A GIS/Simulation Framework for Assessing Change in Water Yield over Large Spatial Scales

Description: Recent legislation to,initiate vegetation management in the Central Sierra hydrologic region of California includes a focus on corresponding changes in water yield. This served as the impetus for developing a combined geographic information system (GIS) and simulation assessment framework. Using the existing vegetation density condition, together with proposed rules for thinning to reduce fire risk, a set of simulation model inputs were generated for examining the impact of the thinning scenari… more

An Automated Land Analysis System (ALAS) for applications at a range of spatial scales: Watershed to global

Description: Recent advances in Digital Elevation Model (DEM) data availability and topographic analysis have enabled us to develop an Automated Land Analysis System (ALAS). ALAS is based on a series of codes which determine topographic and hydrologic characteristics at each pixel, watershed, and each large scale cell. The input requirements are a DEM from any location in the world, it`s resolution, and array size. A Motif accessed script reads in these inputs and generates a series of data sets which furth… more

Measurement of methyl-tert-butyl-ether (MTBE) in raw drinking water

Description: In order to assess the pathways for human exposure to methyl-tert-butyl-ether (MTBE) and to understand the extent of MTBE contamination in watersheds, a purge and trap gas chromatographic mass spectrometric method to measure part-per-trillion (ppt) concentrations of MTBE in environmental waters was developed. A variety of California's raw drinking waters were analyzed. No detectable MTBE was found in deep groundwater (>1000 feet). However shallow groundwater ({approx}250 feet) contained MTBE… more

TERRAIN: A computer program to process digital elevation models for modeling surface flow

Description: This document provides a step by step procedure, TERRAIN, for processing digital elevation models to calculate overland flow paths, watershed boundaries, slope, and aspect. The algorithms incorporated into TERRAIN have been used at two different geographic scales: first for small research watersheds where surface wetness measurements are made, and second for regional water modeling for entire counties. For small areas methods based on flow distribution may be more desirable, especially if time-… more

Developing integrated technical approaches to characterize ecosystem sustainability : watershed, ground-water basin, and wetlands perspectives.

Description: This paper presents the challenge, goals, and general approach for quantifying and measuring ecosystem sustainability, including human components, from a hydrologic system perspective. These integrated, multidisciplinary approaches and tools are used to identify the key environmental functions and structures (physical and hydrobiogeochemical) at the wetlands, watershed, and ground-water basin scale that can be, applied in ecosystem characterization and socioeconomic analysis.

Yakima River Species Interactions Studies Annual Report: 1990

Description: Studies of species interactions were implemented to address concerns about the possible effects of supplementation (with anadromous species) on resident fish populations in the upper Yakima River basin. The current study objectives include collection of baseline information on the fish populations in the upper Yakima River and associated tributaries. As part of this baseline phase, spawning surveys of the upper Yakima River and thirteen selected tributaries between Roza and Keechelus dams were … more

Interpretation of Geological Correlation Borings 1, 2, 3 in the A/M Area of the Savannah River Site, South Carolina

Description: The Geophysical Correlation Boring (GCB) Program was organized to provide a comprehensive correlation capability between geological core and advanced borehole geophysical data, surface high resolution reflection seismic information and, when available, borehole geochemical and cone penetrometer data. This report provides results and initial geological interpretations of borings one, two, and three (GCB-1, GCB-2, GCB-3) located within the Upper Three Runs Watershed (A/M Area) of the Savannah Riv… more

Alternative methods to determine headwater benefits

Description: In 1992, the Federal Energy Regulatory Commission (FERC) began using a Flow Duration Analysis (FDA) methodology to assess headwater benefits in river basins where use of the Headwater Benefits Energy Gains (HWBEG) model may not result in significant improvements in modeling accuracy. The purpose of this study is to validate the accuracy and appropriateness of the FDA method for determining energy gains in less complex basins. This report presents the results of Oak Ridge National Laboratory`s (… more

Evaluation of Water Quality Conditions Near Proposed Fish Production Sites Associated with the Yakima Fisheries Project, 1991-1993 Final Report.

Description: In 1991, the Pacific Northwest Laboratory (PNL) began studying water quality at several sites in the Yakima River Basin for the Bonneville Power Administration. These sites were being proposed as locations for fish culture facilities as part of the Yakima Fisheries Project (YFP). Surface water quality parameters near the proposed fish culture facilities are currently suitable for fish production. Water quality conditions in the mainstream Yakima River and its tributaries are generally excellent… more

Biomonitoring of fish communities, using the Index of Biotic Integrity (IBI) in Rabbit Creek-Cat Creek Watershed, Summer 1992

Description: The Index of Biotic Integrity (IBI) is a method for evaluating the health of water bodies and watersheds by analyzing sample catches of fishes. Sites are scored on a numerical scale of 12--60 and on that basis assigned to a ``bioclass`` ranging from ``very poor`` to ``excellent.`` Overall, the major causes of depressed IBI scores in the Rabbit Creek watershed would appear to be: Organic pollution, mostly from livestock, but also from agricultural runoff and possible septic tank failures; sedime… more

Biomonitoring of fish communities, using the index of Biotic Integrity, as an indicator of the success of soil conservation measures in the Rabbit Creek and Middle Creek watersheds, Macon County, North Carolina

Description: Fish communities in two upper Little Tennessee River tributaries, Rabbit Creek and Middle Creek, both located in Macon County, North Carolina, were monitored using IBI methods in 1990 and again in 1992. A single site, each on the lower reaches of its respective creek, was chosen to reflect the influence of conditions throughout the watershed and to provide a measure of water quality exiting the watershed. The Rabbit Creek watershed (Holly Springs community) has a long history of settlement and … more
