Book Estimation of Annual Groundwater Evapotranspiration from Phreatophyte Vegetation in the Great Basin Using Remotely Sensed Vegetation Indices and Ground Based Flux Tower Measurements

Beamer and published by . This book was released on 2011 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escalating concerns about the future of water resource management in arid regions of the American Southwest have sparked numerous hydrologic studies looking into available water resources for in-basin and inter-basin transfers. Groundwater is the primary water supply source for much of the state of Nevada and the Great Basin, thus accurate estimates of the regional scale groundwater recharge and discharge components are critical for regional groundwater budgets. Groundwater discharge from phreatophyte vegetation by evapotranspiration (ET) is the dominant component of groundwater discharge in many hydrologically closed valleys of the Great Basin, and can be measured directly from eddy-covariance (EC) and Bowen-ratio (BR) flux tower systems. The purpose of this project was to develop a predictive equation based on relationship between annual ET and meteorological data from EC and BR sites in phreatophyte vegetation with remote sensing data. Annual total ET (ET a) measured from forty site/year combinations of flux tower data from Carson Valley, Walker River Basin, Oasis Valley, Snake Valley, Spring Valley, White River Valley, and the lower Colorado River Flow system were correlated with the Enhanced Vegetation Index (EVI) from Landsat Thematic Mapper (TM) satellite. EVI was extracted from source areas at corresponding locations from 15 mid-summer Landsat TM scenes. ET a was transformed into ET* by subtracting annual precipitation and normalizing by annual reference ET (ET0) (ET*=(ETa -precipitation)/(ET0 -precipitation)). ET* correlated well with EVI (r2 =0.97), and because it takes basin specific climate measurements into account, it is transferable to many shallow groundwater discharge areas in the Great Basin. This relationship was used to provide a first order estimate of the mean annual groundwater ET (ET g) from four phreatophyte groundwater discharge areas in Nevada using only a mid-summer Landsat EVI image, annual ET0 and precipitation data. This simple approach provided estimates of mean annual ETg volumes which compare well with estimates from previous studies from these phreatophyte areas.

Book Hydrogeologic and Hydrochemical Framework South Central Great Basin Nevada California

Download or read book Hydrogeologic and Hydrochemical Framework South Central Great Basin Nevada California written by Isaac Judah Winograd and published by . This book was released on 1975 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purposes of this investigation were to: define the hydraulic character and subsurface distribution of the major aquifers and aquitards; identify and describe the principal areas of recharge to and discharge from the major aquifers; and determine the rate and the direction of ground-water movement within the major aquifers and aquitards. Of these objectives, the third was of prime importance for an evaluation of the rate of movement of various radionuclides from the vicinity of an underground nuclear detonation. The accuracy of the velocity estimates, however, rested heavily upon the other two study objectives. The Nevada Test Site occupies a small part of two ground-water basins - the Ash Meadows and the Oasis Valley-Fortymile Canyon basins. Consequently, the objectives are discussed for a region several times the size of the test site.
