Version 2017.5.0

Version 2017.5.0 is released on preview.tygron.com on Friday August 11th 2017

Rainfall overlay:

• Multiple result types can now be calculated at once and visualized in the overlays bar at the right as a group, where you have a parent result type and child result types. This is also applicable to the Subsidence overlay(s).
• Implementation of the discharge calculation (stuwformule), which ensures a more refined calculation of the water flow between water level areas. Attributes: WEIR_WIDTH, WEIR_COEFFICIENT (default 1.1, different types of weirs have different flow coefficients), WEIR_N (the default value 3/2 is for a horizontal weir, change accordingly for your type of weir)
• Implementation of two new hydrological constructions (pump and culvert) next to the already existing weirs and sewer overflows to define different relations between (water level) areas
• The new result type ‘ Building impact’, which shows all the constructions which will be flooded (defined by the IMPACT_FLOOD_THRESHOLD_M attribute) with the set rain event type. The result type is also a visualization of the new attribute ‘CRITICAL_INFRASCTRUCTURE’ in the function values table, in where a categorization in critical buildings is made. The values that can be entered in the function values table are: not critical = 0 (for example sheds or a park), important = 1 (most buildings), critical = 2 (such as a hospital or a school).
• The rain event type can either be set to an equal distribution of rain, or an adjustable distribution of rain over time for modeling for example when it is raining harder at the start of a rain fall
• More insight in when the Engine is calculating a result
• The speed for water flowing over the sewer overflow buildings to surface area water is adjustable (attribute: SPEED in m3/sec)

TQL:

• The GRIDTYPE clause is deprecated. Use instead the GRID clause, in combination with the ID of the overlay (old queries using the gridtype clause will still work)

License system:

• The user knows his/her license type from the main menu in the upper right hand corner. By clicking on the icon, a short overview is given
• Up to 10 project versions can now be saved, deleted and name changes can be made
• Saved projects will be stored for one year

Performance:

• Faster calculation of the grid overlays by changes to the GPU architecture.
• Better caching of Geotiffs for ground water levels for faster refreshing of an overlay
