  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. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martin Dahlin; [2022]
    Keywords : Streamflow information; Manning s estimation; rating curve; hydrographs; Vattenföring; avbördningskurva; hydrograf; Mannings ekvation;

    Abstract : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. READ MORE

  4. 3. Evaluation of Streamflow Predictions in an Ungauged Swedish Catchment : A Study of Håga River

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Hanna Pierrau; [2022]
    Keywords : Hydrology; Predictions in ungauged basins; Hydrological signatures; rainfall-runoff modelling; HBV; S-HYPE; hydrologi; uppskattningar i områden utan mätstation; hydrologiska signaturer; modellering; HBV; S-HYPE;

    Abstract : The Håga river, located west of the Swedish city Uppsala, is currently without a proper gauging station. Knowing the streamflow is nonetheless important to, for example, be able to calculate the nutrient transport in the river. READ MORE

  5. 4. Carbon dioxide dynamics in agricultural streams : Investigation of two streams draining catchments dominated by agricultural land

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Albin Bostner; [2020]
    Keywords : Carbon dioxide; dynamics; streams; agriculture; oversaturation; metabolic control; hyrdological control; Koldioxid; koldynamik; bäckar; jordbruk; övermättat; metabolisk kontroll; hydrologisk kontroll;

    Abstract : In recent years, streams draining agricultural land has been suggested to exhibit high carbon dioxide (CO2) concentrations when compared to streams draining other land-types. The transport of carbon from land to ocean is mainly occurring through the chain of inland waters, and with agricultural land today representing 40% of all continental area many of these inland waters are influenced by agricultural land.

  6. 5. 2D Effects of Geomorphology and Discharge on Hyporheic Exchange—a HEC-RAS Modelling Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Olivia Preston; [2020]
    Keywords : average hyporheic exchange velocity; water surface elevation; water surface concavity; hydrostatic head;

    Abstract : Hyporheic exchange is an ecologically and biogeochemically essential function of rivers and streams. One important driver of hydrostatic (hyporheic) exchange is gra- dients in the hydrostatic hydraulic head at the streambed. READ MORE
