3rd Network Meeting GeoTechNet London, 4-5
December, 2003
2WFD General planning process
All waters in good ecological status
3IMPRESS Report
- Pressure screening
- Pressure quantification
- Impact assessment
This all need to be completed by the end of 2004
42nd 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
5What 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
6Classification
EQR close to 1
High status or reference conditions (RC)
Good status
Moderate status
Poor status
Bad status
EQR close to 0
7Classification
- We have to divide our water bodies into good
and bad - Nature does not give us any help
- There are no jumps in distributions

13IMPRESS-Analysis
- Identify human activities that put the
Directives environmental objectives at risk - ? Pressures according to Annex II, WFD
14Pressures, 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
15Key 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
16Reduce uncertainties -Tiered approach
17Where 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)
18Role 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.
19Role of geotechnics- Pressures
- Loading
- Erosion
- Nutrients
- Heavy metals
- Organic pollutants
- Hydromorphological pressures
- water abstraction
- damming
- other river constructions (e.g. dikes)
20Role of geotechnics
- Programme of measures
- minimize pressures
- Can geotechnical operations be used as remedial
measures? - Dredging?
- Drainage?
- ?
21Conclusions- Problems
- Stakeholders have different views and
expectations - how to fit together natural sciences and
socio-economic aspects - time schedules
- resources
22Conclusions - 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
