1D HEC RAS Modeling
Your reading for next Thursday will be out of the HEC-RAS documentation and should be a review (in terms of principles), but with slightly different notation for the equations. The reading will focus on how these principles are applied in the 1D hydraulic model HEC-RAS
(Hydrologic Engineering Center
- River Analysis System), which we will use in lab on Thursday.
- From the Brunner (2010a) Reference Manual read the following:
- Skim Chapter 1's 'Overview of Hydraulic Capabilities' on pages 1-2 to 1-3 (pp 12-13 inPDF)
- Thoroughly digest Chapter 2's ('Theoretical Basis for 1D Flow Calculations') section on 'Steady Flow Water Surface Profiles' on pages 2-2 to 2-21 (pp 18-37 in PDF)
- Skim Quickly Chapter 3's (Basic Data Requirements) 'Geometric Data' Pages 3-2 to 3-23 (pp 68-89 in PDF) & 'Steady Flow Data' on pages 3-23 to 3-25 (pp 89-91 in PDF)
- From the Brunner (2010b) User Manual read the following:
- Skim Chapter 3's (Working with HEC-RAS - An Overview) 'Steps in Developing A Hydraulic Model with HEC-RAS' on pages 3-5 to 3-14 (33 xx-43 in PDF)

2D Delft3D Hydraulic Modelling
A simple Matlab script for reading in hydraulic model results in
*.csv format and running a PHABSIM style model. NOTE, the HSCs are hard coded and HSI type is an option.
CHaMP HSM - An access database driven habitat suitability model approach that uses DELFT outputs.
- A simple FIS- based habitat model (in this case for frog habitat), which is driven by *.csv input and can be run using MATLAB's fuzzy logic toolobox
