The flood of the polder Land van Maas en Waal in 1805 was simulated (Ph.D. study by A.W. Hesselink) using the FLS-model of Delft Hydraulics (WL). The model was calibrated using historical data of the flood. The four pictures below show the situation:
(Above) Just after the dike breach on February 13, 1805, 6:00 AM.
(Above) At 5:00 PM that same day, most of the eastern part of the polder was flooded, with the exception of the Late Pleistocene eolian dunes, that reach up to 20 m above sealevel (most of the polder is at 10 m above sealevel or lower).
(Above) Shows the situation on February 14, at 9:00 AM.
(Above) Shows the situation on February 17 at 12:00 AM.
The floodwaters first followed the ditches and canals. The curve at the bottom in each picture shows the water level fluctuation over time.
