Following is excerpted from a story in The Week.

The Orissa government for the first time would use the Geo Filter Tube (GFT) technology in construction of sea wall to save the Satbhaya village from constant threat of sea erosion.

Chief Minister Naveen Patnaik is scheduled to lay foundation stone of the much ambitious project, estimated to cost Rs 15 crore to the state exchequer, Aul Saline division executive engineer Rajkishore Ghadei said.

Official sources said a high-level scientist team from Chennai-based Indian Institute of Technology (IIT), which earlier visited the sea erosion prone Petha village under Rajnagar, had asked the district administration and the state government to erect a sea wall by using the Geo-Filter Tube technology.

Mr Ghadei … The erosion control measures, he said, would be easily solved by installation of the Geo-Filter Tube erosion barrier. Shoreline restoration is also easily achieved by the installation of the Geo- Filter Tube which acts as a natural sand filter to reduce the insecticides.

It is a low cost shoreline restoration system easy and fast to install with little or no impact on existing landscape at 25 per cent of the cost of the conventional bulkheads or sea walls.

According to Ghadei, the Geo-Filter Tube is constructed of a spun-bond polyester fabric sewn together to form a custom diameter tube. The tube is interconnected along the water-edge, then a small sand pump is used to fill the tube with the same sand and organic material that has been eroding into the lake or canal.

The final result is a long lasting fully contained sand filter barrier that would stabilise the bank from erosion and filter rainwater and irrigation run off.

The Geo-Filter Tube erosion barrier could be installed on any shoreline contour or stacked pyramid fashion to create a more substantial barrier to protect against soil erosion during heavy rains.

The Tubes are geo-textile encapsulated soils used to replace rock as conventional building blocks in marine Geo-tube wall to prevent sea erosion and hydraulic engineering structures,Ghadei.

Following is from a report in New Indian Express.

The State Government has decided to revive the Gopalpur-Digha coastal highway proposal. Announcing this on Monday during question hour, Parliamentary Affairs Minister Raghunath Mohanty said the proposal would be submitted to the Centre for approval after completion of the feasibility report.

Mohanty, who was replying on behalf of Chief Minister Naveen Patnaik, said that the length of the highway will be 573 km. Of this, the Astaranga-Dhamra patch will be 245 km while the length of Astaranga-Gopalpur will be 180 km. The patch of highway from Dhamra to Subarnarekha will be 148 km.

The State Government had earlier submitted a proposal to the Centre and requested that it should be included in a Central scheme. However, the proposal was rejected as it did not confirm to the guidelines of the Planning Commission.
