Continuum

Continuum (Silvestro et al., 2013) is a continuous distributed hydrological model that strongly relies on a morphological approach, based on a novel way for the drainage network component identification (Giannoni et al., 2005). The model is a compromise between models with a strong empirical connotation, which are easy to implement but far from reality, and complex physically based models which try to reproduce the hydrological processes with high detail but which introduce a hard parameterization and consequent uncertainty and lack of robust parameter identification. For information about the Continuum model see http://www.cimafoundation.org/wp-content/uploads/doc/CONTINUUM_english.pdf

Continuum model adapter

Continuum pre-adapter

Model pre-adapter for running Continuum model from CIMA Foundation.

Usage: python continuum_preadapter.py <netcdf run file pathname relative to current working directory>

Properties

 

domain_name

(required)

String representing the name of the model domain. This string is used to build output filenames and retrieve domain information files.

time_resolution

(required)

Output time resolution in hours.

 

Notes for users

  • For all files that are written by this adapter, if the file to be written already exists, then it will be overwritten.

  • This program prints log messages on screen.

  • This program uses the information in the specified netcdf run file as input and uses this information to do the following actions:

    1. Converts 2d data fields from the netcdf file to Continuum input binary files.

    2. Create the Continuum configuration file by filling the provided template file. The template is filled with the data according to the table below

 

 

domaindir

domain working directory relative path

domain

domain name

input_data_dir

input data directory relative path

numberofsections

number of hydrological sections for the output

DEMLLLat, DEMLLLon, DEMCellSize, DEMNRows, DEMNCols

Georeference information for the DEM files

METEOLLLat, METEOLLLon, METEOCellSize, METEONRows, METEONCols

Georeference information for the Continuum input files

RainfallDuration

length (hours) of the input dataset

StartDate

Start date string

EndDate

End date string

 

System requirements

  • This program needs Python 2.7 or higher.

  • This program needs the following Python modules:

    • netCDF4

Continuum post-adapter

Model post-adapter for running Continuum model from CIMA Foundation.

Usage: python continuum_postadapter.py  <netcdf run file pathname relative to current working directory>

Notes for users

  • For all files that are written by this adapter, if the file to be written already exists, then it will be overwritten.

  • This program prints log messages on screen

  • This program uses the information in the specified netcdf run file as input and uses this information to convert the Continuum ascii hydrograph output file to netcdf format.

System requirements

  • This program needs Python 2.7 or higher.

  • This program needs the following Python modules:

    • netCDF4

    • numpy

GeneralAdapterRun Example Configuration

The following gives an example of how to set up the GeneralAdapterRun file for Continuum in FEWS using the model pre and post-adapters.  The GeneralAdapterRun file follows the general structure as described here.

General

In this section general information regarding the module such as version number, file directories, missing values, and time zone information can be specified.

Start-up activities

Clear the model working directory of any previous runs before starting a new run.

 

<startUpActivities>

 <purgeActivity>

   <filter>%ROOT_DIR%/*</filter>

 </purgeActivity>

</startUpActivities>

 

 

Export activities

In this section the data to be exported from FEWS as input to the module is specified. Data to export to Continuum model includes:

  • Input data (air temperature, wind, relative humidity, rainfall, solar radiation)

  • Run file

Note: Input data, on current version, are obtained from an interpolation procedure on the Bocca di Magra domain. This setting is fixed, but should be changed in order to generalize the adapter.

The run file contains information regarding the input file names, start and stop times, and time step. Additional properties can be passed using the run file as listed above under Properties.
