3. Validation of Manning’s n equations for a swale with a subdrainage channel as water storage

Khairul Rahmah Ayub; Aminuddin Ab. Ghani

Volume 2, Issue 1 , Autumn 2021, Pages 31-38

http://dx.doi.org/10.22034/wpj.2021.303814.1043

Abstract
  In stormwater management systems, a swale is one of the flow control-at-source facilities. The application of swale with a subdrainage channel in Malaysia urban areas is new and promising to control urban flash floods. Rainfall-runoff infiltrate to the subdrainage can be stored and become proper irrigation ...  Read More
