Project Title:

Impacts of climate change and urbanization on hydrologic processes over Hong Kong and the Pearl River Delta in South China

Project Description:

The main purpose of this study is to improve our understanding of the impacts of climate change and urbanization on hydrologic processes in Hong Kong (HK) and the Pearl River Delta (PRD) in South China. A larger goal is to advance our knowledge on the assessment of extreme hydrologic events (e.g. floods and droughts), with particular reference to climate change and urbanization impacts. In order to assess the impacts of climate change and urbanization on the hydrology of HK and the PRD, two systematic steps will be adopted in this project. The first step will involve impact assessment for the past, with analysis of three datasets:

  1. weather-station observations from the Hong Kong Observatory,
  2. weather-station observations from the China National Meteorological Information Center, and
  3. the USA NCEP/NCAR Reanalysis global weather data.
With knowledge of the past impacts, the second step will involve projections of future hydrologic impacts based on future climate scenarios from Global Climate Models.

Project Duration:

1 January 2011 – 31 December 2013

Project Significance:

This project will significantly contribute to research on the hydrologic impacts of climate change and urbanization in HK and the PRD, and for the world at large.

Results Achieved:

This research is supported by RGC General Research Fund (GRF)

Remarks on the Use of High Performance Computing Clusters:

HPC clusters are the essential facility for this project.
