1. Modelling of Granular Materials
Sammanfattning : The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3.

2. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling
Sammanfattning : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. LÄS MER
3. Hydraulic Behaviour in an Activated Sludge Tank : From Tracer Test through Hydraulic Modelling to Full-Scale Implementation
Sammanfattning : Hydraulic behaviour in a large denitrifying activated sludge tank, located at the Rya Wastewater treatment plant (WWTP) in Göteborg Sweden, was investigated and optimized by using fullscale tracer test and hydraulic modelling. The Rya WWTP is a high loaded plant with a small footprint. Expansion of the site is limited due to several restrictions. LÄS MER
4. Flood Hazard Assessment in Data-Scarce Basins : Use of alternative data and modelling techniques
Sammanfattning : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. LÄS MER
5. Modelling, mapping and visualisation of flood inundation uncertainties
Sammanfattning : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.
