1. 1. The influence of temporal rainfall distribution and storm movement on flood depth in urban pluvial cloud burst modeling

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Michael Henrich; [2019]
   Keywords : Pluvial flooding; cloud burst; flood modeling; MIKE 21; temporal distribution; storm movement; areal reduction factors; ARFs; hyetograph; design storm; CDS; Pluviala översvämningar; skyfall; översvämningsmodellering; MIKE 21; regnmönstrets tidsfördelning; molnrörelse; areal reduktion av nederbörd; ARFs; hyetograph; typregn; CDS;

   Abstract : Pluvial floods are the most difficult and to date least investigated phenomena in urban hydrology. While efforts are being made to increase the knowledge base concerning this type of flooding, a large part of the difficulty lies in the nature of the precipitation. READ MORE

3. 2. Ephemeral Streams in Boreal Landscapes : A Surface Water Statistical Analysis of Ephemeral Streams Chemical Components

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Oscar Davies; [2019]
   Keywords : Ephemeral streams; boreal landscapes; Krycklan; DOC; Efemär; Boreal landskap; Krycklan; DOC;

   Abstract : Boreal landscapes cover a large part of both Sweden and the northern hemisphere. The hydrology of the boreal landscape is complex, with several factors that can affect it in a physical and/or chemical manner. READ MORE

4. 3. Hydrologic modelling of the Zackenberg river basin : an applied study using the Soil and Water Assessment Tool

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Malin Ahlbäck; [2018]
   Keywords : Greenland; SWAT; High Arctic; Distributed Hydrologic Modelling; GIS; surface Water; Earth and Environmental Sciences;

   Abstract : Since the 1980s, the Arctic has experienced an amplified warming of more than twice the rate of the global-mean, leading to large-scale changes in the Arctic hydrologic system, ultimately having cascading feedbacks on the global climate. However, few of today’s distributed models manage to capture the complex processes in Arctic hydrology, and therefore, the aim of this thesis was to evaluate the usage of the distributed Soil and Water Assessment Tool (SWAT) model, to see whether it could capture the different surface water paths and processes characterizing the Arctic water cycle.

5. 4. Statistical Modelling of Permafrost Extent in the Circum-Arctic Region

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Patricia Koch; [2018]
   Keywords : permafrost; soil organic carbon; growing degree days; statistical modelling; Earth and Environmental Sciences;

   Abstract : Permafrost regions cover approximately a quarter of the Northern Hemisphere and thawing has been recorded in many different locations. The thawing process is likely to continue given that the Northern Latitudes will experience increased warming, which is known as the Arctic Amplification Factor. READ MORE

6. 5. Catchment influences on mercury methylation in a peatland chronosequence

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Robin Hagblom; [2017]
   Keywords : methyl mercury; GIS; northern peatland; mire; watershed; elevation;

   Abstract : Since the beginning of industrialization, emissions of mercury (Hg) from human activities in excess of natural levels have increased depo-sition rates to ecosystems, storage in soils and loading to aquatic envi-ronments. Toxicity to animals, subject to this accumulation, as well as to humans consuming them, are the major concerns driving research on this subject. READ MORE
