The Problem Of Gypsum Soils is considered as one of the main problems that affect large agricultural areas in Syria. In particular, this has been observed in the Euphrates valley since the Great dam was built in the seventies.

As Gypsum dissolves in the water, pore spaces and cavities are formed below coated irrigation channels. This usually results in the collapse of coatings and causes great damage to the channels.

Keywords: asphalt concrete, porous concrete, drainage.
