1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER
2. Numerisk modellering av deformationer och portryck i en experimentdamm : Jämförelse mellan in-situmätningar och FE-simuleringar i PLAXIS 2D
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Under hösten 2019 har Vattenfall Research & Development byggt en experimentell jordfyllningsdamm i Älvkarleby med dimensionerna 20x15x4 meter. Delar av experimentdammen är konventionellt konstruerade och har installerats med geoteknisk utrustning som utgörs av bland annat inklinometrar och portrycksgivare. LÄS MER
3. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : 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. LÄS MER
4. Nanoplastic transport in soils by advection and bioturbation
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. LÄS MER
5. Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba
Kandidat-uppsats, Lunds universitet/Teknisk geologiSammanfattning : In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool. LÄS MER
