The management and organisation of Public Waters requires a deep understanding of the natural and artificial system of flow volumes and the flow pattern of currents, to enable a realistic interpretation of the behaviour of rivers. AMBISAT has conducted many hydrologic and hydraulic studies for this purpose, in basins with very different circumstances and at different scales.

The complexity of these studies is related to the multitude of scientific and technical disciplines involved, from climatological studies to define the design event, through high-resolution mapping, field work, statistical phoronomy studies, hydrometeorological modelling and hydraulic modelling with more advanced programmes.

Some of the work done by AMBISAT is being used to develop the National Flood Mapping and the National Strategy for Restoration of Rivers; both programmes are being promoted by the Ministry of the Environment, Rural and Marine Affairs in order to meet criteria governing the common European policy on these issues, contained in the Flood Directive 2007/60/EC and the Water Framework Directive 2000/60/EC respectively.

This type of study has also been carried out to update Technical Safety Standards for dams and reservoirs, including hydraulic studies of floods caused by breached dams and the detailed study of urban drainage networks that interact with groundwater levels and external run-off.
