<br />Cave Creek above Deer Valley Road <br /> <br />Reach location: <br /> <br />Latitude 33041'13", longitude 112003'32". Reach ends about 1,000 ft above Deer <br />Valley Road. <br /> <br />d50 = 91 mm (030 ft). <br /> <br />Bed-material size: <br />Channel descrintion: <br /> <br />The channel is straight and uniform throughout the reach, The cross sections are <br />trapezoidal in shape, and vegetation of moderate spatial density is along the banks, <br />Bed material found in the reach is mostly small, to medium-sized cobbles. The <br />stream is ephemeral, and flow is regulated by Cave Buttes Dam. <br /> <br />The bank vegetation probably had a discernible effect on total flow retardance for <br />the two larger flows. This bank vegetation was little affected by flows. The <br />suspended, sediment concentration was 228 mg/L for the flow on January 9, 1995, <br />and is assumed to be indicative of suspended-sediment concentrations for all three <br />flows. The suspended sediment was regarded as wash load and was considered to <br />have negligible effects on n values, <br /> <br />Remarks: <br /> <br />Table 7, Flow data and computed roughness coefficients, Cave Creek above Deer Valley Road <br /> <br />Date of flow Discharge, in cubic feet per second Roughness coefficient Rating <br />01-06-95 297 0,033 Estimate <br />01-D9-95 t93 ,033 Good <br />01-10-95 39 ,034 Good <br /> <br />Table 8.
