Note card Surface drain Carinthia

The “indicative maps surface runoff” represent the maximum runoff ratios for an assumed rain with 60 mm precipitation within 30 minutes. The topography is based on laser scan data (flight years between 2006-2015), which for a cell size
2 by 2 meters were gridded. Buildings were automatically removed from it. Bridges,
Passages, canals, garden and pedestal walls etc. are not taken into account.
Note cards include 4 sub-cards: Hazard Categories, Maximum Specific Drain (l/sm), Maximum Speed (m/s), Maximum Water Depth (m)
