This book was released on 2013-03-09 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nutrient dynamics and biological structure of shallow non-stratified lakes differ markedly from that of deep and stratified lakes: for example, the return of nutrients lost through sedimentation is faster and the potential importance of fish and submerged macrophytes as food-web regulators is greater. In addition shallow lakes are more easily influenced by fluctuations in the physical environment caused by wind disturbance, temperature change, etc. Although shallow lakes are often the most common lake type in lowland countries, less attention has been paid to them than to deep stratified lakes and few comparisons have been made between shallow freshwater and brackish lakes. The volume is divided into five main themes, each introduced by an invited speaker: Nutrient dynamics with special emphasis on sediment water interactions and changes in loading (Professor Lambertus Lyklema); Biological structure and trophic interaction (Professor Stephen T. Threlkeld); Submerged macrophytes: dynamics and role in the lake ecosystems (Ass. Professor Kaj Sand Jensen); Comparison of freshwater and brackish lake ecosystems (Professor Brian Moss); Modelling the impact of nutrients, the biological structure and the recovery process (Dr Marten Scheffer).

Book excerpt: The perceptibly changing climate has resulted in more precipitation in a small number of short periods. As most urban water management systems were developed at a time when precipitation was distributed more evenly throughout the year, they cannot deal properly with the new circumstances, and high groundwater levels and excess water are the result.

This book was released on 1998-05-31 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication is a classic example of a problem that requires a multi-disciplinary, multi-sectorial and multi-focal approach for its solution. Over time many surface waters have become overloaded with nutrients with dire ecological consequences. Initial attempts to tackle excessive algal growths in lakes by crude chemical treatments were superseded by strategies that began to attack what was believed to be the source of the problems: excessive phosphorus in wastewater. Today it is widely accepted that eutrophication is a highly complex phenomenon that can be averted or abated by holistic approaches. The development of a more thorough understanding of eutrophication and of practicable measures to combat it have been prime concerns in the distinguished career of Professor Lambertus Lijklema. It is thus most appropriate that to pay tribute to him on his retirement leading experts from the world of eutrophication research should gather to review our knowledge of all aspects of the phenomenon. The 27 papers selected for these proceedings examine the science of the processes involved and of the whole system, the ecological effects, modelling studies, and the policies and management measures that are being successfully applied. These proceedings will be an exceedingly valuable publication for all those engaged with the problem of eutrophication.

Available in PDF, EPUB and Kindle. Book excerpt: This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.
