  1. 1. Modelling the Water Table in a Bog

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Bowley; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. Effects of Forest Ditch Cleaning on Surface Water Quality

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

    Author : Emeli Arvidsson; [2023]
    Keywords : Ditch cleaning; forest clear-cut; water quality; water chemistry;

    Abstract : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. READ MORE

  4. 3. Hydrogeological and economic analysis of a groundwater-based water supply system in rural Nepal

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Author : Hamon Hedayatnasab; [2023]
    Keywords : Technology and Engineering;

    Abstract : Access to safe drinking water and sanitation is a given standard and considered as basic human rights in urban areas and industrialized countries. However, 40 % of the world's population living in rural areas in developing countries lack access to safe drinking water. READ MORE

  5. 4. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  6. 5. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Lindgren; [2021-03-10]
    Keywords : acid sulphate soils; metal distribution; surface water; climate; physicochemistry;

    Abstract : Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presence of acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and the soils are today threatening many of the national environmental goals of Sweden. READ MORE
