Which dykes are you referring to? The sea dykes won't matter as the area in question is not below sea level. The river waal is 8 meters above sea level at nijmegen for example. The area is subject to river flooding, but not much in september as the rivers are down. Blowing up the dykes would basically screw fortress holland, but all that would do is secure the western flank of the allied advance, as the garrison of holland would be under 20 ft of water. Spring would suck, but the allies would not be impeded much in the fall.
Actually mild flooding off the courses of the Maas and Rhine would help them as that would secure their eastern flank as well.
The dikes along the Mass farther south that would still be held by the germans which would cause a domino effect down the line and cause the others in allied controlled territory to fail and for the river to crest and flood the country side (especially the territory between the Maas and the Rhine which is extremely narrow where the allied spearheads where)
Model wouldn't want to attack them from the south(in Holland itself), he would use his reserves on the east bank of the rhine to attack the spearheads inside Germany who would be struggling with difficult supply lines and probably numerical inferiority
