Measurement concepts

Abstract

As discussed in chapter I-3, the climatic, ecological, and hydrologic environments in the Ouémé and Drâa catchments are very different. A scarcity of hydro-meteorological and vegetation data is common to both regions and is typical for many African catchments, both for spatial density of measurement stations and for longterm homogeneous time series. These data are necessary for process studies, trend analyses, as well as for model initialization and validation. The measurement concepts developed within IMPETUS incorporated these challenges and provided a database for knowledge-based adaptations to a changing environment. © 2010 Springer-Verlag Berlin Heidelberg.
