Title: Implementation of the Water Framework Directive Role of geotechnical activities

Implementation of the Water Framework
DirectiveRole of geotechnical activities

3rd Network Meeting GeoTechNet London, 4-5
December, 2003

WFD General planning process
All waters in good ecological status

IMPRESS Report
  • Pressure screening
  • Pressure quantification
  • Impact assessment

This all need to be completed by the end of 2004
4
2nd Report River Basin Management Plan
  • to be completed by the end of 2009
  • consists of (i.a.)
  • summary of significant pressures and impacts
  • summary of economic analysis
  • programme of measures

5
What happens between 2004 and 2009?
  • inter-calibration (2006) and monitoring (2006)
  • classification, setting the objectives
  • better understanding of the impacts of different
    pressures
  • how much pressures need to be reduced to achieve
    the objectives
  • assess the optimal (cost-effective) set of
    abatement measures

6
Classification
EQR close to 1
High status or reference conditions (RC)
Good status
Moderate status
Poor status
Bad status
EQR close to 0
7
Classification
  • We have to divide our water bodies into good
    and bad
  • Nature does not give us any help
  • There are no jumps in distributions

IMPRESS-Analysis
  • Identify human activities that put the
    Directives environmental objectives at risk
  • ? Pressures according to Annex II, WFD

14
Pressures, impacts and risk analysis
  • Identifying and quantifying significant
    pressures
  • all significant pressures
  • loadings, hydromorphological pressures,
    management
  • Identfying and quantifying significant impats
  • use screening criteria and existing
    classification schemes
  • identify significant impacts
  • tiered approach
  • Risk analysis
  • analyse which water bodies are at risk not to
    meet the ecological objectives
  • What is significant?
  • Significant pressure is a pressure causing an
    impact with a risk to failure to meet the
    objective

15
Key elements of the analysis
Conditions required to achieve the objectives
Annex III economic analysis (WATECO)
Identify potential relevant effects of pressures
(i.e. the hazard)
Characteristics of water bodies that determine
their susceptibility
Assess susceptibility to the effects of pressures
Magnitude of pressures
Identify likely effects of pressures
Decide on the likelihood of failing to achieve
the Directives environmental objectives
Environmental conditions required to achieve
objectives
16
Reduce uncertainties -Tiered approach
17
Where do we need IMPRESS?
Identification of potential reference sites
(Annex II)
Design of programmes of measures (Article 11)
Make objectives operational and Identify water
bodies for which alternative objectives may be
appropriate (Article 4)
Identification of potential inter-calibration
sites (Annex V)
Information for use in water body identification
and refinement (Annex II)
Design of monitoring programmes (Article 8)
Information for producing an interim overview of
the significant water management issues (Article
14)
Information for use in the economic analysis of
water use (Article 5)
18
Role of geotechnics
Geotechnet WP5
  • Environmental impact may arise as a result from
    geotechnical working methods such as vibration,
    compaction, grouting, injection, abstraction of
    water, land sealing, damming, drainage and the
    use of residues as alternative construction
    materials.

19
Role of geotechnics- Pressures
  • Loading
  • Erosion
  • Nutrients
  • Heavy metals
  • Organic pollutants
  • Hydromorphological pressures
  • water abstraction
  • damming
  • other river constructions (e.g. dikes)

20
Role of geotechnics
  • Programme of measures
  • minimize pressures
  • Can geotechnical operations be used as remedial
    measures?
  • Dredging?
  • Drainage?
  • ?

21
Conclusions- Problems
  • Stakeholders have different views and
    expectations
  • how to fit together natural sciences and
    socio-economic aspects
  • time schedules
  • resources

22
Conclusions - Geotechnics
  • Geotechnical operations may cause and are causing
    pressures and impacts
  • Geotechnics may also serve as remedial measures
    to improve the ecological quality of our water
    bodies
