As water resources engineering continues to integrate with natural systems design and community development, the critical role of hydrologic and hydraulic modelling in predictive analysis continues to add value in the pursuit of sustainability and resiliency. When merged with Geographic Information Systems (GIS), aerial imagery and climatological data, cutting edge modeling and software platforms facilitate advancements water resources and risk management. Through highlighting a variety of hydrologic and hydraulic (H & H) modelling projects, Scott C. Blossom P.E., CFM, LEED AP will explore the benefits of H & H modelling and its role in managing water resources in a variety of settings.

Mr. Blossom will discuss a range of projects including (but not limited to) shoreline stabilization on the Potomac River, the integration of Priority 1 stream restoration and floodplain modelling at the University of Richmond, and detailed H&H modelling of a natural stream system meandering through a 100-year old military base. The presentation will compare and contrast various types of modelling as they relate to design objectives and budgetary constraints and explore the evolution of ‘urban design storms and scenarios’ that are a standard component of today’s water resource engineering profession. 

Hydrologic and hydraulic analysis for resilient design adds value not only through deliverable but also through process. Through the process of analyzing a system and deciding upon design storms and “scenarios” a design team is forced to gain an understanding of the climatic, topographic, and geographic position of a system and consciously partake in predictive decision making. The fields of stream and wetland restoration have complemented the conventional world of floodplain analysis, dam safety and risk management with a forward-thinking approach involving a more detailed consideration of evolution and natural tendency.  As the scientific and academic communities continue to expand collaborative opportunities to mesh academic data gathering with design practice, the engineering community can add value to ecosystem design while also advancing sustainability and resiliency initiatives for improved community safety.
