The Government of Rwanda has received financing from the International Development
Association (IDA) toward the cost of the Commercialization and De-risking for
Agricultural Transformation (CDAT) Project and intends to apply part of the proceeds for
consulting service: Hiring individual consultant for dam review panel (Hydrologist expert)
The Terms of Reference (TOR) related to this assignment are attached to this request for
expressions of interest.
The Rwanda Agriculture and Animal Resources Development Board (RAB)/
Commercialization and De-risking for Agricultural Transformation (CDAT) Project now
invites eligible Individual Consultants (“Consultants”) to indicate their interest in
providing the Service. Interested Consultants should provide their CVs demonstrating that
they have the required qualifications and relevant experience to perform the Service.
The shortlisting criteria are:
The Hydrologist will have a minimum of a Master’s degree in Civil /Water Resources
Engineering (hydrology major) and 15 years demonstrated/proven working experience,
including a minimum of five years in hydrologic studies related to storage reservoirs.
Specifically, the expert will:
i) enhance the institution’s staff technical review capacity on hydrological matters;
ii) attend a joint workshop with other panelists and the client to present and discuss
hydrological procedures, methodology/standards to be used by consulting firms
contracted for the project;
iii) review feasibility studies and detailed designs in particular: (1) the hydrological
conditions with respect to availability of river flow/catchment run-off, stored in the
reservoir for multipurpose use, covering the demand; (2) the downstream condition
/hazards and required safety level /flood return period, (3) the design flood inflow
and reservoir attenuated outflow for determining the spillway capacity; (4) the soil
erosion level of the catchments, sediment, as well as sediment management plan;
(5) the reservoir operations; and (6) adequacy of live and dead storage considering
hydrological variability (including climate considerations), required water supply
reliability and sediment handing.
iv) To review upstream conditions, I regard to formation of landslide and handling
of floods caused by the collapse of such natural dams;
v) To review the reservoir factors of Dam stability, sedimentation, wave action,
clearing plans and their effect on dam stability;
vi) To review the flood Hydrology methodology and computations for determining
the project design flood hydrographs, reservoir routing and spillway sizing;
vii) To Review the design of spillway facilities including flow conditions, energy
dissipation or need for modeling.
viii) To review the inlet and outlet works, including its hydraulic designs,
capacity for emergency reservoir drawdown, sediment handling capability,
selective thermal releases, regulation range and other factors.
ix) To review the designs of diversion works schedule hydrology and risk factors
associated with diversion during construction and with the closure of diversion
works at initial reservoir filling.
x) To review the risk and hazard evaluations including need for Dam breach
analysis;
xi) To review the design for dam instrumentation and the program for collecting
evaluation and maintaining data to be obtained;
