<br />suitable design criteria developed. Therefore, the classification method takes various combinations of <br />mobility and stream power and establishes a class identification, This identification is associated with <br />stream pattern (meandering or braided) and type of bed matl~rial sE:diment transport, <br /> <br />PROJECT SCREENING <br /> <br />Figure 2 illustrates the potential domain for project planning and execution. When few resources are <br />available (to the right on the horizontal axis), knowledge of river behavior can produce some success but <br />success or failure is still largely the result of natural processes and events, When ample resources are <br />available (to the left on the horizontal axis), the river system is oftl~n manipulated or influ<~nced by man, <br /> <br />For many communities, resources combined with a good knowledge (to the top of the vertical axis) of the <br />physical processes within the river system provides a prudtmt solution, This approach is lower in total <br />constructed cost and can be as successful as projects that are much more costly, Funding of projects in <br />this range allows for more projects over time, fulfilling a broader need, <br /> <br />Of course, communities may gamble with limited resources using only limited knowledge of the river <br />environment. Depending on the inherent risk within the river form, chances for success may range from <br />fair to poor. On average, projects of this type will fail far more often compared to similarly funded <br />projects that are based on more knowledge of the river environment. <br /> <br />COMMUNICATION <br /> <br />Because rivers are complex, the cost and technical expertise requir~.d to complete a restoration will vary, <br />Over time, it will be of interest to funding agencies and participating communities to accumulate design <br />knowledge that is well suited to particular types of stream channels and poorly suited to other types, In <br />particular, information on the cost of planning, design, and construction of projects will aiel in budgeting <br />for future years, <br /> <br />Technical information on structural and non-structural approaches, design tools, construction stanelards, <br />methods of data collection, permit requirements, revegetation metllOds, and much more information is <br />needed. The associated stream classincation is a relatively easy means of organizing this information, <br /> <br />With the aid of computer systems for Geographical Information (GIS) and Internet communication, it is <br />expected that much of this information can be shared with communities, many of whom would not <br />otherwise have such information, Stream classification can become the first step for a wmmunity to <br />undertake the data collection and analysis to plan for stre.am rehabilitation projects.
