Chameleon is a physics-based landscape modeling software system designed for modeling and simulations applications. Hyperspectral laboratory, field, and imaging spectrometer measurements are collected as empirical foundation data. Linear spectral unmixing is performed to decompose each image pixel into spectral endmembers. Mathematical manipulation of these fractional abundances and introduction of new...
The John Day Reservoir, a large reservoir between the John Day and the McNary Dams on the Columbia River, must be lowered several feet below design level during salmon migration season in order to preserve anadromous fish habitat. This research assessed the north shore of the John Day Reservoir for...
Field data collection techniques in combination with remote
sensing techniques were used to interpret and map the complex flow pattern of
the numerous glaciers comprising the Juneau lcefield, spanning the Alaska-
Canada boundary range. The extensive nature of the icefield mandated the use
of a variety of methods for surveying...
Gathering empirical data on the factors and processes affecting bedload transport
in the field is difficult. This project conducted during the winter of 1996 field tested a new
passive method of positively tracking individual particle movement. The project was
conducted in Oak Creek, a gravel bedded stream, located in Corvallis,...
The main purpose of this research is
1. To analyze the terrain/climate of Cape Verde, with emphasis on cloud
cover, and its effect upon satellite image acquisition.
2. To use a methodology that allows the use of AutoCAD to map these clouds effect in image acquisition to permit viewing whatever...
Spectral profiles, transformed divergence values, and feature space derived from Landsat Thematic Mapper (TM) data were used to analyze the ability of four false color composites to discriminate between different classes of salt-affected soils. To compare the spatial distribution of salt-affected soil classes, maps were generated for each false color...
The use of Geographic Information Systems (GIS) is rapidly expanding in almost every field of inquiry. The field of Archaeology is also learning to use GIS to improve both initial data collection in the field and data analysis in the lab. This paper evaluates the usefulness of the GIS software...
Much of the rich forestlands of Oregon are subject to frequent mass wasting
events, resulting in severe environmental and economic damages. Extensive research has
shown that this landslide hazard is often exacerbated by many management activities.
Following a severe storm event which triggered thousands of landslides, the Oregon
Department of...
Bangladesh lies almost entirely on the delta of three major rivers: the Padma (the
Ganges), the Jamuna (the Brahmaputra), and the Meghna. A considerable portion of
Bangladesh has been repeatedly devastated by floods associated with cyclonic storm
surges along its coastal islands and riverine flooding along the rivers traversing the...
The Oregon Dunes National Recreation Area is managed by the Siuslaw
Forest division of the United States Forest Service (USFS). This area has gradually been
overcome by vegetation since the 1950's, originating with the exotic European Beach
Grass (Ammophila arenaria). The invasion of this exotic vegetation has resulted in a...
