  1. 1. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Elin Brandt Korall; [2024]
    Keywords : Wetlands; GIS; Restoration; Rewetting; Ecology; LONA; Habitats Directive; Natura 2000; Nature conservation; Våtmarker; GIS; Geografiska informationssystem; Restaurering; Återvätning; LONA; Art- och Habitatsdirektivet; Natura 2000; Naturvård;

    Abstract : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. READ MORE

  2. 2. Data Assimilation for Systems with Multiple Timescales

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Dan Vicente Ihanus; [2023]
    Keywords : Mathematics; Partial Differential Equations; Numerical analysis; Data assimilation; Numerical weather prediction; Ensemble Kalman Filter;

    Abstract : This text provides an overview of problems in the field of data assimilation. We explore the possibility of recreating unknown data by continuously inserting known data into certain dynamical systems, under certain regularity assumptions. READ MORE

  3. 3. Growing on the roof : But in what? Examing substrates/growing media for rooftop farming

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Mikael Brocki; [2023]
    Keywords : urban rooftop agriculture; URTA; green roof; substrate; growing medium; organic matter; compost; vegetable; crop; yield; lettuce; tomato; pore; pore-size distribution;

    Abstract : Urban Rooftop Agriculture (URTA) is a novel field within urban vegetable production, which can help create access to local food in a rapidly urbanizing world. For these systems to succeed, it is vital to implement a proper choice of substrate/growing medium (SGM). READ MORE

  4. 4. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Markus Hellberg Mediaa; [2023]
    Keywords : Discontinuous Galerkin; Korteweg-de Vries; Conservation Laws; Partial Differential Equations; Numerical methods; Higher order spatial derivative; Heat Equation; Burgers’ Equation; Collocation; Lobatto Gauss Legendre; Stiffness; Nodal Approximation; Finite Volume; Finite Element;

    Abstract : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. READ MORE

  5. 5. Shallow Water : A comparison between hydraulic measurements and numerical models

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Dan Nilsson; [2023]
    Keywords : CFD; Surface Roughness; Manning coefficient; Hydropower;

    Abstract : In the near future hydropower will be used to regulate intermittent energy sources, shallow water ways can then occur in close proximity to the power plants, where the bottom often consists of stones in a similar length scale as the water depth. The idea of this project, which has been initiated by Vattenfall R\&D, is to compare experimental measurements in a laboratory environment with numerical simulations with CFD, this to find a way to represent roughness structures where there is low relative submergence.
