Hydrological advice for Chamavita water schemes

On request of Aqua for All a field visit was carried out to a number of water schemes constructed by Chamavita in the Lushoto district, Usambara Mountains, Tanzania.
In this area a measuring campaign was set up to get insight in the behavior of the Lukozi and Kwemakame water schemes.
The aims of the visit were to see the progress of the measuring campaign, to give technical advice on the measuring campaign and the water schemes, and to assist with any further problems or questions on the water schemes.

Dam safety for Chamavita waterscheme – Hambalawei dam

The Hambalawei Dam currently retains water for drinking water purposes. Chamavita plans to heighten the dam, to store more water. With a larger dam construction, larger forces in the construction and in the soil will occur. In this note the safety of the larger dam is explored. There are several failure mechanisms that can cause dam failure. Here we will investigate the safety against rotation and shear, and piping. These are recognised as the main threads to failure.
