The Transboundary Freshwater Dispute Database (TFDD) is a multifaceted global database that began in 1996 and includes a collection of international freshwater treaties, a database of water conflict-cooperation events, and a spatial database. Delineations of transboundary international river basin boundaries are the focus of the spatial database of which population,...
In the face of the global climate crisis, paired with current and future risks over water resources, the importance of effective water resources management cannot be overstated. However, there is a significant lack of specific metrics used to track water stewardship on a broad scale. Thus, in order to track...
West Nile Virus (WNV), a vector-borne disease continues to be a serious threat to public health in the United States, particularly in the Southwest region. While all the states in the U.S. experienced a decreasing trend of WNV disease in 2010, the state of Arizona experienced a sharp increase from...
The Gulf of Alaska (GOA) is home to the most productive fisheries in the world. In 2019, 2.2 million metric tons of fish were shipped from Alaska to destinations all over the world (NOAA Fisheries, 2019). From 2014-2016 and, more recently, in 2019 the largest heatwaves in recorded history caused...
There has been a lot of work done in recent decades in the field of symbolic dynamics.
Much attention has been paid to the so-called "complexity" function, which gives a sense
of the rate at which the number of words in the system grow. In this paper, we explore this...
This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...
Increases in food demand, favorable commodity markets and drive towards increasing productivity at a greater economic efficiency have accelerated negative agricultural
externalities, particularly erosion and water quality. The potential impact of these externalities on environmental quality and human health prompted an examination of current and potential production strategies on four...
A proposed state-and-transition model (STM) for the Deep Sand Savannah ecological site in central New Mexico was developed using historical data and expert knowledge. This STM was tested utilizing data from short and long term one-seed juniper (Juniperus monosperma (Engelm.) Sarg.) control experiments initiated in 1981 and 1985. Utilizing data...
Ventenata dubia L. (ventenata) is an introduced, winter annual grass that has recently been raising concerns across the Pacific Northwest Bunchgrass Prairie and the Palouse Prairie. It is well established now in pasturelands, croplands, and a variety of ecosystems including grasslands, sagebrush steppe, ponderosa pine forests and woodlands. Ventenata is...
