Floodflow characteristics of Current River at Arkansas state highway 328 near Reyno, Arkansas

Arkansas State Highway 328 in Randolph County crosses Current River about 1.5 mi northwest of Reyno, Arkansas. A main channel bridge with a relief bridge on each side, five culverts, and a bridge on the west side of the valley were the existing flow structures prior to a December 1982 flood. After the December 1982 flood, 34 additional culverts were installed along the highway. The flood of December 3, 1982, which had a computed peak discharge of 85,300 cu ft/sec and a recurrence interval of about 8 years, caused considerable damage to the highway being reconstructed. The flood of April 1985, which had a discharge of 48,000 cu ft/sec and a recurrence interval of about 2 years, also caused damage to fill areas of the reconstructed highway. A hydraulic analysis was conducted for the 5-, 10-, 25-, 50- and 100-year flood and the floods of December 1982 and April 1985 to determine the river stages before and after Highway 328 was reconstructed. Results of the study indicate that the water surface along the upstream water surface elevations less than 0.1 ft. (USGS)

Mathematical model for simulating discharges on the Sabine River between Tatum and Ruliff, Texas

A mathematical model for simulating discharges on the Sabine River between Tatum and Ruliff, TX., was developed to evaluate the effects of release schedules on discharges from the Toledo Bend Reservoir compared to discharges under natural conditions. Using the discharge at Tatum, TX., the rainfall over the basin, and the discharge release schedule for the reservoir, discharge hydrographs for the natural and reservoir-controlled conditions can be computed.

Elevations and discharges produced by a simulated flood wave on the lower Sabine River, Louisiana and Texas, caused by a theoretical dam failure

The Toledo Bend Reservoir is located on the lower Sabine River between Louisiana and Texas. The objective of this study was to calculate the flood wave that would result from the theoretical failure of 25 percent of Toledo Bend Dam and route the wave downstream to Orange, Tex. Computations assumed failure (1) at the peak of the 100-year flood when discharge of the Sabine River would be 102,000 cubic feet per second and (2) when the average discharge would be 10,000 cubic feet per second. Two techniques were used in the dam-break model. The method of characteristics was used to propagate the shock wave after the dam fails. The linear implicit finite-difference solution was used to route the flood wave after the shock wave has dissipated. The magnitude of the flood was determined for sites near Burkeville, Bon Wier, Ruliff, and Orange, Tex., along the lower Sabine River. For these sites, respectively, the following peak elevations were calculated: 119, 82, 31, and 13 feet for the 100-year flood and 110, 75, 27, and 9 feet for the average discharge.

Study to determine discharge at 50-percent flow duration and ordinary high water for streams in Louisiana

Techniques are presented for estimating the discharge at 50-percent duration and "ordinary high water" on ungaged streams in Louisiana that have drainage areas of less than 3,000 square miles. Discharge data from 91 gaging stations were used in developing the techniques. The discharge at 50-percent duration can be estimated if the drainage-area size and mean annual precipitation are known. The "ordinary high water" can be estimated if the drainage-area size, mean annual precipitation, channel cross section, channel slope, and Manning's roughness value are known.
