dc.description.abstractStage-discharge relations for two artificial controls were determined in a model study conducted at Colorado State University. The controls are used to measure the discharge at two gaging stations (Cibecue Ridge No. 1 and Cibecue Ridge No. 2), that form a part of an intensive hydrologic investigation of the semi-arid environment of Central Arizona. The gaging stations are located in a remote area where the runoff is infrequent and of brief duration. The model studies were conducted because it was virtually impossible to calibrate the controls in the field. In addition to determining the stage-discharge relation, modifications in the controls are proposed to improve the discharge records for the two stations. A hydraulic jump occurs in the present controls at the section where the stage is measured. The hydraulic jump keeps the controls clear of the large sediment discharge of the streams, but causes large fluctuations of the water surface in the stilling wells. The modified controls eliminate the hydraulic jump, make extensive use of the construction that presently exists, will pass the sediment discharge of the streams, and have a fairly sensitive stage-discharge relation. The recorded elevation of the water surf ace in the stilling well lags the actual elevation of the stream because the connection between the control and the stilling well is too small in relation to the size of the stilling well. The lag can be decreased by replacing the present stilling well with a tube 14 to 20 inches in diameter.
