Format: Digital (Free)Fluvial systems provide a wide range of necessary services for human society to thrive on. These are the so-called ecosystem services: food, drinking water, natural flood mitigation, energy and so forth. Such services are linked to an appropriate level of functionality of fluvial processes, which can be accounted for in terms of ecological objectives. These ecological objectives in watercourses can be reached only if appropriate flow and sediment regimes and related quality of channel morphology are guaranteed. The establishment and maintenance of such flow regimes, namely environmental flows ...PermalinkPermalinkThe project was implemented by the World Meteorological Organization (WMO) in collaboration with the National Meteorological Services of Benin, Burkina Faso, Cape Verde, Chad, Côte d´Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone and Togo with funds provided by the Ministry of Foreign Affairs of the Norwegian Government but also by the Government of Greece and minor contributions from AEMET (Spain), EUMETSAT and WMO regular budget.PermalinkPermalink
