1. Meteorological & Hydrological data for water resources development

2. Hydrology is the study of the movement, distribution, and quality of water on Earth and other planets. It includes hydrological cycle, water resources, environmental watershed ability. Application: Determining the water balance of a region.water balance Determining the agricultural water balance.agricultural water balance Assessing the impacts of natural and anthropogenic environmental change on water resources.water resources Assessing contaminant transport risk and establishing environmental policy guidelines.contaminant

3. 3 What is the role of hydrology for water resources management? Estimation of water resources availability Estimation and reduction of hydrological risks Development of hydrological scenarios Ensure proper information to decision makers

4. Meteorology is the study of atmosphere, – Climate changes – Precipitation & ET – Runoff – Temperature, air pressure & water vapor. Application: Weather forecasting Aviation meteorology Agricultural meteorology Hydrometeorology Maritime meteorology

5. Meteorology functions National Weather Service National Tsunami Alert Service National Tidal Centre National Flood Warning and Forecasting Service National Climate Monitoring System National Ocean Current Prediction National Water Information Service Climate and Meteorological Research (with CSIRO) Climate and Meteorological Research (with CSIRO) DATA

6. Role of the Hydro-Meteorological Services Risk TransferRisk Assessment Historical Hazard databases Hazard statistics Climate forecasting and forward looking hazard trend analysis Exposed assets & vulnerability Risk analysis tools Preparedness (saving lives): early warning systems emergency planning and response Prevention (Reduction of economic losses): Medium to long term sectoral planning (e.g. zoning, infrastructure, agriculture) Catastrophe insurance & bonds Weather-indexed insurance and derivatives Risk Reduction Information and Knowledge Sharing Education and training across agencies Alignment of clear policies, legislation, planning, resources at national to local Levels (Multi-sectoral, Multi-agency) 3 2 5 4 1 6
