The area of land drained by a river and its tributaries is called a drainage basin. They are separated from each other by an area of higher ground called a watershed or divide. This watershed determines the direction in which water flows.
Drainage density is typically calculated by dividing the total stream length in a watershed by the area of the watershed. This provides a measure of how well the drainage network is developed within the landscape. Low drainage density indicates less developed drainage patterns, while high drainage density suggests a more well-defined network of streams and rivers.
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.
The Okavango Delta in Botswana is a prominent example of a basin of inland drainage in Africa. It is a unique wetland system that forms in a depressional basin with no outflow to the sea, resulting in water flowing into the area but not draining out.
It's drainage area is 1061469 km.

The boundary of the drainage basin is called a drainage divide. Sometimes drainage basin is called catchment area referring to an area where water flows into a stream or a number of streams. In North America drainage basin is also called Watershed.
Drainage basin is also called catchment, catchment area, catchment basin, drainage area, river basin, and water basin. It is an area of land. All water that falls on that land flows into one river.
