Natural Rivers, Urban Streams, and Working Waterways - Using Context to Inform Restoration
Presented by Andrew Earles, Ph.D., PE, CPESC, D.WRE & Natalie Phares, CFM, HIT
As a headwaters state, Colorado is blessed with many rivers and streams that are fed by the melting snow pack of the Rocky Mountains. In the mountains and foothills, there are Gold Medal trout waters that support a diverse ecological system; there are major rivers such as the South Platte and Colorado; and there are many ephemeral streams on the eastern plains. When conducting planning or design for improvements along river corridors in Colorado, it is important to understand the character of the stream and hydrologic, physical, and chemical factors that affect the natural processes supported by the stream corridor. When working in the stream, one must consider its context in the overall watershed. This presentation uses three case studies to illustrate these concepts.
