Remote Sensing and GIS for Nonpoint Source Pollution Analysis in the City of Dallas' Eastern Watersheds

Remote Sensing and GIS for Nonpoint Source Pollution Analysis in the City of Dallas' Eastern Watersheds

Date: June 1989
Creator: University of North Texas. Dept. of Biological Sciences.
Description: This report describes the findings of a study conducted on the Eastern Watersheds of Lake Lavon, Lake Ray Hubbard, Lake Tawakoni, Lake Palestine and Lake Fork, which are located within the Blackland Prairie, Post Oak Savannah and Pineywoods provinces. These watersheds are among nine that provide drinking water to Dallas, Texas. The study examines the potential benefit of "remote sensing and geographic information systems (GIS) for watershed management" in these five watersheds (p. iii).

How Healthy is the Upper Trinity River?: Biological and Water Quality Perspectives

How Healthy is the Upper Trinity River?: Biological and Water Quality Perspectives

Date: 1990
Creator: Jensen, Ric
Description: This conference report contains discussions and papers from a symposium hosted at Texas Christian University, in Fort Worth, Texas, examining the ecological health of the Upper Trinity River, and the impacts of various human activity, such as agriculture, urbanization, and waste management. The papers cover the effect of water quality on urban rivers, long-term water quality trends in the Trinity River, solutions that may improve water quality in the river, as well as biological, agricultural and waste-water issues.

Regional Assessment of Water Quality: Trinity River Basin

Regional Assessment of Water Quality: Trinity River Basin

Date: October 1992
Creator: Alan Plummer and Associates, Inc.
Description: The purpose of this study is "to identify significant issues affecting water quality" within the Trinity River watershed, located in the eastern half of Texas, "and to provide sufficient information for the Commission, river authorities, and other local government bodies to take appropriate corrective action necessary to maintain and improve the quality of [the] state's water resources" (p. [1]).

[Maps and Notes to Accompany an Expedition Narrative]

Date: 1849
Creator: Lynch, William Francis, 1801-1865.
Description: Two maps that accompany a narrative about a U.S. expedition in 1849. The first sketch map is of the area around the Dead Sea (Scale ca. 1:126,720). The second sketch map details the area around the River Jordan (Scale ca. 1:63,360). Each map includes some landmarks of the area and depths including relief shown by hachures. An additional page (front and back) has handwritten notes containing the expense sheet from the expedition.

Past Global Changes (PAGES) Status Report and Implementation Plan

Past Global Changes (PAGES) Status Report and Implementation Plan

Date: 1998
Creator: Oldfield, Frank
Description: This document summarizes progress made thus far by the Past Global Changes (PAGES) programme element of the International Geosphere-Biosphere Programme (IGBP). The document also outlines the implementation plans for most of the Foci, Activities and Tasks currently within the PAGES remit. The plan first introduces the scope and rationale of PAGES science and explains how PAGES is organized structurally and scientifically to achieve its goals. For all of the palaeosciences relevant to IGBP goals, PAGES has sought to identify and create the organizational structures needed to support continued work and progress. Models intended to predict future environmental changes must, in order to demonstrate their effectiveness, be capable of accurately reproducing conditions known to have occurred in the past. Through the organization of coordinated national and international scientific efforts, PAGES seeks to obtain and interpret a variety of palaeoclimatic records and to provide the data essential for the validation of predictive climate models. PAGES activities include integration and intercomparison of ice, ocean and terrestrial palaeorecords and encourages the creation of consistent analytical and data-base methodologies across the palaeosciences. PAGES has already played a crucial role in the archiving, management and dissemination of palaeodata. This is fully summarized in the recently published ...

Land-Ocean Interactions in the Coastal Zone:  Science Plan and Implementation Strategy

Land-Ocean Interactions in the Coastal Zone: Science Plan and Implementation Strategy

Date: 2005
Creator: Land-Ocean Interactions in the Coastal Zone
Description: Coastal zones play a key role in Earth System functioning, by contributing significantly to the life support systems of most societies. Human activities modifying riverine hydrology and riverine material fluxes to the coastal zone, have increased in both scale and rate of change in the last 200 years. The underlying processes that drive changes to coastal systems occur at a multiplicity of temporal and spatial scales. These changes alter the availability of ecosystem goods and services. However, disciplinary fragmentation impedes our ability to understand the regional and global changes that affect coastal systems, and thus limits our ability to guide management and decision making. Progress has been made in understanding the changes in Earth System processes that affect the coastal zone, and the role of coastal systems in global change. This includes identifying proxies that describe the state of coastal systems under existing conditions and change scenarios. Typologies have been developed to assist in the interpolation of results into areas where primary information is lacking. This has enabled a first-order up-scaling to a global synthesis.
