Hydraulics and Erosion Study for Stampede Reservoir
Stampede Dam and Reservoir is located on the Little Truckee River, approximately 34 miles west of Reno, Nevada. Severe waves were observed downstream of the spillway and outlet works channel causing significant erosion and undermining of the powerplant foundation. During the 1997 flood, discharges totaled 2750 ft3/s, including 2250 ft3/s from the outlet works and up to 500 ft3/s from the spillway. Three to four foot high transverse waves were observed downstream of the spillway and outlet works channel causing significant erosion and undermining of the powerplant foundation. Combined releases of 170 m3/s (6,000 ft3/s) from the spillway and outlet works are planned with new modifications to the dam. The purpose of this study was to evaluate erosion potential based on existing conditions and show possible erosion protection alternatives. This was accomplished with one and two dimensional hydraulic models as well as estimates for riprap sizing. Research was conducted to determine if any new methods could be found to evaluate erosion with strong wave conditions.
