4. 2. Environmental sanitation situation and solute transport in variably saturated soil in peri-urban Kampala

   Author : Robinah Kulabako; Roger Thunvik; Felix Mtalo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental Sanitation; Kampala; Modelling; Phosphorus transport; Shallow groundwater; Peri-urban; Vadose zone; Environmental engineering; Miljöteknik;

   Abstract : The environmental sanitation situation in Kampala’s peri-urban areas was reviewed and investigated through field studies, structured interviews with personnel from key institutions and administration of questionnaires to households in a selected peri-urban settlement (Bwaise III Parish).  In this settlement, specific field and laboratory measurements were undertaken so as to create a better understanding of the environmental sanitation situation, anthropogenic pollution loads and their transport and impact (with a focus on Phosphorus) in Kampala’s Peri-urban areas in pursuit of interventions for improving the environmental sanitation and protecting the shallow groundwater resource there.

5. 3. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

   Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

6. 4. Modelling of Turbulent Flow and Heat Transfer for Building Ventilation

   Author : Peng Shia-Hui; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; large eddy simulation; turbulent buoyant convection; ventilation performance assessment; purging flow rate; SGS modelling; ventilation flow; stochastic Markov chain model; turbulence modelling; LRN k-w model; two-equation models; building ventilation; transfer probability; transition regime; modified SGS buoyancy model; energy backscatter;

   Abstract : This thesis contributes to studies on the assessment of building ventilation performance and the development of turbulence models accounting for Low-Reynolds-number (LRN) effects and buoyant convection with heat transfer. Assessments of building ventilation performance are discussed with respect to indoor air distribution and passive contaminant dispersion. READ MORE

7. 5. In the Pipe or End of Pipe? : Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

   Author : Christoffer Carstens; Vladimir Cvetkovic; Auli Niemi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

   Abstract : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.
