Configuration Files

Floodwater uses a series of YAML configuration files to define how the system will operate. These files are designed to be re-used so that only minimal changes are required to reuse files for different suites.

The required configuration files are:

• Suite Configuration File - This defines the basic operation of the suite, i.e. the name of the suite, which options will be turned on and off, the locations of other files, and the model geometries to be used.

• Credentials File - This file defines the credentials used to access parts of the system which are.

• System Configuration File - This file defines the information that is specific to a particular system. This includes the location of any executables that are necessary as well as the type of queueing system.

There are some configuration files which are optional:

• APSViz Configuration File - This file optionally defines how to interact with the APSViz system

• FloodID Configuration File - This file optionally defines how to interact with the FloodID system

All YAML configuration files are validated against a schema, which will throw errors if it is not adhered to.

Additionally, there is a json configuration file that is specific to each model geometry that is used within the system. This file is used to define specific model settings used within each specific model, and can range from the physics implementations to the locations of boundary conditions which should be used.

                  depends:
                      - <list of strings> (optional)

A minimal ADCIRC configuration would look like this:

adcirc:
    geometry: /path/to/geometry

This very simple configuration would run the ADCIRC model with default settings for the meteorological domain, though this is rarely what you would want. A more complete configuration would look like this:

adcirc:
    geometry: /path/to/geometry
    meteo_domain: [ -98.0, 25.0, -88.0, 31.0 ]
    meteo_resolution: 0.10

Full ADCIRC configuration options

The complete list of options for the ADCIRC model are described below. There are many optional parameters which can be edited and updated as the user sees fit.

• geometry

  The path to the ADCIRC geometry file. This is a required parameter

• geometry_name (optional)

  The name of the geometry. This is used in the case that a user wants to override the name specified in the model configuration file

• waves

  A boolean value which indicates whether or not to run the wave model (SWAN)

• meteo_domain (optional)

  A list of floats which defines the domain of the meteorological forcing. The order of the list is [min_lon, min_lat, max_lon, max_lat]

• meteo_resolution (optional)

  The resolution of the meteorological forcing in degrees

• meteo_background_domain (optional)

  A list of floats which defines the domain of the meteorological background forcing. The order of the list is [min_lon, min_lat, max_lon, max_lat]. This will be used in the case that your configuration has multiple types of forcing, i.e. HWRF on top of GFS

• meteo_background_resolution (optional)

  The resolution of the meteorological background forcing in degrees

• station_file (optional)

  The path to the station file. This is a file which contains a list of stations which will be used to extract time series data from the ADCIRC output

• output (optional)

  These keys control the different output options within the ADCIRC model. By default, most output is turned on.

• postprocessing / forecast (optional)

  A dictionary which defines the postprocessing options for the ADCIRC model and which phase of simulation they will run for. The plots option is a boolean value which indicates whether or not to run the plotting scripts for the ADCIRC model using FigureGen. These have a moderate value for rapid QAQC, but are not necessary for the operation of the system. The scripts dictionary allows the user to execute an arbitrary script at the end of the simulation. This is useful for one-off items which are not necessary to include within the Floodwater system as a whole. The user can provide the name of the script, the path to the script, and any arguments that should be passed to the script. The duration parameter is the expected duration of the script so it can be monitored by the system.

HEC-RAS

The HEC-RAS model is an optional model which can be run in addition to the ADCIRC model. It is not required for the operation of the system. HEC-RAS can be forced at its boundary with water levels from the ADCIRC model and wind and pressure data from the specified meteorological source. Currently, the model must consists only of a single 2D domain. It is expected that future iterations of the system will support the use of multiple 2D domains. Additionally, the system is configured and tested for HEC-RAS 6.1. The system is unlikely to work with versions prior to 6.1 and it is unknown if the system works with versions later than 6.1.

hecras:
    geometry: <string>
    geometry_name: <string> (optional)
    meteo_domain: <list of floats> (optional)
    meteo_resolution: <float> (optional)
    postprocessing: (optional)
        analysis:
            raster: <bool>
        forecast:
            raster: <bool>
        raster_topography: <string>
        raster_resolution: <float>
        raster_bounding_box: <list of floats>

A minimal HEC-RAS configuration would look like this:

hecras:
    geometry: /path/to/geometry

This very simple configuration would run the HEC-RAS model with default settings for the meteorological domain, though this is rarely what you would want. A more complete configuration would look like this:

hecras:
    geometry: /path/to/geometry
    meteo_domain: [ -98.0, 25.0, -88.0, 31.0 ]
    meteo_resolution: 0.10

