Water management in the North Deschutes unit irrigation district : geographic perspectives and remote sensing applications

Creator:: Nellis, M. Duane
Abstract:: The North Unit irrigation District of Central Oregon, a water project developed under the guidelines of the Bureau of Reclamation, is characterized by limited water and the need for efficient utilization and control of the irrigation system. To manage the limited water resource, irrigators need a timely and economical method...

Identification of irrigation practices using photographic and optical-mechanical scanning remote sensing techniques

Creator:: Naim, Shamim
Abstract:: Irrigation is essential for profitable agriculture in the western United States. It is the largest consumer of water and power in Oregon. Conflicting uses of water and power and their scarcity demands judicious planning for allocation of these resources. Creditable baseline data are not only needed for irrigated crop acreages,...

The use of remote sensing in an integrated approach for stress detection on the cultivated cranberry

Creator:: Thoma, Michael N.
Abstract:: Remote sensing is an attractive method for the detection and monitoring of crop stress. The feasibility of using remote sensing for the detection and monitoring of fungal diseases, insects, weeds, and non-infectious diseases affecting the cultivated cranberry (Vaccinium macrocarpon Ait.) is evaluated. A study on the fungal disease twig blight...

Airborne videography as a classification and validation technique for Landsat TM-based vegetation mapping

Creator:: Barrett, Charley, 1965-
Abstract:: The Oregon Department of Fish and Wildlife's (ODFW) Ecological Analysis Center (EAC) is in the process of creating, from Landsat Thematic Mapper (TM) imagery, a vegetation map of Oregon that will meet the latest standards set by the National Gap Analysis Program. Since field verification is often expensive and by...

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

A global scale analysis of the spatiotemporal distribution of foliar biomass for 1988

Creator:: Pross, Derek D.
Abstract:: Many ecological systems follow a seasonal cycle affecting primary production,carbon flux, and vegetative gas emissions. The seasonal variation of ecological systems are both affected by and have effects upon climatic factors. A quantitative estimate of the seasonal variation of vegetation is required to characterize ecological systems and their interaction with...

Monitoring individual particle transport in a gravel bedded stream using a passive radio transponder system, Corvallis, Oregon

Creator:: Childers, Elayne S.
Abstract:: 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,...

Mapping vegetation density and water inundation in a recovering wetland : the Mesopotamian Marshlands

Creator:: Bosley, Jon Michael
Abstract:: Once considered the largest wetland in Central Asia, the Mesopotamian Marshlands of Southeastern Iraq have nearly disappeared. Various hydrological projects by the Iraqi government and dam construction in the region have nearly destroyed these once rich freshwater wetlands by over 90%. With the launching of Operation Iraqi Freedom recent attempts...

An evaluation of the resources of the Mosquitia Region of Honduras by means of Remote Sensing and GIS

Creator:: Torres, Juan Carlos
Abstract:: The Mosquitia Region of Honduras is part of the largest wilderness area in Central America. In terms of biodiversity the area is rich in ecosystems including pine savannas, tropical rain forests, and wetlands. These ecosystems are rich in millions of species including rare and endangered. Honduras faces an economic, social,...

Multi-spatial scale representation of landscape transitions using landsat thematic mapper data and scale-space filters

Creator:: Lindeman, Dale R.
Abstract:: This thesis considered current approaches to describing landscape pattern, identified scale issues associated with defining objects, and explored techniques to reliably group elements based on land cover as represented by satellite imagery. It was recognized that there is an important need to develop tools that can be applied using remotely...
