Dr. Yesheng Lu has been awarded a Walter Benjamin Position by the German Research Foundation (DFG). The Walter Benjamin Program supports outstanding early career researchers in pursuing independent research projects and further developing their scientific careers.
As part of the funding, Yesheng will conduct a research project on “Vegetation-Turbulence-Sediment Coupling in Open Channel Flows – a Flume Study via Stereo Imaging Techniques“. The project investigates how aquatic vegetation influences riverbed dynamics, a key challenge in the restoration of rivers, flood management, and climate resilience. The aim is to improve our understanding of the vegetation-turbulence-sediment interactions and to develop improved predictive models for the design of more reliable river restoration measures.
We warmly congratulate Yesheng and wish him every success in his research.
Dieser TV-Beitrag wurde in der Wissenschaftssendung „W wie Wissen“ (ARD) ausgestrahlt. Er befasst sich mit nächtlichen Kaltluftströmungen die in relativ windstillen und wolkenfreien Sommernächten auftreten. Dabei fließt kältere Luft aus dem Umland in das Stadtgebiet hinein und sorgt für eine willkommene Abkühlung der sich tagsüber aufheizenden Stadt.
Am Beispiel von Untersuchungen für die Stadt Mannheim wird erläutert, wie durch eine überlegte Bebauung und der Anordnung von Freiflächen, Korridore für das Einfließen der Kaltluft geschaffen werden können, sodass die nächtliche Abkühlung möglichst vielen Stadtbewohnern zugutekommt.

Laboratory studies of nightly cold air drainage into the German city of Mannheim were performed. The incentive was to mitigate the urban heat island (UHI) effect which impacts dweller’s health and impairs sleep quality in hot summer nights. Colder air from the rural surroundings can cool down city air temperature and contribute to improved living and health conditions.
The movie shows the flow of simulated cold air as it was studied at scaled models for the present and the projected future state tailored to the improved intrusion of cold air flow into the city center. In subsequent film clips cold air flows in the present and future state are compared for various subareas and filmed from different perspectives.
