Abstract
Until very recently, the public water supply in the Algarve region was almost
entirely supported by groundwater wells. However, in the last years of the 20th
Century, the Portuguese government defined a scheme for the public water
supply sector entirely based on surface water from large dams, in order to
guarantee the public water supply. The efforts to abandon groundwater as a
source for public supply started in 1998, after a large investment in new
infrastructures and rehabilitation of some existing ones. However, the practical
implementation of this water supply scheme showed that an integrated resource
management is needed in order to implement a more economical and reliable
solution. The present paper describes the historical background and the evolution
of water use in recent decades until the present time in the Algarve, and a
proposal for restructuring the management of the water supplies based on the
development of a decision support system within an integrated water resources
management scheme.
1 Introduction
The Algarve region (5400 km2) is the southernmost province of Portugal, as
indicated in Figure 1. The region is characterized by a warm Mediterranean
climate. A mean annual precipitation of 653 mm was calculated for the period
1941/42-1973/74 [1]. Unfortunately the precipitation regime is not regular,
