Opportunities To Enhance Environmental Flows On The Rio Chama, Anjali Bean
Opportunities To Enhance Environmental Flows On The Rio Chama, Anjali Bean
Water Resources Professional Project Reports
The construction of El Vado dam on the Rio Chama in 1935 dramatically changed the natural flow of the river, reducing spring runoff and summer scouring floods in favor of providing a constant water supply to downstream users. The San Juan-Chama Project, a trans-basin water diversion built as part of the Colorado River Compact, also significantly increased water flow in the river, a unique situation in the state of New Mexico. This increase in management of the river for human benefit has permanently altered the natural hydrograph of the river and the ecology and geomorphology of the system that depends …
Surface-Water Groundwater Interactions In The Middle Rio Grande, Nm Implications For Bank Storage And Native Species, Tom Heller
Water Resources Professional Project Reports
Riparian zones are important for ecological purposes and ecosystem processes, and are valued for aesthetic, recreational, cultural, and historical reasons. The declining integrity of cottonwood-dominated riparian systems in the Middle Rio Grande (MRG) of central New Mexico has been evident for several decades, of which the largest cause has been the severe alterations riparian hydrology. While cottonwood germination responses to changing flood regimes have been well studied, the response to changing groundwater dynamics - and the suitability of groundwater regimes in the MRG - is less well understood. This study used pressure transducer groundwater datasets installed in the Rio Grande …
Providing Water For A Forgotten People: A Waterline Assessment Of The Former Bennett Freeze Area, Nikki Rae Tulley
Providing Water For A Forgotten People: A Waterline Assessment Of The Former Bennett Freeze Area, Nikki Rae Tulley
Water Resources Professional Project Reports
The Bennett Freeze was established in 1966 and imposed for 40 years on 1.5 million acres of land within the boundaries of the Western Agency of the Navajo Nation. Bennett Freeze came as a result of the Navajo-Hopi Land Dispute. The “freeze” halted all construction, development, and improvements made to enhance the quality of life within the boundaries of the Bennett Freeze area. Public works were included in the restrictions created by the freeze, which effectively denied residents access to basic sanitation facilities. There are approximately 2,685+ homes (~20,000 residents) within the Former Bennett Freeze Area (FBFA) without access to …
A Real-Time Data Monitoring Prototype Protocol To Advance Environmental Management Through A Citizen Science Approach– A Case Study In Nepal, Corinne Fox
Water Resources Professional Project Reports
The lack of environmental monitoring data has restricted the efficiency of proper environmental management in the developing world. Although monitoring technologies have been touted for their potential to advance environmental understanding and management, there are very few examples of practical applications where this has been accomplished in the developing world. Due to the positive influx of urbanization and tourism in Siddharthanagar, South Nepal, the Nepal Study Center (NSC) from the University of New Mexico (UNM) teamed up with the poly-tech college Pratiman-Neema Health Institute (PNMHI) to address future environmental changes through a citizen science approach, known as the Danda River …
How A Brownfield Redevelopment Planning Effort In Gallup Resulted In A New Regulation For Vapor Intrusion In New Mexico, Michelle G. Hunter
How A Brownfield Redevelopment Planning Effort In Gallup Resulted In A New Regulation For Vapor Intrusion In New Mexico, Michelle G. Hunter
Water Resources Professional Project Reports
The Puerco River basin has, within its confines, one small city, Gallup, New Mexico. Gallup is located within close proximity to the Navajo Nation, and many Navajo Nation members live and work in Gallup and need affordable housing. A local Gallup non-profit proposed a multi-family housing development on a long-vacant, and blighted property in the middle of downtown Gallup. After several environmental assessment investigations, the developer discovered significant groundwater contamination, from an adjacent dry cleaner, that had the potential to migrate into the indoor air at the future housing facility. A series of brownfield assessment, planning, and cleanup efforts resulted …
An Update And Analysis Of The Corrales Bosque Preserve Vegetation Map, Brett Feldhahn
An Update And Analysis Of The Corrales Bosque Preserve Vegetation Map, Brett Feldhahn
Water Resources Professional Project Reports
An updated vegetation map of the Corrales Bosque Preserve in Corrales, New Mexico was developed for this project using Hink and Ohmart community-structure survey protocol and vegetation classifications. The vegetation composition was analyzed and compared to the Middle Rio Grande Conservation Action Plan (MRG-CAP) rating criteria for dynamic mosaic vegetation, also known as the Dynamic Patch Mosaic (DPM). The DPM attribute indicates the mix of vegetation community types—the vegetation mosaic—that facilitates the best outcome for ecosystem resilience and biodiversity in the bosque. The updated vegetation community-structure types were used to classify each polygon into general vegetation types per the MRG-CAP, …
Bank Erosion Control: Rio Pueblo De Taos, Noelani Eba-Jah-Mi Villa
Bank Erosion Control: Rio Pueblo De Taos, Noelani Eba-Jah-Mi Villa
Water Resources Professional Project Reports
Bank failure can occur from multiple reasons including geotechnical failure, failure from hydraulic forces, or a combination of both. Hydraulic failure is driven by a lack of vegetation, high boundary velocities, and toe scour. Erosion from hydraulic forces is often related to flow velocities or direction (Baird, 2005). Large-scale bank erosion is initiated by failure of bank materials at the base or toe of the outer bank (Sclafani, 2011). The Taos Pueblo are concerned with channel migration which has caused bank failure of the Rio Pueblo along Pueblo Canyon Road leading to the sacred Blue Lake. The objective of this …
