1. 16. Olika trädsubstrats vattenhållande kapacitet och dräneringsförmåga : en jämförande studie

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Michael Barone; [2021]
   Keywords : ekosystemtjänster; träd; växtbäddar; dagvatten; skelettbäddar; substrat; biokol; pimpsten; dränering; fältkapacitet;

   Abstract : I takt med klimatförändringarnas framfart, med bland annat högre temperaturer och mer extrema skyfall, riktas det alltmer fokus på de reglerande ekosystemtjänster som träden kan erbjuda oss i det urbana landskapet. För att träden ska kunna leverera de ekosystemtjänster som efterfrågas krävs att de når en hög ålder och därmed också större volymer i krona och stam. READ MORE

3. 17. Sustainability assessment of sanitation systems in El Alto, Bolivia : A pre-study

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Malin Smith; [2020]
   Keywords : Sustainable sanitation; peri-urban; urine-diverting dry toilet; waste stabilization pond; stakeholder; Hållbar sanitet; peri-urban; urinsorterande torrtoalett; stabiliseringsdamm; intressent;

   Abstract : The Sustainable Development Goal (SDG) Target 6.2 aims at providing access to adequate and equitable sanitation and hygiene for all and to end open defecation by 2030. Yet, 47 % of the population in Bolivia lacked access to basic sanitation services in 2012. READ MORE

4. 18. Sensitivity analysis of pluvial flood modelling tools for dense urban areas : A case study in Lundby-Lindholmen, Gothenburg

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Johanna Eriksson; [2020]
   Keywords : Flood Modelling; MIKE FLOOD; Sensitivity Analysis;

   Abstract : As a result of the global climate change, extreme precipitation is occurring more frequently which increases the risk of flooding, especially in urban areas. Urbanisation is widely discussed regarding urban flooding where an increase of impervious surfaces limits the infiltration and increases the surface runoff. READ MORE

5. 19. Sensitivity analysis of grate inlet representation and a comparison of two coupled hydraulic models for urban flood simulation

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Daniel Lundqvist; [2020]
   Keywords : Urban flood models; 1D-2D coupled models; MIKE FLOOD; FLO-2D; inlet grates; manholes;

   Abstract : Urban flood models are an important tool in designing and analyzing municipalities sewer drainage systems and predicting the effect of potential extent and depth of future floods. In urban areas, coupled 1D-2D flood models are particularly useful as they can represent the surface- and sewer system and their interactions. READ MORE

6. 20. Using X-band Radar with a Neural Network to Forecast Combined Sewer Flow - A case study in Lund

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Filip Faust; Per Nelsson; [2020]
   Keywords : X-band radar; neural networks; combined sewer; forecasting; urban hydrology; Lund; Technology and Engineering;

   Abstract : This study aimed to forecast combined sewer flow into a wastewater treatment plant in Lund, Sweden by using uncalibrated X-band radar data with a neural network. Neural networks have proved themselves useful in the field of forecasting as they can solve multiple kinds of problems and recognise patterns in the data (Alemu et al. READ MORE
