EFFECT OF VARIATION OF FRICTION PARAMETER IN OPEN CHANNEL UNSTEADY FLOW

Abstract

In the field of Water Resources Management, it is important to assess the various changes those are likely to occur in canals, river basins, and reservoirs etc. These assessments rayuira a knowledge or Plow characteristics such as stay~a, diacharye, bad slope etc. Because of the unsteady state of flow which is encoun-tered in most of the canals/streams, the bad slope or friction slope changes. Also in practice the flow in a channel is three dimensio-nal and irregular instead of the usual one/two dimensional. In this par an attempt has been made to simulate the three-diman- sional flow velocity and applied to Lakhnauta Minor.....
