Navigating the Future of the Colorado River (Martz Summer Conference, June 8-10)
Competition for scarce Colorado River water resources is nothing new, but the conflicts that prompted the seven basin states to negotiate the 1922 Colorado River Compact have grown considerably fiercer and more complex in recent decades. In 2007, responding to the challenges of increasing demand and sustained drought, the seven basin states and a number of other affected interests agreed to a set of interim guidelines for allocating Colorado River water in the event of shortages. This agreement represents an important evolution in the governance of the Colorado River, suggesting that the many interests in the basin can work together …

From Sink To Resurgence: The Buffering Capacity Of A Cave System In The Tongass National Forest, Usa, Chris Groves, Melissa Hendrikson
Earth, Environmental, and Atmospheric Sciences Faculty Publications
The Tongass National Forest of Southeast Alaska, USA, provides a unique environment for monitoring the impact of the cave system on water quality and biological productivity. The accretionary terrane setting of the area has developed into a complex and heterogeneous geologic landscape which includes numerous blocks of limestone with intense karstification. During the Wisconsian glaciation, there were areas of compacted glacial sediments and silts deposited over the bedrock. Muskeg peatlands developed over these poorly drained areas. The dominant plants of the muskeg ecosystem are Sphagnum mosses, whose decomposition leads to highly acidic waters with pH as low as 2.4. These …

Resource management technical reports
In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. Construction of the M2 supply channel connecting the ORIA and Weaber Plain, and the final period of irrigation design, environmental management and related approval processes commenced later in 2009. This process followed a protracted period of public and private industry planning and environmental assessment (Kinhill 2000). As a part of the environmental planning and approvals process, the WA Government was required to prepare a groundwater management plan and a hydrodynamic plan. These plans were to address potential issues …

Resource management technical reports
As a part of the environmental planning and approvals process, the state government was required to prepare Groundwater Management and Hydrodynamic Plans. These plans are to address potential issues of salinity and water quality that could result from the development of irrigated agriculture on the Weaber Plain. The Weaber Plain groundwater modelling report (KBR 2010a) identified several options to manage watertables and salinity
Production bores 10WP35PB and 10WP36PB were drilled in the palaeochannel on sites selected from the interpretation of airborne geophysics.

My senior project focused on studying saltwater intrusion in a coastal town of New Zealand. I feel lucky that I was able to travel to such a distant place, conduct research that was insightful and interesting, and immerse myself in an international culture all in the name of my education. As a Liberal Arts and Engineering Studies student, I aim to analyze not only the cultural differences and similarities that the foreign environment offers to me but also the detailed, technical, engineering aspect of my research. I believe that my education should be approached with a well rounded perspective that …
The Green, Blue And Grey Water Footprint Of Crops And Derived Crop Products, Mesfin Mekonnen, Arjen Y. Hoekstra
The Green, Blue And Grey Water Footprint Of Crops And Derived Crop Products, Mesfin Mekonnen, Arjen Y. Hoekstra
Daugherty Water for Food Global Institute: Faculty Publications
Abstract. This study quantifies the green, blue and grey water footprint of global crop production in a spatially-explicit way for the period 1996–2005. The assessment improves upon earlier research by taking a high-resolution approach, estimating the water footprint of 126 crops at a 5 by 5 arc minute grid. We have used a grid-based dynamic water balance model to calculate crop water use over time, with a time step of one day. The model takes into account the daily soil water balance and climatic conditions for each grid cell. In addition, the water pollution associated with the use of nitrogen …

