Book Description
L'estudi de les pràctiques d'hidràulica agrària desenvolupades durant l'Edat Mitjana ha mostrat que no ens trobem davant fenòmens purament «etnogràfics» o solucions universals sense valor històric. En aquesta obra col·lectiva s'ofereixen, d'una banda, treballs representatius de regions on s'inicia l'expansió agrària en el marc de la cristal·lització del sistema feudal (Catalunya Vella, Llenguadoc, Borgonya) i, per un altre, diversos estudis sobre les transformacions produïdes en territori conquistats durant els segles XII (regió de Terol, vall del Segre), XIII (regne de València) i finals del XV (regne de Granada). A través de tots ells s'examina la diversitat de mitjans geogràfics (humits i àrids) on es despleguen tècniques hidràuliques aplicades al cultiu, els prats i la molineria.

Book Description
Open-Channel Hydraulics, originally published in 1959, deals with the design for flow in open channels and their related structures. Covering both theory and practice, it attempts to bridge the gap that generally exists between the two. Theory is introduced first and is then applied to design problems. In many cases the application of theory is illustrated with practical examples. Theory is frequently simplified by adopting theoretically less rigorous treatments with sound concepts, by avoiding use of advanced mathematical manipulations, or by replacing such manipulations with practical numerical procedures. To facilitate understanding of the subject matter, the treatment is mostly based on the condition of one- or two-dimensional flow. The book deals mainly with American practice but also includes related information from many countries throughout the world. Material is divided into five main sections for an orderly and logical treatment of the subject: Basic Principles. Uniform Flow, Varied Flow, Rapidly Varied Flow, and Unsteady Flow. There are 67 illustrative examples, 282 illustrations, 319 problems, and 810 references. This classic textbook was the first English-language book on the subject in two decades. Open-Channel Hydraulics is a valuable text for students of engineering mechanics. hydraulics. civil. agricultural. sanitary. and mechanical engineering, and a helpful compendium for practicing engineers. Dr. Ven Te Chow was a Professor of Hydraulic Engineering and led the hydraulic engineering research and teaching programs at the University of Illinois. Through many years of experience as a teacher, engineer, researcher, writer. lecturer, and consultant, he became an internationally recognized leader in the fields of hydraulics, hydrology and hydraulic engineering. Dr. Ven Te Chow authored two technical books and more than 60 articles and papers in scientific an engineering magazines and journals. He was a member of lAHR, ASCE, AGU, AAAS, SEE, and Sigma Xi, and had been Chairman of the American Geophysical Union's Permanent Research Committee on Runoff.

Book Description
As dams age, they are subject to a series of external agents and processes which tend to deteriorate the qualities with which they were originally conceived to stand against these actions. At the same time, it is often necessary to respond to increased safety standards, either in the structural or hydrological fields. Reservoir sedimentation or wat

Book Description
During the life of a dam, changes in safety standards, legislation and land use will inevitably occur, and functional deterioration may also appear. To meet these challenges, these Proceedings from a panel of international experts assess, define and re-evaluate the design criteria for the construction of dams and the many attendant issues in on-going maintenance and management. Authors include international specialists: academics, professionals and those in local government, utilities and suppliers. Practitioners from these same fields will find the book a useful tool in acquiring a comprehensive knowledge of managing and retrofitting dams, so that they can continue to meet society's needs.
