1. 1. 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.

3. 2. Dynamic streams in a pre-alpine catchment

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Andreas Sølberg; [2021-07-12]
   Keywords : Temporary streams; Streamflow; Stream mapping; Pre-Alpine catchment; Stream dynamics; Topographic wetness index; Upslope accumulated area;

   Abstract : This thesis aims to investigate the factors controlling the dynamics of temporary streams, i.e., streams that do not flow throughout the year. Temporary stream hydrology is a relative unexplored scientific field. READ MORE

4. 3. 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

5. 4. Implementation of Citizens’ Observations in Urban Pluvial Flood Modelling

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Fredrik Schück; [2021]
   Keywords : Calibration; Crowdsourcing; Citizen science; CDS-rainfall; 2D flood model; Spatial variability;

   Abstract : 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

6. 5. The influence of temporal rainfall distribution and storm movement on flood depth in urban pluvial cloud burst modeling

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Michael Henrich; [2019]
   Keywords : Pluvial flooding; cloud burst; flood modeling; MIKE 21; temporal distribution; storm movement; areal reduction factors; ARFs; hyetograph; design storm; CDS; Pluviala översvämningar; skyfall; översvämningsmodellering; MIKE 21; regnmönstrets tidsfördelning; molnrörelse; areal reduktion av nederbörd; ARFs; hyetograph; typregn; CDS;

   Abstract : Pluvial floods are the most difficult and to date least investigated phenomena in urban hydrology. While efforts are being made to increase the knowledge base concerning this type of flooding, a large part of the difficulty lies in the nature of the precipitation. READ MORE
