  3. 2. Spatial and Temporal Variations in a Perennial Firn Aquifer on Lomonosovfonna, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Monika Hawrylak; Emma Nilsson; [2019]
    Keywords : perennial firn aquifer; ground penetrating radar; Svalbard; Lomonosovfonna; flerårig firnakvifer; georadar; Svalbard; Lomonosovfonna;

    Abstract : A firn aquifer is a type of englacial water storage that forms when surface meltwater fills up the pore space in porous firn. If the retention time exceeds one year the feature is regarded as perennial. The melt and accumulation rates as well as the available pore space determine the formation and extent of the firn aquifer. READ MORE

  4. 3. Subsurface characterization of the Lund Sandstone – 3D model of the sandstone reservoir and evaluation of the geoenergy storage potential, SW Skåne, south Sweden-merged

    University essay from Lunds universitet/Geologiska institutionen

    Author : Erik Aldenius; [2019]
    Keywords : Energy storage; CAES; geothermal energy; Lund Sandstone; renewable energy; geoenergy; Earth and Environmental Sciences;

    Abstract : In order to decrease the dependence on fossil fuels it is of paramount importance that renewable sources are used as effectively as possible. Therefore it is necessary to store excess energy when supply is higher than de-mand. One way to do so is by storing the energy as compressed air in a porous aquifer. READ MORE

  6. 5. Application of GALDIT index in the Mediterranean region to assess vulnerability to sea water intrusion

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tracy Zaarour; [2017]
    Keywords : aquifer; Physical Geography and Ecosystem analysis; Sea Water Intrusion SWI ; Vulnerability Index VI ; GALDIT VI; Groundwater; GEM; Earth and Environmental Sciences;

    Abstract : GALDIT is a Vulnerability Indexing (VI) methodology that uses ranges, ratings and weights developed as a preliminary decision support tool to predict groundwater areas prone to Sea Water Intrusion (SWI). It has been only applied on porous coastal aquifers to date, in Mediterranean coastal regions, where SWI has become a growing problem. READ MORE
