1. 1. Geomorphic and particle attributes influence on entrainment and sediment transport in semi-alluvial streams

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Joe Sundin; [2020]
   Keywords : Stream geomorphology; Sediment transport; Entrainment; Grain attributes; Bankfull shear stress; Dimensionless critical shear stress; Slope; Boulders; Constrainment;

   Abstract : Streams around the world are shaped by physical processes between water and sediment transport which generates unique geomorphic structures for each stream. This study aimed to evaluated how geomorphic structures and grain attributes would influence entrainment frequency and transport distance of traced clasts. READ MORE

3. 2. 2D Effects of Geomorphology and Discharge on Hyporheic Exchange—a HEC-RAS Modelling Study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Olivia Preston; [2020]
   Keywords : average hyporheic exchange velocity; water surface elevation; water surface concavity; hydrostatic head;

   Abstract : Hyporheic exchange is an ecologically and biogeochemically essential function of rivers and streams. One important driver of hydrostatic (hyporheic) exchange is gra- dients in the hydrostatic hydraulic head at the streambed. READ MORE

4. 3. Where does the stream begin? Stream initiation under variable wetness conditions in a boreal landscape

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Evelina Gallon; Sanna Lindberg; [2014]
   Keywords : ;

   Abstract : The understanding of where the streams begin is an important factor in both hydrology and geomorphology, as well as for land use activities. Despite this, only a few research projects have been done in a snowmelt-dominated boreal landscape. READ MORE

5. 4. Late Weichselian glacial and geomorphological reconstruction of South-Western Scania, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Kilian Barth; [2011]
   Keywords : Trelleborg; Vellinge; ice stream; Scania; ice lobe; late Weichselian; Malmö; Skåne; Weichsel; Söderslätt; Backlandskapet; isström ; Earth and Environmental Sciences;

   Abstract : This study was carried out to deliver new insight into the late Weichselian landscape development of South Western Scania and to make regional scale glaciation models of South-Western Scandinavia more accurate. The goal of this study is to find out how the latest ice advances affected the study area. READ MORE
