Abstract: A momentum-impulse model that accounts for the critical impulse of a particle bridge that is balanced with a fluid pulse resulting from turbulent pumping is presented and applied for predicting the clogging depth of fine ...

Abstract: Sediment fingerprinting has been developed by researchers over the past three decades for watershed sediment transport research. Sediment fingerprinting is a method to allocate sediment nonpoint source pollutants in a ...

Abstract: This research estimates sediment yield contributed from surface mining soils, stream banks, and forest soils using sediment fingerprinting with isotope tracers coupled with soil erosion and sediment yield modeling in mixed ...

Abstract: An understanding of the clogging of fine sediments within gravel substrates is advanced through use of dimensional analysis and macroanalysis of previously conducted clogging experiments in hydraulic flumes. Dimensional ...

Abstract: Similarity analysis is performed for hydraulically rough open channel flow over a gravel bed to provide mixed outer scaling of the mean-velocity profile. The analysis is based on equilibrium turbulent boundary-layer theory ...

Abstract: Diffuse optical sensors estimate attenuation of natural light (solar irradiance) by measuring its vertical distribution in the water column, and the sensors are useful for estimating both suspended sediment concentration ...

Abstract: This paper is motivated by the need to develop low cost, wireless velocity sensors for hydraulic research and application in streams. A velocity bend sensor (VBS) is a flexible plastic polyimide substrate sheet with an ...

Abstract: A light attenuation sensor system (LASS) for measurements in waters is described in this paper. The LASS records irradiance at multiple levels in the water column to provide a measure of the diffuse light attenuation ...
