Callide Valley Flood Mitigation Study Hydrologic and Hydraulic Modelling
The work required under this request has been broken down into parts (see section 1.6 Requirements) that address the following:
development of a methodology for the selection of design annual exceedance probability (AEP) rainfall depths, temporal patterns and intensities for a range of AEP events;
the subsequent hydrological modelling of those events for the catchment “base case” (existing situation) and selected historic events plus a number of flood mitigation “scenarios” to determine inflows to a Callide Valley hydraulic model;
Estimation of the AEPs of the Callide Dam crest floods (DCF) for the base case and alternate operational scenarios; and
Callide Valley hydraulic model runs to test the flood mitigation benefits of scenarios (including variations to dam operations) selected by the Project Work Group (PWG).
The development of the calibrated base case Callide Valley catchment hydrological models and the Callide Valley hydraulic model are not part of this work request and will be / have been developed by KBR under a separate but related project for Banana Shire Council
