Abstract: Conventional multilayered riprap and filter protections around bridge piers can be substituted by one thick single layer of riprap. Because of this simpler construction, field installations are less likely to be defective. ...

Abstract: Critical bed shear stresses for grains in a mixed-size bed are known to depend on the ratio between the size of dislocated grains and an average grain size for the bed. However, laboratory experiments with sediments ...

Abstract: An expression is derived for the critical shear stress of surface flow on a noncohesive soil slope subjected to seepage‐induced mass wasting, i.e., erosion caused by a successive mobilization of flake aggregates of surficial ...

Abstract: The management of water flow using reservoirs for the purpose of hydropower production can have significant impacts on solute transport. Reducing the phosphorous load to downstream areas can be of great importance for ...

Abstract: Contaminant migration in streaming waters is characterized by a large number of physical and biochemical transfer mechanisms that often exhibit marked spatial and temporal variabilities. To quantify the mass transport and ...

Abstract: A new modeling framework for internal erosion in heterogeneous stratified soils is developed by combining existing methods used to study sediment transport in canals, filtration phenomena, and stochastic processes. The ...

Abstract: This paper analyzes the transport of sorbing solutes by extending the advective storage path model developed for longitudinal transport of inert solutes in streams coupled with flow-induced uptake in the hyporheic zone. ...

Abstract: The transport and retention of a sorbing solute in streams are affected by the transversal uptake in various hyporheic zones, each characterized by its individual turnover time. The uptake is included in a one-dimensional ...
