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

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Sammanfattning : 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. LÄS MER

5. 4. Characterization and modeling of hydrology and climatology in paramo ecosystems in Colombia : A study of the paramos and climate change impact on these ecosystems as a water resource

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Lovisa Nilsson; Julia Tholander; [2022]
   Nyckelord :paramo; hydrology; climate change; precipitation; discharge; modeling; characterization; HBV; ENSO; paramo; hydrologi; klimatförändringar; nederbörd; avrinning; modellering; karaktärisering; HBV; ENSO;

   Sammanfattning : Paramos are unique ecosystems situated in the tropical Andes at an elevation of 2800-4800 meters above sea level. They are home to a variety of endemic species and have a great water regulating capacity and supply around 80 % of the population in Colombia with freshwater. LÄS MER

7. 5. Effects of afforestation of agricultural land on the water balance in Ethiopian Highlands

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Mwala Silumesi; [2022]
   Nyckelord :acacia decurrens; aquaCrop Mode; afforestation; water balance; teff;

   Sammanfattning : In this study, I examined how land use change affects the partitioning of water and how soil-plant interactions are impacted by yearly rainfall at a stand scale. Even though many studies have been conducted to evaluate the extent of land use change and the economic impacts, few have attempted to study the rapid farmer-driven afforestation with Acacia decurrens and also disaggregated dry, normal and dry seasons at stand scale.
