Example: Working with models from CLI#
HydroMT has the following high-level functionality from the Command Line Interface (CLI) for setting up models from raw data or adjusting models:
building a model: building a model from scratch.
updating a model: adding or changing model components of an existing model.
clipping a model: changing the spatial domain of an existing model (e.g. select subbasins from a larger model).
Here we show how to build and update a hypothetical distributed model from the command line interface (CLI) based on the generic HydroMT grid_model.
Lets first check which models are available in our environment:
[1]:
!hydromt --models
model plugins:
generic models (hydromt 0.10.0):
- grid_model
- vector_model
- mesh_model
- network_model
Build a model from CLI#
To build a model you always follow the next four steps.
Prepare or use a pre-defined data catalog with all the required data sources
Define your model region, see the overview of model region options.
Prepare a model configuration which describes the complete pipeline to build your model, see preparing a model configuration.
Build you model using the CLI or Python interface
Here we focus steps 2-4 and use data from the predefined artifact_data data catalog
Using the hydromt build method we can setup a complete model from scratch. Let’s get an overview of the method and its arguments.
Note the required MODEL
(i.e. name of the model), MODEL_ROOT
(i.e. folder where to save the model) arguments. As of version v0.7.0 the REGION
(i.e. area of interest) argument is optional. This argument can be used by adding -r or –region flag.
[2]:
!hydromt build --help
Usage: hydromt build [OPTIONS] MODEL MODEL_ROOT
Build models from scratch.
Example usage: --------------
To build a wflow model for a subbasin using a point coordinates snapped to
cells with upstream area >= 50 km2 hydromt build wflow /path/to/model_root
-i /path/to/wflow_config.yml -r "{'subbasin': [-7.24, 62.09], 'uparea':
50}" -d deltares_data -d /path/to/data_catalog.yml -v
To build a sfincs model based on a bbox hydromt build sfincs
/path/to/model_root -i /path/to/sfincs_config.yml -r "{'bbox':
[4.6891,52.9750,4.9576,53.1994]}" -d /path/to/data_catalog.yml -v
Options:
--opt TEXT Method specific keyword arguments, see the method
documentation of the specific model for more
information about the arguments.
-i, --config PATH Path to hydroMT configuration file, for the model
specific implementation.
-r, --region TEXT Set the region for which to build the model, e.g.
{'subbasin': [-7.24, 62.09]}

The example above means the following: run hydromt build with:
grid_model
: i.e. build a generic GridModel instance./tmp_grid_model
: output model folder--region "{'bbox': [11.70, 45.35, 12.95, 46.70]}"
: set the region of interest using a bounding box defined by its [xmin, ymin, xmax, ymax] coordinates (in WGS84)--opt "setup_grid.res" = 0.05
: choose the resolution of the grid to generate within the bounding box. Unit (degree or meter) depends on the chosen coordinate system.-vv
: give some extra verbosity (2 * v) to display feedback on screen. Now debug messages are provided.
As we did not specify a hydromt configuration, besides the hydromt.log file, an empty model simulation configuration file, only the model region (area of interest) and the grid definition have been defined and are respectively saved in the geoms folder and the grid.nc file. To build a complete model we need the use a hydromt configuration .yaml file.
[4]:
# print MODEL_ROOT folder
import os
def print_dir(root):
for path, _, files in os.walk(root):
print(path)
for name in files:
if name.endswith(".xml"):
continue
print(f" - {name}")
print_dir("tmp_grid_model")
tmp_grid_model
- hydromt.log
- model.ini
tmp_grid_model/grid
- grid.nc
tmp_grid_model/geoms
- region.geojson
The configuration file exists of available setup_methods for your model, listed in the order of execution. Most methods start with reading input data using the DataAdapter, transforming the data using workflows (e.g. reprojection, reclassification, aggregation, etc…) and adding the new model data to the right model component. An overview of the available methods can be found in the online API reference for the GridModel, VectorModel, and MeshModel
Note that these methods for the generic model classes are still quite limited. To get an idea of potential setup_ methods, checkout the model plugins
The configuration yaml file can be passed to the hydromt build method using the -i
flag.
[5]:
# check the content of the .yaml file (for sake of the example only)
fn_yaml = "grid_model_build.yaml"
with open(fn_yaml, "r") as f:
txt = f.read()
print(txt)

In this configuration, you see that we will prepare quite a lot of data for our grid model using some of the generic model methods for grid. We will prepare:
A grid with constant values 0.01 using setup_grid_from_constant
A couple of grid based on reprojection of MERIT Hydro IHU (elevation, basins) and VITO (landuse) using setup_grid_from_rasterdataset. Note that to use the same method twice within the same configuration file, you can end the method name with a number.
A grid generated by mapping roughness values to the land use classes in VITO using setup_grid_from_raster_reclass
A couple of lake properties including the fraction of the grid cells covered by the lake geometry using setup_grid_from_geodataframe

The example above means the following: run hydromt build with:
grid_model
: i.e. build a generic GridModel instance./tmp_grid_model1
: output model folder-r "{'bbox': [11.70, 45.35, 12.95, 46.70]}"
: set the region of interest using a bounding box defined by its [xmin, ymin, xmax, ymax] coordinates (in WGS84)-i grid_model_build.yaml
: use this .yaml file to configure the model build-d artifact_data -d data/vito_reclass.yml
: parse the pre-defined artifact_data and the local vito_reclass data catalogs-vv
: give some extra verbosity (2 * v) to display feedback on screen. Now debug messages are provided.

Update a model from CLI#
Using the hydromt update method we can update an existing model with new components or modify existing components. Let’s get an overview of the method and its arguments.
Note that the MODEL
(i.e. name of the model), and MODEL_ROOT
(i.e. folder of existing model) are still required. There is an optional -o --model-out
option to save the updated model in a different directory.
[11]:
!hydromt update --help
Usage: hydromt update [OPTIONS] MODEL MODEL_ROOT
Update a specific component of a model.
Set an output directory to copy the edited model to a new folder, otherwise
maps are overwritten.
Example usage: --------------
Update (overwrite!) landuse-landcover based maps in a Wflow model: hydromt
update wflow /path/to/model_root -c setup_lulcmaps --opt lulc_fn=vito -d
/path/to/data_catalog.yml -v
Update Wflow model components outlined in an .yml configuration file and
write the model to a directory: hydromt update wflow /path/to/model_root -o
/path/to/model_out -i /path/to/wflow_config.yml -d
/path/to/data_catalog.yml -v
Options:
-o, --model-out DIRECTORY Output model folder. Maps in MODEL_ROOT are
overwritten if left empty.
-i, --config PATH Path to hydroMT configuration file, for the model
specific implementation.
-c, --components TEXT Model methods from configuration file to run
--opt TEXT Method specific keyword arguments, see the method
documentation of the specific model for more
information about the arguments.
-d, --data TEXT Path to local yaml data catalog file OR name of
predefined data catalog.
--dd, --deltares-data Flag: Shortcut to add the "deltares_data" catalog
--fo, --force-overwrite Flag: If provided overwrite existing model files
--cache Flag: If provided cache tiled rasterdatasets
-q, --quiet Decrease verbosity.
-v, --verbose Increase verbosity.
--help Show this message and exit.
In this basic example we use the hydromt update method to update the GridModel instance with an upstream area raster map. Then we write only the updated model map component to file.
The %%writefile
magic saves the content below to a file. The content of the .yaml file start from the second line.

%%writefile ./tmp_grid_model1/grid_model_update.yaml
