The Relationships Between Benthic Macroinvertebrate And Local Water Quality And Physical Habitat Characteristics In The Rio Chama, New Mexico, Monika Hobbs Oct 2020

The Relationships Between Benthic Macroinvertebrate And Local Water Quality And Physical Habitat Characteristics In The Rio Chama, New Mexico, Monika Hobbs

Water Resources Professional Project Reports

Incorporating the process of adaptive management in rivers management can assist with mitigating impacts of altered streamflow and prevent loss of aquatic biodiversity. Streamflow regimes are important drivers of stream ecology and structuring adaptive management around benthic macroinvertebrates could be an efficient means to understand ecological responses to management of streamflow regime. Over the past decade, there has been interest in implementing adaptive management practices to managing stream flow in the Rio Chama below El Vado Dam in northern New Mexico. The goal of this research project is to improve understanding of environmental drivers shape the benthic macroinvertebrate communities in …


Climate Change Vulnerability Assessment Of Navajo Nation Water Resources In The San Juan River Basin, Nm: Utilizing Traditional Navajo Ecological Knowledge, Kirena Elana Yanibaa Tsosie Oct 2020

Climate Change Vulnerability Assessment Of Navajo Nation Water Resources In The San Juan River Basin, Nm: Utilizing Traditional Navajo Ecological Knowledge, Kirena Elana Yanibaa Tsosie

Water Resources Professional Project Reports

The Navajo Nation consists of 110 chapters, local government subdivisions, organized into five regional agencies. Over half of the Navajo Nation chapters have traditional names in the Navajo language that describe a local water source including springs, washes, rivers, ponds, and reservoirs. Therefore, traditional Navajo names consist of Traditional Navajo Ecological Knowledge (TNEK) and can assist in documenting water sources that can be further assessed for vulnerability and sensitivity to climate change. There are 52 Navajo Nation chapters located in the San Juan River Basin and 28 chapters have water related names. Water sources associated with place names will also …


Measuring Variability Of A Moderate Snowpack Across A Forest Stand Boundary In The Sandia Mountains, Adrian Marziliano Oct 2020

Measuring Variability Of A Moderate Snowpack Across A Forest Stand Boundary In The Sandia Mountains, Adrian Marziliano

Water Resources Professional Project Reports

Mountain snowpacks provide much of the water resources for the southwestern United States. Due to limited freshwater supply and mounting climate stressors, accurate water budget forecasts have become increasingly important. Many regions, such as the lower-elevation mountains found in central New Mexico, lack valuable snow data that could improve these forecasts. The purpose of this research project is to measure and analyze the variability of a moderate snowpack in this region to better understand the representativeness of snow depth distribution and more accurately estimate snow water equivalence (SWE). A survey site with a 1,200 square meter plot in the eastern …


The Role Of Regulatory Agencies In The Frequency And Occurrence Of Health-Based Violations At Public Water Systems In The United States, Rose Afandi Jul 2020

The Role Of Regulatory Agencies In The Frequency And Occurrence Of Health-Based Violations At Public Water Systems In The United States, Rose Afandi

Water Resources Professional Project Reports

The Safe Drinking Water Act (SDWA) was implemented in the United States (U.S.) in 1974 for the purpose of protecting consumers from water contaminants. The Federal government gave the Environmental Protection Agency (EPA) the authority to delegate the responsibility of ensuring that States, Sovereign Nations and U.S. territories meet specific requirements upon being granted primacy to regulate all public water systems (PWSs) in their jurisdiction. An examination of seven years (2013-2019) of SDWA compliance data from all PWSs in the U.S. revealed trends within various categories of regulating agencies that could create disparities in how water systems are regulated. Analyses …


Horton Complex Stormwater Analysis And Management Plan, Bradley D. Meyer Jul 2020

Horton Complex Stormwater Analysis And Management Plan, Bradley D. Meyer

Water Resources Professional Project Reports

Flooding, water quality degradation and erosion are some of the negative impacts created by poorly managed urban stormwater runoff. Managing runoff is an ongoing challenge for watershed managers because of the constantly changing landscape due to development and redevelopment. The Village of Ruidoso in South Central New Mexico is an example of an urban area that is taking an innovative and progressive approach to stormwater management. The focus of this professional project was to perform a stormwater analysis for the Village of Ruidoso, apply it to the Horton Complex – an old school complex that the Village acquired and wants …


Examining Transmission Loss Availability For Basin Aquifer Recharge From Perennial Streams In The Chuska Mountains On The Navajo Nation, Griffin Nuzzo Jul 2020

Examining Transmission Loss Availability For Basin Aquifer Recharge From Perennial Streams In The Chuska Mountains On The Navajo Nation, Griffin Nuzzo

Water Resources Professional Project Reports

Stream transmission losses due to infiltration from semiarid, perennial streams are important processes that can help water managers and users quantify aquifer recharge. Transmission losses are streamflow reductions that are due to infiltration through the streambed, evapotranspiration, and losses to the floodplain or streambanks (Shanafield, et.al, 2014). Transmission losses from infiltration will always be greater than the amount recharged bacause streamflow hat infiltrates into the streambed can take a variety of pathways other that recharge. This study considers transmission losses in Whiskey Creek, a perennial stream on the Navajo Nation in the Chuska Mountains. The objectives of this study are …


Who Decides: Is Water Life Or Capital? Contesting Visions Of Western Water Management In The 21st Century, Ceorl Apr 2020

Who Decides: Is Water Life Or Capital? Contesting Visions Of Western Water Management In The 21st Century, Ceorl

Water Resources Professional Project Reports

There is an ideological divide between the goal of universal access to clean water and the outcomes of how water regulations are implemented. John Fleck, author of Water is for Fighting Over: and Other Myths about Water in the West and Sivas, et al. in California Water Governance in the 21st Century present contesting prescriptions for Western water management. The ideologies advocated by Fleck and Sivas, et al. differ as to who enacts and profits from each and exemplify the divide between the goals of water regulations and how they are implemented. Fleck regards water as property and an economic …
