In the context of the effect of drainage density on the run-off generation and the hydrograph at the catchment outlet, all other factors remaining the same, pick one or more CORRECT statement(s) from the choices given below.
- Lower drainage density results in higher peak in flood hydrograph compared to that when the drainage density is higher.
- Lower drainage density results in lower peak in flood hydrograph compared to that when the drainage density is higher.
- Lower drainage density results in a flood hydrograph with a longer time base compared to that when the drainage density is higher.
- Lower drainage density results in a flood hydrograph with a shorter time base compared to that when the drainage density is higher.
