Prototype Scale Evaluation of Non-Newtonian Algorithms in HEC-RAS: Mud and Debris Flow Case Studies of Santa Barbara and Brumadinho
Autor: Stanford Gibson, Leonardo Zandonadi Moura, Cameron Ackerman, Nikolas Ortman, Renato Amorim, Ian Floyd, Moosub Eom, Calvin Creech, Alejandro Sánchez
Publikováno v: Geosciences, Vol 12, Iss 3, p 134 (2022)
The Santa Barbara post-wildfire debris flows and the Brumadinho tailing-dam failure were two of the most catastrophic flood events of the late 2010s. Both these events carried so much solid-phase material, that classic, clear-water, flood risk approa

Optimization of reach-scale gravel nourishment on the Green River below Howard Hanson Dam, King County, Washington
Autor: Zachary Corum, Ethan Cheng, Stanford Gibson, Travis Dahl
The US Army Corps of Engineers, Seattle District, nourishes gravel downstream of Howard Hanson Dam (HHD) on the Green River in Washington State. The study team developed numerical models to support the ongoing salmonid habitat improvement mission dow

Discharging Sediment Downstream: Case Studies in Cost Effective, Environmentally Acceptable Reservoir Sediment Management in the United States
Autor: John Shelley, Stanford Gibson, Paul M. Boyd, Rollin H. Hotchkiss
Publikováno v: Journal of Water Resources Planning and Management. 148
Sediment accumulation in reservoirs across the world diminishes reservoir benefits, increases maintenance costs, and damages the environment. United States regulatory policy requires State ...

Two pool-to-pool spacing periods on large sand-bed rivers: Mega-pools on the Madeira and Mississippi
Autor: Renato Amorim, Calvin Creech, M. Koohafkan, Stanford Gibson, Travis A. Dahl, M. Dircksen, A. L. N. A. Osório
Publikováno v: Geomorphology. 328:196-210
The Madeira River thalweg includes two pool-to-pool spacing periods. First, standard pool-crossing sequences form 6 to 8 m deep pools. These pool-crossing sequences recur approximately every six channel widths (9.7 km or 6.8 W), on average. However,

Approaches for assessing riverine scour
Autor: Stanford Gibson, Chris Haring, David May, Brian Alberto, Michael Haring, Jang Hyuk Pak, Adam Howard
Calculating scour potential in a stream or river is as much a geomorphological art as it is an exact science. The complexity of stream hydraulics and heterogeneity of river-bed materials makes scour predictions in natural channels uncertain. Uncertai

A Modular, Non-Newtonian, Model, Library Framework (DebrisLib) for Post-Wildfire Flood Risk Management
Autor: Alejandro Sanchez, Ian Floyd, Stanford Gibson, Gaurav Savant
Wildfires increase flow and sediment load through removal of vegetation, alteration of soils, decreasing infiltration, and production of ash commonly generating a wide variety of geophysical flows (i.e., hyperconcentrated flows, mudflows, debris flow

Post-Wildfire Numerical Modeling for Flood Risk Management
Autor: Gaurav Savant, Alejandro Sanchez, Stanford Gibson, Ian Floyd, Ronald E. Heath
The number and intensity of large wildfires in is a growing concern in the United States. Over the past decade, the National Interagency Fire Centre (NSTC, 2015) reported increases of large fires in every western state in the arid and semi-arid weste

Numerical Dispersion of Bed Load in a 1D Model Mimics Physical Flume Results
Autor: Travis Dahl, Stanford Gibson, Ian Floyd, Alejandro Sanchez
The longitudinal dispersion of bed load particles as they move downstream in a river is relevant both to cases of polluted sediment and pulses of sediment released during reservoir flushing events or dam removals. To quantify the rate of bed-load dis

1D and 2D Debris Flow Modeling with HEC-RAS
Autor: Alejandro Sanchez, Ian Floyd, Stanford Gibson, Cameron Ackerman
The Hydrologic Engineering Center River Analysis System (HEC-RAS) is a free software developed by the United States Army Corps of Engineers for simulating hydraulics, sediment transport, and water quality. We present on the recent and ongoing develop
