Abstract

The overall objective of this study is to determine the effect on hydraulic conductivity of laboratory-compacted soil when exposed to recurring wet-dry cycles. This is comparable to naturally-occurring climatic events and periodic pumping of lagoons. The wet-dry cycling was performed in laboratory simulations at typical outdoor summer temperatures, which include an average temperature of 32°C and an extreme temperature of 62°C. Chapter Two summarizes existing literature that addresses clay liner hydraulic conductivity and desiccation characteristics. Chapter Three outlines the soil properties of the test specimens and the development of test procedures. A summary of the preliminary testing appears in Chapter Four. Descriptions of the tests performed and their results appear in Chapters Five and Six, with conclusions and recommendations outlined in Chapter Seven.
