سرعة التحلل الكارستي و آثارها على المنشآت الهندسية في مدينة تلعفر

Abstract EN

The study investigated the speed of the karstic dissolution in the city of Tal Afar.

The geological factor in the gypsum and Limestone rock formation as well as the climatic conditions are the main determinants of the speed of karstic dissolution.

Other factors such as geomorphology, soil and natural vegetation.

The results of the study showed that the value of the decomposition in gypsum rocks reached 16.5 mm / year, while its value in Limestone rocks reached 17.4 / 1000 years.

This variation is due to the availability of the most suitable natural factors for gypsum rocks, For its Limestone counterpart.

The study showed the negative effects of the phenomenon of karstic dissolution on the various engineering facilities and infrastructure, which requires finding solutions.
