IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Integrated stormwater management in coastal cities
Investigation and assessment of the effects of tidal actions on stormwater outfalls of urban areas in the vicinity of coasts
and shorelines are of great importance. It may be shown that due to independence of pluvial and tidal conditions for the
majority of the cases, stochastic and probabilistic approaches should be resorted to. Combination of urban events return
periods with those of the tidal conditions may be addressed through joint probability approaches. A toolbox has been
proposed here whereby initially, urban runoff modeling would be performed using the EPA SWMM model. This is a widely
used program for simulating urban runoff quantity and quality with the capability of simulating the water depth and flood
volume as well as time of flooding above the urban drainage systems nodes. The combined effects of tidal interaction with
these parameters may then be assessed for varying individual events through a joint probability approach. Effects of land
use change and the resulting social and economic as well as quality/environmental implications may then be investigated
through scenarios generation and their subsequent ranking by multi criteria decision making (MCDM) tools. The proposed
toolbox has been utilised for assessment and design of a storwater system for the city of Bandar-Abbas, center of the Iranian
province of Hormozgan, by the Persian Gulf. Results indicate that the proposed tool may be ideally utilisd for planning and
decision making under varying scenarios vis a vis socioeconomic, environmental and land use implications.
