INLET DYNAMICS & SHOAL PROCESSES – A COMPLETE NUMERICAL, LABORATORY AND FIELD STUDY
Problem Addressed :
India faces huge navigational, dredging and environmental problems due to siltation at tidal inlets and river confluences. The objective of this projects is to understand the inlet dynamics by concurrent application of numerical, laboratory and field studies and to create tools to model the shoaling process in order to predict operation difficulties. The work is relevant to river ports and Inland Water Transport. If the targets of Sagarmala and IWT was to be achieved and maintained, this is one area that needs to be addressed immediately.
Relevance under Sagarmala :
This activity is relevant under Connectivity Enhancement. This will also have impact in Community development and Port-linked Industrialization.
Why now :
The first phase of IWT is being implemented in India. GOI envisions that the share of water transport shall increase significantly with the more than 14,500km long waterways of India. Understanding and managing the inlets and confluences of the waterway will be a major issue if the WT needs to be carried out in a smooth and efficient manner. Globally, there is limited understanding of the issues related to inlets. Hence, this activity needs to be taken up urgently.
Current Status in India :
IITM has worked extensively on the land water interface issues. They have also developed computational tools. Not many reported works have been carried out in India from other organizations.
Global Status :
Several studies have been reported from America and Europe. Most of the reported literature is on empirical methods which have limitations.
Timelines of completion :
The field and laboratory studies will be completed by 2019. They will feed into numerical models which will be completed by 2020.
Key competencies and stakeholders involved :
Coupled numerical analysis, physical modelling and field measurements. Involvement of major ports and waterways will be there in terms of measurements and field data. Coastal community may be involved where the community faces issues due to inlet behaviour.
Short Term Impact :
Solutions to inlet management in terms of technology and cost.
Medium Term impact :
Seamless integration of IWT and coastal shipping – a success story.
Long term impact :
Major Player in providing solutions and enhancement of IWT capacity.
Physical location of the project :
NTCPWC, IITM Campus. The field measurements will be carried out at identified locations of NW-1.
Development of a customizable 3D numerical Hydrodynamics and Siltation tool
Availability of complete numerical models for day to day use by industry and academia is lacking. This is the main issue addressed in this project.
