Using Modeling to Investigate Impacts of Grass Waterway on Water Quality
Sediment Sorting Near Vegetation Zone Along a Stream
The Evolution of Geosynthetics
Although the geosynthetics industry only began in the 1960s, it roots can be traced to the earliest humans. Soil stabilization, soil reinforcement, liquid drainage and leak proof barrier...

Simulating the Transport of an Algae Bloom off the West Coast of Vancouver Island
Optimum On-Farm Irrigation Efficiency for Sustainable Agriculture
In irrigated agriculture, on-farm irrigation efficiency and salinity build-up in the crop root zone are interrelated. Sustainability of soil productivity and crop production depends on...
Dormant Season Alfalfa Water Balance on the NIIP
Non-growing season water balance parameters were measured for alfalfa under high-elevation desert conditions of the Navajo Indian Irrigation Project in northwest New Mexico. The lysimeters...
Non-Growing Season Water Budgets for a Shortgrass Steppe
The seasonal characteristics of water inputs and outputs during the non growing seasons (October through May) of 1986 to 1992 in a shortgrass steppe are presented in this paper. About...
Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...
An Update on Surface Renewal Estimation of Evapotranspiration
The surface renewal (SR) method for estimating sensible heat flux density (H) has been shown to give good estimates of evapotranspiratiou (ET) when used in an energy balance equation with...
Habitat Preservation and Enhancement Associated with San Diego Creek Flood Control Channel Improvement
San Diego Creek, an important regional flood control channel in southern Orange County, California, flows 2.4 kilometers through the mixed-use areas of Irvine Center (San Diego Freeway...
Drop Structures in the Real World: Guidelines for Drop Structures in Grass Lined and Wetlands Channels
Rehabilitating Arctic Tundra in Alaska
During the past 25 years, there has been significant progress in tundra rehabilitation. Initially, agronomic practices requiring large quantities of grass seed and fertilizer were believed...
The Importance of Plant Community Structure on Form and Function of Created Wetland Systems
If we consider that the creation and the restoration of a wetland system begins with the design of the hydrology, then establishing the form and function of a wetland begins with the design...
Shallow and Surfacing Ground Water in an Arid Urban Environment
Return flow from landscape irrigation is now a major recharge source and the loss of phreatophytic vegetation has caused decreased evapotranspiration discharge in Henderson, Nevada. Lateral...
Vegetative Roughness in Flood Control Channels
Laboratory flume tests and field evaluations were undertaken as a part of the Flood Control Channels Research Program to determine hydraulic roughness values for various types of floodplain...
Simulation of Perilithic Algae as a Biofilm and Its Interaction with the Water Column
A one-dimensional bioflim model has been constructed consisting of a particulate phase of algae and inert material and diffusive transport of nutrients and oxygen. Also included is mass...
Neural Networks Predict Pesticide Leaching
The goal of this work was to determine whether artificial neural networks (ANN) can be used to predict the percentage of applied pesticide that leaches through 50 cm of turfgrass covered...
