Abstract
The main part of a hydroelectric project is the dam with its natural or man made lakes or reservoirs. As in the case of many tropical countries, heavy rainfally and effects of upstream changes in landuse have caused detrimental consequences on the sedimentation. Reservoir Information system, therefore, is recognized presetly as the most suitable and efficient tool to manage the reservoir. The present study will focus on Reservoir Information system for the Pergau Hydroelectric Project, which is located in the State of Kelantan, Malaysia. This paper presents the results of the first phase of the study, i.e. on the data sources and data acquisition techniques in order to develop the Pergau Reservoir Database. The Database will be the major component part of the Pergau Reservoier Information System (PRIS).
Introduction
As in the case in many tropical countries, heavy rainfall and effects of upstream changes in landuse have always caused detrimental consequences on reservoirs. Sedimentation and siltation of particles within the reservoir are the main problems that have been reported by many researchers (Nik et al., 1993). Deposition of this sediment could lessen the reservoir capacity and therefore affecting its economic life (Mustafa, 1987).
Therefore, effective management of reservoir is needed for the purpose of planning and carrying out remedial actions to problems associated within the reservoir. Current trend towards
a more efficient management of reservoir is the application of Geographical Information System (GIS). (Meijerink 1990, suwanwerakamtorn 1994, Bishr & Radwan 1995). Application of GIS will create a system, which may be called a Reservoir Information System for gathering, storing, analyzing and displaying data regarding a particular reservoier. Database which contain all relevant information, is core of the Reservoier Information System.
The objective of this study is to develop a Reservoir Information System for the Pergau Hydroelectric Reservoir, which is located in the state of Kelantan, Malaysia. The study is divided into two phases; (1) the development of Pergau Reservoir Database, and (2) the development of Pergau Reservoir Information system (PRIS). However, this presentation will focus on the implementation of the Phase I of the study.
Study Area
Pergau reservoier is located within the Pergau watershed area, i.e., in the northwest region of the state of Kelantan, Malaysia. This watershed lies approximately within latitudes 5o 35' to 5o 38' N and longitudes 101o 38' to 101o 41' E. Northern part of the watershed is almost bordering with Thailand and the western part is bordering with the state of Perak. This watershed consists of an upper catchment and a lower plain covering an area of approximately 54 km2. The climate in this area is influenced by the northeast and southwest monsoons and annual rainfall is approximately 1200mm in the lower plain, but more in the hilly and mountainous area. Maximum rainfall occurs during septempber to January. The Pergau Reservoir was impounded in the late February 1996, soon after the completion of the Kuala Yong Dam.
