Modeling of groundwater contaminant transport with nonlinear sorption
A new algorithm based on the split-operator approach, henceforth referred to as the mass balance (MB) approach, was evaluated for modeling groundwater contaminant transport with nonlinear sorption isotherms. Particularly, ...
Determining flood return periods using ArcGIS-based hydraulic modeling and observation: A case study of Schoharie Creek, New York
In August 2011, Hurricane Irene swept through a large area in New York State, leaving thousands of people homeless and cities in pieces. The damages were widespread and devastating, whereas the precise scale of the floods ...
Non-uniform Sediment Transport and Time Scale Analysis in Unsteady and Non-equilibrium Conditions
While sediment transport in steady uniform flows has been studied extensively, significant amount of sediment movement occurs in unsteady flows. A nonhomogeneous discrete-time Markov chain model is proposed in this study ...
A physics-based emulator for the simulation of geophysical mass flows
Rare natural hazards such as large volcanic eruptions can cause loss of life and damage to property. With sufficient information, those charged with public safety may issue warnings of impending hazards, to mitigate the ...
Evaluation of a natural zeolite permeable treatment wall in the removal of strontium-90 from groundwater: Installation to long-term performance
An extensive set of experimental and modeling studies was completed to investigate the potential performance of a sorbing permeable treatment wall comprised of natural zeolite for the removal of strontium-90 from groundwater. ...
Simulation of granular flows over natural terrain using Godunov Smooth Particle Hydrodynamics
Smooth Particles Hydrodynamics (SPH) is a fully Lagrangian numerical method of obtaining approximate solutions to fluid dynamic problems. It was introduced by Lucy and Gingold & Monaghan independently. Since then it ...
