  1. 1. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Haoyang Dong; [2022]
    Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

    Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

  3. 2. Drivers of topsoil saturated hydraulic conductivity in three contrasting landscapes in Kenya

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : David Falk; [2021]
    Keywords : Infiltrability; mixed effects model; Kenya; land degradation; restoration; trees;

    Abstract : Markförsämring i tropiska regioner kan ha förödande konsekvenser för vattentillgänglighet. Vattenkvalité och kvantitet är oerhört viktiga för lokalbefolkningar och är grundförutsättningar för socioekonomisk utveckling då stora delar av befolkningen i många tropiska länder är direkt beroende av jordbruk och boskapshållning för sin inkomst.

  4. 3. Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Lisa Risby; [2020-07-08]
    Keywords : short duration hydraulic tests; hydraulic conductivity; radius of influence; infiltration; heterogeneity; confined and unconfined aquifer;

    Abstract : This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic) conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitate the identification of main water-bearing units (e.g. READ MORE

  5. 4. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D

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

    Author : Alexander Bergman; Mire Persmark; [2020]
    Keywords : Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Abstract : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. READ MORE

  6. 5. Evaluating the effective oxygen diffusion coefficient in blends of till and green liquor dregs (GLD) used as sealing layer in mine waste covers

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Anna Virolainen; [2018]
    Keywords : Oxygen diffusion; green liquor dregs; mine waste; covers; sealing layers;

    Abstract : Dry covers can be used to limit the generation of acid mine drainage from sulphidic mine waste exposed to air and water. For the covers to act efficiently a high degree of saturation should be maintained in the cover, as the diffusion of oxygen is substantially reduced in water compared to that in air. READ MORE
