Available in PDF, EPUB and Kindle. Book excerpt: In regions where groundwater is used for irrigation, significant water losses take place due to evaporation. Previous studies demonstrated the utility of stable oxygen and hydrogen isotopes in estimating evaporative water loss experienced during return flow back to an aquifer. Unlike arid regions where the other studies took place, this study examined the region around Kalamazoo, Michigan, the United States, which experiences a more temperate climate. Irrigation in the Kalamazoo area primarily uses center-pivot systems supplied by wells, unlike flood irrigation in previous study areas. Water samples were taken periodically from wells close to center-pivot irrigation systems. Water losses due to evaporation were estimated using stable oxygen and hydrogen isotopes, which are effective tracers for water. This approach was possible in the Kalamazoo area since the distribution of oxygen and hydrogen isotopes in local precipitation, which is the source of groundwater recharge, is known based on years of measurements. Isotope analyses during the irrigation season suggest water loss due to evaporation is approximately 14.3%. This is less than what was estimated by previous studies in arid climate zones. Evaporative water loss was greater at wells near cornfields than at wells that supplied other crop types. There was little expected correlation between the groundwater’s isotope ratio values and the change in chloride concentration. This is likely due to an external input of chloride from road salt used in winter months.

Download or read book Evaporation of Water With Emphasis on Applications and Measurements written by Frank E. Jones and published by CRC Press. This book was released on 2018-01-31 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of water from lakes, rivers, oceans, vegetation, and the earth, as well as man-made structures such as reservoirs and irrigation conduits, is a major concern of hydrologists and irrigation specialists. This loss, compounded by the lack of usable water in some areas, indicates a need for field and laboratory research that will contribute to the understanding of the processes and parameters that comprise and contribute to evaporation.This book emphasizes the process of the air-water interface and discusses such important topics as evaporation and condensation coefficients of water, heat and mass transfer, surface temperature, interfacial tension, convection, diffusion, thermal gradients, wind-generated waves, and the roles that these processes play in evaporation. The book also discusses subjects such as methods for suppressing evaporation using films, water vapor distribution, wind tunnel investigations, evaporation from water drops, preparation of pure water, molecular diffusion, the eddy-correlation method, and evaporation estimation methods. The book will be of considerable value to hydrologists, irrigation specialists, meteorologists, civil engineers, chemical engineers, hydraulic engineers, water resources specialists, water conservation specialists, geophysicists, environmental engineers, and anyone interested in understanding the evaporation of water and its consequences.

This book was released on 2013 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Water is the lifeblood of Idaho agricultural practices. Under future climate, water shortages may occur and better water management will need to occur under these conditions. The role of irrigation under a changing climate has not been previously investigated in the Snake River Basin. Irrigation schemes implemented in the NOAH Land Surface Model are tested within the Weather Research and Forecast Model 3.4 at 4-km resolution. The goals of this research are to investigate the effect of irrigation-induced cooling on local and regional climate in Southern Idaho, under present and future climate projections, and to diagnose irrigation-induced changes to surface energy fluxes and characteristics of boundary-layer meteorology. The control run versus irrigated run analysis, from 2010-2012, revealed irrigation induced cooling of the 2-meter temperature via evaporation, a decrease of the average growing season planetary boundary layer height and increase in the average growing season 2-meter dewpoint over the cropland (irrigated) grid-cells. The study reveals future trends in irrigation and evaporation based on dynamical downscaling of two global climate models from 2040-2045 and 2040-2070. With a better understanding of the evapotranspiration in southern Idaho, water can be better managed through all users in Idaho in drought conditions and in a changing climate."--Boise State University ScholarWorks.