Historical Legacies, Information And Contemporary Water Science And Management, Daniel J. Bain, Jennifer A. S. Arrigo, Mark B. Green, Brian A. Pellerin, Charles J. Vörösmarty
Advanced Science Research Center
Hydrologic science has largely built its understanding of the hydrologic cycle using contemporary data sources (i.e., last 100 years). However, as we try to meet water demand over the next 100 years at scales from local to global, we need to expand our scope and embrace other data that address human activities and the alteration of hydrologic systems. For example, the accumulation of human impacts on water systems requires exploration of incompletely documented eras. When examining these historical periods, basic questions relevant to modern systems arise: (1) How is better information incorporated into water management strategies? (2) Does any point …
Melting Trends Over The Greenland Ice Sheet (1958-2009) From Spaceborne Microwave Data And Regional Climate Models, X. Fettweis, Marco Tedesco, M. Van Den Broeke, J. Ettema
Melting Trends Over The Greenland Ice Sheet (1958-2009) From Spaceborne Microwave Data And Regional Climate Models, X. Fettweis, Marco Tedesco, M. Van Den Broeke, J. Ettema
Publications and Research
To study near-surface melt changes over the Greenland ice sheet (GrIS) since 1979, melt extent estimates from two regional climate models were compared with those obtained from spaceborne microwave brightness temperatures using two different remote sensing algorithms. The results from the two models were consistent with those obtained with the remote sensing algorithms at both daily and yearly time scales, encouraging the use of the models for analyzing melting trends before the satellite era (1958–1979), when forcing data is available. Differences between satellite-derived and model-simulated results still occur and are used here to identify (i) biases in the snow models …

This study quantifies and maps the water footprints of nations from both a production and consumption perspective and estimates international virtual water flows and national and global water savings as a result of trade. The entire estimate includes a breakdown of water footprints, virtual water flows and water savings into their green, blue and grey components. The main finding of the study can be summarized as:
The global water footprint in the period 1996-2005 was 9087 Gm3/yr (74% green, 11% blue, 15% grey). Agricultural production contributes 92% to this total footprint.
About one fifth of the global water footprint relates …

Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine
Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine
Department of Environmental Studies: Undergraduate Student Theses
Drought is a reoccurring phenomenon with widespread economic, social, and environmental impacts. Unlike other disasters, a drought cannot be easily detected. In addition, droughts are widespread and develop slowly over time making it difficult to detect its onset and monitor its severity and impacts. To assist in monitoring the severity and spatial extent of droughts, drought managers frequently use indicators and triggers. Drought indicators are meteorological or hydrological variables or indices that quantify or describe the level of drought severity. A drought trigger is a value of an indicator that initiates management and response actions. Despite the clear importance of …
Spatial Distribution And Evolution Of A Seasonal Snowpack In Complex Terrain: An Evaluation Of The Snodas Modeling Product, Brian Trail Anderson
Spatial Distribution And Evolution Of A Seasonal Snowpack In Complex Terrain: An Evaluation Of The Snodas Modeling Product, Brian Trail Anderson
Boise State University Theses and Dissertations
Hydrologists and water managers have been attempting to accurately estimate watershed scale snow water equivalent (SWE) for over a century. Extensive monitoring networks, remote sensing technology, and sophisticated modeling approaches have greatly improved these estimates; however, water inputs from snow in mountainous areas are still subject to considerable uncertainty due to SWE spatial variability. In an attempt to improve the understanding of physical processes and controls influencing SWE spatial variability, a field campaign to measure the spatial and temporal distribution of SWE within the Dry Creek Experimental Watershed (DCEW) was conducted during 2009 and 2010. These measurements are compared to …
Quantifying Evapotranspiration And Water Table Interactions In Regions Of Shallow Groundwater: Sensitivity To Soil Properties, Vegetation, And Climate Variability, Mehmet E. Soylu
School of Natural Resources: Dissertations, Theses, and Student Research
Evapotranspiration (ET) is an important component of the water and energy balance, yet it is also one of the most challenging components to estimate. There has been great effort to understand the nature of controlling mechanisms and interactions between ET and other earth system processes. The controlling factors of ET can be grouped into two broad categories – namely moisture availability and energy availability (e.g., solar radiation). Soil moisture is a key factor that most of the land surface hydrologic processes are dependent on. While plant water use is mainly controlled by radiation, temperature is another key factor for ET …
