  1. 1. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  3. 2. Construction and development of a low-cost hyperspectral imaging system

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nikita Grigoriev; [2022]
    Keywords : Hyperspectral Imaging; Pushbroom;

    Abstract : Quantification of spectral data is of great interest in many fields of science, since it can provide further insight into other properties of an object. However, traditional cameras are usually made to image the world in a similar fashion as to how we see it, wherefore they are usually not fit to record nor measure further spectral information.

  4. 3. Investigation of groundwater resources - A case study in north-west Tanzania using remote sensing analysis and groundwater simulation

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Cecilia Lundqvist; [2017]
    Keywords : Groundwater resources; Remote sensing; Hydrologic budget; MOD- FLOW; Chonyonyo; Tanzania; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Globally 884 million people depend on unsafe drinking water, of which 159 million depend on untreated surface water (WHO, 2017). In Tanzania 44% of the popula- tion lack access to safe drinking water (WaterAid, 2017). READ MORE

  5. 4. Estimating Aquifer Transmissivity based on Streamflow Records using an Analytical Approach in Kilombero Valley, Tanzania

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Jamila Tuwa; [2016]
    Keywords : ;

    Abstract : Streamflow recession techniques have been useful in estimating aquifer hydraulic propertiesthat are not easily measured, but are important for the hydrologic responses of catchments.Compared to other hydraulic properties, aquifer transmissivity (T) is a key parameterproviding insight on groundwater development at a local and regional scale.

  6. 5. Hydrological modeling enhancement using GIS : An improved topographic wetness index for wetland detection

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Patricia Rull; [2016]
    Keywords : Blue spots; digital dams; culverts; hydrologically enforced DEM; topographic wetness index; TWI; soil-topographic wetness index; STI; wetland detection;

    Abstract : Hydrological modeling, like runoff modelling for flood prevention, is based on digital elevation models (DEMs). The fact that the DEMs do not represent existing road culverts can lead to considerable hydrological misinterpretations. READ MORE
