  1. 1. A simple model for wave generation under varying wind condition

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Alemayehu Dula Shanko; [2016]
    Nyckelord :Model; Hanson Larson evolution model; growth and decay; wave height; wave period; Technology and Engineering;

    Sammanfattning : The Hanson Larson evolution model assumes that wave height grows or decays from an initial condition towards an equilibrium wave height through a simple exponential growth. The model uses wind input data, fetch length and depth measurements. LÄS MER

  3. 2. Hydraulics Studies In Port Conception

    Master-uppsats, KTH/Marina system

    Författare :Sophie Hermite; [2015]
    Nyckelord :Maritime works; hydraulic studies; LNG - Wave propagation; wind fetch; shoaling;

    Sammanfattning : In the Maritime Works Engineering department of Saipem, studies have been carried out to design an extension to an existing LNG export facility. The scope of work comprises the design of a jetty on piles. For this purpose, wave propagation and ship mooring computations have been performed, as well as shore protection and abutment studies.

  4. 3. Hindcast of the wave climate in Öresund : modelling of wave climate over 50 years using WAM with wind measurements input

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Laury Renac; Sara Schömer Ericsson; [2014]
    Nyckelord :Wave climate modelling; WAM; Öresund; Earth and Environmental Sciences;

    Sammanfattning : Öresund is a very dynamic economic area with numerous projects, there is a great need of a deeper understanding of the wave climate. The wave measurements currently available are scarce and they do not cover the whole area. LÄS MER

  5. 4. Modelling near ground wind speed in urban environments using high-resolution digital surface models and statistical methods

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Lars Johansson; [2012]
    Nyckelord :Geographic Information System; spatial variability; GIS; digital surface model; wind speed; urban geometry; geomatics; geography; urban climate; physical geography; geografi; naturgeografi; geomatik; stadsklimat; bebyggelsegeometri; vindhastighet; digital höjdmodell; rumslig variation; geografiska informationssystem; Earth and Environmental Sciences;

    Sammanfattning : Wind is a complex phenomenon and a critical factor in assessing climatic conditions and pedestrian comfort within cities. This master’s thesis attempts to quantify and model the relationship between near ground wind speed and urban geometry using two-dimensional raster data and variable selection methods based on Multiple Linear Regression.

  7. 5. Uncertainties introduced by the ocean surface when conducting airborne lidar bathymetry surveys

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Torbjörn Karlsson; [2011]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A method for investigating how the ocean surface aects the accuracy of Airborne Lidar Bathymetry surveys, (ALB), due to environmental conditions, was developed. Computer graphic techniques were examined and utilized for construction of realistic ocean surfaces. LÄS MER
