The objective of the Programme on Basic Systems in Hydrology (BSH) is to assist NHSs in the development and maintenance of their activities for the provision of data and products with an emphasis on quality assurance, thereby promoting the effective use of hydrological data and information in support of sustainable socio-economic development. It covers the collection, transmission and storage of hydrologic data and their analysis. It is designed to facilitate assessment and appreciation of the socio-economic benefits of hydrological data and information, provision of water-related services and the delivery of warnings. It helps enhance the NHSs’ capabilities and more effectively assess the quantity and quality of a country’s water resources, thereby facilitating rationalization of water management and the achievement of sustainable development. The Programme also promotes the sharing of information on water resources among countries.
