This document discusses Rijkswaterstaat's use of modeling systems to help achieve its goals of ensuring dry land, safe transport by water, optimal water supply, and a pleasant living environment. It outlines Rijkswaterstaat's projects that use models, the areas models are applied, and the various modeling systems currently in use. Deltares worked with Rijkswaterstaat on the Next Generation Hydro Software project to develop the D-HYDRO Suite for increased modeling flexibility and efficiency. The presentation describes plans to implement D-HYDRO Suite over five years by building workshops and transitioning models while working towards one integrated national model divided into manageable parts.

8 Deltares vision for Rijkswaterstaat
• More modelling flexibility
• Reduction number of models
• Reduction number of calculation engines
• More efficiency coupling different model systems
• Open soure, benefit from developments elsewhere
• Increase interaction water management organisations
• Efficiency in development costs and maintenance costs

10 Implementation D-HYDRO Suite
• Planning:
– Second half 2015, plan of approach
– First half 2016, execution of the plan
– Second half 2016, start building first model
– Rough estimation, whole proces takes 5 years
• Workshops:
– First workshop, model builders and developers
– Second workshop, Rijkswaterstaat users and consultants
– Third and fourth workshop, focus on special area’s
• Overall vision om Models for Rijkswaterstaat:
– Build one model for the Netherlands
– Divided into manageable models
