Understand the basics behind one-dimensional computational hydraulics in order to set up and apply HEC-RAS.
Many aspects of site development, road construction, or other civil projects ultimately involve the computational modeling of the flow of water. The Hydrologic Engineering Center-River Analysis System (HEC-RAS) is a widely used, accepted, and versatile open-channel hydraulics computational modeling software. It is universally approved by federal, state, and local agencies for a wide range of computational hydraulics applications. The steady one-dimensional approach is often used in applying HEC-RAS. You will learn the basics of steady one-dimensional computational hydraulics, including specifics utilized by the HEC-RAS software. It is essential to understand this basic theory of steady one-dimensional computational hydraulics, in order to successfully set up and apply HEC-RAS, and interpret results. You will also learn how to navigate the HEC-RAS user interface, including how GIS information is accessed. The material will tell how to build an HEC-RAS geometry using digital elevation data, how to specify steady flow discharges, how to assign boundary conditions, how to execute a steady flow simulation and view the results. The ability to successfully apply HEC-RAS to model open-channel hydraulics is a skill that continues to be in demand.
