A mobile dive unit was deployed by road to Lilongwe Malawi to survey
the Kamuzu Dam, in order to evaluate the construction techniques used
as well as possible maintenance and repair methods.
A depth survey and visual inspection of the scour area and toe was
taken in order to determine the extent of erosion.
The pump house gallery had been flooded and an underwater survey of
the valve chamber was required.
The upstream wall was surveyed for cracking, silting and condition
of trash racks.
Divers remained in constant communication with the surveyor/supervisor
on the surface, relaying depths and information on the physical condition
of the structure.
Information acquired by this survey was posted in CAD diagrams.
