The report presents the results of tests conducted on a 170-scale section model reproducing one-half of the spillway for Amistad Dam, a combination concrete gravity and earth embankment structure rising 253 ft above the bed of the Rio Grande. The spillway consists of an ogee crest controlled by 16 tainter gates, 50 ft wide and 54 ft high, and a hydraulic jump type stilling basin. The spillway will be flanked on each side by a powerhouse. Discharge characteristics of the spillway, hydrostatic pressures on the ogee weir crest, lateral pressures on the gate piers, performance of both single- and double-stage stilling basins at various elevations, and the height and length of both spray and stilling basin training walls were investigated. The theoretical spillway rating curve and the expected hydrostatic pressures on the weir crest were in close agreement with those determined with the model. Author
