Analytical Modeling of Nitrogen Dynamics in Soils and Ground Water

Publikováno v: Journal of Irrigation and Drainage Engineering. 125:330-337

An analytical model, known as RISK-N, is developed to simulate nitrogen cycling in soils, and nitrate transport and fate in soils and ground water. The soil is separated into upper-root, lower-root, and intermediate-vadose zones, each with uniform pr

Best Methods and Inherent Limitations of Bulked Flow Modeling with HEC-RAS

Autor: Jake Gusman, Brent Travis, Martin J. Teal

Publikováno v: World Environmental and Water Resources Congress 2012.

Increasing water discharge to account for a high concentration of sediment in the flow is known as bulking. Although bulked flows are intrinsically non- Newtonian, it is common practice for flows with bulking factors up to 2.0 to be modeled with HEC-

From Auwaiakeakua to Weoweopilau: Assessing Scour Critical Bridges in Hawaii (It's a Tough Job, but Someone Has to Do It)

Autor: Martin J. Teal, Christine Warren, Curtis Matsuda, Jake Gusman, Mike Hunnemann

Publikováno v: Scour and Erosion.

In the State of Hawaii, nearly 60 bridges have been identified as potentially scour critical based on observed or anticipated conditions at the bridges. The Hawaii Department of Transportation (DOT) is preparing a Plan of Action (POA) for each bridge

Delineation and Classification of Prairie Pothole Wetlands Using GIS and Aerial Photos

Autor: Richard L. Voigt, A. Jake Gusman, Selena M. Forman

Publikováno v: Wetlands Engineering & River Restoration 2001.

The prairie pothole region of North America, encompassing parts of North and South Dakota, Minnesota, Montana, Iowa, and the Canadian prairie provinces, is characterized by numerous shallow wetland depressions. For decades, many of these glacially-cr
