This session provides an overview of the case studies and presents the expectations outlined by Team 2. The project focuses on the development of a flood model using HEC-RAS, a widely recognized tool for hydrological and hydraulic simulations. Furthermore, the methodology for the upcoming sessions is presented, providing a structured approach to ensure systematic progress and the achievement of project objectives.
This initiative represents a collaborative effort, aimed at integrating interdisciplinary expertise to address complex flood modelling challenges.
Week 1 will focus on the main steps of data preprocessing for the flood model. This session will cover the preparation of key input data to ensure precise and efficient modeling in HEC-RAS. The primary tool required for this session is QGIS, which will be used for spatial data manipulation and preprocessing tasks.
The input data required for this session is available for download at the link below:

Week 2 will focus on the estimation of river geometry parameters and the correction of the DEM to improve the river network. This session is the second part of the HEC-RAS input data preparation process.

Week 3 will focus on the calculation of bankfull discharge and rainfall scenarios. This session is the last part of the HEC-RAS input data preparation process. https://www.dropbox.com/scl/fo/zzq9dnp6b6mr01di8dgvo/AIXDFc7xAG4oWoRQJIl9x9k?rlkey=8fot3p9o0lkht4d0qlo2dzbtl&st=tcjvxn9y&dl=0

Week 4 will focus on constructing the HEC-RAS model using the outputs from previous sessions. Key topics include unsteady flow simulations, result interpretation, model calibration, and inundation model development.

In addition, the complete input data to build the model, including the outputs generated in earlier sessions, can be accessed via the link below:

Week 5 will focus on reviewing the progress of your HEC-RAS model and addressing any challenges encountered. Dedicated Q&A sessions will be available to provide guidance and support.
Week 6 will focus on correcting the rainfall data by adjusting the duration from 6 hours to 24 hours, applying a 2-year discharge as a boundary condition for the current climate scenarios, and refining the mesh around the river.
Week 7 will focus on resolving the issues encountered with the results by reviewing the model setup, identifying the sources of error, and making necessary adjustments to improve accuracy.
Week 8 will focus on learning how to create the digital terrain model and land cover configuration for climate adaptation berms and infiltration basins, as well as performing infiltration calculations based on the new climate adaptation inputs.
Week 9 will focus on discussing the corrected placement of climate adaptation structures and exploring additional climate adaptation measures that can be applied within the model.
Week 10 will focus on the correct assignment of infiltration parameters, including curve numbers, infiltration rates, and abstraction ratios for climate adaptation structures, as well as post-processing to subtract rain garden depths from the resulting flood model.
Rain garden depth substracted formula for Raster Calculator:
("rain_garden_depths" > 0) * max(("flood_depth_map" - "rain_garden_depths"), 0) + ("rain_garden_depths" = 0) * "flood_depth_map"
Week 11 will focus on the proper configuration of the sediment transport module within HEC-RAS, including the implementation of various sediment transport methods and the development of a bed degradation layer to accurately simulate channel evolution under dynamic hydraulic conditions.
