Abstract

This study discusses the importance of phreatic surface in the stability of slopes. It describes the development of phreatic layer based on Dupuit and Forcheimmer assumptions in the slope. To understand the water flow behavior through slopes, design of prototype was prepared and later the set-up was fabricated in the laboratory. The set-up includes simulated conventional dump made up of soil type material. The design of experimental set-up resembles the actual scenarios of overburden dumps constructed over the bases having inclination varying from 0 to 5°. The phreatic surfaces obtained in physical models are further compared with numerical models prepared using SEEP/W software.
