Preliminary Laboratory Investigation of Section 32 Hard Point Conducted at Mead Hydraulic Laboratory, Mead, Nebraska
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 under the authority of P.L. 93-251, Section 32. 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. Through P.L. 93-251, Section 32 authority, 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.
