  1. 6. Physico-chemical evaluation of the water quality in Rocha River: A qualitative and comparative analysis including aspects of social and environmental factors

    University essay from Lunds universitet/Teknisk geologi

    Author : Stina Jacobson; Ida Sekizovic; [2019]
    Keywords : Cochabamba; Rocha River; water quality analysis; water pollution; wastewater; regulations; ICO-index; Hec-RAS; minor field study; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : In this study, a physico-chemical analysis of the Rocha River was performed during the beginning of the rainy season 2018 in order to examine the current state of the water quality in the river at six different locations. The river, located in the Cochabamba department, Bolivia, was examined from upstream in Sacaba to downstream in Sipe Sipe. READ MORE

  3. 7. Paper-based flexible laminates tendency to curl

    University essay from Lunds universitet/Förpackningslogistik

    Author : Clémentine Muller; [2018]
    Keywords : flexible laminates; paper; curl; relative humidity; temperature; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : The main purpose of this study is to assess the impact of environmental conditions on paper-based flexible laminates tendency to curl. Any deviation in flatness may indeed affect materials processability. READ MORE

  4. 8. Regional Regression Models of Mean Annual Streamflow and Design Flow in a Tropical Region of Colombia.

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Anisa Zigaf Elfellah; Amanda Eriksson; [2018]
    Keywords : mean annual streamflow; extreme flow; design flow; regional regression model; ungauged watershed; hydrological homogeneous region; Gumbel distribution; Technology and Engineering;

    Abstract : A responsible and sustainable water resources management is important. It is also crucial to take the presence of watercourses into account during design of hydraulic structures such as small dams and bridges. Doing this requires knowledge of estimates of annual streamflow and extreme flows to be used for design purposes. READ MORE