  A list of floats which defines the domain of the meteorological forcing. The order of the list is [min_lon, min_lat, max_lon, max_lat]

• meteo_resolution (optional)

  The resolution of the meteorological forcing in degrees

• postprocessing / forecast (optional)

  The postprocessing options center around computing a peak water surface elevation raster, which is used for display on the web interfaces that the system connects to. The raster option is a boolean value which indicates whether or not to run the raster generation scripts for the HEC-RAS model. Additionally, since HEC-RAS uses a subgrid methodology, to generate meaningful water level information, the user must supply a raster so that the wet/dry mask can be computed. The user will also need to supply information about where the raster should be created and at what resolution.

SFINCS

The SFINCS model is an optional model which can be run in addition to the ADCIRC model. It is not required for the operation of the system. SFINCS can be forced at its boundary with water levels from the ADCIRC model and wind and pressure data from the specified meteorological source.

sfincs:
    geometry: <string>
    geometry_name: <string> (optional)
    meteo_domain: <list of floats> (optional)
    meteo_resolution: <float> (optional)

A minimal SFINCS configuration would look like this:

sfincs:
    geometry: /path/to/geometry

This very simple configuration would run the SFINCS model with default settings for the meteorological domain, though this is rarely what you would want. A more complete configuration would look like this:

sfincs:
    geometry: /path/to/geometry
    meteo_domain: [ -98.0, 25.0, -88.0, 31.0 ]
    meteo_resolution: 0.10

• meteo_resolution (optional)

  The resolution of the meteorological forcing in degrees

XBeach-1D

The XBeach-1D model is an optional model which can be run in addition to the ADCIRC model. It is not required for the operation of the system. XBeach-1D can be forced at the transect starting locations with water levels and wave information from the ADCIRC+SWAN model. The simulations are run in parallel, with each transect being run on a separate core.

xbeach-1d:
    geometry: <string>
    geometry_name: <string> (optional)
    transect_selection_method:
        proximity:
            x: <float>
            y: <float>
            radius: <float>
            wave_height: <float> (optional)
            wave_period: <float> (optional)
        conditions:
            wave_height: <float> (optional)
            wave_period: <float> (optional)

A minimal XBeach-1D configuration would look like this:

xbeach-1d:
    geometry: /path/to/geometry

This very simple configuration would run the XBeach-1D model with default settings for the transect selection method. A more complete configuration would look like this:

xbeach-1d:
    geometry: /path/to/geometry
    transect_selection_method:
        proximity:
            x: -97.0
            y: 28.0
            radius: 0.5
            wave_height: 0.5

This would select transects within 0.5 degrees of the point (-97.0, 28.0) and would only select transects which have a wave height of at least 0.5 meters.

Full XBeach-1D configuration options

The complete list of options for the XBeach-1D model are described below.

• geometry

  The path to the XBeach-1D geometry file. This is a required parameter

• geometry_name (optional)

  The name of the geometry. This is used in the case that a user wants to override the name specified in the model configuration file

• transect_selection_method

  The transect selection method can be either proximity or conditions. The proximity method selects transects based on their proximity to a point and the conditions method selects transects based on their conditions. The proximity method requires the user to specify the x and y coordinates of the point and the radius of the circle around the point. The conditions method requires the user to specify the wave height that the transect must have in order to be selected.

Full FloodID Configuration Options

The complete list of options for the FloodID configuration file are described below.

• enabled

  A boolean value which indicates whether or not to enable the FloodID service

• models

  A list of models to use. The keys within this dictionary are:

  • name

    The name of the model

  • type

    The type of the model. This can be one of the following:

    • adcirc

    • sfincs

  • mesh_file (optional)

    The path to the mesh file. This is used to define the mesh for the model. Used only for ADCIRC.

  • raster

    A dictionary which defines the raster options for the model. The keys within this dictionary are:

    • domain

      A list of floats which defines the domain of the raster. The order of the list is [min_lon, min_lat, max_lon, max_lat]

    • resolution

      The resolution of the raster in degrees

    • dem (optional)

      The path to the digital elevation model file. This is used to define the elevation of the raster used in downscaling. Used only for SFINCS.

  • stations (optional)

    The path to the stations file. This is used to define the stations for the model.

