Les bassins versants de recherche tropicaux: historique des études menées par l'Orstom

Tropical research basins: a history of the Orstom studies Abstract About 350 small representative basins were studied by Orstom hydrologists during the early 1950s in the intertropical area. The first research was mainly oriented to development, but in 1965 Rodier & Auvray put forward graphs permitting the calculation of the design characteristics for small basins in tropical Africa. In the 1970s, evaluating the c water balance » became important with the appearance of the first mathematical models allowing the management of data sets
