Determining Catchment Area Contour Map. Main land uses (percentage of the total catchment area), contour lines The area of the enclosed figure which results is the catchment area First the line that separates the catchment basin from the rest of area is drawn.

The document discusses how to determine the catchment area or drainage area of a river using contour maps The catchment area of a particular river can be well determined by using the contour map

First the line that separates the catchment basin from the rest of area is drawn. Thus, it is always perpendicular to the contour lines. As an alternative to this graph paper method, we can use Autocad to calculate the catchment area

Simple Contour Map. The watershed line prominently demarcates the drainage basin, traversing through ridges and saddles of the terrain, ultimately encircling the river. Thus, it is always perpendicular to the contour lines.
