FLUVIAL GEOMORPHOLOGY & NATURAL CHANNEL DESIGN
Streams are open thermodynamic systems in which numerous parameters interact to produce a near equilibrium condition. These parameters, such as channel morphology, slope, discharge, and sediment load, are constantly changing in nature. At PEIL, we evaluate each of these interactions to determine process-response systems in order to develop remediation strategies which are appropriate for each individual situation and can provide for a greater probability of success.

The fundamental goal of fluvial ecosystem assessment, restoration and monitoring is the maintenance of a target system's structure and function both locally and within its broader landscape or watershed context. To measure the degree of success in achieving such goals; physical, chemical, and biological evaluation and data are necessary to verify that an ecosystem is performing as it should. In our fluvial geomorphological studies we verify the performance of a study creek in the overall watershed context. To achieve long-term success, fluvial ecosystem evaluation should, where possible, address the causes and not just the symptoms of potential ecosystem disturbance. Sometimes these causes are obvious, and sometimes they are far removed in time and space from the ecological damage.
