| |
| | |
| ==Three distinct implementations of Dikes==
| |
| | |
| ===River Flood Protection===
| |
| : Along some of the larger rivers in the world (Rhine, Mississippi) elaborate dike structures have been constructed to prevent the river and its delta from flooding the banks.
| |
| | |
| ===Coastal Flood Protection===
| |
| : Many coastal flatlands are protected by complex flood defenses, for example the sea wall at Vancouver BC (Canada). An extreme example is the Netherlands, where huge dike structures such as the Delta works protect against coastal inundations. Besides protecting the landmass, these huge dikes are also used in the Netherlands to claim more land that was originally below mean sea level.
| |
| | |
| ===Spur dykes or groynes===
| |
| : These man made constructions are implemented as erosion prevention. These dikes are usually constructed at an angle to the bank or coast, and can be found in inland rivers and canals, and at the sea coast. They are for instance deployed in the 'Room for the Rivers' project in the Netherlands to counter bank erosion.

| =How do Dikes relate to the {{software}}?=
| |
| Water management is an important factor of spatial planning. Dikes (or levees) are some of the most basic water management measures that can be implemented; just build a wall and keep the water out!
| |
| | |
| In the {{software}} these dikes play a special part. As dedicated [[constructions]] they can affect [[Areas#Safe zone|safe zones and floods]]. By constructing a dike as an independent [[Actions|action]] or as part of a [[Predefined Measures|measure]], the safe zone terrain will be expanded, protecting more houses and industry when a flood occurs. This can all be visualized in the {{software}} and a dedicated [[Indicators|indicator]] can be set up to have the implementation of dikes score on the [[stakeholder]] progression.

|
| Implementation as action allows for trying out new plans and ideas. This can for instance be convenient when the project is part of an outreach to non-planners, for example residents or business owners, to let them try their own plans and ideas without an engineer pre-planning the flood protection for them. This can give session participants a stronger sentiment of involvement with the project. | | Implementation as action allows for trying out new plans and ideas.

| ===Editing properties of a Dike as Action===
| |
| [[File:DikeActionRightPanel-Q3-2015.jpg|left|frame|Right Panel]]
| |
| The following properties can be edited of a new or already existing dike that is set up as an action:
| |
| ====Name====
| |
| [[File:DikeActionNameField-Q3-2015.jpg|right|thumb|Enter new name]]
| |
| : In the name field on the right panel, the default name can be replaced by entering a more suitable name. This can be for instance a reference to the top and side functions (see below).
| |
| <br clear=right>
| |
| | |
| ====Image====
| |
| [[File:DikeActionImageField-Q3-2015.jpg|right|thumb|Select image to change it]]
| |
| : By selecting the Image field, a new window will open. Here the user can select a new image, or upload a custom asset to be used as image. When uploading a new asset, the image (a ''.png'' file) must adhere to the resolution of 200x100 pixels.
| |
| <br clear=right>
| |
| ====Description====
| |
| [[File:DikeActionDescriptionField-Q3-2015.jpg|thumb|right|Describe the dike here]]
| |
| : The description field on the right panel allows for a descriptive text to accompany the dike. The description is visible in the project main view when selecting the action belonging to the dike. This text can be a description of the top and side functions and/ or the impact thereof on the indicators. This is also a good space to elaborate on the dedicated name given earlier.
| |
| <br clear=right>
| |
| | |
| ====Top & side functions====
| |
| [[File:DikeActionFunctionFields-Q3-2015.jpg|thumb|right|Function fields]]
| |
| : This area is used for assigning specific [[functions]] to the top and side of the dike. This can make a dike affect indicators such as a [[Housing (Indicator)|building indicator]] or a [[Green (Indicator)|green indicator]]. When a dike has a bicycle lane as top function, constructing this dike will affect a building indicator if this indicator has such bicycle lanes as a target. Implementing trees as top function affects the green indicator, while implementing pavement as side function and an asphalt road as top function has a negative impact on the [[Heat (Indicator)|urban heat stress indicator]].
| |
| <br clear=right>
| |
| ====Fixed size====
| |
| [[File:DikeActionFixedSizeCheckBox-Q3-2015.jpg|thumb|right|Fixed size check box]]
| |
| : Check this box to ensure that a dike remains at a fixed size and does not adjust its size relatively to the terrain elevation present in the project area.
| |
| <br clear=right>
| |
| ====Height & width====
| |
| [[File:DikeActionDefaultSizeFields-Q3-2015.jpg|thumb|right|Enter here the default height and width]]
| |
| : These fields allow for adjustments of the height and width of the dike. These settings are the starting point during a session, however, the values can then still be adjusted when drawing in the dike placement.
| |
| <br clear=all>
| |
| | |
| ==Deployed as part of a (predefined) Measure==
| |
| | |
| : ''Note: it is currently only possible to assign functions to the top and side of a dike when deployed as an Action.''

