Criteria (based on issues qs and ws)Infrastructural Manageme

ntLegislative Awareness

Increase of surface water and ground water pollution

Waste water treatment plants

Compliance monitoring plans

Enforce standards

Capacity building for local water authorities

Increase in irrigation demands

Newchannels/dams

Decision from the Council of Ministries

Increase of domestic demand (increase of urbanization)

Awareness Campaigns

Incorrect exploitation of the river in Tourism/ violations

Monitoring and control

Improve permitting system

Awareness campaigns

Losses to the sea (winter)

Newchannels/dams

Development of the Agricultural sector

Training on new techniques for irrigation

Intro. The river basin Stakeholders WP05 Obj/ConstObj/ConstLanduse change Conc. WRM Instruments

•Environmental Level flow in the river in some portions (especially at the coast)•Supply meeting consumption demand

•CONSTRAINTS

•OBJECTIVES

•Increase water demand efficiency•Better exploitation of the River (balanced exploitation)•Control sources of pollution•Decrease losses to the sea

Intro. The river basin Stakeholders WP05 Obj/ConstObj/ConstLanduse change Conc. WRM Instruments

•Irrigation canal (8.05m3/sec agricultural use and 0.64 m3/sec domestic) cost of 132Million Euros•2 Dams (128 Millions m3)•Waste water treatment plant(s)•Hydroelectrical plant(s)•Hill lakes

•Infrastructure

•Update legislation/improve enforcement•Decrease violations on River

•Legal

•Management •Water pricing•Improvement of the canalization (decrease of losses)

•Awareness campaigns

•Irrigation technologies (surface irrigation to drip or sprinkle)•Alternative crops (less water consuming)

INSTRUMENTS

Intro. The river basin Stakeholders WP05 Obj/ConstLanduse change Conc. WRM InstrumentsInstruments

PROBLEMS

•RRM model (daily data for control points on subcatchment, data cannot be calibrated to a control station)• Water Quality (Stream cannot be used since there were no levels of BOD detected during sampling in the River; potential campaign in summer(?))

FUTURE WORKS

•Finalize Baseline scenario (data, economic information, etc.)•Input to WP04 (Instruments and water technologies, cost of infrastructure on the River •Optimization runs•Second workshop to quantify constraints, validate scenarios, in August 2006 after the progress report
