A large landslide closed California Highway 144 in the Sycamore Canyon area of Santa Barbara, California, December 18, 2000. Continuing hillside movement as the repair effort was underway made the project even more challenging for the contractor. Following the installation of the GEOWEB Slope Protection System, Highway 144 was re-opened in Summer 2001.

Case Study - Land Slide Investigation
The landslide occurred on March 30, 2011. The maximum rainfall (53.1 kg/m2) has been seen in this month during a year. There is igneous rock that composed of tuff, andesite, dasite and basalt on the top of metamorphic schist, graphitic schist and serpentine. There are also basalt and limestone blocks. These blocks were split by fault and moved. The landslide body is consisting of schist and completely ripped dacide and andesite blocks. The basement is saturated serpentine which is very weak competent. There is...
Case study - South Pool Creek, Devon
Part of the works to repair an essentials road recently damaged by a landslide required hydroseeding to it`s slopes and to help retain the soil an erosion control blanket was fitted by the client prior to seeding. Additional tackifier was added to the mix to help bind the sprayed on material to the steep slopes until germination and the establishment of the new grasses.Project Size: 1,000m2Location: South Pool, DorsetClient: South Hams CouncilCompletion: March 2011
Needs and vulnerability assessment (NAVA) indicators for specific hazards in the context of Sri ...
Development of a four hazard-specific toolkit (drought, flood, landslide and chronic kidney diseases of unknown aetiology) for needs and vulnerability assessment in the water, sanitation and hygiene (WASH) sector included community consultations with district, divisional and community stakeholders in four selected districts of Sri Lanka, which are highly prone to the respective hazards. Existing global WASH tools such as sphere and global WASH cluster indicators are contextualized, and the toolkit covers three...
The SESAMO early warning system for rainfall-triggered landslides
The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that could be achieved through the use of modern and often low-cost technologies. This work describes an integrated information...
Characterization of dynamic evolution of the spatio-temporal variation of rain-field in Hong Kong
A significant part of Hong Kong has hilly terrain with relatively short flow concentration time and, hence, is susceptible to the threat of flash floods and landslides during intense convective thunderstorms and tropical cyclones. For places like Hong Kong, a rainfall model that could adequately capture small-scale temporal and spatial variations would be highly desirable. The main challenge in rain-field modeling is to capture and describe the dynamic time-space evolution of the rainfall during rainstorm events....
