This book calls the attention of the scientific community, government organizations and non-government agencies, and the general public, to arguably one of the most important and complex of the world s tropical rainforest regions the greater Panama Canal Watershed. The Rio Chagres basin is the primary source for water to operate the Panama Canal, and also supplies water for electricity generation and potable water for municipal use, but this important national resource is largely unstudied from a scientific standpoint. The broad objective of the book is to characterize and understand the...

From time immemorial the Bengal Delta had been an important maritime des- nation for traders from all parts of the world. The actual location of the port of call varied from time to time in line with the natural hydrographic changes. From the early decades of the second millennium AD, traders from the European con- nent also joined the traders from the Arab countries, who had been the Forerunners in maritime trading with India. Daring traders and fortune seekers from Denmark, Holland, Belgium and England arrived at different ports of call along the Hooghly river. The river had been, in the...

Nonsmooth energy functions govern phenomena which occur frequently in nature and in all areas of life. They constitute a fascinating subject in mathematics and permit the rational understanding of yet unsolved or partially solved questions in mechanics, engineering and economics.
This is the first book to provide a complete and rigorous presentation of the quasidifferentiability approach to nonconvex, possibly nonsmooth, energy functions, of the derivation and study of the corresponding variational expressions in mechanics, engineering and economics, and of their numerical treatment....

It is beyond any doubt that East-Central European countries such as Czech Republic, Hungary, Poland and Slovakia has dramatically changed its shape through its radical transition from centrally planned to the market economies in last 7 years. Many economists divide the process of economic transformation into areas of Stabilization, Liberalization, and Privatization/Restructuring. The traditional view is that stabilization and liberalization can be achieved rather quickly-by balancing budgets, balance of payments, tightening money supply, freeing prices and liberalizing trade-but that the area...

It is the task of the engineer, as of any other professional person, to do everything that is reasonably possible to analyse the difficulties with which his or her client is confronted, and on this basis to design solutions and implement these in practice. The distributed hydrological model is, correspondingly, the means for doing everything that is reasonably possible - of mobilising as much data and testing it with as much knowledge as is economically feasible - for the purpose of analysing problems and of designing and implementing remedial measures in the case of difficulties arising...

This volume presents the core of invited expository lectures given at the 1993 NATO ASI held at the University of York. The subject matter of the ASI was the interplay between automata, semigroups, formal languages and groups. The invited talks were of an introductory nature but at a high level and many reached the cutting edge of research in the area. The lectures were given to a mixed group of students and specialists and were designed to be accessible to a broad audience. The papers were written in a similar spirit in the hope that their readership will be as wide as possible. With one...

The book gives an up-to-date review of the flow features in a hydraulic jump, and its technical applications as an energy dissipator. Based on a vast technical literature, the present ideas are summarised, compared with each other and generalised whenever possible. Particular stress is laid on explaining the basic terms, describing effects of energy dissipation on various neighboring fields and presenting prototype experiences with hydraulic jump dissipators. These structures are also compared with other means of energy dissipation found in dam engineering. As a result civil engineers working...

Arid and semi-arid regions can be defined as environments in which water is the limit ing factor for bio-systems. This means that survival of life in these regions involves a constant struggle to obtain this limited commodity and draw the maximum benefit out of it. However, despite the difficulties for plants, animals, and man to live in, these regions, they are being utilized more and more because of the pressure of world population growth. This is expressed in the expansion of agricultural activities in desert lands as well as by the formation and rapid growth of urban and industrial...
