FMA Challenge 1 (1D-2D linked)
Introduction
If you haven't already completed the tutorial models, please see this tutorial model page. This page is for TUFLOW users of intermediate to advanced caliber.
In this challenge, a fully two-dimensional model with a nested one dimensional model will be developed to explore an Urban Riverine conditions with an urbanized overbank floodplain. The model includes several hydraulic structures/bridges within the main stream system which will impact flood elevations. Flooding within the urbanized overbank floodplain is expected.
From this challenge, it is expected the user will develop their skills in:
- Nested 1D/2D models;
- Understanding Urban Riverine conditions and overbank floodplains,
- Understanding of the influence of hydraulic structures;
- Using scenarios and variables to determine a suitable cell size, timestep and log output scenarios; and
- Using bc layers with HX, XP, CD and CN types altogether.
Data for this model is provided via ZIP compressed file posted on the internet/FTP for download.
Data Notes
The original data for this analysis has been modified from its original datum and original elevations have been altered and corrupted such that the data would not be usable for real world modeling, analysis and mapping. Datum data has been stripped from the files provided. A combination of statute (ft) and metric (m) data is provided in the challenge data. Analysis may be performed in metric or Statute units, however all returned data shall be delivered to FMA in Statute (ft) units. Additionally, some of the provided data indicates vertical Datums 29 and 88. We have verified all data provided is in the same vertical datum and for this model challenge assume that is the vertical datum “FMA 12”.
