Economic and environmental trade-offs of irrigation best management practices in the Lower Arkansas River Valley
The flows of the Arkansas River cascade through the Rocky Mountains and spill into Colorado's eastern plains. In the Lower Arkansas River Valley (LARV), these flows serve irrigators on over 250,000 acres, and are critical to the production of everything from corn to cantaloupes. Concurrent to the …

Ecosystem impacts of tamarisk (Tamarix spp.) management in the Arkansas River watershed, Colorado: effects of disturbance and herbicide residues on passive plant community restoration
Tamarisk (Tamarix L.) is now one of the most common species of woody plants along waterways in arid and semi-arid areas of the western United States. Tamarisk was intentionally introduced over a century ago for ornamental purposes and erosion control projects, but its expansion since has been …

Investigating best management practices to reduce selenium and nitrate contamination in a regional scale irrigated agricultural groundwater system: Lower Arkansas River Valley, southeastern Colorado
The Lower Arkansas River Valley (LARV) is well known for its rich agricultural production, with 109,000 ha of irrigated area. Due to agricultural production extending for more than 100 years, the LARV now faces challenges of soil salinity, water logging from shallow groundwater tables, and a high …

Reproductive Biology of the Rabbitsfoot Mussel (Quadrula Cylindrica) (Say, 1817) in the Upper Arkansas River System, White River System and the Red River System
… and critically endangered species in the upper Arkansas River system of Kansas and Missouri. I compared reproductive biology and life history of three rabbitsfoot populations. These data are needed for management actions and may also be useful in assessing diversity among rabbitsfoot …

Alkali Silica Reaction Mitigation Using High Volume Class C Fly Ash
… Stanton. Several cases of ASR have occurred in Arkansas near Fayetteville, Pine Bluff, and Little Rock. The purpose of this research was to develop preventative measures using Class C fly ash in concrete, which contains the moderately reactive aggregates found in the Arkansas River.</p> <p>The …

Modeling nonpoint-source uranium pollution in an irrigated stream-aquifer system: calibration and simulation
The Lower Arkansas River Valley (LARV) in southeastern Colorado has been a source of significant agricultural productivity for well over a century, primarily due to extensive irrigation practices. Mirroring trends seen in other semi-arid irrigated areas globally, however, irrigated agriculture in …

A spatial decision support system for basin scale assessment of improved management of water quantity and quality in stream-aquifer systems
Challenges in river basin management have intensified over the years, with expanding competition among water demands and emerging environmental concerns, increasing the complexity of the decision making framework. A State-of-the-art spatial-decision support system (River GeoDSS) is developed herein …

Age, Growth, and Population Structure of Black Redhorse (Moxostoma Duquesnei) and Golden Redhorse (Moxostoma Erythrurum) in Southwest Missouri
… redhorse (Moxostoma erythrurum) from three White River tributaries (James River, Bull Creek, and Swan Creek) and one Arkansas River tributary (Elk River) in southwest Missouri. Validation of annulus formation in otoliths, using marginal increment analysis, indicated that both species formed the …

Development of a model for simulation of solute transport in a stream aquifer system
… transport in the stream-aquifer system of the Arkansas River and the Equus Beds Aquifer in south-central Kansas. Previous modeling of the aquifer was conducted by the Bureau of Reclamation using MODFLOW and MT3D to examine groundwater flow and chloride transport in the aquifer. The flow …

Nonparametric function smoothing: fiducial inference of free knot splines and ecological applications
… this method to macro-invertabrate data from the Arkansas River. Next we investigate a measurement error model and a generalization of the commonly used regression calibration method whereby a nonparametric function is used instead of a linear function. We present a simulation study to assess the …
