Analytical Determination of Pollutant Wash-Off Parameters
Publisher: American Society of Civil Engineers
Abstract: The wash-off algorithm in the Storm Water Management Model has been widely used to simulate the wash off of sediment and pollutants from impervious areas. This algorithm indicates an exponential relationship between pollutant ...
Closure to “Stable Width and Depth of Gravel‐Bed Rivers with Cohesive Banks” by Robert G. Millar
Publisher: American Society of Civil Engineers
Simulating Bed-Load Transport in a Complex Gravel-Bed River
Publisher: American Society of Civil Engineers
Abstract: An existing two-dimensional mobile-bed hydrodynamic model has been modified to simulate bed-load transport in a complex gravel-bed river. We investigated the sensitivity of predicted bed load to control parameters, and ...
Discussion of “Estimation of Gravel‐Bed River Flow Resistance” by Colin D. Rennie and Robert G. Millar
Publisher: American Society of Civil Engineers
Deconvolution Technique to Separate Signal from Noise in Gravel Bedload Velocity Data
Publisher: American Society of Civil Engineers
Abstract: A deconvolution procedure is presented to estimate the probability density function of bedload transport velocity from noisy stationary data collected using the bottom tracking feature of acoustic Doppler current profilers ...
Effect of Bank Stability on Geometry of Gravel Rivers
Publisher: American Society of Civil Engineers
Abstract: A bank‐stability analysis is incorporated into an analytical procedure for modeling the hydraulic geometry of an alluvial gravel‐bed channel. The new analysis includes a procedure that calculates the mean bed and bank shear ...
Stability of Ballasted Woody Debris Habitat Structures
Publisher: American Society of Civil Engineers
Abstract: An important component of stream restoration in the Pacific Northwest is the reintroduction of large woody debris (LWD) and construction of LWD habitat structures in degraded systems. A significant problem faced by engineers ...
Stable Width and Depth of Gravel-Bed Rivers with Cohesive Banks
Publisher: American Society of Civil Engineers
Abstract: An analytical model is developed to determine the influence of the bank stability on the stable width and depth of alluvial gravel-bed rivers with cohesive banks. The formulation of the model is based on the assumption ...
Measurement of Bed Load Velocity using an Acoustic Doppler Current Profiler
Publisher: American Society of Civil Engineers
Abstract: A new technique has been developed to measure the apparent velocity of bed load
Modeling Bed Changes in Meandering Rivers Using Triangular Finite Elements
Publisher: American Society of Civil Engineers
Abstract: A two-dimensional depth-averaged model was used for the simulation of scour and deposition in sand-bed meandering channels with fixed banks. The model employs unstructured meshes based on triangular elements and incorporates ...
