Construction dewatering in reclaimed land in Hong Kong — a review of best practices

Abstract

A sound understanding of groundwater engineering principles is a prerequisite for effective construction dewatering and the associated pumping tests. This paper makes practical recommendations to improve dewatering designs in reclaimed land in Hong Kong and the interpretation of groundwater monitoring data. The paper first introduces the reader to the hydrogeology of Hong Kong and its implications on dewatering. It then draws upon experiences in Hong Kong, reviewing and recommending best practices in groundwater monitoring, and the design of extraction and recharge wells.
