  4. Content • Introduction • Parameters and indicators • Use of indicators • Outline • Work plan 10. Indicators of success

  5. 1. Introduction - Compiling information on indicators of success from case study sites - Research advanced monitoring methods to assess the success of a scheme. Compare, combine and enhance monitoring methods to be specific to urban rivers - Select parameters that demonstrate key components and issues related to rehabilitation schemes - Convert parameters into indicators - Demonstrate indicators related to the improvement of - water quality - ecological value and biodiversity - amenity value and aesthetics - social and economic well-being 10. Indicators of success – What it’s about

  6. 2. Parameters and indicators Parameter: A property that is measured or observed (primary data) Indicator: A parameter or value derived from a parameter; which points to, provides information about, or describes the state of a phenomenon, environment, or area with a significance extending beyond that directly associated with a parameter value - An indicator is a quantitative measure of an impact without stating whether the change itself is positive or negative - An indicator must : reflect changes be reliable and reproducible - It should be linked to policy goals Index: A set of aggregated or weighted parameters or indicators 10. Indicators of success – Definitions

  7. 2. Parameters and indicators 10. Indicators of success - Hierarchy

  8. 3. Use of indicators • To communicate problems of a site, enabling the general public and its decision makers to realise the gravity of existing conditions • To set goals, objectives and thresholds against which conditions can be measured • To communicate results of an urban river rehabilitation effort 10. Indicators of success – Use of indicators

  9. 4. Outline • Water quality - physical – chemical Sources: - Water Framework Directive - Existing monitoring programs - Additional research - Partner experience Exp.: - Heavy metals, hazardous substances - nutrients 10. Indicators of success – Water quality

  10. 4. Outline Hydrology and hydro-morphology - discharge - connectivity - Other specific issues Sources: - Water Framework Directive - Existing monitoring programs - Additional research Exp.: - Bankfull discharge - Stream structure (D) - Macroscopic instream habitat registration (D) 10. Indicators of success – Hydrology and hydro-morphology

  11. 4. Outline • Ecological value and biodiversity - Aquatic and riparian flora - Aquatic and reparian fauna - Other specific issues Sources: - Water Framework Directive - Existing monitoring programs - Additional research Exp.: - Saprobic Index 10. Indicators of success – Ecology

  12. 4. Outline • amenity value and aesthetics • Public perception of rivers • Sensual experiences • Public acceptance • Recreational value Sources: - Literature (Kevin Lynch, etc) - URBEM Exp.: - High visitor rates - Perceived amenity 10. Indicators of success – Amenity value and Aesthetics

  13. 4. Outline Social and economical - Public safety - Incentive for economic investment - Stakeholder networks - Advocacy and stewardship Sources: - Literature - URBEM (Case studies) - Crime rate Exp.: - Adjacent property values - Number of stewardship activities 10. Indicators of success – Social and Economical

  14. 5. Suggested work plan example 10. Indicators of success – Work Plan
