View source for Falen keringen template

Het falen van keringen is een van de toepassingen van het {{software}}. Hiervoor is een template project genaamd Falen keringen template gemaakt. Om dit template effectief in te kunnen zetten is deze handleiding gemaakt. Daarin wordt de te volgen werkwijze beschreven en worden aandachtspunten beschreven.

==Required data==
* AHN100x100.geojson
* Peilgebieden.geojson
* Duikers_WVS_041219.geojson
* Peilen hoofdsysteem Noord 121219.geojson

Experience with using the {{software}}, using the [[Water_Overlay_Wizard|Water overlay wizard]] and [[Geo_data_wizard|Geo data wizard]] is required.

==Steps==
Below the steps for using the template project on a new project area and to calculate and export the results for further analysis. 

===Apply template on new project area===
In this step we will apply the template Falen keringen V1 project on a new project area. 
{{Editor steps|title=
|Log in to the {{software}}; the [[Roadmap#engine.tygron.com_.28Long_Term_Support.29|LTS]]
|Read the [[Main_Menu#Headlines_panel|headlines]] to know if there are any failures, for example at the data provider level which could have effect on creating new projects without certain datasets.
|Click on ''New Project'' 
|Give the new project a name and click on ''Use Falen keringen V1 template''
|Zoom in the next step to the area where you want to create a 3D model from. If required, adjust the size of the square/ rectangle with the sliders to adjust the size of the to be created project. The part of the map in the square/rectangle will become the 3D model.
|Click on the Advanced settings and uncheck IMWA. If AHN3 data is available as open data for this project area, check the Use latest AHN3 option.    
|Click on the ''Generate map'' button.
|The new project will now be created from the various [[Project_Sources|open data sources]].

===Import water level areas===
The water level areas contain water levels for various scenario's and will be used to determine the water level of the water body which will flow into the breach.
{{Editor steps|title=
|Open the [[Geo_data_wizard|Geo data wizard]]
|Click on next and choose for [[Areas]]
|In the next step choose to ''Import a GeoJSON file'' and select the file '''Peilen hoofdsysteem Noord 121219.geojson'''
|In step 2, set the slider on 20m to create polygons from the point data. 
|Choose the attribute .... for the name of the water level areas in step 5.
|Finish the wizard
|In the Current tab, click on the button Overlays
|Select the overlay ''Peilen hoofdsysteem'' from the left panel and and click on Add areas with attribute in the bottom right corner.
|In the panel that pops up, choose the attribute .... and click on Add.

===Define breach location===
{{Editor steps|title=
|[[How to add and remove an Area|Add a new Area]] to the project. This will be the breach area. Give it a recognizable name. 
|Draw the breach area in the [[3D world]], in the location where the water from the breach should emerge (see tips below in gallery). 
|[[How to add and remove an Attribute|Add an Attribute]] to the created [[Area]], with the name ''BRESHOOGTE'' and the [[Breach height (Water Overlay)|breach height]] value. Click on the location of the breach to know the terrain height. 
}}
<gallery mode=nolines>
File:Breach.JPG|Draw the breach area not too close to the water body and only on the slope of the levee on the side of the area that is going to flood.

===Configure flooding overlay===
====Breach====
{{Editor steps|title=
|Click in the [[Current_Situation|Current situation]] on the button Overlays and select the Overstroming T=200 overlay
|In the right panel, click on Configuration wizard to start the wizard
|In step 1, specify the time for the simulation calculation period.
|In step 2.1 select your breach area from the dropdown menu and fill in:
|Fixed height and width. Leave [[Breach_angle_(Water_Overlay)|breach angle]] empty. Use for the [[Breach_speed_(Water_Overlay)|breach critical speed]] .... 
|Select use external area.
|Use an [[External_surface_level_(Water_Overlay)|external surface level]] which is lower than the [[Breach_height_(Water_Overlay)|breach height]]
|Use for the [[External_water_level_(Water_Overlay)|external water level]] the measured water levels from the Peilen hoofdsysteem overlay.
|Calculate for the [[External_area_(Water_Overlay)|external area]] 10 x the flow rate that flows through the breach ''te checken via show water balance''. Magnitude: 10.000.000 m2. If the expected water level fall of the main system is known, take this into account for the external area size.

====Culverts====
{{Editor steps|title=
|Choose from step 2.3 to 2.6.1 the option ''Do nothing'' and proceed with next.
|In the step 2.6.4 Culverts, aelect ''Import culverts'' and click on Import culverts. 
|In the [[Geo_data_wizard|Geo data wizard]] select the file '''Duikers_WVS_041219.geojson''' 
}}

====Finish wizard====
{{Editor steps|title=
|Choose from step 2.6.3 to 2.6.5 the option ''Do nothing''
|In step 3 and 4 proceed with next.
|In step 5 make sure the [[Surface_elevation_result_type_(Water_Overlay)|Surface elevation]], [[Surface_max_speed_result_type_(Water_Overlay)|Surface max speed]], [[Surface_max_value_result_type_(Water_Overlay)|Surface max value]] and [[Base_types_result_type_(Water_Overlay)|Base types]] are checked. 
|Choose an amount of [[Timeframes_(Water_Overlay)|timeframes]] by taking into account the calculation time (which is entered in step 1), so that for example, you arrive at timesteps per hour or day.

===Export results===
In this last step, the results will be exported as raster data. 
{{Editor steps|title=
|Make sure the overlay is recalculated. Otherwise, select the Overstromingen T=200 overlay and click in the right panel on Update now.
|When the overlay is calculated, play the overlay to see the results and check for yourself if they are realistic. If not, open the configuration wizard and adjust settings. Make sure you recalcuate the overlay again by clicking on Update now.
|Click on Export Grid File and check if the name is correct, choose for [[GeoTiff|GeoTIFF]] as format and check the All frames box. The [[Surface_max_value_result_type_(Water_Overlay)|Surface max value]] overlay is now exported. 
|Click on export and create a new folder to save all the files
|Select the Maximale snelheid t=200 overlay and repeat step 2 and 3 for exporting the [[Surface_max_speed_result_type_(Water_Overlay)|Surface max speed]] overlay. Don't check the All frames box but select the last timeframe instead.
| 
}}
<gallery mode=nolines>
File:Export_max_value.JPG|For the Surface max value overlay click on Export Grid File and check the All frames box to export all the timeframes 
File:Export_max_speed.JPG|For the Surface max speed overlay click on Export Grid File and select the last timeframe from the dropdown to only export the last timeframe
</gallery>

The final [[GeoTiff|GeoTIFFs]] need to be opened in a GIS program and saved as a ''map with proper legend and title in jpg format''.
These maps needs to be created from the exported data:
* Maximale stroomsnelheid: [[Surface_max_speed_result_type_(Water_Overlay)|Surface max speed]] map at the last timeframe
* Maximale waterdiepte per locatie: [[Surface_max_value_result_type_(Water_Overlay)|Surface max value]] map at the last timeframe
* Waterdiepte in de tijd/tijd-tot-inundatie: multiple [[Surface_max_value_result_type_(Water_Overlay)|Surface max value]] maps at different timeframes. Create for example a map for every one or two hours (depending on the simulation time).
