River Rating Curves and Equations, Kwale County, Kenya (NERC grant NE/M008894/1)

The data sets contain the rating curves and equations, approved stage (H) discharge (Q) data for the purposed of building river rating information for three hydrometric stations: 3KD06 and KISCOL weir on Mukurumudzi River and Eshu Bridge on Ramisi River, in Kwale.

Statement: 1) River flow measurements were undertaken using a Velocity Current Meter (Valeport) and an Acoustic Doppler Current Profiler (ADCP) during low, medium and high flow conditions at the three sites. 2) A Hydraulic Engineering Center-River Analysis System (HEC-RAS) model was set up for each site to simulate river surface water profiles under different flow conditions. The HEC-RAS model input included cross section and longitudinal surveys of the reaches. Engineering drawings for hydraulic structures and flow control sections were used to define model geometry. The model was calibrated and validated against measured stage-discharge data under unsteady state condition until the best agreement between measured and simulated was achieved. River rating curves and H-Q values were extracted from the calibrated and validated model to provide an accurate representation of river flow conditions.
