Notes

Summary:
The Florida International Research iWASH Initiative Limited commissioned this study to assess and develop rating curves in the Ruvu River Sub-basin. The work concentrated at the six key strategic stations within the Sub-basin that include: Ngerengere at Konga 1HA9A, Ngerengere at Mgude, Ruvu at Morogoro - Dar es Salaam Road 1H8, Ruvu at Kibungo 1H5, Mgeta at Mgeta 1HB2 and Mgeta at Duthumi 1HB1411. Specifically, the work reviews the existing rating curves for the existing stations on the Ruvu, update and validate cross-sections at the six strategic stations, conduct flow measurements, conduct analysis and produce new rating equations for the six strategic stations. The work utilizes the historical stage-discharge measurements and the new measurements collected during the period November 2012 to May 2013. Results indicate that most of the stations were established in the early 1950s and discharge measurement in these stations continued until late 1980s, with no measurements between early 1990s and mid 2000s. Review of the rating relationships indicates validity of historical data up to the early 1980s for most of the stations, but cannot be used to transform gauge heights (water levels) without modification. Assessment of physical characteristics at the six key stations revealed fair hydraulic controls. Nevertheless, special attention will be required to attend some observed threats at the channel hydraulic sections.
