Integrated hydrologic modeling of a transboundary aquifer system — Lower Rio Grande (original) (raw)
For more than 30 years the agreements developed for the aquifer systems of the lower Rio Grande and related river compacts of the Rio Grande River have evolved into a complex setting of transboundary conjunctive use. The conjunctive use now includes many facets of water rights, water use, and emerging demands between the states of New Mexico and Texas, the United States and Mexico, and various water-supply agencies. The analysis of the complex relations between irrigation and streamflow supply-and-demand components and the effects of surface-water and groundwater use requires an integrated hydrologic model to track all of the use and movement of water. MODFLOW with the Farm Process (MF-FMP) provides the integrated approach needed to assess the stream-aquifer interactions that are dynamically affected by irrigation demands on streamflow allotments that are supplemented with groundwater pumpage. As a first step to the ongoing full implementation of MF-FMP by the USGS, the existing mod...

Water resource management requires collaborative solutions that cross institutional and political boundaries. As key technical contributors to solving critical resource and security problems on a national scale, Sandia National Laboratories are well positioned to team with federal, state, and local water experts to model growing water concerns in the country. Unlike the traditional approach of compartmentalization of tasks and expertise, Sandia utilizes a collaborative modeling approach that is inclusive, multidisciplinary, quantitative, and transparent to all interested parties. A system dynamics (SD) approach forms the basis for the simulation models. We illustrate this process with a water balance model of the Gila-San Francisco River Basin (Gila Basin) in southwestern New Mexico. Teaming with key stakeholders over a course of eighteen months, a system-dynamics hydrologic model is built in response to the terms of 2004 Arizona Water Settlements Act to assess the existing use of w...
