Survey Form B-3 Problem Statement Vegetation is the most natural method for protecting streambanks, and it provides ecosystem services in the form of habitat, water quality and aesthetic benefits. Stream bank protection measures that incorporate vegetation are referred to as biotechnical or bioengineered measures. However, there is a reluctance on the part of designers to employ biotechnical measures due to a lack of quantitative guidance. The objectives of NCHRP Project 24-39 are to produce guidelines for appropriate selection, design, installation, and maintenance of environmentally sensitive stream bank stabilization and protection measures. Your response Please complete the forms on the following pages for each of the major physiographic provinces in which you have streambank protection projects featuring biotechnical measures. This form is for physiographic province number _______.
