(author)Man-made islands in the Mackenzie river (Canada) for oil exploitation may obstruct the free flow of ice during spring break up. These ice dams may cause considerable rise of the water level in the rivers, resulting in floods. A numerical model is presented to simulate ice dam formation an river floods.conference paper 1983

(author)When longshore sediment transport is interrupted by a construction along a coast, e.g harbour moles or a dredged approach channel, the equilibrium of the coastline may be disturbed. When the disruption is caused by breakwaters, the longshore transport that is held back will cause accretion updrift of the breakwaters and erosion downdrift of them...conference paper 1981

Verhagen, H.J. (author), Loman, G.J.A. (author)Norman Hells is situated on the north bank of the Mackenzie River, 145 km south of the Arctic Circle. The use of a pool-wide water flood system for secondary recovery and the features of the oil-bearing structure require six man-made platforms to provide vertical access to the portion of the oil pool that 1 ies beneath the Mackenzie River (60%)....report 1980
