NAMWA : a new integrated river basin information system
NAMWA provides information about the interlinkages between the physical water system and the economy at national and river basin scale. This involves not only linking water related environmental data to economic data, but also presenting these data at the relevant geographical scale through upscaling or downscaling. It is this issue of matching available data across the various scales, which has proven to be one of the major challenges in the compilation of a new integrated river basin information system.
