This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Middle Rio Grande River (MRGR) is the main source of fresh water for the state of New Mexico. Located in an arid area with scarce local water resources, this has led to extensive diversions of river water to supply the high demand from municipalities and irrigated agricultural activities. The extensive water diversions over the last few decades have affected the composition of the native riparian vegetation by decreasing the area of cottonwood and coyote willow and increasing the spread of invasive species such as Tamarisk and Russian Olives, harmful to the river system, due to their high transpiration rates, which affect the river aquatic system. The need to study the river hydrological processes and their relation with its health is important to preserve the river ecosystem. To be able to do that a detailed vegetation map was produced using a Utah State University airborne remote sensing system for 286 km of river reach. Also a groundwater model was built in ArcGIS environment which has the ability to estimate soil water potential in the root zone and above the modeled water table. The Modified Penman-Monteith empirical equation was used in the ArcGIS environment to estimate riparian vegetation ET, taking advantage of the detailed vegetation map and spatial soil water potential layers. Vegetation water use per linear river reach was estimated to help decision makers to better manage and release the amount of water that keeps a sound river ecosystem and to support agricultural activities.
Download or read book Mapping Riparian Vegetation on the Gila National Forest Using Photogrammetric Techniques written by and published by . This book was released on 2016 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technique for generating a digital surface model (DSM) from stereo 30 cm image pairs was investigated for use in mapping riparian vegetation, canopy cover, and canopy height on the Gila National Forest. Semi-Global Matching (SGM) is a relatively low cost photogrammetric technique used to create a high resolution DSM over a large area using stereo image pairs. For this pilot project, multiple digital elevation model manipulation techniques were used on an image-derived DSM to create a digital terrain model (DTM). The difference between a DSM and a DTM was used to produce a canopy height model (CHM) which was used in mapping land cover, canopy cover, and canopy height. A visual assessment of the CHM, using high resolution imagery, showed agreement with riparian land cover types. The CHM, topographic data, and high resolution imagery were used to segment the study area into objects with similar characteristics for use in vegetation mapping. The effect of the CHM on out-of-bag error in Random Forest classification of vegetation type and canopy height was examined. Generally the largest and smallest canopy height classes were mapped with the least amount of out-of-bag error, and inclusion of the CHM improved the out-of-bag error for the vegetation type map. Possible factors contributing to the results are discussed, including inherent limitations of the SGM technique and challenges related to the terrain of the study area.
Download or read book Bathymetric and Vegetation Mapping Using an Airborne Multispectral Imager written by and published by . This book was released on 1995 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigators collected data over Horsefly River, British Columbia, using the Compact Airborne Spectrographic Imager (CASI) to map riverine and riparian vegetation as well as river substrates. This document examines the applicability of using airborne multispectral imagery to map river bathymetry, substrate materials, and emergent/submergent vegetation. The document describes the data collection instrumentation and methods, depth calibration methods, and classification of aquatic vegetation. It concludes with recommendations for using CASI in an operational airborne remote sensing bathymetry project.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Available in PDF, EPUB and Kindle. Book excerpt: "This sourcebook is intended to assist environmental managers and others who work with indicators in pursuing appropriate methods for indicator testing and production, and to offer some guidance to those responsible for the interpretation of indicators and implementation of decisions based on them. Upon reading this document, technical advisers, environmental policy makers, and remote sensing lab directors and project managers should be able to identify specific, relevant uses of remote sensing data for biodiversity monitoring and indicator development related to the CBD." --p. 8.
