This Innovations Deserving Exploratory Analysis (IDEA) project investigated the use of horizontal wick drains to stabilize slopes and landslides. Several landslide sites, identified with the assistance of the Missouri and Colorado Departments of Transportation and the Colorado Geological Survey, were stabilized by wick drains and monitored. The field experience led to several improvements in the design and installation of wick drains. Simulation and interpretation of rainfall at the test embankment were accomplished and guidelines for wick layout were developed. The results showed that wick drainage was highly dependent on hydraulic conductivity of shallow soil and that drains significantly lowered the water table and reduced soil settlement. Based on test results, guidelines for drain design have been suggested.
