Abstract

A pilot investigation is being conducted to evaluate the current hydroclimatological condition of the Jawi River Basin, Malaysia. The river basin is reported to face physical changes in the near future. The basin area is located in the northern part of Peninsular Malaysia, which lies near to the equator. In this analysis, local climatology information was used since 1990 until 2010 from the Meteorological Office. The design rainstorm intensity was derived from DID Hydrological Procedure No.1, while the Hydrological Procedure No. 12 was used to compute low flows based on regional frequency analysis. The climate of the river basin reflects the equatorial climate with some monsoonal effects. Generally, the highest mean rainfall occurs in the month of October and the lowest rainfall occurs in the month of January. The 7 day low flow value for the basin is about 0.062 cubic meter per second cumecs . This means that the river basin should maintain the stream discharge at least 0.062 cumecs or above to prevent any adverse ecological impacts on the waterbody and its ecosystem.
