1. 1. Surface Runoff on Green Urban Areas : A study on driving forces behind surface runoff generaiton

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Erik Nilsson; [2023]
   Keywords : Surface runoff; Hydrus; Urban green area; Soil Moisture;

   Abstract : Recent flooding events, such as the one in Germany 2021 have caused irreversible damages to infrastructure and lives. The aftermath of events like these have underlined the importance of an accurate risk management by predicting them in urban areas. READ MORE

3. 2. The Influence of Infiltration Capacity and Antecedent Soil Moisture Conditions on Urban Pluvial Flooding

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Disa Barkefors; [2023]
   Keywords : Urban pluvial flood; 2D modelling; MIKE ; urban green area; soil moisture; Chicago Design Storm;

   Abstract : Urban pluvial floods occur during extreme rain events and both occurrence and magnitude of these floods are expected to increase. Preserving or constructing green areas in urban areas has been shown to mitigate and control these floods. READ MORE

4. 3. 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 landskapslära

   Author : Oskar Ahlstedt; [2022]
   Keywords : Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

   Abstract : 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

5. 4. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fanny Jeppsson Stahl; [2022]
   Keywords : Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

   Abstract : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.

6. 5. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Daniel Elfström; Max Stefansson; [2021]
   Keywords : cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

   Abstract : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. READ MORE
