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...
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...
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...
Water Erosion Prediction Project (WEPP) Watershed Model: Hydrologic and Erosion Calculations
The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition...
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...
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...
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...
Hydrologic Effects of Brush to Grass Conversion
A physically based rainfall-runoff model is used to detect hydrologic response to artifically induced vegetation changes on a semiarid watershed. Model parameters are optimized using a...
Watershed Hydrograph Simulation Through Dendritic Channel Networks
In this paper, a linear dendritic simulation model based on the finite difference implicit scheme is presented. In this model, a dendritic matrix solution algorithm for simultaneous solution...
Management Strategies for Baseflow Augmentation
Management strategies for baseflow augmentation fall into the following categories: (1) range management, (2) upland vegetation management, (3) riparian vegetation management, (4) upland...
Precipitation Variability Effects on Modeled Soil Water Deficits
Effective management of forages in steep Appalachian pastures requires an understanding of hydrologic and microclimatic processes on the area. This study was conducted to determine the...
Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...
Summary Report: Evaluation Criteria for Watershed Models
After an extensive literature review, the Task Committee recommends that, in addition to graphical plots, modelers use three simple goodness-of-fit criteria for evaluating continuous hydrograph...
Influence of Tillage on Hydrology in Western Iowa
USDA Agricultural Research Service has operated four field-sized watersheds in the deep loess soils of western Iowa since 1964. Throughout this time, two watersheds were cropped to corn...
Intergovernmental Agreements in Watershed Planning
Management of the surface water system not only rests with state and federal agencies, but more importantly, with local jurisdictions. Recognizing this, a cooperative effort was undertaken...
Maricopa County Hydrology Procedure
The Flood Control District of Maricopa County has developed a procedure to be used for flood hydrology in Maricopa County, Arizona, and the Flood Control District has prepared a Hydrologic...
Rainfall Simulation Studies of Nutrient Export from Watersheds in Arizona and New Mexico
Data from rainfall simulation experiments conducted in Arizona and New Mexico were used to identify relationships between total suspended sediment (TSS) concentrations (kg/ha/mm of runoff)...
AGNPS: A Tool for Watershed Planning
The AGNPS model was developed to provide a means of assessing water quality impacts from agricultural watersheds. AGNPS simulates sediment and nutrient transport from the headwaters to...
Watershed Condition and Riparian Health: Linkages
This paper discusses linkages between riparian areas and their contributing watersheds and how using this knowledge will enhance overall watershed management success. The paper presents...
Watershed Planning in Western Pennsylvania?A Case Study
This paper presents and describes the watershed planning activities being pursued in Allegheny County, Pennsylvania. The regulatory, institutional, and technical framework of the planning...
