為各種自然和人為的排放進行環境影響評估是必須的。這些排放包括深海熱岩液、淨化海港計劃(HATS) 處理後的生活污水、核電站排放的受污染冷卻水、或海水化淡廠排放的高濃度鹽水、以及工廠意外洩漏的有毒化學品。

本講座將探討香港水環境影響評估的挑戰，並解釋污染物如何從源頭運送至各個敏感受體。講者將介紹「WATERMAN環境影響評估系統」的主要元素，包括可靠的三維水動力及水質模型、先進的可視化系統及網絡圖像科技，並展示該系統在各種環境問題上的應用(例如污水消毒處理的實時控制)。本講座將以粵語及普通話進行，並備有英語即時傳譯。

It is necessary to assess the environmental impact of natural and man-made discharges such as hydrothermal vents in the deep ocean floor, treated sewage effluents from the Harbour Area Treatment Scheme (HATS), contaminated cooling water discharges from nuclear power stations, brine discharges from desalination plants, or accidental toxic spills from factories.

This lecture will address the challenges of the EIA practices for the water environment in Hong Kong. The processes governing the fate and transport of the pollutants from the sources to the various sensitive receivers will be explained. The major components in Project Waterman's EIA system will be introduced. The development of robust modelling, advanced visualization and Internet-based graphics technologies will be illustrated together with practical application examples including the real-time control of disinfection dosage. The lecture will be conducted in Cantonese and Putonghua with simultaneous English translation.

香港市民每天食用超過三百噸海魚，是全球平均量的四倍，位居亞洲城市前五名。明年本港將全面實施禁止拖網捕魚，面對市民對優質海魚的大量需求，本地海魚養殖業的可持續發展將變得尤其重要。

「WATERMAN系統」為香港海魚養殖業的管理作出兩方面的貢獻。在長遠發展方面，「WATERMAN系統」可計算出各漁區的環境承載力及建議養魚量，以實現海洋資源的可持續利用，並避免對周圍環境造成不良影響。在短期水質預報方面，WATERMAN的紅潮預警系統能提供實時紅潮風險預測及減災建議，以減少對養魚業造成的損害（比如1998年的災難性大紅潮）。「WATERMAN系統」是全球首個同類型預警系統。

本講座將介紹「WATERMAN」漁業管理和紅潮預警系統的基本原理，及其對本港海魚養殖業的裨益。本講座將以粵語進行，並備有英語即時傳譯。

Hong Kong is one of the top five fish consuming cities in Asia. Every day, we consume over 300 tonnes marine fish, which is four times the world’s average. In view of the banning of local fish trawling and the demand for high quality seafood, the role played by local marine fish farming becomes particularly important.

The WATERMAN system provides two advisories for sustainable development of Hong Kong mariculture. The long term advisory on optimal fish stocking size can ensure sustainable use of the marine resources without causing adverse impact to the surrounding environment. The short term red tide early warning and mitigation advisory can minimize fish kill due to red tide disasters (such as the 1998 devastating red tide). Worldwide, this is the first early warning system of its kind.

This lecture will introduce the basic principles of the WATERMAN fisheries management and red tide early warning system, and how it benefits Hong Kong fisheries and environmental management. It will be conducted in Cantonese with simultaneous English translation.
