The Eastern and Wes tern Harbours are clearly visible in the centre of the image, as well as the dark surface of Lake Mariout immediately to the south. With respect to the pollution of coastal waters, a plume of suspended matter from the Mex pump station is clearly visible arcing eastward from El Mex Bay towards the Qait Bey area. Also worthy of note is the impact of the El Tabya pump station on the waters of Abu Qir Bay on the right side of the image (see the article in this volume by Y. Halim and F. Abou Shouk).

One reservoir of such treasures - the coastal sea - has been increasingly explored in recent years. The DIRK G. TROOST submarine nature of this long-inaccessible Chief, UNESCO-CSI reservoir, distinguishing it from the more easily surveyed and exploitable terrestrial heritage, presents unique problems necessitating special approaches. This need is all the more urgent in view of the impacts, on the coasts, of advanced development technology and in particular, the advent and easy availability of modem diving equipment. The coastal waters of the Mediterranean constitute some of the planet's richest areas in terms of abundance in archaeological relics. In recent years, the city of Alexandria, Egypt, has captured public attention owing to the underwater discoveries of what are believed to be the remains of the Alexandria lighthouse and Cleopatra's palace. To further explore and develop techniques and strategies in pursuit of integrated approaches to coastal management, the University of Alexandria, the Supreme Council of Antiquities and UNESCO co-sponsored an intersectoral workshop in Alexandria (April l 997). The present volume contains the edited papers from this workshop. It conveys the information, views and analyses of well- Table of Contents Foreword 11 Introduction - Alexandria in an evolving context 13 ALEXANDRIA IN EARLY TIMES: HISTORICAL PERSPECTIVES The greatest emporium in the inhabited world (Mostafa El-Abbadi) 17 The two ports of Alexandria: plans and maps from the 14th century to the time of Mohamed Ali (Harry E.
