Guidelines for Coastal Erosion Management at National, Regional, and Local Levels

This resource provides guidelines for implementing effective coastal erosion management, addressing both physical and policy aspects. It offers a systematic approach to identify problems, make responsible choices, set objectives, and evaluate interventions. The guide also includes information on data collection, modeling, and decision-making processes. Available in English.

  7. Guidelinesfor implementation of coastal erosion management at national, regional and local levels a systematic approach : Frame of Reference

  8. a systematic approach : question loop

  9. It is just the coast line that worries me …. Lovely ocean, I must say .. a systematic approach : question loop Make problems, choices and responsibilities explicit !

  10. a systematic approach : question loop

  11. WHY is it a problem? • functions ? • regulations ? • policy goals ? • physical causes ? • WHO is concerned ? • interests ? • power ? • responsibility ? • finances ? • WHAT should be achieved ? • Set objectives • WHO is responsible ? • Specify • examples: • preserve dune strength • maintain beach configuration • reduce coastal erosion • prevent damage to infrastructure a systematic approach : question loop What is the problem ?

  12. barrier width • dune heigth • beach width • shore line position • shoreface volume • coastal cell volume • etc. • WHAT measurable indicator(s) describe the objectives? • What time- and space scales are involved ? • What data are available ? • What monitoring is needed ? • What modelling is applicable ? • WHO is responsible ? • Decision making process How big is it ? a systematic approach : question loop What is the problem ?

  13. favourable sediment status • WHERE and WHEN do the indicator(s) reach a critical value ? • Benchmarking ! • What data are available ? • What monitoring is needed ? • What modelling is applicable ? • WHO is responsible ? • definition of desired state How big is it ? Action needed ; yes / no? a systematic approach : question loop What is the problem ?

  14. strategic sediment reservoir • HOW to restore or maintain the desired state of the indicator(s) ? • Choice of intervention method • WHO is responsible ? • organization of erosion management • finances How big is it ? What intervention is applicable ? Action needed ; yes / no? a systematic approach : question loop What is the problem ?

  15. WHAT is achieved by the intervention method ? • evaluation of effects • WHO is responsible ? • decision making process Does it work out ? What intervention is applicable ? Action needed ; yes / no? a systematic approach : question loop What is the problem ? How big is it ?

  16. Does it work out ? What intervention is applicable ? Action needed ; yes / no? What is the problem ? How big is it ?
