Twenty years of protection of rivers on the coast of the Region of Murcia (1994-2014 ). Evaluation of the efficiency of the measures of Planning

Abstract

A significant increase in episodes of flooding on the coast of Murcia occurred in last decades, questioning the role of preventive strategies on planning. In this paper is evaluated the efficiency of river channel protection actions included in the Guidelines and Planning of Región de Murcia Coast. The cadastral information and the hydrological modeling of 10, 50, 100 and 500 years of return period have been used to study the evolution of vulnerability. The results shows that exposure to risk has continued to increase even after the adoption of these guidelines, becoming a key factor in the increase of economic losses associated with flooding.
