Khairul Anam Bin Musa @ Mahmud
KhairulAnam Musa graduated from UniversitiSains Malaysia (USM) in 1994 with B.App.Sc. (Hons) degree in Geophysics and then attended the National University of Malaysia (UKM) where he awarded the M.Sc. degree in Geology in 2001. He joined Malaysian Centre for Remote Sensing (MACRES), now known as Malaysian Remote Sensing Agency (ARSM) in 1994 as Research Officer for 14 years involved in remote sensing and GIS technologies focusing in Geosciences Applications such as Groundwater, Mineral and Landslide. He then joined National Hydraulic Research Institute of Malaysia (NAHRIM) as Senior Research Officer and involved in Groundwater, Hydro-climate Change Projection and Modelling, and Rainwater Harvesting Research Projects.

The Value of Geospatial Technologies in Water Resources and Climate Change Research
Climate change is making the headlines all over the world with the increasing severity and frequency of meteorological disasters such as the polar vortex, typhoons, and heat waves. These disasters are correlated to changes on global water cycle or water resources on local scale. The global and geographic nature of climatic systems has propelled geospatial technologies to the forefront. In climate change research, Global Climate Models (GCMs) – using satellite and other geospatial data – is able to simulate the climate of the earth and project future climate in terms of parameters such as precipitation, temperature and solar radiation. To determine the impact of climate change to water resources, large-scaled GCM resolution need to be downscaled to regional scale. These projected hydro-meteorological data, together with geospatial data such as Digital Elevation Model (DEM), river network and land-use map were entered into a hydrologic model to simulate future flood flow magnitude. A 2D hydraulic model, together with satellite imagery and population data, can simulate the flood extent and subsequently map out the population affected and economic losses of the projected floods. The outcome from these studies will be able to reduce water-related disasters, enhance the resilience of water-related infrastructure and improve the resilience of communities in the context of climate change adaptation. In general, this paper will discuss on the process and application of geospatial data in quantifying the impact of climate change on water resources, particularly in terms of flood magnitude. This paper will also highlight the availability of NAHRIM’s climate projection data through the Future Hydroclimate Database and Simulated HydroclimateGeoinformation System.
