Abstract
The Prespa-Ohrid lake system is shared between Greece, Republic of Macedonia
(Former Yugoslav Republic) and Albania. In the recent years a water decrease in
the Prespa Lake has triggered a number of studies on this very complex and
important water system. As part of an international research project in which
institutions from the UK, Greece, R. Macedonia and Albania took part, which
was supported by the NATO Science for Peace (SfP) programme, the problem of
water loss in the Prespa Lake has been investigated. Previous studies have
established that the water from the Prespa Lake flows into the Ohrid Lake
through the Galichica Mountain. As part of the study the flow through the
mountain has been analysed using a free surface flow model. The model has
been solved using a multi-domain boundary element method approach.
Keywords: Prespa-Ohrid lake system, free surface groundwater flow, Galichica
aquifer.
1 Introduction
Three lakes: Ohrid, Big Prespa and Small Prespa are on the borders between
Albania, Republic of Macedonia and Greece, see Figure 1. A hypothesis
published at the beginning of the 20th century [1] predicted that the water from
the Prespa Lake drains into Ohrid Lake through the Galichica and Dry
mountains, which separate the two lakes. Investigations involving the use of
natural isotopes
