The MODFLOW One-Water Hydrologic Flow Model (MF-OWHM; Boyce and others, 2020Hanson and others, 2014) is a MODFLOW-2005 based integrated hydrologic model designed for the analysis of conjunctive-use management. The term “integrated” refers to the tight coupling of groundwater flow, surface-water flow, landscape processes, aquifer compaction and subsidence, reservoir operations, and conduit (karst) flow. This fusion results in a simulation software capable of addressing water-use and sustainability problems, including conjunctive-use, water-management, water-food-security, and climate-crop-water scenarios.  

MF-OWHM is based on the Farm Process for MODFLOW-2005 (MF-FMP2, Schmid and Hanson, 2009) that includes Surface-water Routing Process (SWR, Hughes and others, 2012), Seawater Intrusion (SWI, Bakker and others, 2013),Riparian Evapotranspiration (RIP-ET, Maddock III and others, 2012), and Conduit Flow (CFP Shoemaker and others, 2008). MF-OWHM contains all the previously available solvers and the new solvers such as Newton-Raphson (NWT, Niswonger and others, 2011) and the nonlinear preconditioned conjugate gradient (PCGN, Naff and Banta, 2008). 

As a second core version of MODFLOW-2005, MF-OWHM maintains backward compatibility with existing MODFLOW-2005 versions. Existing models developed using MODFLOW-2005 (Harbaugh, 2005), MODFLOW-NWT (Niswonger and others, 2011), MODFLOW-CFP (Shoemaker and others, 2008), and MODFLOW-FMP (Schmid and others, 2006; Schmid and Hanson, 2009) can also be simulated using MF-OWHM.

The improvements, new features, modifications to MODFLOW-2005, and newly developed processes continue the MF-OWHM philosophy of retaining and tracking as much water as is feasible in the simulation domain. This philosophy provides the scientific and engineering community with confidence in the water accounting and a technically sound foundation to address broad classes of problems for the public.

MF-OWHM uses a physically based simulation that is connected to a supply and demand framework. This framework starts with the landscape’s demand for water consumption that originates from either an administrative requirement—such as urban consumption or managed aquifer recharge—or from the landscape surface’s potential evaporation and transpiration. This “landscape water demand” is then satisfied from available supplies of water—such as precipitation, surface water, groundwater, and imported water. Water supply can be limited due to physical constraints from the natural and engineered water systems. These constraints occur due to the physics of natural groundwater and surface water flow and to physical limits of engineered systems, such as diversion canals or well-production capacity. The landscape water demand can affect both surface water and groundwater due to their interconnectivity. Further, the supply of groundwater and surface water can be controlled by water rights, managed through reservoir operations, or limited due to regulations.

Note that precipitation is not included in figure, but is a source of water that could potentially reduce the landscape water demand and increase aquifer storage and stream flow (Boyce and others, 2020).  (Public domain.)

 

Program History

Version Highlights

MF-OWHM v2.00 is the second major release of MF-OWHM. This version involved a total rewrite of the Farm Process (FMP), inclusion of the Conduit Flow Process (CFP Shoemaker and others, 2008), and modifications that improved all the base MODFLOW packages. 

MF-OWHM v1.00 was the first major release of MF-OWHM that is a unification of the many separate versions of MODFLOW that have evolved for various classes of hydrologic issues. In addition to this, modifications were made to the MF2005 source code that improve stability, accuracy and make the resulting software more "user friendly". MF-OWHM v1.00 is now considered legacy code with minimal support. 

Version Information and Notes

MF-OWHM v2.00.00 04/7/2020 is the initial release of version 2. 

Note: Users are encouraged to read the documents that are provided in the 'doc' directory of this software distribution.
