The scientific community, councillors and local bodies are all sources of invaluable information (University of Caen Basse-Normandy, town halls, Dieppe conglomeration).
- The Saâne Valley is confronted by two natural phenomena, one linked to terrestrial phenomena – flooding, and the other linked to meteorological-maritime phenomena – erosion and receding cliffs. The lower valley was flooded in 1995, 1999 and 2000 with consequences for the natural area and human activities. The cliff-lined coast, emblematic of this sector, has a tendency to recede and to erode. Despite this sometimes important progressive tendency in certain sectors (Cap d’Ailly), urbanisation and human activities have progressively expanded from the depth of the valley to the hillsides, sometimes even to the cliff tops.Urbanisation first developed on the west bank of the lower valley, sheltered from the prevailing winds. The first developments in the valley were the sea walls built to protect from British attacks. It was not until the 18th Century, with its fashion for sea bathing, that access to the beaches increased, huts were built high on the beaches and urbanisation on the sea front of Quiberville-sur-Mer occurred. The buse groyne and the road along the sea front linking Quiberville to Sainte-Marguerite were also built in the 18th Century. Sainte-Marguerite was developed later, after the war.
