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.

Quantitative assessment of flood damage reduction projects through physically-based watershed models
ies in the State of Iowa, USA are located in areas prone to flooding and therefore resources are
continuously devoted to reducing flood related damage. Numerical models can help quantify the benefit of proposed
flood mitigation projects and contribute to a more efficient allocation of resources. This study presents results from a
physically-based HUC 12 watershed model. The control-volume finite element model HydroGeoSphere was used.
Computational grids include a highly-detailed representation of the main features of the watershed. Simulations were
used to quantify the impact of flood mitigation projects. For the analyzed window, the model predicts a 4.5% reduction in
peak discharge. Model performance was assessed against data for saturated water content and discharge. A detailed
analysis of the measured data used for model performance assessment is presented in a companion paper entitled
ˇ§Comprehensive analysis of hydrologic processes and nitrate concentrations at the watershed scale based on
continuous monitoring dataˇ¨.Form Required :