| [[File:DikeMeasureRightPanel-Q3-2015.jpg|frame|left|Right Panel]] | | |howtos= |
| The following properties can be edited of a new or already existing Dike that can be deployed as part of a predefined measure:
| | * [[How to add a Levee Type to an Action Menu]] |
| ====Type====
| | * [[How to edit properties of a Levee Type]] |
| [[File:DikeMeasureTypeField-Q3-2015.jpg|frame|right|Select measure type DIKE from drop down menu]] | | * [[How to add a Levee Spatial to a Measure]] |
| : When creating a [[Measures#Spatials|Spatial Measure]], a dedicated type needs to be assigned. From the available options WATER, FLATTEN and DIKE in the drop down menu on the right panel, the last option (DIKE) needs to be selected for dikes deployed as measures.
| | * [[How to edit properties of a Levee Spatial]] |
| <br clear=right>
| | |seealso= |
| ====Relative and absolute height====
| | * [[LeveeSpatial]] |
| [[File:DikeMeasureHeightField-Q3-2015.jpg|frame|right|Enter relative and absolute height]] | | * [[Measure]] |
| : Dikes deployed as part of a measure will change height relative to an absolute height and the terrain elevation. When the terrain is 10 ft (or m) above sea level, and the absolute height of the dike is set to 17 ft (or m), the placed dike will have a relative height of 7 ft (or m). If further on in the project area the terrain height drops to 5 ft (or m), the dike relative height will increase to 12 ft (or m). In the height adjustment fields these values can be changed as desired. The value 'Current height at Inner Polygon' indicates the actual terrain elevation on the location of the mouse cursor in the 3D world. | | * [[Action Menu]] |

| ====Outer area====
| | {{Template:Editor_future_design_nav}} |
| [[File:DikeMeasureDrawouterAreaButton-Q3-2015.jpg|frame|right|Draw the Outer Area]] | | [[Category:Levee Type]][[Category:Items]] |
| : Drawing the Outer Area decides the surface area taken by the predefined measure. This Outer Area refers to the actual location, length and width of the dike. Selecting this option opens the brush panel on the bottom panel, under the project main view. By adjusting the brush, the desired size can be selected. The line brush would be the most suitable brush type for this construction.
| |
| <br clear=right>
| |
| ====Inner area====
| |
| [[File:DikeMeasureDrawInnerAreaButton-Q3-2015.jpg|frame|right|Draw the Inner Area]] | |
| : After drawing the Outer Area, an Inner Area is required to visualize the actual dike when the measure is implemented. This Inner Area decides, based on the set height of the dike, the slope of the sides of the dike. The wider the Inner Area is, the steeper the slopes will be, but also the wider the top layer will be. When the Inner and Outer Area width are equal, the slopes will be vertical. If the Inner Area is drawn offset of the center line, the side it is drawn on more will have steeper slopes. Selecting this option also opens the brush panel on the bottom panel, under the project main view. The available location will be visible as the only area in the 3D World that is not masked with a grey layer.
