Mains level: Enhancing transport with the help of Inland Waterways


  • Moving a step ahead towards ensuring optimum use of National Waterways, the Inland Waterways Authority of India (IWAI) launched a new portal LADIS – Least Available Depth Information System.

Least Available Depth Information System Portal

  1. IWAI has designed LADIS to facilitate the day to day operations of inland vessels plying on National Waterways and to avoid any hindrance in service and operation.
  2. It will enhance credibility and efficiency of information sharing to achieve seamless operations on National Waterways, besides pre-empting problems that may occur during movement of vessels.
  3. LADIS will ensure that real-time data on least available depths is disseminated for ship/barge and cargo owners so that they can undertake transportation on NWs in a more planned way.
  4. The portal being hosted on IWAI’s website has been developed in-house.
  5. Initially LAD information will be available for NW-1, NW-2, Indo-Bangladesh Protocol route and NW-3, along with the date of survey.

Utility of the Portal

  1. An assured depth of waterway is required for seamless movement of vessels.
  2. If real time information is made available regarding LADs in stretches of various NWs, it will help transporters by guiding them on the suitability of time of movement.
