  1. 1. Flood mitigation at catchment scale: assessing the effectiveness of constructed wetlands

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Elin Ekström; [2023]
    Keywords : Nature-based solutions; wetlands; catchment; performance indicators; flood management; hydrological modeling; SWAT; Naturbaserade lösningar; våtmarker; avrinningsområde; nyckelindikatorer; översvämningshantering; hydrologisk modellering; SWAT;

    Abstract : Considering the potential for natural wetlands to store and retain water in the landscape,restored and constructed wetlands are increasingly implemented as Nature‐BasedSolutions (NBS) to mitigate downstream flooding. However, there is a frequent lack ofknowledge of the performance of NBS, and particularly wetlands, and how to best selectperformance indicators to measure their effectiveness. READ MORE

  3. 2. What has happened on Swedish mires? The effects of drainage on vegetation changes over recent decades

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anna Ljungqvist; [2022]
    Keywords : peatlands; mires; bogs; fens; sweden; vegetation; plant ecology; time trend; data; nfi; nils; climate change; global warming; mosses; sphagnum; afforestation; trees; wetland; presence; coverage; drainage; ditch;

    Abstract : As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. READ MORE

  4. 3. A preliminary study of evidence-based tool for wetland optimization - A case study using QSWAT+

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Victoria Truong; Sebastian Huynh; [2022]
    Keywords : QSWAT ; SWAT ; QGIS; Hydrology; Wetlands; Technology and Engineering;

    Abstract : This Master´s thesis is a part of the Ecodiver project, conducted by the Water department at LTH. The purpose of this study is to review the open-source software QSWAT+ as a plugin in QGIS, to be able to develop an evidence-based tool for optimization of wetlands. READ MORE

  5. 4. Mobility, habitat selection and population connectivity of Lycaena helle in central Sweden : implications for conservation

    University essay from SLU/Dept. of Ecology

    Author : Hanna Modin; [2018]
    Keywords : Lycaena helle; violet copper; Lepidoptera; Lycaenidae; mobility; dispersal; resource selection function; habitat selection; connectivity; metapopulation; stepping stone;

    Abstract : Lycaena helle is an endangered butterfly that is mainly threatened by habitat degradation and fragmentation. For all species with a fragmented distribution, knowledge about mobility, habitat requirements and connectivity is key to developing successful conservation strategies. READ MORE

  6. 5. Water budget estimation on a data limited wetland : The case of the Ciénaga Grande de Santa Marta, Colombia

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Anna Hylin; [2014]
    Keywords : Data limited wetland; water budget; Ciénaga Grande de Santa Marta;

    Abstract : At the end of the 20th century, the combination of climatic and anthropogenic events resulted in hyper salinity conditions in the coastal wetland Ciénaga Grande de Santa Marta (CGSM), Colombia. Although salinity concentrations are generally related to the type and quantity of water entering and exiting a wetland and to its internal hydrological dynamics, there have been no up to date hydrological studies on the CGSM.
