Dr. Wallace is the head of the Computational Science and Engineering Division within the Information Technology Laboratory at the US Army Engineer and Research Development Center. He leads a team of over 80 federal engineers, computer scientists and technicians in developing state of the art software solutions to support the US Army Corps of Engineers, the Department of Defense and other federal agencies.
Rating curves are necessary to transform the continuous measurement of a stage at a gauge to a discharge. These rating curves based on measured stage and discharge values usually up to bankfull stage. Therefore, the higher area of the rating curves must be extrapolated and have uncertainties. Two-dimensional modeling can close these information gaps.
Prof. Dr.-Ing. Alpaslan Yörük studied civil engineering at the RWTH Aachen University (1996 – 2003). Following he did his PhD at the University of Federal Armed Forces Munich (2003 - 2008) with the issue Uncertainties in numerical simulation of flood plains. 2008 - 2015 he worked for the consulting engineers Hydrotec Ingenieurgesellschaft für Wasser und Umwelt mbH (Hydrotec). In 2015 he became a professor of civil engineering hydraulics at the htw saar and partner in Hydrotec.
The Federal Highway Administration (FHWA) has promoted the use of two-dimensional (2D) modeling for floodplain and bridge hydraulic analysis for many years, and in recent years adopted the US Bureau of Reclamation (USBR) SRH-2D model, due to its advanced modeling capabilities. FHWA also sponsored the development of a custom graphical user interface in the SMS software package, which has a free community version available. The SRH-2D model and custom interface provide powerful tools for analyzing complex hydraulics and clearly communicating results to other disciplines and stakeholders.
This presentation will provide an overview FHWA’s efforts to promote the use of SRH-2D, its capabilities and detail why FHWA is recommending SRH-2D as one of the tools in every engineer’s toolbox for modeling detailed hydraulics around bridges and other structures.
Veronica Ghelardi is a registered Professional Engineer in Colorado and has 19 years of experience in hydrology and hydraulics with a MS in Water Resources from the University of Maryland. Ms. Ghelardi currently works for the Federal Highway Administration’s (FHWA) Resource Center Hydraulics Technical Service Team as a senior hydraulic engineer. She is involved in numerous activities including technology deployment, technical assistance to State DOTs, and training. Prior to this position, Ms. Ghelardi served as the Central Federal Land’s (CFL) Hydraulics Team Lead and the Federal Lands Hydraulics Discipline Champion. In her six years with CFL, Ms. Ghelardi worked in 14 western states performing hydrology, 1-dimensional and 2-dimensional hydraulic analysis for bridges, culverts, low water crossings and other hydraulic structures. Ms. Ghelardi started her hydraulics engineering career with Maryland State Highway Administration in the Structural Hydraulics Unit.
Imagine if you could find out what the flow would be in any river reach in any watershed anywhere in the world for free a couple weeks in advance? Or to develop a 35-year daily flow time series for that location? And all that as a free service on any smartphone, tablet, or computer! Think of the benefits to watershed/water resources planning, operating dams, irrigation systems and other water infrastructure, improving disaster preparedness and climate adaptation, and improving services in trans-boundary watersheds! This is especially important in the context of very few (if any) public-domain online operational services for forecasting flows in most developing countries. This presentation will present an exciting new initiative of the Group on Earth Observations (GEO) Global Water Sustainability (GEOGLOWS) to develop a free, operational service to do exactly this at a global level by building on ongoing initiatives and operationally using disruptive technologies like big data and cloud computing.
Dr. Nelson is a Professor of Civil & Environmental Engineering at Brigham Young University in Provo, Utah. He has been a pioneer in developing geospatial hydrologic modeling and hydroinformatics tools and is the principal developer of the Watershed Modeling System (WMS) which since the mid-90s has been widely disseminated and used for development of hydrologic models and visualization of results. In recent years he and his colleagues at BYU have developed free and open source tools that lower the barrier for engineers to create web-applications for water resources modeling and big-data management and visualizations. These tools have been a foundational element of the NASA-SERVIR Applied Science Team (AST) project that he leads and are being expanded upon in the NASA ROSES (A.50) GEO program to be more collaborative and easier to share amongst scientists and end users solving similar data management, modeling, and visualization challenges.
