In 2001, a scientific project was launched to collect information that could provide better knowledge of the whole structure of the city.
With the help of a geophysical survey, precious insights into structures buried under mud hills became possible. Cross checking of the new data with previous existing archaeological data enabled to date and to interpret all the structures.
Unfortunately, the site is under potential threat of illegal digging and associated looting. To better monitor the site a new project has been initiated with the German Space Agency (DLR) using recent satellite imagery.
