1. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. READ MORE

2. Sensitivity analysis of a generic urban flow model : 2D modelling with empirical hyetographs and CDS rain
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Severe flooding events in recent years have underlined the importance of accurate hydrological modelling in urban areas. There are many important parameters relating to both the rainfall distribution and properties of the land on which the rain falls that controls the impacts of the rain event. READ MORE

3. Implementation of Citizens’ Observations in Urban Pluvial Flood Modelling
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Damages caused by urban pluvial floods are believed to increase due to climate change and urbanization as more citizens are impacted in densely populated cities and extreme rainfalls occur more frequently with higher intensities. To prepare cities for these calamities, urban pluvial flood models are created to provide knowledge about how an extreme rainfall event could inundate the studied city. READ MORE

4. A GIS-Based Method of Deriving Spatially Distributed Unit Hydrographs
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Prior to using hydraulic and spatially distributed modelling softwares, the theory of the unit hydrograph was a commonly used tool for modelling of surface and runoff water. While distributed models often provide detailed results from extensive calculation durations, the unit hydrograph have been questioned for simplifying the physical characteristics of the watershed modelled.

5. The influence of storm movement and temporal variability of rainfall on urban pluvial flooding : 1D-2D modelling with empirical hyetographs and CDS-rain
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Pluvial floods are formed directly from surface runoff after extreme rain events. Urban areas are prone to suffer from these floods due to large portions of hardened surfaces and limited capacity in the stormwater infrastructure. Previous research has shown that catchment response is influenced by the spatio-temporal behaviour of the rainstorm. READ MORE
