Assessing Environmental Flows In Data-Poor Rivers: An Example Of The Wami River Estuary, Sadaani National Park, Tanzania.
In much of the world, there is little information on hydrological linkages with ecosystem structure/function. While studies to characterize flow requirements of individual species and communities are important, the urgency posed by ever-increasing water demands calls for environmental flow guidelines to avoid irreversible ecosystem degradation. We describe an approach to obtain an initial set of flow recommendations for the Wami River in Sadaani National Park, Tanzania, based on the assumption that, if a river has a diverse ecosystem, the flows over the past 30-40 years have maintained the ecosystem. Hence, flow data over this period can give an initial idea of the natural flow regime occurring in the river that have shaped the ecosystem. Rapid ecohydrological field assessments and local resident interviews provide a broad understanding of the distribution of riparian, floodplain and aquatic communities in conjunction with seasonal water level. Hydrological modeling then indicates the extent of flooding with a given water level. All this information is then combined to create environmental flow guidelines on a monthly scale, for years with normal rainfall and years with below-normal rainfall. An initial set of flow recommendations can serve until further studies.
