    Author : Sandra Domingos Sambo; [2021]
    Keywords : rdought; Standardized Precipitation Evapotranspiration Index; Limpopo River basin; Normalized difference vegetation index; Mann-Kendall Test; Correlation analysis; Earth and Environmental Sciences;

    Abstract : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. READ MORE

  3. 22. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Abigail Huertas Herrera; [2021]
    Keywords : Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Abstract : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  4. 23. Investigation of Thermal Maturity of  Organic Matter at the Cambro Ordovician Transition in the Zagros Basin, Iran

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Niall Gibbons; [2021]
    Keywords : acritarchs; thermal maturity; Zagros Basin; hydrocarbons; source rocks; paleoenvironment;

    Abstract : The thermal maturity of sediments from the upper Cambrian to lower Ordovician Mila and Ilbeyk  formations in the Zagros Basin in southwestern Iran is evaluated in this thesis. A number of low-cost,  fast, optical evaluation methods are utilised to assess their effectiveness for providing accurate, well  constrained thermal maturity results. READ MORE

  5. 24. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Annejet Tuinstra; [2021]
    Keywords : wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Abstract : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. READ MORE

  6. 25. Patterns and factors affecting brownification in a boreal river

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emil Winqvist; [2021]
    Keywords : Bolmen; brownification; precipitation; discharge; sulfur deposition; land use; trend analysis; Technology and Engineering;

    Abstract : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. READ MORE
