Mechanism of sloping capillary barriers under high rainfall conditions

Abstract

This thesis consists of 2 sections. In this research, the mechanism of sloping capillary barriers under high rainfall conditions was assessed through both laboratory experiments and numerical analyses. An infiltration box apparatus [2.45 m (L) x 2.0 m (H) x 0.4 m (W)] was designed and constructed in laboratory This facility was equipped with comprehensive instrumentation and data acquisition systems, such as pressure transducer-tensiometer system; time domain reflectometry (TDR); magnetic flowmeter and electronic weight balances. Rainfalls of different intensities and durations can be simulated through a rainfall simulator located at the top of the infiltration box.
