directly linked to conduits and open channels in the model hydraulics component. Once model stability for ' extreme events is assured, Consultant shall run the modei for the full suite of design storms with detailed representation of system tail water conditions. Develop ZD Existing Condition Floodplain Model: The interior model will include the infrastructure identified in Table 1 below: Table Z lnterior Modellnfrastructcrre Included � Price O.q 1.5 14 Veterens 0.0 1.5 12 ' Bradfard �.0 2.0 26 t7ddstadt 0.0 1.4 14 Maple and Kmar[ 0.3 1.5 14 Redwood Creek 0.8 0.3 2 TOTAI.: 1.1 8.2 82 Deve{op Tidal/Boundary Condition Model Component: Consultant shall develop open channei hydraulic models for reaches of K-Mart, Redwood Creek, and the channel along 101 and 81air Island from the Bay to the end points. Develop Tidai Boundary Conditions. FEMA is developing a new regional South Bay 2D model. DHf has been brought on the team so that the most recent version of this model can be utilized for development of the tidal still water elevations. Consultant shall use the most recent version of the South Bay 2D model to develop tidal still water elevations. Ca(ibration:Consultant shall place a recording gage at the following locations: 1. In interior pipes upstream of either the Maple or Bradford Pump Station 2. In Redwood Creek underground pipe upstream of Bradford Pump Station Consultant shall use Data from the gages in the first significant storm of the season to calibrate the hydrologic parameters. The first gage will help calibrate interior system models, and the second will be used to calibrate the Redwood Creek hydrology in the tidal/boundary condition model. Doppler RADAR data for the selected storm will be collected and used as inpwt to the calibration model. Consultant shall collect and compile the Doppler RADAR and gage-adjust with a resolution of 1 square kilometer, at 5 minute increments. The gage adjusting is done with local on the ground precipitation data to calibrate the RADAR depths to actual depths. Deliverable: Calibrated Interior H&H Model of Five Watersheds, Linked to Calibrated Boundary Condition Model. Schedule: to be completed by July 31,2014.
