Hydroinformatics systems are systems that combine computational hydraulic modelling with information systems (including knowledge-based systems). They are gaining acceptance in the areas of environmental planning, design and management. This text focuses on sewage systems, starting with their planning and then going on the discuss their design, operation and rehabilitation. The authors discuss business and information needs in the management of urban drainage, tools for collecting and archiving such data, and their use in modelling catchment hydrology, sewer systems hydraulics, wastewater quality, wastewater treatment plant operation, and receiving waters. The control and operation of sewer systems in real time is described, followed by a discussion of their maintenance and rehabilitation. Intelligent decision support systems for managing the urban drainage business process are presented.

In 1997, disastrous flooding running through the Czech Republic, Poland, and Germany took the lives of a great number of people and caused economic damage estimated in tens of billions of dollars. Flooding of the Yangtze river in 1998 killed more than 3000 people, dislocated 230 million souls, and caused direct damage of more than $ 45 billion. Both the general public and the experts are asking what we can learn from these recent events to reduce loss of life and flood damage. The 1997 floods were dealt with by experts from the Czech Republic, Poland and Germany, who presented timely reports on combatting floods, both success stories and shortcomings. This experience is further extended by reports from experts drawn from 13 other countries, developing a broad overview of flood risk management, flood impacts on water quality, human health, and natural ecosystems.

Notwithstanding past achievements, flood damage continues to rise throughout the world as the magnitudes of floods increase, partly as a result of poor land management and partly by climate change, growing populations and continuing development in flood-prone areas, and the aging and deterioration of flood defences. One of the major goals of water management is the protection of society from floods. That issue is addressed here in terms of such broad issues as flood analysis, flood impact, non-structural and structural flood management measures, Non-structural measures focus on flood plain management, flood insurance, flood forecasting and warning, and emergency measures during floods. Structural measures focus on catchment management, embankments and flood reservoirs. Post-flood measures are also discussed. Future planning of flood management should be based on a clear understanding of the effectiveness interventions and their impacts on river catchment ecosystems.

Urban water management issues are particularly important in the countries in transition in Central and Eastern Europe. During the last decade, political, economic and social changes in these countries have influenced almost every element of the public sector, including water services. There is an urgent need for the various countries to exchange information on this issue and to identify the best approaches to achieve this transition. This volume focuses on the acute problems in the field of Urban Water Management in Central and Eastern Europe countries in transition, giving an illustration of the transfer of know-how from traditional NATO countries. The following issues are discussed: wastewater impacts on receiving waters and groundwater; urban drainage planning and management; urban flood protection and management; combined sewer overflow management and control; challenges to urban water supply; wastewater technologies and management; urban river catchment management - case studies; private sector participation in urban water services delivery - case studies; and information technologies in urban water management - case studies (GIS, data management).
