The Key Laboratory of Coastal Disaster and Protection (KLCDP) at Hohai University was founded by Ministry of Education, China in 2005, and consequently passed the government assessment in 2008. The laboratory operates on the policy that the director takes the full responsibility of administration under the supervision of academic committee, and it heavily relies on broader national and international collaborations for cross-disciplinary integrations. The main objective of the KLCDD is to explore and develop new ideas, new approaches and new technologies for making the coastal environments more resilient to the impacts of natural hazards and human induced threats.

       The research activities in the KLCDP are mainly related to coastal disaster and defence, including the mechanisms of generation and development, prediction methods and warning systems, reduction and protection technologies, and evaluation and management of coastal disaster. The laboratory has particular interests in the areas of sea level rise and its impact, formation and propagation of storm surge and tsunami, saltwater intrusion in estuary, warning technology of storm surge, coastal dynamics of disaster process and its induced sediment transport, prediction of change of environmental factors in coast and estuary, design criteria of protection engineering, innovative technologies for protection engineering, damage assessment and recovery measures of protection engineering, the impact evaluation of coastal disaster on ecological environment and social economy and countermeasures. 

       The KLCDP has more than 40 members of which 8 are Professors and 12 are Associate Professors. Three laboratory halls with a total area more than 12000 m2 are equipped with high-tech devices and facilities, including wind-wave-current flume, 3D wave basins, sedimentation circle flume, open multi-pump tidal control system, PIV system, ADV system, OBS system and so on. Five field observatories are located along Jiangsu Coast for monitoring the coastal dynamics and disasters, in which surface water elevation, current speed and direction, wave height and period, wind motion, water quality and the others are recorded. A set of high-performance computing cluster system of Hohai University, known as HHU-GRID, is a data-intensive computing platform especially designed for modeling real-time disaster risk in coastal regions (Figure 1). 

       There are many researches carried or supported by the KLCDP, by the end of 2017, the researches include: Study on the characteristics and mechanism of the Indian-Pacific Ocean the sea-level variation; Coastal disaster evaluation and regionalization of Shanghai; The propagation and wave run-up of isolated waves across coral reefs; High-resolution prediction system of tide-wave climatology and the stability of seawalls in the bay area of Guadong, Hong Kong and Macao”; ”Study on the origin and early-warning system of water pollution accidents in Pearl River estuary”.
