Water conservation methods to conserve the High Plains aquifer and Arikaree River Basin: a case study on the Arikaree River
… Colorado, is groundwater dependent on the High Plains aquifer (HPA). The river alluvium is habitat for threatened fish species such as the Hybognathus hankinsoni (Brassy Minnow) and habitat for many terrestrial invertebrates. In addition to the demands for maintenance of habitats, the …

GPS Imaging of Vertical Land Motion and Earthquake Coseismic Displacements in the GPS Mega-Network
… is subsiding at approximately -2 mm/year, a rate higher than surrounding subsidence, and is located at latitudes corresponding to the Cascadia subduction zone and approximate longitude of the Cascadia arc. Several methods tested the resolution of GPS Imaging and changes to the regional signal over …

Agent-based models to couple natural and human systems for watershed management analysis
… pumping decision-making processes in the High Plains aquifer within the hydrological observatory area. The resulting agent-based models (ABMs) are coupled with a physically-based groundwater model to investigate the interactions between farmers and the underlying groundwater system. With …

Trends in Virtual Water Export from the High Plains, 1950-2010
… of the trade of agricultural products. The High Plains region in the central United States has experienced large land use change during the last 150 years, from grassland to one of the country’s main agricultural areas. One driver was water provided by the High Plains aquifer. The purpose of …

Three essays on the economics of water management in agriculture
… imposed on groundwater flow rates by underlying aquifer characteristics. I find that limitations on the instantaneous supply of groundwater can affect irrigation decisions nonlinearly with a threshold effect. A profit-maximizing farmer with maximum available water flow rate below the threshold …

Assessing long-term conservation of groundwater resources in the Ogallala Aquifer Region using hydro-agronomic modeling
… irrigation water for crop cultivation. The High Plains Aquifer (HPA) is the largest freshwater aquifer in the United States and has experienced severe depletion in the past few decades due to excessive pumping for agricultural irrigation. There is a need to determine management strategies …

Base Flow Recession Analysis for Streamflow and Spring Flow
… characteristics of streamflow are found to be highly correlated, suggesting a fundamental linkage between the transition of base flow recession from early to late stages and the drying up of ephemeral streams. At the early stage, the contraction of ephemeral streams mostly controls the …

Studying coupled human and natural systems from a decentralized perspective: the case of agent-based and decentralized modeling
… coupled with a model of groundwater flow and aquifer/stream interactions, we studied the role of individuals in a coupled agricultural and hydrologic system. The model was designed to simulate the interactions between farmers pumping groundwater to irrigate their corn fields and the water …
