Findings and lessons learned from the assessment of the Mexico-United States transboundary San Pedro and Santa Cruz aquifers: The utility of social science in applied hydrologic reasearch
Groundwater, the "invisible water," is difficult to assess, manage and govern for many reasons, mostly due to the unknown quantities of the resource. Political boundaries dividing groundwater aquifers make assessment even more challenging. This article focuses on lessons learned from the hydrologic assessment of the Transboundary San Pedro and Santa Cruz aqufiers. The authors conducted the work in two phases: (1) laying the groundwork and (2) implementation. The "laying the groundwork" phase consisted of binational meetings with stakeholders and key actors (agencies and individuals), and the...

State-level Groundwater Governance and Management in the U.S.: Summary of Survey Results of Groundwater Quality Strategies and Practices
Groundwater governance and management practices vary considerably across the United States. To better understand groundwater governance strategies and practices connected to water quality in the United States, a team from the University of Arizona Water Resources Research Center designed and launched a nationwide survey in 2016. The goal of the project was to identify on-the-ground practices of groundwater governance that may help to improve and enhance management of the nation’s water supplies, particularly within the realm of groundwater quality. A state water professional was recruited in...

Critical Issues Affecting Groundwater Quality Governance and Management in the United States
Groundwater is increasingly important for meeting water demand across the United States (U.S.). Forward thinking governance and effective management are necessary for its sustainable use. In the U.S., state governments are primarily responsible for groundwater governance (i.e., making laws, policies, and regulations) and management (i.e., implementation of laws, policies, and regulations). This decentralized system results in diverse strategies and practices. We surveyed a water quality professional from each state to better understand commonalities and differences across states. These...

Evaluating Gravity-Flow Irrigation with Lessons from Yuma, Arizona, USA
Many consider gravity-flow irrigation inefficient and deride its use. Yet, there are cases where gravity-flow irrigation can play an important role in highly productive and profitable agriculture. This perspective article reviews the literature on the profitability and efficiency of gravity systems. It then reviews the history of water management in Yuma, Arizona, which is one of the most productive agricultural areas in the United States. Through extensive changes in irrigation technologies, changes in production practices, and investments in irrigation infrastructure, Yuma agriculture...

Breaking Down the Walls
The Roman Empire was known for many remarkable engineering achievements, including roads that straddled continents and aqueducts capable of conveying life-sustaining water into ever-growing cities at the heart of the empire. Researchers tracing the history of Roman infl uence in Great Britain, however, long wondered how one critical, remote outpost in the northern part of the country could have maintained itself and persisted for decades without a source of water.

The Cooperative Framework for the Transboundary Aquifer Assessment Program: A Model for Collaborative Transborder Studies
Membership on the Transboundary Aquifer Assessment Program (TAAP) team continues to be gratifying. The late 2016 publication of the Binational Study of the Transboundary San Pedro Aquifer by the International Boundary and Water Commission marked a milestone. This study is noteworthy in that it is a first-ever binationally prepared, fully bilingual aquifer assessment along the border shared by the United States and Mexico, and because it was subject to peer review on both sides of the border.

Desert Flows Methodology Guidebook
Successful implementation of environmental flow projects depends on land and water managers having clear objectives and access to reliable data. This guidebook provides information on a variety of methods that can be utilized under different fiscal or temporal constraints to determine and implement appropriate environmental flow targets. Based on evidence from cases focused in the Southwestern United States and Northern Mexico, steps are suggested to help ensure maintenance of flows under uncertain future natural and socio-economic conditions. The importance of education and engagement to...

Desert Flows Assessment
In the past decade there has been increased interest in providing water to meet the needs of riparian and aquatic ecosystems in the western United States and policymakers are using their knowledge of environmental flow needs to advocate for both political and scientific changes. However, there are significant challenges associated with including environmental flows in water management and planning. First, water rights for environmental flows are not universal, and in many cases legal tools used to incorporate the environment into water management and planning only require new users to...

Arizona Environmental Water Needs Methodology Guidebook
Arizona Environmental Water Needs (AzEWN) Methodology Guidebook: Determining the best methods or quantifying environmental flow needs depends on what is to be studied as well as how the information will be used. This guidebook will provide a description of the methodologies used in Arizona to define the environment’s need for water. Depending on the geographic context, the time and effort available, and whether the goal is restoration or maintenance of an ecosystem, some methods will be more appropriate for a given application than others. The resulting flows prescribed by each method...
