MW&A was founded in the early 1990s to provide advanced hydrologic and programming capabilities toward solutions of modeling and stochastic challenges in the earth sciences. Recently MW&A has achieved breakthrough performances in practical hydrologic forecasting extending from monthly to decadal time scales.
I am a practicing hydroclimatologist who is also enrolled in a Ph.D. program in the Department of Nanoscience and Microsystems at the University of New Mexico. My work in progress there relates to hydroclimatology and solar cycles.

Expert consultant to U.S. Army Corps of Engineers (Department of Defense), as a review panel member concerning a long-term regional groundwater flow model developed for the City of Gallup, New Mexico. This is popularly known as the G-22 Experts Panel. Hearing No. 99-003-OSE File No. G-22 and more.
Yucca Mountain Hydrology and Earth Sciences Support, Nevada. I was the primary internal reviewer of the Yucca Mountain surface-water model and coupled recharge study. The Yucca Mountain Project was designed to be the nation’s first geologic repository for long-term disposal of commercial spent nuclear fuel. I led a staff of approximately ten earth scientists, including six staff members of Idaho National Laboratory (INL); one engineer; and one staff member on loan from the Long Term Ecological Research Program, headquartered at the University of New Mexico (UNM). This team reviewed an extensive effort led by Sandia National Laboratories (SNL) to produce a defendable, predictive model of the climate driven infiltration regime of Yucca Mountain, following past efforts led by the U.S. Geological Survey (USGS).
In 2004, I served as primary reviewer of the 3D site-scale saturated zone model (employing the FEHM code) of the Yucca Mountain area conducted by scientists at Los Alamos National Laboratories. For Sandia National Laboratories and Bechtel-SAIC, I implemented a qualification effort for the structural mechanics code JAS3D. JAS3D is a 3D finite element program designed to solve large quasi-static nonlinear mechanics problems. I also implemented a qualification effort for the ASHPLUME code that simulates plume development and atmospheric transport of ash and tephra caused by volcanic events.
In 2002–2003, I supported an investigation of thermal transport within the saturated zone underlying Yucca Mountain. My contributions focused on qualification of measured and inferred thermal properties of the host aquifers. In 2005, I conducted a software qualification effort for a submodule of the software code TOUGHREACT. The TOUGHREACT code is part of the TOUGH2 framework of 3D multiphase, non-isothermal groundwater and heat transport codes. TOUGHREACT adds reactive geochemistry to the solution methodologies of TOUGH2.
Waste Isolation Pilot Project Hydrologic and Earth Sciences Support, Carlsbad, New Mexico. I was involved in several areas of the Waste Isolation Pilot Project (WIPP)—the nation’s first geologic repository for the long-term disposal of defense-generated nuclear waste. I was the principal analyst in a groundwater flow and transport modeling effort for the WIPP Performance Assessment (PA) program. I was the principal investigator on the first effort to determine that potash mining-induced subsidence would benefit the natural hydrologic long-term containment capabilities of the WIPP repository. In addition, I developed the first water table contour surface for the WIPP vicinity while I was a principal investigator on seven scenario screening efforts for WIPP. I served as a coinvestigator in a 3D paleohydrological/climate change consequence modeling study of the upper groundwater system and its relation to surface water flow in the WIPP region. This included the modification of the MODFLOW code to implement a novel-free surface boundary condition. I co-developed a numerical simulator using and modifying the simulators SUTRA and EQ36 that analyzed the coupled processes of salt creep and brine inflow related to excavations into the Salado Formation at WIPP.
2014 MW&A was recognized in appreciation of a presentation on ocean cycles and correlations to the US Southwest climate at the New Mexico Mining Association Annual Convention in Santa Fe, NM.
2005 I was the principal investigator for this project, ultimately funded by the US DOE to employ a modern day video game engine, coupled with a Latin Hypercube Simulator (LHS) to produce a stochastic set of possible outcomes of scenarios in which volcano-meets-repository, based on the best analyses of an international team of volcanologists, physcists, rock mechanics simulators, and hazard quantification experts. Many thanks to all who contributed especially Harold Iuzzolino!
This NMITSA award program was cosponsored by Intel and Los Alamos National Laboratory. Among the finalists in the Innovative
Research category were Redfish and Sandia National Laboratories.
MWA won in this category.
2000 Technology Ventures Corporation, a wholly owned subsidiary of Lockheed Martin, Corp. awarded my startup company Global Haptics, Inc., a $10,000 Roadrunner Grant for best business plan, which I authored. The plan concerned a venture based on my patented invention of a tactile computer aided interface device known as an Orb. Citations to the Orb patents are now present in nearly 70 contemporary patents, including haptic inventions by Microsoft, Sony, Xerox, and Immersion Corp.
1998 I was the Art Director for the Calabacillas Arroyo project which has won three independent design/engineering awards.
1999 Eastern Navajo Community presented this award for my expert witness work in helping to protect their sole-source water supply from a proposed in situ leachate (ISL) uranium mine which was planned within the same aquifer, only a few thousand feet away. Up to 15,000 residents in the region make weekly trips (some driving as far as 50 miles) to a handful of water supply wells tapping into the aquifer of concern, for their drinking and washing needs. I demonstrated the risk that the proposed mine posed to that water resource and successfully sustained my assertions against over half a dozen opposing expert witnesses.
This effort was paralleled by previous work I conducted for the same indigenous communities, centered around the UNESCO World Heritage Site Chaco Canyon, to prevent the oil and gas industry from continuing their widespread practice of simply pouring their contaminated waste products directly into the ground (thereby contaminating soil and groundwater). In that case my testimony withstood challenges by several opposing experts from several consulting firms, resulting in regulations that applied additional safeguards to disposal practices within that region.
