LANDSCAPES OF WATER 23.04-02.05 Guest Instructors : Giambattista Zaccariotto Jan Stenersen


TROMSØ 69.6828° N, 18.9428° E


TOPOGRAPHY AND WATER BODIES


The urbanization on the Tromsø mainland originally stopped at the line of altitude at which water could be supplied by sole gravity.


WHAT ARE THE MAIN CHALLENGES FOR WATER (AND SNOW) MANAGEMENT ON TROMSテ郎A?

drainage blocked by frost and snow


snow removal, storage and cleaning from pollutants

sea level rise and increasing extreme weather events

POLLUTION POLLUTION LEVEL : LEVEL HIGH : HIGH

Streets, parking lots and additional pollutions coming from the airport and comercial areas characterize high level of pollution.

POLLUTION POLLUTION LEVEL : LEVEL LOW : LOW

Snow coming from the roads in residential areas, private housing with higher infiltration and absorption of pollutants to the soils during melting season.
