Hydrology Initiatives

Surface runoff estimation from a watershed is a prerequisite for surface water assessment. Hydrological models are the only tool to assess the flow from a watershed under different scenarios. The Soil and Water Assessment Tool (SWAT), a physically based hydrological model, is used modelling monthly streamflow in Altuma catchment. The model was calibrated from 1985 to 1996. Initial 3 years from 1985 to 1987 were taken as warm up periods. Then the model was validated for 7 years from 1997 to 2003.

The International Hydrological Programme (IHP), a UNESCO’s intergovernmental scientific co-operative programme in hydrology, is a vehicle through which Member States can upgrade their knowledge of the water cycle and thereby increase their capacity to better manage and develop their water resources. It is the only intergovernmental programme of the UN system devoted to the scientific, educational and capacity building aspects of hydrology.

Over the past decade, many countries have been upgrading their water monitoring systems and their data collection efforts, supported with new information technologies and web‑based communication. A review of the information demands arising from OECD work, shows that important gaps still remain. The quality of water data currently available at national and international level is insufficient to effectively support integrated water management and water policies.

The Earth environment derives from a unique combination of factors favouring the development of various landscapes and life forms. The activity of the meteorological, geophysical or hydrological factors is characterized by variations of different amplitudes and frequencies that can provoke severe disequilibrium to a given ecosystem. Disasters can arise anywhere at the crossroads between natural hazards and human society, as a combined result of the strength of extreme events and a fragile, unprepared community....
