Real Time Georisk Slope Management System (RTGSMS) is a new system developed for real time prediction of slope instability. This system is very useful for urban development near or on hilly terrains. The system has integrated all factors that induced slope stability and georisk probability using Geographical Information System (GIS). Hence, mitigation measures can be predicted, planned and monitored to avoid high risk to public safety and properties. It is a simple and user friendly system that can be used by all level of personal for slope safety check.

Natural soils particularly sands and gravels have little or no tensile resistance. By determining the degree of soil erodibility and the erosiveness of the rain at any location using ‘ROM’ Scale and ‘ROSE’ Index, the most vulnerable location on slopes can be determined. By having a system package incorporating slope monitoring and early warning system using geosynthetic material with the real time forecasting on the rainfall impact to the slope, the usage of the geosynthetics can be intelligently optimized.
The reinforcement application of geosynthetic is used as the reinforcing element to provide tensile resistance for the strengthening of the soils as adopted for slopes or retaining walls. Geosynthetic reinforced soil retaining structures are therefore more economical in saving land space and construction materials. With more structures being constructed, monitoring the behaviour of the engineering structures is becoming increasingly important demandingly during heavy rainfall intensity areas, over soft foundations or when poor soils are used as construction materials.
Monitoring the behaviour of geosynthetic reinforced soil structures by measuring strains in the geosynthetic reinforcement can be practically made simple by the invention of ‘intelligent’ geosynthetic known as geodetect. Using state-of-the-art technology, high strain build-in-sensors were laser incorporated in the optical fibre to detect strains in the geosynthetic reinforcement. The optical fibre is connected to a measuring device that measures changes in wavelength versus real time. Any stresses exerted in the geosynthetic incorporated fibre optic, will cause a wavelength shift in the sensor that can then be related to a corresponding strain. Constant monitoring and management of a structure can be implemented via telemetry for remote data acquisition and early warning system. Once the change in wavelength or strain limit threshold is reached, a warning system will be activated prior to failure of the structure.
