Currently, we can propose several stormwater-related master's thesis projects to be carried out within the framework of various research projects led by Urban Water Engineering at Luleå University of Technology, partly in collaboration with municipalities.
Hydrological function of green roofs: We have run-off data from green roofs in Kiruna and Umeå, Sweden. The data can be evaluated and the hydrological function of green roofs in cold climates be described in more detail. Drainage modeling can be included.
(a) evaluation of the function : Luleå University of Technology (LTU) evaluates stormwater bioretention test facilities in Stockholm, Sundsvall and Malmö, Sweden. We investigate teh treatment of metals, nutrients, organic micro-pollutants etc. There are several opportunities for writing degree projects about these facilities. Sampling of the facilities is in progress, but the student is expected to participate in sampling opportunities and actively contribute to the sampling. The project is led by LTU in collaboration with the respective municipalities.
(b) modeling treatment processes: Stormwater biofilters treat urban runoff through various processes including sedimentation or physical filtration of particulate pollutants, sorption, volatilization, biodegradation, photodegradation and accumulation in plants. Better understanding the role of such process in treatment performance can lead to improvements in system design. We are looking for a student who would like to work on modeling the treatment and fate of micropollutants (organic pollutants and metals) in stormwater biofilters; model results will be compared to experimental results from previous field and laboratory studies in order to gain a more process-based understanding of experimental observations of treatment performance, while identifying the limits of a given theoretical frame work and possible improvements to models.
