SYNOPSIS 
 
Changes in the global climate, due to an increase in global temperature, have resulted in unusually high rainfalls in some parts of the world. In the last few months, Malaysia experienced unusually high rainfalls. These heavy rainfalls have affected the stability of many slopes.
 
This workshop focuses on the research outcomes on the mechanism of rainfall infiltration into residual soil slopes and their effects on stability in the local context. Unsaturated soil mechanics and properties are used in assessing stability and the measurement results will be presented. Several preventive measures for rainfall-induced slope failures are investigated and their results will also be illustrated. 
 

BIODATAOF SPEAKER
 
Ir. Professor Harianto Rahardjo Bandung I.T., MSc PhD (Sask.), PEng ( Sask.), PEng (S'pore)
 
Professor Harianto has conducted extensive research on unsaturated soil mechanics to solve geotechnical problems associated with tropical residual soils, swelling and collapsible soils. His current research focus is on rainfall-induced landslides, one of the major environmental problems affecting many countries in tropical regions. This research activity has led to the development of unsaturated tropical soil engineering laboratory in Nanyang Technological University (NTU). He is also the co-author of the first textbook on unsaturated soils “Soil Mechanics for Unsaturated Soils”, by Fredlund, D.G.and Rahardjo, H. (1993), John Wiley & Sons, Inc., New York, which contained 517 pages and over 200 technical publications.
 
Prof. Harianto has also presented his research works in many keynote / invited lectures and short courses in various countries. He is Core Member of the TC6 Committee of International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) on Unsaturated Soils and Member of the Asian Technical Committee on Geotechnical Natural Hazards (ATC3). He has served as a consultant on various projects to several engineering firms and government institutions in Singapore, Malaysia, Hong Kong, China, Canada and Indonesia.
