  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.

  2. 2. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Feixiong Qu; [2021]
    Keywords : ;

    Abstract : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. READ MORE

  3. 3. Urban Flooding in Ljungby Municipality and the Effectiveness of Blue-green Mitigation Measures Using the Software SCALGO Live

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Bayan Taleb; [2021]
    Keywords : Blue-green solutions; climate change; hydraulic modelling; urban flooding.; Earth and Environmental Sciences;

    Abstract : En av konsekvenserna av klimatförändringen är en ökning av extrema regn. Kraftigt regn har blivit vanligare de senaste åren, troligen kommer nederbörden fortsätta att öka under kommande åren, säger forskarna. Den 10 augusti 2020, föll ett kraftigt regn i Ljungby stad som orsakade många översvämningar i privata och publika områden. READ MORE

  4. 4. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    University essay from Lunds universitet/Teknisk geologi

    Author : Simon Kreipl; [2021]
    Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

  5. 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; 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
