The Rio Grande and its riparian corridor also support thousands of species of plants, invertebrates and vertebrates, some of which include over 300 species of migratory birds and the endangered Rio Grande silvery minnow and southwestern willow flycatcher. Eutrophication and salinization are the two most important types of water quality degradation which negatively impact the human and nonhuman biological communities in this water poor region. In spite of their significance, few published studies have investigated anthropogenic and natural sources of nutrients and dissolved solids to the Rio Grande. This study investigated the patterns and trends of nutrients and dissolved solids in the Middle Rio Grande (MRG) on a monthly basis from September 2005 – January 2008. During all months, wastewater treatment plants were the major source of nutrients to the MRG. Under high flow conditions, nutrient levels remained elevated for 260 river kilometers below the wastewater inputs. During months when significant portions of the river flow were diverted for irrigation, nitrate and phosphate were removed from the MRG and concentrations at the downstream end of the reach were returned to levels comparable to the un-impacted northern reach of river. Dissolved solids were added to the river by both wastewater and saline tributary inputs. Both anthropogenic and natural inputs of dissolved solids were found to affect water quality in the MRG. Continuous real-time measurements of temperature, pH, turbidity, dissolved oxygen, and conductivity also were initiated at four sites above and through the urban reach of the City of Albuquerque. Preliminary results show increasing turbidity and dissolved oxygen depletions associated with storm runoff from urban areas.Â
Sensitivity of one-dimensional hydrologic model simulations: A model study of Lemes Canyon, New Mexico
No full textA Professional Project Report submitted in partial fulfillment of the requirements for the degree of Master of Water Resources, Water Resources Program, University of New Mexico.Stream channel restoration can increase flow storage and energy dissipation of passing flood waves (Sholtes and Doyle, 2011). Reestablishment of floodplain hydraulic function and increasing floodplain connectivity are increasingly goals of restoration programs, yet the magnitude of possible change to a range of variables remains poorly quantified Bernhardt and Palmer, 2011; Sholtes and Doyle, 2011). This study utilizes HEC-RAS to route floods under steady state, subcritical conditions in field-based impaired reach scale models. The study integrates collected channel data from Lemes Canyon, an ungaged ephemeral channel located near Monticello, NM as well as USGS topographic data (7.5 minute; 1:24,000) to construct a model at the reach scale. Peak discharge values were estimated using the USGS Generalized Least Squares Regression for Ungaged Streams. This study performed sensitivity analyses of one-dimensional hydrologic model simulations to quantify the magnitude of change with respect to two response variables, average total velocity and hydraulic depth, respectively. In this study synthetic ineffective flow areas were used as a proxy for engineered log jams to test the hypothesis of equal population means against the alternative that not all population means are equal for the two response variables among ten geometric plans. A One Way Analysis of Variance (ANOVA) of means among populations was performed to test the hypothesis for both response variables. At the .05 level, no statistically significant results were found. The results

from this study indicate there are no statistically significant differences in mean values with respect to the two response variables among all ten populations considered.
These results suggest there is no statistical evidence that ineffective flow areas as a proxy for log jams are effective at decreasing the average velocity or increasing the hydraulic depth at the reach scale. The statistical results identify the relative importance of hydrologic design elements used in channel reconfiguration projects among ephemeral and intermittent channels in arid and semi-arid climates
