Model Study of Sluices for Fall River Dam, Fall River, Kansas
Abstract
The model study of sluices for Fall River Dam was conducted to determine the hydraulic performance of alternate sluice designs discharging into a stilling basin developed from consideration of spillway flow. The alternate sluice designs consisted of a sluice with its exit invert at stilling basin elevation and a sluice with its exit invert 13 ft above stilling basin elevation and containing a tetrahedral deflector. Five variations of the latter design were studied, The stilling basin consisted of a horizontal floor 105ft long, a stepped end sill 7 ft high, and two rows of 8-ft-high baffles. It was determined from the model study that performance of the deflector-type sluice was the more favorable. Also, it was found that special treatment of the flared sidewalls of the deflector-type outlet portal was required to obtain satisfactory pressure conditions thereon, The sluice design designated type 6 in this report, details of which are shown on plate 37, is recommended for installation in the prototype.
