  1. 36. Glacial lakes in the Torneträsk region, northern Sweden, are key to understanding regional deglaciation patterns and dynamics

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Karlijn Ploeg; [2022]
    Keywords : deglaciation; glacial geomorphology; LiDAR; glacial lakes; Torneträsk;

    Abstract : The prospect of sea level rise due to melting ice sheets affirms the urgency of gaining knowledge on ice sheet dynamics during deglaciation. The Fennoscandian Ice Sheet serves as an analogue, whose retreat can be reconstructed from the geomorphological record. READ MORE

  2. 37. Developing a Rainfall-Runoff Routing Model using  Spatially Distributed Travel Times : Modelling a Cloudburst Event in an Urban Catchment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sara Ekeroth; [2022]
    Keywords : Excess rainfall; Runoff routing; Cloud burst; Pluvials; GIS; ArcPy; Effektiv nederbörd; Avrinningsmodell; Skyfall; Pluviala översvämningar; Geodata; ArcPy;

    Abstract : The future holds challenges for urban areas when it comes to handling pluvial floodings, occurring when the rainfall intensity exceeds both the man-made and natural infiltration and drainage capacity. To gain understanding of the effects and needed measures, tools for modelling the urban response to events such as cloudbursts are needed. READ MORE

  3. 38. Exploring Urban Rainwater Harvesting in the city of Madrid applying GIS based MCDA expert tools

    University essay from KTH/Urbana och regionala studier

    Author : Silvia Börjesson Ballesteros; [2022]
    Keywords : Rainwater Harvesting Systems; Pond Harvesting Systems; Nature-based facilities; Climate Change Adaptation; MCDA; ArcGIS; Madrid; Spain; Sustainable water management solutions; Regnvattenuppsamlingssystem; naturbaserade anläggningar; klimatanpassning; urban resiliens; MCDA; ArcGIS; Madrid; Spanien; lösningar för hållbar vattenhantering;

    Abstract : Due to climate change, water resources’ scarcity and distribution variability have generated a growing interest in sustainable water management in recent years. In addition, the growing interest in implementing nature-based solutions for urban resilience leads to the development of decentralized water supply systems such as rainwater harvesting systems (RWHS) as a complementary resource to conventional centralized water supply systems.

  4. 39. Numerical simulations of pore pressure on concrete buttress dams

    University essay from KTH/Betongbyggnad

    Author : Mohammed Abdi; Dimitirios Ntzimanis; [2022]
    Keywords : Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

    Abstract : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. READ MORE

  5. 40. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Linus Holgersson; [2022]
    Keywords : Phosphorus; Two-stage ditch; Equilibrium phosphate concentration; Phosphorus retention; Eutrophication; Soluble reactive phosphorus;

    Abstract : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. READ MORE
