The investigation and modelling of hydrological processes is a fundamental task to many hydraulic-engineering problems, such as flood risk mitigation, evaluation of water supply potential for hydropower generation, stream-pollution and water-quality management, ecological-flow assessment, evaluation of stream erosivity and sediment transport capacity. The planning of flood risk mitigation measures, the design of river engineering works and the identification of the most suitable strategies for water resources management rely heavily on hydrological studies and predictions. Such projects, as well as other hydraulic engineering applications, consist of complex compounds of interrelated disciplines, of which hydrological investigations represent a component rather than a standalone element.

This session focuses on the synergies and mutual interchanges of knowledge and expertise between hydrology and hydraulic engineering, and serves as a meeting point between researchers from these two areas of the scientific community.

A few possible examples of topics that should be addressed by contributions to this session are:
- reducing the uncertainty of hydrologic predictions through feedbacks from hydraulic engineering;
- contribution of hydrology to environmental issues in river engineering;
- case studies highlighting interrelationships between hydrology and hydraulic engineering.

The session is co-sponsored by the International Association of Hydraulic Engineering and Research (IAHR).
