Abstract

The current velocities, tidal elevation, salinity and suspended sediment concentrations (TSSC) were measured in stations located within Malindi Bay in the Northern region of the Kenya coast. It is established that Malindi Bay receives a high terrigenous sediment load. The river freshwater supply into the bay is highly variable. Relatively low peak flows occurred in November during the North East Monsoon (NEM). The discharge of highly turbidity river water into the bay in April and May occurs in a period of high intensity South East Monsoon (SEM) winds that generate strong north flowing current that transports the river sediment plume northward. The mechanism of advection of the sediment plume north or south of the estuary is mainly thought to be due to the Ekman transport generated by the onshore monsoon winds. The high sediment discharge into Malindi Bay can be attributed to land use change in the Athi-Sabaki River Basin in addition to rapid population increase which has led to clearance of forests to open land for agriculture, livestock grazing and settlement
