The quantity of water yield at a given time is important to identify the amount of water in a catchment area. The objective of this study is to obtain the quantities of water in the watershed of Kelantan. This study focuses on identifying 21 new water catchments based on Soil and Water Assessment Tool (SWAT) model and GIS location of Water Treatment Plant intake. The catchment area features the data relating to each catchment area such as the main river, land lot and area. Subsequently, a simple water balance model was used to obtain the total amount of water in each catchment area in June 2010. This model uses the rainfall and actual evapotranspiration derived from the Tropical Rain Measuring Mission (TRMM 2A25) satellite and the Landsat-5 TM satellite, respectively. The actual evapotranspiration was extracted using the False Color-Composite Model (FCC). This study shows the remote sensing-based water yield model is able to measure the amount of water in June 2010 for 20 catchment areas. Keywords: water yield, Kelantan, landsat-5 TM, TRMM, remote sensing. INTRODUCTION Jabatan Air Negeri Kelantan (JANK), Air Kelantan Sdn Sustainable water resource management is Bhd (AKSB), Department of Drainage and Irrigation defined as “water resource systems designed and managed Malaysia (DID) and Lembaga Kemajuan Pertanian to fully contribute to the objectives of society, now and in Kemubu (KADA) for water resources management. the future, while maintaining their ecological, Besides that, it is also vital for controlling human activities environmental, and hydrological integrity” (Loucks, development within the lack water resources basin areas. 2000). Rapidly increasing of populations combined with un-controllable deforestation, agricultural land expansion, STUDY AREA urbanization and industrialization could lead to critical Kelantan lies between 4o~6oN and 101o~103oE, water shortage issues in the future (Sun et al., 2016). with an area of about 14,922 km2 (Figure-1). It is Therefore, sustainable water resource management should comprises eleven districts, such as Kota Bharu, Pasir Mas, be implemented to secure sufficient water resource for Bachok, Tumpat, Kuala Krai, Tanah Merah, Machang, future generations. Water yield is among the major water Jeli, Gua Musang and Lojing. The Kelantan River flows elements that essential for developing a reliable from south to north into the South China Sea.

The basin is mainly influence government is dedicated to provide an efficient water by the southwest monsoon (SWM) and northeast monsoon supply system for ensuring a high quality lifestyle.

Average annual Malaysia, receives abundant rainfall yearly. However, evapotranspiration rate of the Kelantan state is ranging water-related disasters such as drought and flood are from 1000 to 1600 mm/year. frequently occurs in this region due to high variability of rainfall. For instance, one major drought event has LAND USE DATA occurred in 2014, causing the paddy yield losses of about Three Landsat-5 Thematic Mapper (TM) images USD $22 million (Tan et al., 2017a).

There is no doubt the model is reliable five main instruments including Precipitation Radar (PR), to be used for basin delineation. There are two approaches TRMM Microwave Imager (TMI), Visible Infrared for basin delineation in SWAT model: (1) Digital Scanner (VIRS), Lightning Imaging Sensor (LIS) and Elevation Model (DEM) approach and (2) pre-defined Cloud and Earth’s Radiant Energy System (CERES). The approach where users can define the basin and sub-basins TRMM 2A25 product provides rainfall data in daily scale. manually. We used the DEM-based approach that widely As rainfall is the main input of a hydrological cycle, so the applied in many SWAT studies (e.g. Tan et al., 2014). TRMM 2A25 is used to provide rainfall information of the The Shuttle Radar Topography Mission (SRTM) study area. with an accuracy of ±16m and spatial resolution of 90m is used in this study.

The use of spatial elements in the formation of catchment areas has yet to be fully tested but SWAT model will increase the boundary accuracy of the catchment area Basin delineation function in the Soil and Water as the hydrological modelling process will be connected to Assessment Tool (SWAT) model is used to delineate the each other in each sub-basin.
