Version 2017.5.0

Version 2017.5.0 is planned for release 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 screen 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 buildings which will be flooded (defined by the IMPACT_FLOOD_THRESHOLD_M attribute) with the set rain event type. Also, constructions have a new attribute ‘CRITICAL_INFRASCTRUCTURE’ in the function values table, in where a categorization in critical buildings is made. Not critical = 0 (for example sheds or a park), Important = 1(for example buildings), critical buildings = 2 (such as a hospital or a school) is made.
• 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 changes to the names can be made

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
