Download or read book Evaporation and Evapotranspiration written by Wossenu Abtew and published by Springer Science & Business Media. This book was released on 2012-08-28 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a thorough presentation of theoretical and applied aspects of the evaporation and evapotranspiration process supported by data from experimental studies. It is written in a way that the theoretical background of evaporation and evapotranspiration estimation is presented in a simplified manner, comprehensive to most technical readers. The book deals with details of meteorological parameters and monitoring sensors which are needed for estimating evaporation and evapotranspiration. Errors in meteorological parameter measurements are also presented. Estimation errors, strengths, weaknesses and applicability of a wide range of evaporation and evapotranspiration estimation methods are presented along with samples of application to a certain region. Application of newer simpler methods is presented. A new technology, remote sensing application to evaporation and evapotranspiration estimation, is presented. The latest interest in the subject, climate change and evapotranspiration is presented in the last chapter. This book will be beneficial to students, hydrologists, engineers, meteorologists, water managers and others.

This book was released on 2000 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of an experiment in which 8 different methods of estimating actual evaporation and transpiration were compared using a common database. Methods based on field data, hydrological models, and satellite data were used and the objectives were to compare results and to assess the utility of each method for various applications.

This book was released on 2017-05-24 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evapotranspiration is the largest outgoing water flux from the Earth's surface; its accurate quantification is critical for the crop development in conditions of the climate changes from recent decades, and it can contribute to a greater understanding of a range of agricultural ecosystem processes. To evaluate the hydric requirements of the crops, it was agreed that they should be reported to a maximum global evapotranspiration called potential evapotranspiration. To estimate this variable, a variety of methods were developed, each with its benefits as well as trade-offs. Their use, however, is laborious due to their complexity and of the large number of parameters required. In this book, specialists' concerns worldwide to develop simple but reliable methodologies - with less data requirement - which will give accurate and appropriate results - are presented. In addition, a study of the physics of the moisture evaporation process from porous media to elucidate what are the mechanisms of moisture migration from granular biopesticides is presented in the last chapter.

Available in PDF, EPUB and Kindle. Book excerpt: This edition of Evapotranspiration - Remote Sensing and Modeling contains 23 chapters related to the modeling and simulation of evapotranspiration (ET) and remote sensing-based energy balance determination of ET. These areas are at the forefront of technologies that quantify the highly spatial ET from the Earth's surface. The topics describe mechanics of ET simulation from partially vegetated surfaces and stomatal conductance behavior of natural and agricultural ecosystems. Estimation methods that use weather based methods, soil water balance, the Complementary Relationship, the Hargreaves and other temperature-radiation based methods, and Fuzzy-Probabilistic calculations are described. A critical review describes methods used in hydrological models. Applications describe ET patterns in alpine catchments, under water shortage, for irrigated systems, under climate change, and for grasslands and pastures. Remote sensing based approaches include Landsat and MODIS satellite-based energy balance, and the common process models SEBAL, METRIC and S-SEBS. Recommended guidelines for applying operational satellite-based energy balance models and for overcoming common challenges are made.

Download or read book Evapotranspiration and complimentarity relations in the water balance of the Volta Basin Field measurements and GIS based regional estimates written by and published by Cuvillier Verlag. This book was released on 2004-09-20 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study concerns evapotranspiration, which accounts for 90% of the water balance in West Africa. At field level, crop and bare-soil albedo measurements were used to build simple models based on phenology, zenith angle and soil surface conditions. Interactions between tree water flux and environmental variables were examined. The complementarity Advection-Aridity (AA) relationship model adequately simulates the spatio-temporal distribution of regional ET rates. The monsoon clouds, harmattan and seasonal changes in surface albedo influence evapotranspiration processes in the Volta Basin. The good performance of the improved AA model indicates its utility for providing independent estimates of ET. These results are valuable input to eco?hydrology and climate models.
