1. 11. 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 landskapslära

   Author : Jimmy Olsson; [2019]
   Keywords : pluvial flooding; flood modelling; 1D-2D modelling; MIKE FLOOD; MIKE 21; MIKE URBAN; storm movement; temporal variability; hyetograph; design storm; Chicago Design Storm; CDS-rain; pluviala översvämningar; översvämningsmodellering; 1D-2D modellering; MIKE FLOOD; MIKE 21; MIKE URBAN; molnrörelse; hyetograf; typregn; Chicago Design Storm; CDS-regn;

   Abstract : 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

3. 12. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic study

   University essay from Luleå tekniska universitet/Arkitektur och vatten

   Author : Per-Albin Norman; [2018]
   Keywords : Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

   Abstract : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. READ MORE

4. 13. Urban flood modelling : a GIS based approach in Lomma, Skåne region

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Michael Araya Ghebremariam; [2017]
   Keywords : Physical Geography and Ecosystem analysis; Digital Elevation Model; Single flow direction algorithm; Deterministic eight-node D8 algorithm; Multiple flow direction algorithm; Triangular Form Based Multiple Flow algorithm TFM ; Earth and Environmental Sciences;

   Abstract : Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. READ MORE

5. 14. Hydraulic and Hydrodynamic Stormwater Model for the Västanfors Area of the Municipality of Fagersta, Sweden: Climate Change Impacts and Future Stormwater Management

   University essay from KTH/Mark- och vattenteknik

   Author : Anne Marie Girtz; [2017]
   Keywords : ;

   Abstract : Global temperatures and frequency of extreme weather events have increased over the last decade, with 2015 globally the warmest year on record. Future climate models are consistent with this trend, predicting larger year-to-year variations in precipitation, more precipitation in larger single events, and more frequent extreme events.

6. 15. A case study of runoff coefficients for urban areas with different drainage systems

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Christine Thomas; [2017]
   Keywords : 1D Hydraulic modelling; avloppsteknik; environmental engineering; stormwater; vattenförsörjningsteknik; water Engineering; Runoff Modelling; SuDS; Urban Runoff; Effective Impervious Area; Technology and Engineering;

   Abstract : According to the United Nations, half of humanity now lives in cities. In recent years, many countries have seen a rise in the number of and intensity of heavy rainfall events due to the effects of climate change. The consequences of urban flooding in such a context can vary between just causing mild discomfort to tremendous devastation. READ MORE
