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
From this challenge, it is expected the user will develop their skills in:<br>
*Nested 1D/2D models;
*Understanding Urban Riverine conditions and
*Understanding of the influence of hydraulic structures;
*Using scenarios and variables to determine a suitable cell size, timestep and log output scenarios; and

= 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”.

Line 22 ⟶ 23:
*Several stream photographs and structure photographs are available in the data. Several data sets are also provided to assist the modeler in determining model parameters.
*A starting set of overland N-Values is provided in the land use data set, however, the modeler can modify these as needed.
*Terrain data is provided in elevation contours. Depending on the system the modeler will use to create terrain data for their model, the modelers may need to add supplemental break line data to these contours to obtain a more accurate model in the
*The modeler is to assume that the terrain data provided represents the ground conditions at the time the runoff event occurs, and that the ground conditions will not change during the event. Terrain data is provided in DEM data file formats.
*The Inflow Hydrograph for the main stream and tributary are provided in the EXCEL spreadsheet contained in the '''INFLOWS''' directory. The inflows are referenced to CHAINAGE locations along the creek (matching survey cross section CHAINAGE).
