Abstract:

In the past few years, there has been a growing recognition internationally, of a need to better understand hydrometeorologic, hydraulic, sedimentologic, geomorphic processes in gravel-, cobble-, and boulder-bed rivers, which most commonly are located in mountainous areas. Modeling river-system processes primarily is based on studies of lower gradient rivers (river gradient less than 0.002 m/m). Processes that occur in extremely turbulent, boulder- bed, higher gradient channels common to mountain watersheds are poorly understood. Thus, existing hydrologic and hydraulic models may produce unsatisfactory results for estimating precipitation, runoff, velocity, discharge, sediment and contaminant transport, and geomorphic changes.
