Abstract
In 1979-81 a stretch of 10 miles of Chashma Right Bank Canal was excavated and double layer brick tile lining was done. The lining was cured by flooding it with water through open drains made on either berm of lining. A couple of months after the completion of the lining, horizontal cracks were observed on either bank. Field density, moisture measurements, Soil classification and double Oedometer tests were performed. In situ water pending tests were also conducted. The observations and the test results revealed that the cracks were the consequence of collapse of silty low density soil due to saturation. The areas having different degree of collapse potential were delineated. It was decided to saturate and precollapse the areas having severe collapse potential. The areas of moderate and low collapse potential were treated by over excavating and compacting the banks and bed of the canal. This proved quite efficient and successful.

Collapsible Soils Chashma Right Bank Canal
In 1979-81 a stretch of 10 miles of Chashma Right Bank Canal was excavated and double layer brick tile lining was done. The lining was cured by flooding it with water through open drains made on either berm of lining. A couple of months after the completion of the lining, horizontal cracks were observed on either bank. Field density, moisture measurements, Soil classification and double Oedometer tests were performed. In situ water pending tests were also conducted. The observations and the test results revealed that the cracks were the consequence of collapse of silty low density soil due to saturation. The areas having different degree of collapse potential were delineated. It was decided to saturate and precollapse the areas having severe collapse potential. The areas of moderate and low collapse potential were treated by over excavating and compacting the banks and bed of the canal. This proved quite efficient and successful.
