HYDROGEOCHEM - hydrologic transport and geochemical reaction model

HYDROGEOCHEM Categories: hydrogeochemical models, reactive transport, geochemical models, solute transport models - saturated zone, solute transport models - unsaturated zone


HYDROGEOCHEM is a coupled model of hydrologic transport and geochemical reaction in saturated-unsaturated media. It is designed to simulate transient and/or steady-state transport of Na, aqueous components and transient and/or steady-state mass balance of Ns adsorbent components and ion-exchange sites. Along the transport path, HYDROGEOCHEM computes the species distribution of N component species, Mx complexed species, My adsorbed species. Mz ion-exchanged species, and Mp potentially precipitated species. HYDROGEOCHEM is the only commercially-available model for the simulation of reactive multispecies-multicomponent chemical transport through saturated-unsaturated media. It is not a path model; it is a true transport model coupled with homogeneous and heterogeneous geochemical reactions.
