Characteristics of Flood-Producing Rainstorms in the Midwest
At the Midwestern Climate Center, a comprehensive re-evaluation and updating of heavy rainstorm frequency relations for 9 Midwestern states is in progress. A special effort is being made...

A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...

Climate Change and Resulting Hydrologic Response: Illinois River Basin
In the last 20 years, the northern half of the Illinois River basin has been experiencing a wetter and cooler climate. This climate change has significantly increased Illinois River flows...

Impact of Urbanization on Main Stream Flooding
The methodology, results and management implications of a stormwater study at an urban watershed experiencing increasing episodes of flooding along the main channel and flood plain are...

Rangeland Evaluation of WEPP Hydrology
The hydrology component of the Water Erosion Prediction Project (WEPP) utilizes the W.H. Green and G.A. Ampt infiltration equation to simulate the rate and volume of excess rainfall. Excess...

Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...

Chaotic Characteristics of Snowmelt Runoff: A Preliminary Study
Chaos, the study of nonlinear dynamic systems, offers a way of observing order in systems previously thought to be random. In this study, we analyze snowmelt runoff from a small watershed...

Possible Climate Change and Its Impact on Snowmelt and Water Supply in California
Global climate modelers are forecasting relatively large future climate change, with warming of 2 to 5?C. These changes, if they do occur, would have major impacts on California's...

Snow Fencing to Increase Streamflow on Rangelands
Snow deposition and water yield were increased 55% and 127% respectively, and duration of surface runoff was lengthened 17 days in response to snow fencing a sagebrush-covered watershed...

Application of RUSLE to Rangelands
The Universal Soil Loss Equation (USLE) has been revised to more accurately estimate soil loss from both crop and rangeland areas. Major revisions affecting rangeland soil loss estimates...

Simulating Runoff and Sediment Yield on Semiarid Watersheds
This paper describes a computer program called WESP (Watershed Erosion Simulation Program), a physically-based, distributed parameter, event-oriented, one-dimensional numerical model for...

Assessing Nonpoint Pollution Potential of Surface Waters Using a Geographic Information System
The use of Geographic Information Systems (GIS) to determine the susceptibility of surface waters to nonpoint pollution is described. The Geographic Resources Analysis Support System (GRASS)...

Utility of a GIS in Watershed Management?A Case Study
A geographic information system data base was established for a small watershed in Shelby County, Tennessee, for both surface and subsurface water attributes. The surface water portion...

Environmental Compliance and River Maintenance on Santo Domingo Pueblo, New Mexico
River maintenance activities within the boundaries of the Santo Domingo Pueblo on the Rio Grande have departed from the traditional channelization philosophy and employed engineering methodologies...

Effects of Water Erosion Processes on Drainage and Irrigation Systems
This study examines the relationship between geomorphic processes and drainage/irrigation projects. It illustrates the method of geomorphic analysis by the study of a drainage project...

A Comparison of Runoff and Sediment Yields from Bare and Vegetated Plots Using Rainfall Simulation
Data from 108 small plot rainfall simulator experiments on pinyon-juniper woodlands in Arizona and New Mexico were analyzed to determine quantifiable effects of cover on hydrologic and...

Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delware in order to assess the effects of watershed drainage projects on...

Effects of Forest Cover on a Snowpack in the Sierra Nevada
Adjacent snowpacks in a clearing and under a forest canopy were compared over a decade at a site near Lake Tahoe. This comparison provides a few indications of the differences in snowpack...

An Interactive Computer Model to Simulate Water Quality of Streamflow from Forested Watersheds in Arizona
To better formulate water resources policies and management strategies, a computer model that simulates concentrations of dissolved chemicals in snowmelt-runoff from forested watersheds...

Predicting Overland Flow Response: Effects of Spatially-Varying Soil Properties
A physically-based model of Horton overland flow is applied to experimental data from a simulated rainfall event in eastern Washington. The model employs the Green-Ampt infiltration equation...
