Riverine Ecosystem Management
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern...
River Science
River Science is a rapidly developing interdisciplinary field at the interface of the natural sciences, engineering and socio-political sciences. It recognises that the sustainable management of contemporary rivers will increasingly require new ways of characterising them to enable engagement with the diverse range of stakeholders. This volume represents the outcome of research by many of the authors and their colleagues over the last 40 years and demonstrates the integral role that River Science now plays in underpinning our understanding of the functioning of natural ecosystems, and how societal demands and historic changes have affected these systems. The book will inform academics, policy makers and society in general of the benefits of healthy functioning riverine systems, and will increase awareness of the wide range of ecosystem goods and services they provide.

A Theory of Aspectuality
Sentences may pertain to states or processes or events. They may express duration, frequency, habituality, and many other forms of temporality. How do they do this? It is the aspectual properties of sentences in natural languages which allow the user to express a temporal structure, and Henk Verkuyl presents a unified formal system to account for them. He explains aspectuality in terms of the opposition between terminative aspect and durative aspect, and describes the way in which terminative aspect is compositionally formed on the basis of semantic information expressed by different syntactic elements, in particular the verb and its arguments. The aim is to determine which semantic conditions make a sentence terminative; but at least ten different forms of durative aspectuality are also treated. All are drawn into a theory which can account for both terminative and durative aspectuality together. A Theory of Aspectuality draws together into a coherent whole the author's thinking on the subject over the last twenty years, and will interest all those working on aspect and the semantics of noun phrases. It promises to be a major new contribution to our understanding of the subject.
Riverine Ecology Volume 2
This book is part of a two-volume set that offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa and their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones. The set provides a considerable volume of research on the biodiversity component of river ecosystems, seasonal dynamics of physical chemical parameters, geo-hydrological properties, types, sources and modes of action of different types of pollution, river restoration strategies and methodologies for the ongoing ecological changes of river ecosystems. Volume 2 highlights bio...
