Ayaz Kala I is a fortress dating back to end of the 4th or beginning of the 3rd cent. BC. In this time Khorezm had become independent from Persia. Ayaz Kala I was part of a chain of fortresses protecting the agricultural settlements from attacks invaders from the north (Syrdarya).
From historical reports that such a natural shift was in progress during the 10th
century, when Kaṯ was at the zenith of its prestige.
According to a Chorasmian tradition related by Abu Rayḥān
Al-Biruni's Āṯār, one
of the Afrighid Kings, whose reign began in AD 616 in the era of
Alexander (and the Seleucids) built his castle at Fir on the
outskirts of Kaṯ; this citadel consisted of three concentric forts, in the
middle of which rose the royal palace. Fir’s fortifications were so high that
they would be visible from a distance of fifteen km or more. The citadel Fir
(or Fil) was conquered by the Arabs in AD 712. In terms of size and
splendour the capital of Chorasmia rivalled the other major urban centres of Central
Asia. According to Al Biruni, who eye-witnessed the flooding of his hometown
before his emigration at the age of twenty-five (in 998) to Iran, Fir “was broken and
shattered by the Oxus, and was swept away piece by piece every year, till the
last remains of it had disappeared” in the year 1305 of the Seleucid era (AD 994).
The modern history of Kat has been marked by more flooding and
population shifts but also by name changes. In the 17th century, another wave
of flooding washed out the old canals. As a result, Anusa, the Khan of Khiva
(1663-85), ordered he construction of the Yarmis canal and built a fortress on the left side of the
Oxus to which he transferred the remaining population. Meanwhile, the ruins of
old Kat on the right side of the river became known as Sheikh Abbas Wali, after
a local mausoleum. 
El canal de Karakum (Karakum Canal, Kara Kum Canal, Garagum Canal; (ruso: Каракумский канал), Karakumsky Kanal) en Turkmenistán, es el más extenso canal de irrigación y suministro de agua del mundo. Su construcción comenzó en 1954, y fue concluido en 1988, es navegable a lo largo de toda su extensión de 1,375 km, y transporta 13 km³ de agua anualmente desde el río Amu-Darya a través del desierto de Karakum en Turkmenistán. El canal permitió el desarrollo de la agricultura en grandes extensiones de tierra, especialmente el monocultivo del algodón muy promocionado por la Unión Soviética, y es una fuente de agua muy importante para Ashgabat.
