Introduction

HEC-RAS 2-D is a two-dimensional hydraulic modeling software developed by the Hydrologic Engineering Center (HEC) of the United States Army Corps of Engineers. The software is used for simulating flow and water surface elevation in river and floodplain systems. HEC-RAS 2-D uses a finite-volume numerical method to solve the Saint-Venant equations, which govern the conservation of mass and momentum in open-channel flow. The software allows for the modeling of complex river systems with combined one- and two-dimensional geometries, bridge and culvert structures, and varying roughness coefficients. HEC-RAS 2-D is widely used in flood hazard mapping, river engineering, and natural resource management.

Course objectives

This advanced HEC-RAS 2-D training course is designed to provide in-depth knowledge and hands-on experience with the software for experienced users. The course covers advanced topics such as unsteady flow modeling, sediment transport, dam-break analysis, and hydraulic structures. Participants will learn how to model complex hydraulic scenarios and analyze the results using advanced visualization techniques. Participants will typically have a strong background in hydraulic modeling and a working knowledge of HEC-RAS 2-D. The course is ideal for engineers, hydrologists, and other professionals who want to expand their expertise in river and floodplain modeling using HEC-RAS 2-D. Upon completion of the course, participants will be able to use the software to simulate and analyze a wide range of hydraulic scenarios with high accuracy and efficiency.

Dr. Maged Aboelata

Dr. Maged Aboelata is a Civil Engineering Manager at Washington Metropolitan Area Transit Authority (WMATA) and an Adjunct Professor at two engineering schools in Washington, DC. With more than 30 years of experience, he participated and directed numerous hydrologic and hydraulic modeling studies for floodplain delineation, flood control, land development, and dam break analysis. His teaching experiences in Water Resources Engineering include Fluid Mechanics, Hydrology and Hydraulics, Advanced Water Resources Engineering, and GIS for Water Resources.

Dr. Aboelata is the author of the initial prototype of HEC-LifeSim, a spatially and temporally distributed model for estimating loss of life resulting from dam breaks and large flood events.  The model was later developed and published by the US Army Corps of Engineers; and used a basis for the simplified version HEC-FIA.

The course is delivered online through our easy-to-use Virtual Campus platform. For this course, a variety of content is provided including:

– eLearning materials
– Videos
– Interactive multimedia content
– Live webinar classes
– Texts and technical articles
– Case studies
– Assignments and evaluation exercises

Students can download the materials and work through the course at their own pace.
We regularly update this course to ensure the latest news and state-of-the-art developments are covered, and your knowledge of the subject is current.

Live webinars form part of our course delivery. These allow students and tutors to go through the course materials, exchange ideas and knowledge, and solve problems together in a virtual classroom setting. Students can also make use of the platform’s forum, a meeting point to interact with tutors and other students.

The tutoring system is managed by email. Students can email the tutor with any questions about the course and the tutor will be happy to help.

This course is designed for Civil and Environmental Engineers involved with floodplain analysis and dam break studies.  Previous experience with one-dimensional hydraulic models is required. Basic knowledge of GIS mapping including map projections and datums for pre- and post-processing is assumed. General knowledge of fluid mechanics and surface water hydraulics will be helpful in understanding the different modeling techniques.

Once a student finishes the course and successfully completes the assignments and evaluation tests, they are sent an accreditation certificate. The certificate is issued by Ingeoexpert to verify that the student has passed the course. It is a digital certificate that is unique and tamper-proof – it is protected by Blockchain technology. This means it is possible for anyone to check that it is an authentic, original document.

You will be able to download the certificate in an electronic format from the Virtual Campus platform. The certificate can be forwarded by email, shared on social networks, and embedded on websites. To see an example, click here.
