1. Quantifying pollutant spreading and the risk of water pollution in hydrological catchments A solute travel time-based scenario approachDetta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University
Sammanfattning : The research presented in the thesis develops an approach for the estimation and mapping of pollutant spreading in catchments and the associated uncertainty and risk of pollution. The first step in the approach is the quantification and mapping of statistical and geographical distributions of advective solute travel times from pollutant input locations to downstream recipients.

Sammanfattning : In this PhD thesis we prove some properties of elliptic equations in connection with periodic homogenization. We mainly study the stationary linearized elasticity system. This thesis consists of five papers complemented with a short introduction.The first paper concerns some elliptic equations on a domain with oscillating boundary. LÄS MER
