  4. 13. Hydrology of the karstic basin of Sprimont, Belgium : On the use of spectrofluorimetry and pharmaceutical substances as a supporting tool for hydrochemistry analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Romain Deleu; [2018]
    Keywords : hydrology; hydrogeology; karst; karstic; spectrofluorimetry; pharmaceutical; hydrochemistry; spring; losing stream; self-organizing map; SOM; Belgium; aquifer; undergound; stream; nitrogen; carbon; isotopes; contamination; risk; human impact; sewage; wastewater; tracer;

    Abstract : The strong variation in carbonate content of the geological formations in the basin of Sprimont, Belgium, implies different groundwater behaviours in the substratum. The existence of carbonated materials such as limestone is responsible for the existence of a well-developed karstic system restricted to the Carboniferous materials which has a strong impact on the local hydrology and hydrogeology.

    Author : Chengxiang Shi; [2018]
    Keywords : ;

    Abstract : Sweden is one of the leading countries in traffic safety, but pedestrians are vulnerable compared to other road users. “Vision zero” mission, which means no fatal or serious injury in road traffic system, has been the target of Sweden since 1997. As a result, more efforts should be put to reduce pedestrian accidents. READ MORE

  6. 15. Frequency analysis of heavy rainfall related to synoptic weather patterns in Kyushu Island, Japan by using the Self-Organizing Map (SOM)

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Norihiro Ohashi; [2018]
    Keywords : Heavy rainfall frequency; Self-Organizing Map; Pattern recognition; Meteorological fields; Technology and Engineering;

    Abstract : Recently heavy rainfall frequency in Kyushu Island, the southwestern part of Japan, during the rainy season, has been increasing due to possibly climate change, global warming. Owing to the recent increase of heavy rainfall frequency, natural disasters related to heavy rainfall including flooding and landslides have occurred and caused serious damages to infrastructures and human lives.
