2. 1. Cycle paths’ degradation processes and surface condition assessment

   Author : Martin Larsson; Sigurdur Erlingsson; Anna Niska; Inge Hoff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction design; cycle paths; degradation; distress modes; maintenance; municipalities; survey; cycling comfort; road surface measurements; surface evenness; surface texture; Building Materials; Byggnadsmaterial;

   Abstract : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. READ MORE

4. 2. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet

   Author : Charalampos Charalampidis; Veijo Pohjola; Dirk van As; Rickard Pettersson; Douglas Benn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland ice sheet; accumulation area; automatic weather stations; surface energy balance; melt–albedo feedback; surface mass budget; snow; firn; meltwater; percolation; refreezing; runoff;

   Abstract : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. READ MORE

5. 3. Global-Scale Modelling of the Land-Surface Water Balance : Development and Analysis of WASMOD-M

   Author : Elin Widén-Nilsson; Sven Halldin; Chong-yu Xu; Lars-Christer Lundin; Jens Christian Refsgaard; Uppsala universitet; []
   Keywords : Hydrology; Global; Water balance; Runoff; Regionalisation; Model uncertainty; Multi-objective; Parameter; Evaluation criteria; Routing; Climate change; Hydrologi;

   Abstract : Water is essential for all life on earth. Global population increase and climate change are projected to increase the water stress, which already today is very high in many areas of the world. The differences between the largest and smallest global runoff estimates exceed the highest continental runoff estimates. READ MORE

6. 4. Atmospheric corrosion and runoff processes on copper and zinc as roofing materials

   Author : Wenle He; KTH; []
   Keywords : atmospheric corrosion; corrosion rate; runoff rate; copper; zinc; field study; laboratory study; roof; first flush; rain quantity; rain intensity; rain pH; dry and wet deposition; corrosion and runoff process;

   Abstract : An extensive investigation with parallel field andlaboratory exposures has been conducted to elucidateatmospheric corrosion and metal runoff processes on copper andzinc used for roofing applications. Detailed studies have beenperformed to disclose the effect of various parameters on therunoff rate including: surface inclination and orientation,natural patination (age), patina composition, rain duration andvolume, rain pH, and length of dry periods inbetween rainevents.

7. 5. Influence of Sea Surface Temperature on Rainfall and Runof in Northeastern South America: Analysis and Modeling

   Author : Cintia Bertacchi Uvo; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kartografi; marklära; geomorfologi; Fysisk geografi; climatology; pedology; cartography; Physical geography; geomorphology; sea surface temperature; rainfall-runoff; Amazonia; precipitation; Northeast Brazil; klimatologi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi;

   Abstract : This work represents an amalgam of a group of studies with the purpose of understanding the influence of the Pacific and Atlantic sea surface temperature on precipitation and river discharge in Northeastern South America. Sea surface temperature is a good representative of phenomena such as ENSO that, in turn, cause worldwide climate variability. READ MORE
