Title: ASSESSMENT OF WATER SYSTEMS VULNERABILITY TO DROUGHT

Author: G. Tsakiris, H. Vangelis and D. Tigkas

Year: 2009

Publisher: European Water Resources Association (EWRA)

Description:

Water shortage may be caused by intense drought events and/or mismanagement of available water resources. To face water shortage caused by drought, proactive measures should be taken in a timely and well organised way. The paper gives guidelines for the estimation of water shortage risk in the strategic and operational preparedness plans of a complex water system. It is concluded that for the operational preparedness plan important tools are required: a) a simplified drought monitoring system, b) a forecasting tool for assessing annual drought severity, c) a deterministic mechanism for estimating the consequences, and d) a prioritised water allocation methodology based on annualised risk.
