Meteorological & Hydrological data for water resources

development

• 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.Determining the agricultural water balance.Assessing the impacts of natural and anthropogenic environmental change on water resources.Assessing contaminant transport risk and establishing environmental policy guidelines.

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

• Meteorology is the study of atmosphere,– Climate changes– Precipitation & ET– Runoff– Temperature, air pressure & water vapor.
