Tailings and Mine Waste ‘10
This event in Vail, Colo. is the next in a series of symposia on mill tailings management started at Colorado State University in 1978.
The conference objective is to provide a forum for presenting the state-of-the-art regarding mill tailings and mine waste, and to discuss current and future issues facing the mining and environmental communities.
The scope of the conference includes: mill tailings, waste rock, ore, and other mined materials, containment systems (including geosynthetic and composite liners, leak detection and collection systems, and groundwater protection), and permitting issues.

6th International Congress on Environmental Geotechnics (6ICEG)
The Indian Geotechnical Society (IGS) will host the 6th International Congress on Environmental Geotechnics (6ICEG) in New Delhi, India on behalf of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). More than 400 delegates, including 250 from abroad, will gather to discuss the latest geotechnical developments.
The 6th Congress is titled “Environmental Geotechnics for Sustainable Development,” with these eight technical themes: MSWs and landfills, slurry ponds; contaminated land, groundwater, and abandoned landfills; geosynthetics and other new materials; sustainability-professional practice and education; geohazards-disaster mitigation and management; testing, monitoring, and performance evaluation; physical and numerical modeling.
The Congress will have four days of technical sessions (Monday-Thursday) and one day of field visits (Friday). The Congress will be held in a five-star equivalent environment, the India Habitat Centre in New Delhi.

Drainage and filter components for green roofs
Sponsored by IFAI Expo
The Purpose of Drainage for Green Roofs
- Manage rainfall without sustaining damage from erosion/ponding of water
- Provides void space and slope to transport subsurface water
- Connects to roof drains, gutters, and scuppers and conducts water away from roof
- Removes surface water from impervious surfaces
- Maintains optimum growing conditions in the planting media
The Purpose of Filter for Green Roofs
- To prevent fine planting media particles from washing into the drainage layer
- Prevents the reduction or clogging of drainage capacity
- Usually a nonwoven geotextile, occasionally a woven fabric, is used
Filter Components
For retention:- The geotextile must have small enough openings to adequately retain the planting media
- If not, soil particles will eventually clog the drain core
For permeability:
- The geotextile must have large enough openings to allow unimpeded flow of water
- If not, hydrostatic pressure will build up and the planting media will not drain
What are Geocomposite Drains?
- A manufactured material that combines geotextiles and a polymeric core
- The core composition varies in design and material
- Geotextiles may be applied to one or both sides using heat bonding or adhesives
- Geotextiles can filter, protect or hold water
- Geotextiles are available in sheets or rolls that are overlapped or joined during construction
