Import from Shapefile

MIKE HYDRO include a comprehensive shapefile conversion feature, enabling import of most georeferenced model objects stored in Shapefiles in to a MIKE HYDRO model.
It is possible to import and define River branches, Water users, Reservoirs, Hydropower features as well as Catchment and Rainfall Runoff method from Shapefiles for the Basin module.
Figure 15.1 presents the dialogue for import of Basin model data from Shapefiles.
Figure 15.1 Import of Basin model features from Shapefile
To import model features from shapefile, do the following:
1. Activate the checkmark in front of the model features that should be imported (multiple features can be imported in one operation).
2. Browse and select the specific shape file using the file selection button '…'.
3. Define feature specific attributes from the shape file using the dropdown menus. Each dropdown menu will present the shape file attributes that are possible to use for the specific MIKE HYDRO feature parameter. Note: It is not required to specify all attributes in drop down menus. If some are left blank, the import utility will just assign default values for these features.
Some attributes in the shape files must be assigned specific numerical values to be recognized and imported correctly by MIKE HYDRO, as some of the features in MIKE HYDRO are defined by a numerical value rather than a string. The table below presents the attribute values for specific feature type definitions used during import from shapefile to MIKE HYDRO.

When selections and filename specifications are complete, press the 'Run' button to execute the import of model data from shapefiles. Press 'Close' to stop the conversion or to close the dialogue.
Note: Reservoirs are attached to river branches in MIKE HYDRO, but imported points (for reservoirs) must not necessarily be strictly superimposed to the imported branches. These objects will be inserted on the closest location on the river branch they belong to. Additionally, their chainages will be automatically computed based on this location.
The Import from MIKE 11 option enable import of River model data from DHI’s River modelling package; MIKE 11 in to the River module of MIKE HYDRO.
More details on the MIKE 11 Import can be found in MIKE HYDRO River documentation.
Import from ISIS option concern River modelling and conversion of River model data in to the River module of MIKE HYDRO.
More details on the MIKE 11 Import can be found in MIKE HYDRO River documentation.
