A New Paradigm Of Modeling Watershed Water Quality
Accurate models to reliably predict sediment and chemical transport in watershed water systems enhance the ability of environmental scientists, engineers and decision makers to analyze the impact of contamination problems and to evaluate the efficacy of alternative remediation techniques and …

Modeling transport of agricultural chemicals in a dual porosity system resulting from macropores
… has been developed to simulate water flow and reactive chemical transport in both the soil matrix and the macropore region. Flow of water in both regions is governed by Richards' equation and chemical transport is based upon convective-dispersive mechanisms with linear kinetic sorption and …

Coupling source term, mineral reactivity and flow in radionuclide transport
… simulant groundwater than in deionised water. Reactive chemical transport simulations of waste glass dissolution and radionuclide release in a hypothetical near field were conducted over a time span of a million years with GoldSim. The results showed that enclosing the waste glass in a steel …

A Three-dimensional Bay/estuary Model To Simulate Water Quality Transport
… approach, all conceptualized biogeochemical processes are transformed into a reaction network. Through the decomposition of species governing equations via Gauss-Jordan column reduction of the reaction network, (1) redundant fast reactions and irrelevant kinetic reactions are removed …
