Hydrological studies for the North Central Province of Sri Lanka cover an important and vital component of the overall assessment of land and water resources potential. In order to make an assessment of water resources of the river basins of the North Central Province, the collection of all hydro meteorological observations of the study area and the compiling and estimation of long term characteristics of the variables such as rainfall runoff forms the scope for the preparation of a complete resource assessment. In order to fulfill the above requirement, information on all hydro meteorological observations, some details of existing irrigation schemes and other water projects in individual river basins have to be collected and documented. It is also expected to carry out limited studies to interpret the hydrological process in the region, such as long term variation of rainfall and river flows. This study collected time series hydrological data such as rainfall, stream flow, pan evaporation on a monthly basis and prepared a map showing the hydrometric network in the NCP area. It also identified and documented the present gaps in the hydrological database and the deficiencies in the present hydrological data collection network relevant to the watersheds. It is expected to develop a proposal for a long-term hydrological data collection programme for the NCP based on this study.
