3D Numerical Modelling of Sediment Transport under Current and Waves
Afzal, Mohammad Saud (Master thesis, 2013)The sediment transport module of REEF3D is used to calculate the scour and the deposition pattern for abutment, pier and contraction under constant discharge and for pier under waves. The time development of scour for all ... -
Assessing Stability of Coastal Bluffs Due to Combined Actions of Waves and Changing Ambient Temperatures in the Arctic
Schneider, Agnes Katharina (Master thesis, 2017)The Arctic coastal zone is characterized by high erosion rates, which are on average 0,5 m/year but can reach up locally to 25 m/year and therefore endanger coastal infrastructure. Additionally, the global warming takes ... -
Modelling the seasonal variations of soil temperatures in the Arctic coasts
Islam, Mohammad Akhsanul; Lubbad, Raed; Ghoreishian Amiri, Seyed Ali; Isaev, Vladislav; Shevchuk, Yaroslav; Uvarova, Alexandra Vladimirovna; Afzal, Mohammad Saud; Kumar, Avinash (Peer reviewed; Journal article, 2021)The soil temperature within the Arctic coasts within the continuous permafrost is not widely measured; the temporal and spatial resolutions of the measured temperature observations are relatively high. In this study, we ... -
Numerical Simulation of Free-Surface Waves past Two Semi-Submerged Horizontal Circular Cylinders in Tandem
Ong, Muk Chen; Kamath, Arun; Bihs, Hans; Afzal, Mohammad Saud (Journal article; Peer reviewed, 2017)Two-dimensional (2D) numerical simulations are performed to investigate free surface waves past two semi-submerged horizontal circular cylinders in tandem. The 2D simulations are carried out by solving the Unsteady ... -
A probabilistic model of coastal bluff-top erosion in high latitudes due to thermoabrasion: A case study from Baydaratskaya Bay in the Kara Sea
Islam, Mohammad Akhsanul; Lubbad, Raed; Afzal, Mohammad Saud (Peer reviewed; Journal article, 2020)Arctic coastal erosion demands more attention as the global climate continues to change. Unlike those along low-latitude and mid-latitude, sediments along Arctic coastlines are often frozen, even during summer. Thermal and ... -
Three-dimensional numerical modeling of local scour around a non-slender cylinder under varying wave conditions
Ahmad, Nadeem; Afzal, Mohammad Saud; Bihs, Hans; Arntsen, Øivind Asgeir (Chapter, 2015)The three-dimensional numerical model REEF3D is used to simulate the detailed flow field and sediment transport around a non-slender cylinder under regular waves. The location of the free surface is calculated with the ...
