WebTime of Concentration refers to the time it takes for all areas of a catchment to start contributing to the flow at the point of the drainage system being considered. This affects the length of the critical design storm. Therefore this value alters depending on the size and shape of the catchment and the length of the drainage system. Webnel movement is unacceptable for the design flow. A threshold channel is a channel in which movement of the channel boundary material is negligible during the design flow. The …
