Evolution of prodeltas : a print of glacier melting processes

Abstract : Coastal evolution in meters from 1966 to 2016 Prodeltas evolution in meters from 1966 to 2012 from side scan mosaics the Shoreline evolution measured by calculation between reference points Ice evolution than processes control coastal high-latitudes and how they will Coastal evolution in meters from 1966 to 2016 Question 1 : What are the effects of the glacier retreat on the hydrographic network ? First results show a decrease of the drainage density and the width of the active band which conducts to a clear concentration of the hydrographic ntework. Question 2 : What is the Kongsfjorden line evolution ? Coastal areas supplied by the hydrographic network become smaller Global progradation of the coast observed from 1966 to 2016 is focused on specific areas (linked to the prodeltas localisation Question 3 :What does happen to the sediments exported into the Kibgsfjorden ? A part of these sedimentray supply is stored into the prodeltas with an extension of 40 000 m
