Preliminary Laboratory Investigation of Section 32 Hard Point.

Abstract

This report describes a series of preliminary tests of a short duration model study conducted on erosion control structures at the Mead Hydraulic Laboratory. The specific erosion control structures investigated were hard points. Hard points are two-part structures consisting of a spur and a root. The spur is placed directly on the channel bank to stop streamflow erosion at that point. The root provides a tie from the spur into the bank to prevent the structure from being outflanked by bank erosion. This is the eighth report prepared for model studies at the Mead Hydraulic Laboratory. Demonstration Projects are to be constructed to develop economical erosion-control structures which do not have a significant adverse ecological impact and which will either retain or improve the existing riverine fish and wildlife habitat. These model tests were preliminary to a more extensive study on hard points and were conducted to determine the effect of a single hard point structure on the bank and stream bed utilizing an L-Head or dike extension with varying orientations of the root section. One test was also conducted to determine the effect of a pair of hard point structures.
