1. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data
Master-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. LÄS MER
2. Modelling the risk of rainfall events leading to momentary pollution levels exceeding maximum allowed concentrations - A Swedish case study of urban runoff in the Fyris river
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The purpose of this study was (1) to study the proportion (X) of the flow in a watercourse that consists of urban runoff during a rain event and (2) to evaluate the risk that a few chosen pollutants, transported by urban runoff, exceed the maximum allowed concentration in the watercourse according to the environmental quality standards (MAC-EQS). The Fyris river in Uppsala, Sweden, was selected as a case study. LÄS MER
3. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

4. Avskiljning av naturligt organiskt material vid konstgjord grundvattenbildning i Uppsalaåsen
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Uppsalas dricksvattenförsörjning baseras på konstgjord grundvattenbildning som innebär att vatten från Fyrisån får rinna ned till grundvattnet från infiltrationsbassänger. Detta examensarbete syftar till att undersöka vad som händer med naturligt organiskt material (NOM) i Uppsalaåsen vid konstgjord grundvattenbildning. LÄS MER
5. Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes. LÄS MER
