The phenomenon of evaporation in the natural environment is of interest in various diverse disciplines. This book is an attempt to present a coherent and organized introduction to theoretical concepts and relationships useful in analyzing this phe nomenon, and to give an outline of their history and their application. The main objective is to provide a better understanding of evaporation, and to connect some of the approaches and paradigms, that have been developed in different disciplines concerned with this phenomenon. The book is intended for professional scientists and engineers, who are active in hydrology, meteorology, agronomy, oceanography, climatology and related environ mental fields, and who wish to study prevailing concepts on evaporation. At the same time, I hope that the book will be useful to workers in fluid dynamics, who want to become acquainted with applications to an important and interesting natural phenomenon. As suggested in its subtitle, the book consists of three major parts. The first, consisting of Chapters I and 2, gives a general ouline of the problem and a history of the theories of evaporation from ancient times through the end of the nineteenth century. This history is far from exhaustive, but it sket~hes the background and the ideas that led directly to the scientific revolution in Europe and, ultimately, to our present-day knowledge.

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.

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 monograph discusses the essential principles of the evaporationprocess by looking at it at the molecular and atomic level. In the first part methods of statistical physics, physical kinetics andnumerical modeling are outlined including the Maxwell’s distributionfunction, the Boltzmann kinetic equation, the Vlasov approach, and theCUDA technique. The distribution functions of evaporating particles are then defined.Experimental results on the evaporation coefficient and the temperaturejump on the evaporation surface are critically reviewed and compared tothe theory and numerical results presented in previous chapters. The book ends with a chapter devoted to evaporation in differentprocesses, such as boiling and cavitation.This monograph addressesgraduate students and researchers working on phase transitions andrelated fields.

Aid Evaporation is a new Nortion. It is based on an academic study that comprehensively examined how ODA is governed from the source to the destination. Key ODA parameters emerged from the existing ODA governance frameworks namely; mechanism, ideology, development approach and processes. By unpacking elements contributing to aid ineffectiveness through these parameters, exploring the existence of the aid evaporation and examining the key enablers of ODA Evaporatoon, the study discovered supply side factors contributed significantly to Aid ineffectiveness. It exposed different AID Evaporation enablers which play different hidden functions such as ODA Door Openers, Appetixers, Softeners, Sponges, Convertors, Controllers, Distorters as well as Carrot and Stick among others. Key findings revealed that the prevailing perception that aid ineffectiveness was a demand side problem was only part of the story because supply side challenges were probably more responsible for billions of ODA that could not be accounted for. It has recommended the re-writing of the narrative that ODA ineffectiveness is predominantly premised on demand side by incorporating supply side factors. Findings demonstrated that while there were indeed demand side challenges such as bad governance, corruption and lack of strong institutions, there were also supply (donor) side challenges such as over-reliance of donor's own inefficient ODA governance frameworks as well as ODA delivery mechanisms, the entrenchment of bilateral interest in ODA processess and geo- political interests among other factors. In this regard, the study confirmed that the 62% of the ODA that could not be accounted for according to existing literature was either held up in the pipeline or evaporates mostly from the supply side. This finding brought clarity on the weak impact of ODA and corroborated with existing literature on the mystery of unaccounted ODA. While the notion of aid evaporation emerged as an attribution and part of a reflection on the problem of ODA dissipation at the preliminary stage of the literature review, it became the central issue of focus throughout the research investigation which involved substantive field work to bring clarity on the problem. The study has made theoretical and practical contributions to the existing concepts on ODA governance and proposed a new concept, namely the “Supply Baggage Concept”. The new concept should inform the Post Paris era in achieving Aid effectiveness by weding out Evaporation, using the Aid Evaporation Detection Framework proposed in this book.
