Sedimentation in reservoirs - Tana river basin, Kenya. I – Base data taken from aerial surveys of Kindaruma and Kamburu, 1965

The Tana River is Kenya's major surface water resource, and siltation of the river has been the subject of a number of studies. However, there is still a large amount of work to be done if the factors influencing erosion, sediment transport and deposition are to be fully understood. One step towards reaching this understanding is achieved by making an analysis of the sediment accretion rates for two of the reservoirs which form part of the Seven Forks Project. This report presents an analysis of data taken from aerial surveys which were flown in 1965 for the design stages of Kindaruma and Kamburu reservoirs. This data will form the base against which all future reservoir surveys may be compared in order to obtain estimates of accretion rates. Following each hydrographic survey, a report will be published in the OD series giving details of the data collection techniques and reservoir volume analysis
