2. 1. The Use of Press Archives in the Temporal and Spatial Analysis of Rainfall-Induced Landslides in Tegucigalpa, Honduras, 1980-2005

   Author : Elias Garcia-Urquia; Kristofer Gamstedt; José Cepeda; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; press archives; landslide database; urban landslides; critical rainfall intensity; antecedent rainfall; rainfall frequency contour lines; matrix method; landslide susceptibility index; Tegucigalpa; Honduras; Hurricane Mitch; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

   Abstract : The scarcity of data poses a challenging obstacle for the study of natural disasters, especially in developing countries where the social vulnerability plays as important a role as the physical vulnerability.  The work presented in this thesis is oriented towards the demonstration of the usefulness of press archives as a data source for the temporal and spatial analysis of landslides in Tegucigalpa, Honduras for the period between 1980 and 2005.

4. 2. Uncertainty Modelling in Hydrological Applications - Error Propagation Properties of Random Linear Systems

   Author : Jan Agerholm Høybye; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; floods; water quality; prediction uncertainty; differential equations; Stochastic hydrology; random functions; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Abstract : In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial conditions. READ MORE

5. 3. Climate and geographical influence on the performance of infiltration-based facilities for managing runoff – Temporal and spatial variability

   Author : Ivan Mantilla; Maria Viklander; Tone Merete Muthanna; Kelsey Flanagan; Vegard Nielsen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green infrastructure; hydrological performance; infiltration capacity; climatic pattern; saturated hydraulic conductivity; VA-teknik; Urban Water Engineering;

   Abstract : Climate change is expected to lead to more intense and severe rainfall events in the future, significantly increasing the risk of urban flooding. This change, characterized by spatial and temporal shifts in precipitation patterns, presents a challenge to the capacity of existing urban drainage systems, which may lead to higher runoff volumes than they were initially designed to handle.

6. 4. Influential factors in simulations of future urban stormwater quality : Climate change, progressing urbanization and environmental policies

   Author : Matthias Borris; Tone Merete Muthanna; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Climate change is regarded as one of the main future challenges implyingchanging hydrological conditions in urban areas. At the same time many urbanareas are expected to grow due to increasing population, which will most likelycause a higher level of urbanization. READ MORE

7. 5. Predicting the transport of Escherichia coli to groundwater

   Author : Emma Engström; Berit Balfors; Roger Thunvik; Nils-Otto Kitterød; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Groundwater contamination with pathogens poses a health risk worldwide. Predictive modeling could provide decision support for risk analysis in this context. This study therefore aimed to improve predictive modeling of the transport of Escherichia coli (E. coli) to groundwater. READ MORE
