Haoyu Wei’s research work focuses on stormwater quality issues from the prospect of evaluating interactions between stormwater from different sources and the use of conventional urban drainage system (e.g. gully pots). Current gully pot maintenance strategies lack clear aims and a robust evidence base against which their performance can be benchmarked. The discussions on the optimisation of gully pot maintenance operations require further understanding on the net sediment accumulation as well as their physicochemical properties. Haoyu’s research work aims at evaluating impacts of changes in rainfall patterns on gully pot sediment scouring and the influences of various factors on the long-term accumulation of sediments and associated contaminants in gully pot system. The assessed factors include key anthropogenic practices such as seasonal activities, land-use types, traffic conditions, environmental measures and gully pot configurations. The thorough characterisation of gully pot sediments (including metals, organic contaminants, physicochemical and toxicological properties) also contributes to the discussions to develop robust gully pot waste disposal and management strategies.
Haoyu joined the Urban Water Engineering team at LTU in February 2019. Previously, Haoyu accomplished his Bachelor’s education in Wuhan University, China, with a degree on Water Quality Science and Technology. He achieved his Master’s degree in Water Resources Engineering at Lund University, Sweden. In his master’s thesis work, he built up a three-dimensional conceptual model of a contaminated site in Alingsås, Sweden. This thesis work serves as a part of the “MIRACHL” project in the Division of Engineering Geology, Lund University.
