Funding: Technische Universität Braunschweig, Period: 2021–2024, Responsible: Aberle, Jochen

Type	Competitive R&D&I project
Acronym	IHATEC-II
Start date	01/12/2021

Description	The turbulent flow created behind ship propellers can erode the alluvial bottoms of navigable rivers, canals and coastal ports, causing damage to the bed morphology and port structures. This project aims to develop new approaches to analyze the interaction between ships and port infrastructures, in order to anticipate and counteract erosion damage. The characteristics of propeller jets, the propagation of flows and their impacts on granular walls and bottoms are studied through measurement campaigns, laboratory tests and numerical simulations. A physical scale model of the port will also be built at the Leichtweiß Institute and the hydraulic loads, noise and the effect on the docks will be analyzed. In addition, simulations from the Institute of Fluid Dynamics at TU-Hamburg will be included to analyze the interactions with different propulsion systems. This will allow a better understanding of the effects on morphological development and harbor shoaling.
