  1. 1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  3. 2. Evaluation of River Restoration Measures: Interstitial Habitat Variables and Salmon Hatching Rates as Indicators of Success

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Limnologi

    Författare :Jonas Emanuelsson; [2023]
    Nyckelord :;

    Sammanfattning : River ecosystems are some of the most complex ecosystems on Earth, characterized by a highly heterogenous environment which is able to sustain a disproportionally high level of biodiversity in relation to the area of which they occupy. However, anthropogenic activities are encroaching on the highly diverse riverine landscape, threatening freshwater biodiversity. LÄS MER

  4. 3. Evaluation of rainfall-runoff modelling data in Sebeya Catchment, Rwanda - Recommendations for improved flood hazard analysis

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Anna Ebbersten; [2023]
    Nyckelord :Rwanda; Sebeya; hydrological modelling; rainfall-runoff; catchment; HEC-HMS; Technology and Engineering;

    Sammanfattning : Rwanda has experienced an increase in the frequency of riverine floods since the mid 2000s, and the future impact of climate change on the hydrological cycle is uncertain. Flood hazard analysis is one tool used to reduce flood risks; the analysis is often based on models which requires hydrological and meteorological data. LÄS MER

  5. 4. Evaluating the feasibility of implementing ecological flows at Fridafors Hydropower plant

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Michelle Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : Sweden’s almost 2200 hydropower plants and their attached dams are going to be re-licensed with regards to the new environmental legislations made by the government and EU’s water framework directive. As a solution to restore and improve the health of the Swedish riverine systems, a number of different mitigation measures are suggested. LÄS MER

  7. 5. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

    Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Andreas Vernby; [2021]
    Nyckelord :Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

    Sammanfattning : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. LÄS MER
