REMR Management System - Navigation Structures: A Simple Condition and Performance Rating Procedure for Riverine Stone Training Dikes and Revetments

摘要

This report describes a simple algorithm that provides a quantitative description of the condition of riverine stone navigation training dikes and revetment. The quantitative description, called a condition index (CI), is incorporated into a REMR Management System for stone navigation training dikes and revetment. The CI is an indicator of a structure's condition and, to some extent, its functionality. The CI is obtained from an algorithm that uses field inspection data as input and is designed so that it provides consistent, repeatable, uniform results. The fundamental goals of the REMR Management System are to establish Corps-wide inspection uniformity and to establish common definitions of condition so that more effective communications concerning condition can be made. REMR Management Systems use uniform condition inspection techniques that emphasize visual, inexpensive, and efficient methods of data gathering. The Corps oversees the maintenance and repair of thousands of river bank stabilization structures and maintains an inventory of nearly 11,000 riverine training dike structures. This report addresses the condition assessments of existing stone dikes and stone dikes that will be constructed in the future.
