1. 6. Assessment of Groundwater Flow to Lake Bolmen

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

   Author : Massimiliano Favaro; [2021]
   Keywords : Groundwater; modelling; MODFLOW; GMS; hydrogeology; Technology and Engineering;

   Abstract : This work reports the research and findings concerning the processes of groundwater flow and distribution to lake Bolmen in the Småland region, Sweden. The watershed of Bolmen is of high interest since it provides water for drinking and energy purposes, representing a resource of notable importance for the society of southern Sweden. READ MORE

3. 7. Dispersion of cement-based grout with ultrasound and conventional laboratory dissolvers

   University essay from KTH/Byggvetenskap

   Author : Antranik Karamanoukian; [2020]
   Keywords : ultrafine cement grout; microfine cement grout; dispersion; additives; ultrasound dissolver; laboratory dissolver; ultrafint cementbruk; mikrofin cementbruk; dispergering; tillsatser; ultraljud apparat; laboratorieblandaren;

   Abstract : In any underground facilities especially tunnels, it is essential to seal the area against water ingress and leakage of reserved materials. Grouting is a common method used to seal rocks around tunnels, successful grouting reduces the duration and cost of the construction, guarantees better working environment and higher safety, minimizes the maintenance and most important decreases the corresponding environmental hazards significantly.

4. 8. Fracture characterization in magmatic rock, a case study of the Sosa-dyke (Neuquén Basin, Argentina)

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Nilsson Jim; [2020]
   Keywords : dyke; magmatic intrusion; fractures; Sosa dyke; permeability; intrusion; magmatisk intrusion; sprickor; Sosa intrusionen; permeabilitet;

   Abstract : There are many examples worldwide were fossil magmatic intrusions influence the local water and energy supply. Due to that intrusions can act as a conductor and a reservoir, but also as a barrier for fluids and gases in the ground. The decisive feature between conductor or barrier in an intrusion is its fracture network. READ MORE

5. 9. X-ray imaging of water flow through soil

   University essay from SLU/Dept. of Soil and Environment

   Author : Lorenzo Garbari; [2020]
   Keywords : infiltration; tomography; soil structure; soil porosity; wetting front; x-ray;

   Abstract : In this study a laboratory experiment on preferential flow was conducted with the aim to quantify the importance of water repellency, soil structure and irrigation rate on water infiltration into soil. To do so, the study was conducted as follows: (a) comparison between the wetting fronts of the irrigations done on the same sample; (b) the tortuosity of the wetting fronts, this was analysed calculating a tortuosity index; (c) the average infiltration velocity and (d) a visual comparison between the 3D images.

6. 10. Evaluation of "GIN method" at Two fans of City banan project in Stockholm

   University essay from KTH/Jord- och bergmekanik

   Author : Mehran Neshati Sani; [2015]
   Keywords : grouting; GIN method; cement; jacking; penetration; pressure; volume intake;

   Abstract : An underground installation with too much inflow can lead to dangerous consequences for around environment, therefore a well-sealed construction results in appropriate inflows. To mitigate movement of ground water table in underground constructions, it is necessary to seal the rock mass by grout injection. READ MORE
