  1. 1. Biodiversity and habitat conditions in reaches with high flow velocity along gradients in hydrological and geomorphological alteration : A study of six rivers in Sweden

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

    Author : Anders Aalto; [2021]
    Keywords : Hydrology; Geomorphology; Biological variables; Human alteration;

    Abstract : The vast majority of rivers in the developed world are affected by human alteration, which in turn negatively affects the species that rely on these highly diverse and species rich areas to survive. Homogenization of previously heterogenic areas due to a change in water discharge and the substrate availability in the rivers is often regarded as the main reason for the loss of species richness in rivers and the riparian zone.

  2. 2. Machine Learning Applied to Reach Classification in a Northern Sweden Catchment

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

    Author : Mariana dos Santos Toledo Busarello; [2021]
    Keywords : machine learning; geomorphology; random forest; channel type;

    Abstract : An accurate fine resolution classification of river systems positively impacts the process of assessment and monitoring of water courses, as stressed by the European Commission’s Water Framework Directive. Being able to attribute classes using remotely obtained data can be advantageous to perform extensive classification of reaches without the use of field work, with some methods also allowing to identify which features best described each of the process domains.

  3. 3. A two-stage ditch – a source or sinks of nutrients and sediment : evaluation of sediment loss and inundation frequency

    University essay from SLU/Dept. of Soil and Environment

    Author : Sheryl Ilao Åström; [2021]
    Keywords : Two-stage ditch; geomorphology; inundation frequency; channel evolution; water quality; agricultural ditch;

    Abstract : Human-made channel systems in the agricultural landscape have received critical attention due to the dire consequences on water quality and increasing eutrophication polluting receiving aquatic systems. Trapezoidal-formed (traditional) ditches have been scrutinized and a new mitigation measure for channelized drainage systems has gained a great deal of attention i. READ MORE

  4. 4. The Site of an Unidentified Greek Settlement? New Surveys in Coda Volpe on Eastern Sicily

    Keywords : Archaeology; Archaic Age; Catania; Coda Volpe; Greek Colonization; Micro-archaeology; Periphery; Post-Colonial Theory; Sicily; Survey; Symaetus;

    Abstract : This study examines Greek colonisation’s potential for archaeology in relation to Coda Volpe district on eastern Sicily where necropoleis indicate the existence of unidentified both Greek and Roman settlements. Recent initial surveys near the Simeto delta suggests the location of a periphery, without any previous systematic study, prospecting or geophysical survey. READ MORE
