Abstract.
The Kafrein dam, 480 m long and 30 m high, is located on the Wadi Kafrein, a few kilometres from the active Jordan Valley fault. The Jordan Valley Authority proposed raising the crest of the existing dam by approximately 7 m and extending the length of the embankment to 554 m, in order to increase its storage capacity by 6 million m3 to a total of 8.5 million m3. The paper discusses the likelihood that existing seepage problems will be exacerbated when the dam is raised and proposes some remedial actions to increase the safety of the dam and minimise both the amount of seepage and any adverse effects.
Résumé.
Le barrage en terre de Kafrein, de 480 de longueur et 30 m de hauteur, est situé sur l’oued Kafrein, à quelques kilomètres de la faille active de la vallée du Jourdain. La Jordan Valley Authority a proposé de surélever la crête du barrage d’environ 7 m et de rallonger le remblai de 554 m, afin d’augmenter la capacité de stockage de 6 à 8,5 millions de m3. L’article examine la possibilité d’une aggravation des fuites existantes et propose des mesures correctives pour améliorer la sûreté du barrage, diminuer les fuites et atténuer tout effet négatif.
