River Basin Management is a collection of papers presented at a conference on implementation of the EU Water Framework Directive, held in Budapest in May 2005. The Water Framework Directive requires progressive protection and enhancement to rivers, lakes, estuaries, coastal waters and wetlands by the year 2015. At the heart of this major new piece of legislation is the requirement for all EU member states to prepare river basin management plans for all river basin catchments, providing the basis for coordinated improvements to water management, leading to better water quality and sustainable aquatic environments in lakes and rivers. The papers cover a wide range of topics including pilot studies for the development of river basin management plans, public participation in the planning process, water quality monitoring, modeling and analysis, identifying and addressing pollution and meeting environmental objectives. The book presents an array of experience from eighteen European countries in the implementation of the EU’s most far reaching environmental legislation. It is an invaluable source of information and ideas for the widespread preparation of river basin management plans now starting throughout Europe.

Eutrophication has become one of the major environmental issues of global concern due to the adverse effects on water quality, public health, and ecosystem sustainability. Fundamental research on the restoration of eutrophic freshwaters, i.e., lakes and rivers, is crucial to supporting further evidence-based practical implementations. The 12 published research papers can be classified into to three major aspects of this topic, into which they provide valuable contributions. Firstly, a background investigation into the migration of nutrients and the characteristics of submerged biota will guide and assist understanding of the mechanisms of future restoration. Secondly, various restoration strategies are studied and evaluated, including control of both external and internal nutrient loading. Thirdly, an evaluation of field sites after restoration treatment is reported in order to support the selection of appropriate restoration approaches. We foresee that the papers will significantly contribute to eutrophication control, natural water sustainability, and ecological restoration.