  • project_codes

    A dictionary which defines the project codes to use for the model. The keys within this dictionary are:

    • model_results

      A list of project codes to use for the model results

    • dashboards

      A list of project codes to use for the dashboards

The stations file for FloodID uses the following format:

- service: <string>
  id: <string>
  index: <int> or [int, int]
- service: <string>
  id: <string>
  index: <int> or [int, int]
- service: <string>
  id: <string>
  index: <int> or [int, int]

The index value is used to provide information to the FloodID user interface as to which location in the model corresponds to the station. The index value may not always be the nearest location within the model, so it is best to allow the user to specify this manually as they’d always be able to find a nearest station and supply it if they’d prefer. The index can be either a single value (i.e. for ADCIRC or HEC-RAS) or a pair of values representing the i, j indices for a gridded model (i.e. for SFINCS). The full description of the stations file is below:

• service

  The service to use for the station. This can be one of the following:

  • usgs

  • noaa

  • ndbc

• id

  The id of the station. This is the station id used by the service

• index

  The index of the station. This is the index of the station within the model. This can be either a single value (i.e. ADCIRC, HEC-RAS) or a pair of values for a gridded model (i.e. SFINCS)

Model Geometry Configuration Files

ADCIRC

The ADCIRC configuration file is used to set the parameters used within the model, including model time step, nodal attributes included in the model, physics settings, boundary conditions, and model geometry name. The file is ALWAYS named config.json and resides in a folder which contains the raw model files and any prepared decompositions.

Mesh decomposition is typically a process that is a nontrivial time consideration. The script floodwater_adcirc_generate_prepdir, which is installed with the system, can generate a pre-packaged decomposition archive automatically. The output from this script should be stored alongside the other files in this mesh data directory. It will be named something like decomp001023.tar.gz. Note that the number of cores provided should be the number of compute cores, not the total number of cores (i.e. including writier processors).

{
    "name": "mesh_name",
    "dt": 2.0,
    "attributes": [
        "surface_submergence_state",
        "surface_canopy_coefficient",
        "mannings_n_at_sea_flood",
        "sea_surface_height_above_geoid"
    ],
    "physics": {
        "preset": "standard"
    },
    "usgs_flow_stations": [
        "none",

    "tide_boundary": {
        "Q1": [ "amplitude", "phase" ],
        "O1": [ "amplitude", "phase" ]
    }
}

The list of valid tide constituent names can be computed using the following:

import numpy
import utide
valid_tides = []
invalid_tides = []
[valid_tides.append(name) if ~numpy.isnan(amp) else invalid_tides.append(name) for name,amp,freq in zip(utide.ut_constants["const"]["name"], utide.ut_constants["const"]["doodsonamp"], utide.ut_constants["const"]["freq"])]

valid_tides = ['SA', 'SSA', 'MM', 'MSF', 'MF', 'ALP1', '2Q1', 'SIG1', 'Q1', 'RHO1', 'O1', 'TAU1', 'BET1', 'NO1', 'CHI1', 'PI1', 'P1', 'S1', 'K1', 'PSI1', 'THE1', 'J1', 'OO1', 'UPS1', 'OQ2', 'EPS2', '2N2', 'MU2', 'N2', 'NU2', 'GAM2', 'H1', 'M2', 'H2', 'LDA2', 'L2', 'T2', 'S2', 'R2', 'K2', 'ETA2', 'M3']

}

XBeach-1D

The XBeach-1D configuration file is used to set the parameters used within the model, including the locations of the transects that should be used. Since XBeach requires multiple input files per transect, they are organized in a directory structure as follows:

[transect_directory]
├── T0001
│   ├── T0001_bedfric.txt
│   ├── T0001_info.txt
│   ├── T0001_XYdata.txt
│   ├── x_file_tnsct_0001.txt
│   └── y_file_tnsct_0001.txt
├── T0002
│   ├── T0002_bedfric.txt
│   ├── T0002_info.txt
│   ├── T0002_XYdata.txt
│   ├── x_file_tnsct_0002.txt
│   └── y_file_tnsct_0002.txt

Transects are numbered with an integer identifier. They do not need to be sequential, but they must be unique.

The config.json file that is used for the model will look like:

{
    "name": "model_name",
    "offshore_locations": "/path/to/offshore_locations.txt",
    "transect_directory": "/path/to/transect_directory"
}

The offshore_locations file is a text file which contains a list of the offshore locations where boundary condition information is extracted. These should be in WGS84 coordinates. The file should look like:

3    #...Point Count
1 -97.0 28.0
2 -97.1 28.1
3 -97.2 28.2

Next, the info file contains some of the metrics of importance for the transect. The file should look like:

T_ID    1
