dc.description.abstractThe sediment accumulation in rivers and the sediment deposition in the reservoirs is currently influencing a remarkableimpact on the land and water resources in Kenya. Inappropriate land use and wastes disposal in the watershed are anthropogenicactivities resulting in the contamination of the water body in Lake Nakuru. This research study focusses in the lake sedimentationassessment and examination of sediments impacts on the storage loss in Lake Nakuru. This was achieved by establishing theengineering concepts using Bathymetric Surveying System (BSS) comprises navigation twin boats system (Dual-Jon-Boats), built-in Global Positioning System (GPS) for collecting spatial data, acoustic multi-frequency system with higher frequency of 200 kHzfor determination of surface of the sediments and the lower frequency of 12 kHz for determination of deposited sediments layer topre-impoundment levels of the Lake. The software like Depthpic 5.0.2, Surfer 15.5 and ArcGIS 10.3 were used for mapping,gridding and morphometric analysis. The study results show that the lake depth increasing from the shoreline to the middle patchof the lake with the maximal depth of 6.2 meters and the water storage volume of 264,699,344.54 m 3 . The sediment depositionwith the layer thickness varies from 0 m up to 0.7 m (maximum) and the total sediment storage capacity of 24,191,688.67 m 3 , thisimplies that the sediment storage in the lake occupies 8.37 % of its actual storage capacity. The water and sediment storage statuscater to accurate information to the water resources managers in making decisions to the resources’ management in or around thelake.
