| The catchment of Winam Gulf in Kenya supports a population of 4.5 million inhabitants. Much of the population practices subsistence agriculture in the catchment that has led to high rates of sediment erosion and ultimately highly turbid rivers. Hence, every year during the two equatorial wet seasons, large quantities of catchment sediments are deposited into Winam Gulf. In Apr.-May 2005 an intensive field investigation was undertaken to determine the exchange dynamics between the northeastern offshore waters of Lake Victoria and Winam Gulf through Rusinga Channel. One of the outcomes of this scientific study was the validation of ELCOM (Estuary, Lake and Coastal Ocean Model), a three-dimensional (3D) hydrodynamics model, over Rusinga Channel and Winam... |

| During April, May and August 2005 intensive field investigations were undertaken to characterize the physical limnology of Winam Gulf and Rusinga Channel regions of Lake Victoria in Kenya. Both the field data and numerical simulations with the three-dimensional (3D) hydrodynamics model, ELCOM (Estuary, Lake and Coastal Ocean Model), during these two field studies led to two major conclusions. First, though water currents in Rusinga Channel can be quite large (ca. 10-50 cm s-1), exchange through the channel is low because the tidal-like oscillations result in low net transport over a 24 hour period. Second, Winam Gulf can be segmented into four regions, two of which have relatively low flushing rates as compared to time scales of biogeochemical processing.... |
