High drainage density means
Web4 de mar. de 2024 · In order to calculate drainage density for a basin or sub-basin, you must first ensure that you have the lengths of all channels within the basin’s boundaries (rivers, streams, etc.), as well as the area for the entire basin. Drainage density is calculated using the formula: Drainage Density = total length channels (m) = m-1. Webdrainage density in the form of Q2 .ss per mi2 =1.3D2. The close relation of mean annual flood to drainage density in 15 basins was not affected by large differences among the basins in relief, valley-side slope, stream slope, or amount and intensity of precipitation. It is concluded that drainage density is adjusted
