ADHI: the African Database of Hydrometric Indices (1950–2018)

Abstract. The African continent is probably the one with lowest density of hydrometric stations currently measuring river discharge despite fact that number operating was quite important until 1970s. This new Database Hydrometric Indices (ADHI) provides a wide range indices and hydrological signatures computed from different sources data after quality control. It includes 1466 at least 10 years daily over period 1950–2018. average record length 33 years, 131 have complete records 50 years. With this dataset spanning most climatic regions continent, several been computed, representing mean flow characteristics extremes (low flows floods), are accessible to scientific community. database will be updated on regular basis include more longer time series discharge. ADHI available for download at: https://doi.org/10.23708/LXGXQ9 (Tramblay Rouché, 2020).
