Abstract
St. Anthony Falls Hydraulic Laboratory was contracted by the West
Virginia office of the U. S. Soil Conservation Service to construct and
evaluate a physical scale hydraulic model of Howard Creek as it flows
through White Sulphur Springs, West Virginia. The reach in question
extends from the Garden Street bridge on the upstream end to just past the
Greenbrier Avenue bridge on the downstream end. This reach is subject to
periodic flooding and has several complicating features. The complications
include the confluence of Dry Creek just upstream of Big Draft Road near
midreach, a substantial change in slope from approximately 0.00405 to
0.00151 near this confluence, and a corresponding change in sediment size
distribution progressing downstream. In addition, the entire reach is closely
surrounded by private residences as well as some commercial and public
buildings.
The Soil Conservation Service is proposing channel modifications
designed to reduce flooding in this reach. This study primarily evaluates
performance of the proposed design with regard to sediment scour and
deposition, and bank protection performance under conditions of both
sediment deficient and sediment surplus, for each of 2-year, 10-year, and
100-year floods. (Please note that throughout the report the words starved
or deficient are used interchangeably.)
This report covers the model design, model construction, the choice and
sizing of suitable model sediment and riprap, calibration of the model, testing,
modifications, and conclusions.
