We have changed some important things around Core+ DynamicFlood in Sweden:

• Rain events now differ based on the region they are in. 
• We have updated the surface roughness parameters to match MSB recommendations.
• We updated the default maximum infiltration rate in sewered areas from 36 mm/hr to 21 mm/hr to align with sewer dimensioning practice in Sweden.

These changes only affect new workspaces, so you must create a new workspace for these changes to take effect. Your old workspaces remain unchanged.

For more information, please read the accompanying blog post (in Swedish) or check the Core+ DynamicFlood changelog.

Scalgo Live on saanut merkittävän päivityksen: rankkasadeanalyysit huomioivat nyt koneoppimisen avulla tuotetun maanpeitemallin ja pintamaalajien vaikutuksen veden imeytymiseen. Lisäksi kaupunkialueilla analyysit tarjoavat arvion hulevesiviemärien vaikutuksesta.

Tule mukaan webinaariin!

4. lokakuuta 2024 klo 10.00-11.00 Pietu Pankkonen, Suomen markkinapäällikkö, esittelee, miten veden imeytymisen huomioivat analyysit on tuotettu ja miten voit hyödyntää niitä työssäsi.

Lyhyt introvideo

Blogikirjoitus veden imeytymisestä: Uusi päivitys SCALGO Liveen - Veden imeytyminen nyt osana rankkasadeanalyysejä.

Today we have truly opened up a world of Scalgo Live. You can now access full Scalgo Live setups for all 12 countries where these are currently available, covering more than 10 million square kilometres. For all other regions, you will be able to upload your own data, making it easy to work in Scalgo Live anywhere in the world! 

We are not stopping here, we are always working on adding more countries to Scalgo Live. These will also be available to all users as they are released.

For more information about this big step for Scalgo Live, please see the accompanying blog post.

In Core+ DynamicFlood, the default rain events used in Norway are now local design rains based on rainfall statistics from the region the workspace is in, with climate factors available based on the recommendations from the authorities. For more information, read the accompanying blog post.

Furthermore, Core+ DynamicFlood users in all countries can now see the timestep of running simulations in real time and obtain an estimate of the model's completion time. Please read the blog post for more information about this new feature.

Interested in how a particular sea-level rise affects the buildings in a region? You can now download building flood risk information for the sea-level analysis, similar to what has long been possible for the Flash Flood Map. This is available from the sea-level analysis - you simply need to select the "buildings" tap in the download window.  The result is a set of building polygons in the affected area with additional fields providing the following information:

• The minimum sea-level at which any part of the building interior is in contact with the sea.
• The length of the wetted perimeter at the selected sea-level. The wettede perimeter is the part of the buildings perimeter in contact with the sea.
• The wetted area, found by combining the wetted perimeter with the depth of the water adjacent to the building to get the area of the building perimeter in contact with the sea.
• The maximum water depth along the building perimeter, as well as the coordinates where this depth can be found.

Alongside the annotated building polygons you also get a layer of lines denoting the wetted perimeter of each building, these perimeters are annotated with the same flood-related information as the building polygons. It makes it easy to highlight the part of the buildings that are at risk of flooding.

In Workspaces, you can now get contour maps for terrains you design, and buildings can be removed and modified as editable Objects, see more information in the accompanying blog post.

Contour lines are now generated as part of all Workspace computations. When you create your terrain design, the contours are updated to describe the new terrain accordingly. The contours are available in many different contour intervals, controlled via the contour interval slider that also exists for the national contour maps.

Furthermore, we have improved the way buildings are included in Workspaces. Previously, buildings were implicitly included by raising their elevation in the terrain model, making them unmodifiable terrain edits. Now, they are regular edits that can easily be removed or modified. This has been done by introducing a new group of editing tools called Objects. The existing subsurface tools are considered objects, and are now available in this group.

Please read the blog post for more information about this release.

We have just released some exciting features for Modelspaces in SCALGO Live.  You can now query information about water flow, volume, and depth from your dynamic flood simulations.

We have also created a whole new set of visualisation styles to animate the dynamics of velocity.  The old styles are still available, should you need them.

Please read more in the accompanying blog post.

Today we announce the availability of a nationwide high-resolution land cover map for SCALGO Live in Germany. The map, produced by SCALGO, is based on machine learning techniques and has a high resolution of 20 cm.

It is available as a standalone layer in the Land cover category in the library. 

The map is fully integrated into SCALGO Live Germany and is, for instance, used to show aggregate land cover information for watershed queries. For more information please see the complete release announcement.

German cadastral maps

As part of this release we are also adding aggregated cadastral data to SCALGO Live Germany. The new layer, called Flurstücke, is available in the ALKIS category. We have also computed aggregated land cover information for each land parcel, you will find this layer in the Land Cover category.

Note that only a select number of federal states are available in the Flurstücke layer, please consult the documentation for more information about this.

SCALGO Live has long supported creating basins and protrusions having side slopes with a given gradient.   The way this works is that you draw a polygon covering the bottom of your basin or the top of your protrusion (hill).  Then you specify a gradient, and SCALGO Live automatically interpolates between the drawn flat area and the surrounding terrain while respecting the specified gradient.

There are use cases, however, where it is more natural to be able to specify the outer boundary of your basin or hill.   For example, you may have a given plot of land where you want to create water storage.

SCALGO Live now supports this use case:    Again you draw a polygon and specify a gradient, but this time SCALGO Live adds the slope on the inside.

The tools you have always used for creating basins and protrusions now support both ways of specifying side slopes.  Use the checkbox "Side slopes are outside" if you want to add slopes on the outside of your area (the default is now to add them on the inside).

The two modes behave a bit differently:

• When adding outside slopes, the polygon you draw is a flat horizontal polygon (since it's the bottom of your basin), so in the profile view you will see all vertices at the same elevation (and you cannot change this).   How far the side slopes will go depends on the elevation of the terrain, for an uneven terrain it is not easily predictable.

• When adding inside slopes, the polygon you draw actually has 3D coordinates (SCALGO Live automatically samples the terrain at each vertex).   This makes it possible to create a basin whose outside aligns with the terrain along the given area boundary.   From these 3D coordinates, SCALGO Live then computes the appropriate sloping to achieve the target depth (or height for protrusions).    The depth is always measured from the lowest boundary vertex, the height is measured from the highest boundary vertex.
  
  When you edit the boundary of such a basin, you may have to readjust the elevations at the vertices to make sure it again aligns with the terrain, otherwise you'll have sharp edges on the boundary.

Since the very beginnings of SCALGO Live, it was possible to modify the terrain model to see how this influences the flow of water and the various analyses.

The first tools were quite simple, and allowed you to draw walls, depressions, or protrusions with vertical walls only. Then came side slopes for more realistic dams and basins, the possibility to specify the cross section (for instance to represent a river bed according to actual measurements), and most recently the ability to create a terrain by drawing contour lines.

Until now, when you draw a path feature using the "interpolate", "raise", or "raise flat" tools without any side slopes, it was still represented in the terrain as we implemented it in the first version many years ago (top figure below).

We have now changed it so that when you create a simple path without side slopes or general cross sections, it is added to the terrain using the same method that we use for general paths (that is, for paths with side slopes or cross sections). As you can see in the bottom figure, this avoids the traditional plateaus at each vertex, and in general fits better with the other ways of using our tools.

It is worth noting that the new method is applied only to newly created features - your existing features remain unchanged. If you want an existing path feature to use the new method, use "Edit both cross sections" from the context menu, select "Width only", and save again. Note that you will not be able to go back to the traditional way, though.
