1986年1月21日至2月6日,由天津市水利局组织的五人考察小组(其中海委一人)赴荷兰就农田水利与土壤盐碱地综合治理问题进行了考察。考察期间,访问了德尔夫特水工实验室。该实验室是世界上最大的水力学研究机构之一。他们以雄厚的技术力量、广阔的研究范围而闻名于世。代表着国际水力学研究的新水平。在水文水资源系统分析及环境影响评价方面,其研究范围主要包括:地下水和地表水的定量和定性管理;大规模水资源工程的规划与管理;水利工程的环境影响与评价;饮用水系统分析;流域开发与管理;区城水资源开发。 January 21, 1986 to February 6, organized by the Tianjin Water Conservancy five investigation team (including IOC one person) went to the Netherlands on farmland water conservancy and comprehensive management of soil salinity were inspected. During the visit, visited Delft Hydraulic Laboratory. The laboratory is one of the largest hydraulics research institutes in the world. They are famous for their strong technical strength and extensive research scope. Represents a new level of international hydraulics research. In terms of systematic analysis of hydrological and water resources and environmental impact assessment, the scope of its research mainly includes: quantitative and qualitative management of groundwater and surface water; planning and management of large-scale water resources projects; environmental impact and evaluation of water conservancy projects; analysis of drinking water systems ; Basin development and management; development of district water resources.
