Developing a Standard of Practice by Organizing Goals/Objectives,Multidisciplinary Investigations and Design Criteria into a Process for Design: An Example

摘要

Designing and implementing stream habitat improvement techniques is a current field ofengineering/landscape architecture that has no generally agreed upon standards of practice.Therefore, many different approaches are used, some analytical and others experienced based.This variation in approach often leads to confusion within professions and prevents adequatereview of both completed and proposed designs and projects. This is further complicated asmany practitioners believe that design is as much art as science. Professional practice standardsdefine decision-making procedures/methods used by practitioners and establish the basis forrational design development.This paper highlights a process whereby the development of goals and objectives, investigationsof specialty disciplines (hydrology, geomorphology, hydraulics, fisheries, etc.) followed by thedevelopment of design criteria prioritized by goals/objectives, provide a basis for a standard ofpractice. A stream improvement example serves to illustrate key points.
