This book presents the results ofresearch conducted between 2000 and 2004 on Lake Victoria (East Africa). The research examined the spatial spread of shoreline wetlands and found their distribution to be strongly influenced by the action of wind and waves. Evidence also pointed to a strong influence of wind-induced waves and currents on within-lake transport of surficial sediments. Paleolimnological reconstructions from bottom sediments confirmed earlier studiesdemonstrating the occurrence of eutrophication, and suggested that climate change was a co-driver of lake ecosystem change. It is argued that eutrophication could have led to destruction ofa number oflittoral plants speciesand has induced changes in fish populations. The study concludes by recommending the introduction of catchment management measures to reduce the export of nutrients to the lake.

Evidence also pointed to a strong influence of wind-induced waves and currents on within-lake transport of surficial sediments.

The highly dynamic nature of Lake Markermeer sediments must be due to the overall shallowness of the lake, together with its large surface area (dynamic ratio , . ); wind-induced waves and currents will impact most of the lake’s sediment bed. Indeed, near-bed currents can easily reach values 10 cm/s. Measurements of the thickness of the settled mud layer, as well as 137Cs dating, showed that long-term deposition only takes place in the deeper SE area of the lake.

Resuspension rates for Lake Markermeer were very high, viz. ca. 1,000 g/m(2)day as an annual average, leading to high suspended solids (SS) contents, due to the large lake area and its shallowness (high 'Dynamic Ratio'). and, consequently, near-bed currents would be much reduced.

This volume is taken from an ecological study of wetlands undertaken in northern Lake Victoria (East Africa) between 1993 and 1996 with the major aim of characterizing shallow interface habitats, and evaluating their importance for fish, in particular, for the Nile.
