Hambantota district in the dry zone can be identified as a severely drought affected area, on the basis of surface water availability. With the ongoing massive development projects in the district, the demand for water will increase significantly in the next few years. Therefore, implementation of a proper water management system is a pre-requisite in facilitating this requirement. The drought severity of Hambantota district was analysed meteorologically, hydrologically and physically using remote sensing and GIS techniques. The combined effect of the above drought components were spatially identified through a matrix overlay operation. The results illustrate that 20% of Hambantota district faces severe water stress conditions, while 11% of the district faces moderate water stress conditions. The resultant drought severity map can be used as a reference in a future water management endeavour to enhance the effectiveness of the project.
