Guidelines for the Use of Stream Reconnaissance Record Sheets in the Field
Abstract
The first objective of this study was to evaluate the potential for practical application of existing bank erosion assessment sheets as an aid to field identification of (a) the state of vertical and lateral channel stability; (b) the relation of local bank retreat to channel instability; (c) the engineering and morphological characteristics of the banks; (d) the dominant erosive forces and processes; (e) the state of bank stability and major failure mechanisms; (f) the severity and extent of bank erosion in the reach; and (g) the input parameters necessary for modeling bank retreat. The second objective was to undertake field testing of the bank erosion assessment sheets and guidelines in a wide variety of river environments to identify areas of weakness or mechanisms and bank erosion scenarios not covered by them. The third objective was to further develop the sheets and guidelines to produce an assessment system suitable for routine use nationwide by nonexpert personnel. The bank erosion assessment sheets developed as a result of this study, referred to as stream reconnaissance record sheets, and the guidelines developed for their use present a system for the orderly and disciplined collection and recording of comprehensive qualitative and semiquantitative data on streams and rivers. The development of the stream reconnaissance record sheets from this study was based on real-world applications by practicing engineers concerned with actual problems. As such they should be of immediate value to the U.S. Army Corps of Engineers in fulfilling its mission.
