The workshop is part of the IAHS scientific programme for the IUGG Assembly.

Objectives
In many countries around the world a rapid alternation of floods and droughts is observed. A common question which has been posed is whether the change in frequency of hydrological extremes is a result of global warming or lies within the natural variability of climate. For water resources management water quantity aspects were important. But a key concern is the environmental impacts of floods and droughts as a result of rapid change due to different flow conditions. The main purpose of the workshop is to bring together scientists from various fields of research (hydrologists, chemists, etc.) who have experience of interdisciplinary programmes on hydrology and water quality. Scientists who are not currently participating in large programmes but who have an experience in that scientific domain are also welcome. The workshop topics will cover several aspects (1) point sources which will influence water quality (industry, waste water treatment plants, landfills), (2) diffuse sources (agricultural areas, groundwater and sediments), (3) fate and behaviour of pollutants under extreme hydrological conditions and their impact on water quality, (4) mobilisation models for different flow conditions (risk management); (5) Indicator substances (which flow conditions trigger which substances). The workshop will provide an opportunity to closer link the water quantity with the quality community especially with respect to hydrological extremes.
