An analysis of the distribution of precipitation and runoff from the historical record for the continental United States

Dolph, Jayne Ellen (1990-10-25)

Characterizing the distribution of precipitation at regional scales is a requirement for the development of regional scale, spatially distributed hydrologic water balance models. This study performs a preliminary asse ...
The application of spatial data analysis and visualization in the development of landscape indicators to assess stream conditions

Buckley, Aileen R. (1997-09-15)

The main theme of this research is the application of geographic techniques in a study involving environmental monitoring and analysis of the associations between landscape and in-stream characteristics in the Pacific No ...
Comparing intercell distance and cell wall midpoint criteria for discrete global grid systems

Gregory, Matthew Jay (1999-06-01)

Many diverse applications have begun to study processes and patterns at a global scale. To aid in this research, discrete global grid systems (DGGSs) are data models which enable environmental modeling, monitoring and ...
The conceptual development and use of ecoregion classifications

Brewer, Isaac (1999-05-06)

This thesis explores the genesis of the ecoregion concept, examines the conceptual development of ecoregion classification systems, investigates applications of ecoregion classification systems for a broad range of pu ...
Detecting changes in a wetland : using multi-spectral and temporal Landsat in the Upper Noun Valley Drainage Basin-Cameroon

Ndzeidze, Stephen Koghan (2008-10-13)

Since the early 1980s, satellite imagery has been commonly used to detect change in wetlands. The overall objective of this study is to utilize remote sensing and Geographic Information Systems (GIS) technology to dete ...
Effects of scale properties on biodiversity mapping in Oregon

Kennelly, Patrick J., (Patrick Joseph) (1997-10-25)

The effect of scale is an important concern in mapping of biodiversity. Scale issues include the grid cell size used for analysis and the effect of the extent and internal boundaries. Because biodiversity analysis involv ...
Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of Southern Oregon and Northern California : a Geographic Information System approach

Zanger, Christopher (2007-03-06)

Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must ...
Protected-area effectiveness near dynamic colonization zones: forest clearance in and around Amboró National Park, Bolivia

Bucklin, David N. (2010-06-15)

Protected natural areas are important reserves for biodiversity, and in the tropics, often play a role in deterring deforestation. This paper evaluates the effectiveness of a protected-area with a two-tiered management ...
