Watershed health: An evaluation index for New Mexico

Publications Posted on: August 06, 2010
Although watersheds are not equally healthy, there are no generally accepted criteria for evaluating and comparing them. This paper suggests several criteria which numerically evaluate watersheds in four ways: (1) riparian health, (2) aquatic macroinvertebrate biodiversity, (3) hillslope soil loss and (4) upland land use/flood peak potential.

Response of vegetation, soil nitrogen, and sediment transport to a prescribed fire in semiarid grasslands

Publications Posted on: August 06, 2010
Shrubs and trees have invaded semiarid grasslands throughout much of the Southwestern United States. This invasion not only has decreased grass cover, but also increased runoff and erosion. In fact, sediment from rangelands constitutes the single largest source of nonpoint stream pollutants within the state of New Mexico.

Methods for increasing biodiversity in wetland creation and restoration efforts

Publications Posted on: August 06, 2010
Many wetland creation and restoration projects have successfully restored or created appropriate hydrologic conditions for the support of wetland ecosystems but have not been as successful in establishing a diverse biota of native wetland vegetation.

Albuquerque's constructed wetland pilot project for wastewater polishing

Publications Posted on: August 06, 2010
The City of Albuquerque has funded the Constructed Wetland Pilot Project (CWPP) since 1995 at the City's Southside Water Reclamation Plant (SWRP).

Salinity management in the Rio Grande Bosque

Publications Posted on: August 06, 2010
This paper discusses management options for salinity control in the Rio Grande Bosque. First, salt sources are identified and quantified. Capillary rise of ground water is the most important cause for soil salinization in the bosque. Next, a riparian salt balance is presented to explain the different mechanisms for soil salinization.

Upper Rio Grande water operations model: A tool for enhanced system management

Publications Posted on: August 06, 2010
The Upper Rio Grande Water Operations Model (URGWOM) under development through a multi-agency effort has demonstrated capability to represent the physical river/reservoir system, to track and account for Rio Grande flows and imported San Juan flows, and to forecast flows at various points in the system. Testing of the Rio Chama portion of the water operations model was completed in March 1998.

Simulation of Rio Grande floodplain inundation Using FLO-2D

Publications Posted on: August 06, 2010
Spring floodplain inundation is important to the natural functions of the Rio Grande bosque biological community including cottonwood tree germination and recruitment. To predict floodplain inundation, a two-dimensional flood routing model FLO-2D will be applied to various reaches of the Rio Grande.

Watershed/river channel linkages: The Upper Rio Grande Basin and the Middle Rio Grande Bosque

Publications Posted on: August 06, 2010
There continues to be a great deal of interest and discussion surrounding the demands of water management and allocation and the relationship to ecological integrity of the Rio Grande riparian ecosystem. Current river management too often fails to consider the importance of natural variability of flows. What is consistently overlooked is the relationship of a stream course to its forming watershed.

Rio Grande/Rio Bravo Basin Coalition

Publications Posted on: August 06, 2010
In June 1994, one hundred people gathered for the first Uniting the Basin Conference in El Paso to discuss the state of their basin and to explore ways to improve its sustainability for future generations.
