With advanced of remote sensing, these parameter can be collected with better spatial & temporal restriction.In such humid tropical rainforest country like Malaysia, water-yield exists in a bundle that it remains as the major sources for cumulative water collection in the catchment. To obtain it, several steps required such as 1) Acquisition and compilation of various satellite remote sensing data at different spatial and temporal resolution. 2) Satellite data pre-processing involving radiometric and geometric correction and data calibration and validation with in-situ observations. 3) Qualitative and quantitative assessment of precipitation and evaporation products extracted from remote sensing data.It has become an interest to calculate how much the capability of catchment in Malaysia to supply water and sustain it. Several challenges exist and need to be overcome. With these limitations this research aims to create an option for monitoring water security not in a single location but is wide distribution from satellite input. From there, better water management and water supply can meet the demands during drought and monsoon season events. |
