mouth, spillways are used.These are channels that run through the back swamps parallel to the main stream.
Moss can help loosen clay soils and promote drainage.
