Watershed Hydrology and Transport Model

MODFLOW-Watershed Hydrology and Transport:

A modeling framework designed to simulate the flow and transport processes of a watershed as a holistic system.

Features:

Fully-coupled 3-dimensional surface-subsurface flow simulation using an enhanced version of MODFLOW-2000

Vadose zone flow using Richards Equation

Overland flow using 2D kinematic flow approximation

Adaptive time stepping algorithm

Equation linearization techniques

Coupled open-channel flow simulation using DAFLOW

Stream / river network flow using diffusion wave analogy

Reactive contaminant transport simulation

Subsurface contaminant transport using RT3D

Open-channel transport using BLTM

Modeling Studies

Vadose zone flow and transport	Conjunctive surface-subsurface flow
Investigating the 'transmissivity feedback' theory in Sleepers River, VT	Watershed flowpath comparison study
