SHUSHTAR, a town in the province of Khuzistan, Persia, about 32° N. and 49° E., in the angle formed by the bifurcation of the Karun River into the Ab i Gargar and Ab i Shatait, some 40 m. below the point where the Karun debouches into the plains from the Bakhtiari mountains. The town covers a larger area than its estimated population of 20,000 warrants, being in large part in a ruinous and deserted condition; it has indeed been described as one of the most tumble-down places in all Persia. Many of the houses, of stone and brick, have cellars, called shewadan, in which the inhabitants shelter in the excessive heat of summer, which on occasion reaches 128° F. The sanitary conditions are very bad. The bazaar is a poor one and the few permanent shops are to be found in the street leading through the centre of the town to the Pul i Bulaiti (bridge). Even the mosques are devoid of special architectural features except perhaps the oldest one built under the Abbasids. On the other hand, the citadel, or Qal'ah Salasib, is a most imposing though ruinous mass, crowning the cliff, covering an area 35o by iso yd., and described by Sykes as "the finest fort he had ever seen in Persia." The town has three exits : (a) west ward over the bridge to Dizful, now interrupted owing to the bridge being broken down in the middle, its place being taken by a ferry; (b) southward by the Pul i Lashkar road to the Miy anab (the name of the fertile tract between the Gargar and Shatait branches) ; and (c) over the great dam to the suburb of Bulaiti. Water Works.—Shushtar is most famed for the great works constructed in ancient times for the disposal of the voluminous water of the Karun river. These comprise (a) the Ab i Gargar Canal (the Masruqan of the middle ages). (b) The great barrage called the Band i Qaisar which is thrown across the Ab i Shatait (the principal arm of the river) west of the town. It is about yd. long and supports a bridge, the Pul i Dizful (previously re ferred to). (c) The canal called Minau, which takes off above the barrage by a tunnel cut out of the rock on the western side of the town below the citadel, the purpose of which was to irrigate the Miyanab. Tradition says that the Minau Canal was built by Dara the Great and that it was Ardashir I. (the Sasanid) who began to construct the barrage after the canal mouth had dried up. The barrage was only completed under Shapur II. by the Roman prisoners with Valerian II. The Ab i Gargar was first dug simply to divert the volume of the water of the main river; the Band i Qaisar was then constructed, the bed of the river above the barrage was paved with huge stone slabs bound with iron, to pre vent further erosion. This paving was called Sliadurwan, a term
also applied to the barrage itself. Ultimately, a new barrage is said to have been built across the Gargar.
