Truckee River Flood-Control Project, Truckee Meadows (Reno-Sparks Metropolitan Area), Nevada; Hydraulic Model Investigation.

摘要

Tests were conducted on a 1:30-scale model of the Truckee River, Nevada, to determine the adequacy of channel improvements proposed by the sponsor. The model reproduced approximately 3,200 ft of the Truckee River running through downtown Reno, NV. Tests conducted with the proposed design channel with the design flow (100-year frequency event, 18,500 cfs) indicated areas within the modeled reach that needed modifications to improve flow conditions. These modifications to the sponsor-proposed improvements included replacing the paved slopes at the north abutment of the North Arlington Street Bridge with a vertical wall extending down to the channel invert, increasing the floodwall heights in the vicinity of the South Arlington Street Bridge, moving the channel invert chute upstream approximately 44 ft, and using two bridge piers at the Sierra Street crossing rather than one. The recommended design resulted in acceptable flow conditions throughout the modeled reach with the design discharge....
