DROUGHT ACTION PLAN IN THE SEGURA RIVER BASIN
ADOPTION OF drought INDICATORS (1/2)
• A system of representative status indicators is defined with respect to the evolution of the offer of resources and the demands to fulfil in each operation sub-systems (the Taibilla Canal Consortium System, the River Basin System and the Tajo-Segura Transfer System).
• These indicators are composed of various variables that include both reservoir storages and natural flows in the river basin.
• The indicators are adopted definitively after calibration and validation in relation to real situations in order to verify their adequacy.

DROUGHT ACTION PLAN IN THE SEGURA RIVER BASIN
The Special Action Plan for Drought Situations was approved on 21 March 2007 (BOE 23/03/07), the value of the index related to June 2007 was calculated according to the methodology described in this Plan.

• After the approval of the Drought Decree, a Drought Monitoring Permanent Commission is created, which includes the principal officers in charge of water resource management, the users and the principal stakeholders of the river basin.
• This Commission will be advised by the Drought Technical Office formed by a multidisciplinary technical team active in the scope of the river basin authority.
• A Public Participation Process will be undertaken, both for the adoption and approval procedure of the Plan and for the adoption the most significant measures.

• Within the Segura River Basin, there are 18 municipalities of more than 20,000 inhabitants (15 are supplied by the Taibilla Canal Consortium + Hellín, Yecla, Jumilla) the emergency plans of which were presented to the Segura River Basin Authority.
• The Special Drought Plan contains the definition of the basic elements for co-ordination and homogenisation of these emergency plans.
