Prediction of low flow at ungauged sites

Abstract

Low flow prediction at the ungauged site area is important for planning the development water resources management especially that related to power supply or navigation, reservoir design, irrigation, drinking water supply and aquaculture farming. However, the sequent data collection must be collected to able to see the pattern of low flow in future. The purpose of the study to determine low flow at various locations within the tributaries of Sg. Sawak and Sg. Rompin catchment area. Low flow was estimated using 7Q10 equation (estimate the lowest 7 day average flow that occurred on average once every 10 years. The result indicate the 7Q10 in Sg Sawak Catchment and Sg. Pontian Catchment were 0.0179 m3/s in and 0.0067 m3/s respectively.
