Association of Drainage Authorities: Administrative Boundaries - Internal Drainage Districts in England

PLEASE NOTE: This data has been published by the Environment Agency on behalf of the Association of Drainage Authorities. © Association of Drainage Authorities copyright and/or database right 2020. All rights reserved.

Under the Land Drainage Act 1991, internal drainage districts are areas defined as deriving benefit or avoiding danger as a result of drainage operations. Each internal drainage board (IDB) is a local independent public body that manages water levels in the corresponding internal drainage district.
IDBs undertake works to reducing flood risk to people and property, and manage water levels for agricultural needs and for the protection and enhancement of the environment within their district. IDBs are defined as a type of Risk Management Authority under the Flood & Water Management Act 2010.
Whilst indicative, the data is the most comprehensive and consistent national dataset of internal drainage district boundaries in England.

根据1991年土地排水法，内部排水区是指因排水作业而受益或避免危险的地域。每个内部排水委员会（IDB）是相应内部排水区的地方独立公共机构，负责管理该区域的水位。
IDBs承担减少洪水风险、保护及改善其辖区内的农业用水需求和环境保护的工作。根据2010年洪水与水资源管理法，IDBs被定义为一种风险管理机构。
尽管具有指导性，但该数据是英格兰内部排水区边界最全面、最一致的国家数据集。
