One-line model description
PIHM is a multiprocess, multi-scale hydrologic model.
Extended model description
PIHM is a multiprocess, multi-scale hydrologic model where the major hydrological processes are fully coupled using the semi-discrete finite volume method. PIHM is a physical model for surface and groundwater, “tightly-coupled” to a GIS interface. PIHMgis which is open source, platform independent and extensible. The tight coupling between GIS and the model is achieved by developing a shared data-model and hydrologic-model data structure.

Describe input parameters
PIHM is an integrated finite volume hydrologic model. It simulates channel routing, overland flow and groundwater flow in fully coupled scheme. It uses semi-discrete Finite Volume approach to discretize PDE (equations governing physical processes) into ODE to form a system of ODEs and solved with SUNDIALS solver (LBL).
PIHM incorporates an object-oriented model data structure which provides extensibility and efficient storage of data at the same time. PIHM v2.0 requires the following input files:
projectName.txt : This file will have the project name as its content.
.mesh File : Spatial information of Nodes and Irregular Meshes (TINs)
.att File : Attribute defining different classes an element belongs to
.soil File : Soil properties
.geol : Geologic properties
.lc file : Vegetation parameters of different land cover types
.riv file : Spatial, geometry and material information of river segments
.forc file : All the forcing variables (forcing time-series)
.ibc file : Boundary condition information for elements
.para file : Control parameters (solver options; model modes; error control)
.init : If initial condition input is through a file
.calib : Calibration parameters and process controls

Describe processes represented by the model
The Penn State Integrated Hydrologic Model (PIHM) is a fully coupled multiprocess hydrologic model. Instead of coupling through artificial boundary conditions, major hydrological processes are fully coupled by the semi-discrete finite volume approach. For those processes whose governing equations are partial differential equations (PDE), we first discretize in space via the finite volume method. This results in a system of ordinary differential equations (ODE) representing those procesess within the control volume. Within the same control volume, combining other processes whose governing equations are ODE’s, (e.g. the snow accumulation and melt process), a local ODE system is formed for the complete dynamics of the finite volume.
Describe key physical parameters and equations
Processes include: 2-D overland flow, 2-D groundwater flow, 1-D soil moisture, 1-D channel flow, snow/melt, et, vegetation water use by NLCD,
Describe length scale and resolution constraints
typically based on original DEM used to develop the watershed model
Describe time scale and resolution constraints
fully implicit, time adaptive, based on the CVODE ODE solver from LBL
Describe any numerical limitations and issues
Solver is efficient and accurate for very stiff systems of equations
Describe available calibration data sets

Describe ideal data for testing
PIHM is a distributed watershed model that can represent surface/subsurface processes at scales ranging from a few hundred m^2 to 10,000 km^2. However, large systems will require the parallel version currently under development
Do you have current or future plans for collaborating with other researchers?
We have several other extensions to PIHM under development: solute transport, sediment transport, 3-D Richard's Equation. Full information can be found at:

Is there a manual available?
Yes
