5 Towards Developing Guidelines

considered for a particular activity or project. The risk may be judged as acceptable or
unacceptable according to how frequently an event happens and how much "damage"
the event does. Risk assessment provides a framework within which the potential benefits and hazards of a project or course of action can be determined using either a
quantitative or a qualitative approach.
There are many different aspects of risk which should be considered at various stages
in the barrier/barrage design process, including environmental, economic, structural
and flood risks. General information and definitions concerning risk analysis and management are given in the guidelines. However, in brief, the guidelines consider in detail
water-related risks including: hydrometeorlogical risk, construction risk and operational risk.

Environmental Policy
Environmental policy must take account of the issues outlined in the previous section.
This section examines the environmental policy framework under which the barrages
must be planned, constructed, operated, modified and maintained. Although much of
these are UK-based, they are usually derived from aims of the EU directives and/or the
Rio Summit striving for sustain ability and biodiversity.
5.5.1
Environmental Assessment and Environmental Statement
Environmental Assessment was formally introduced into the UK by the Town and Country Planning (Assessment of Environmental Effects) Regulations 1988 (SI 1988 No. 1199)
which implemented much of the European Community Directive on the assessment of
the environmental effects of certain public and private projects on the environment
(8S/337/EEC). Environmental Assessment aims to ensure that any significant effects of
new development on the environment are assessed before they take place. The regulations classify barrages as Schedule 2 developments which may require a formal Environmental Statement (ES) if they are to have "significant" effects.
Prior to a full Environmental Assessment, the Environment Agency would expect to
see a scoping document based on "Further Guidance on the Environmental Assessment of Project" to ensure that an Environmental Assessment will cover all of the issues concerned. The Environment Agency would expect to see an Environmental Assessment undertaken for all barrage schemes. The assessment would address the effect
that the barrage construction will have on the environment. In order to fulfil its basic
aim, environmental assessment should be undertaken in parallel with project design.
It will normally examine the following issues under the following broad headings:
• Hydrology
• Morphology
• Flooding
• Groundwater
• Water quality
• Fisheries
