In decades past they have dealt with the red-lining of leases on the richest oyster beds and waterways.
Amongst all, Tsallis entropy based velocity distribution developed from a generalized form of informational entropy exhibits universal validity to sediment-laden flows in wide alluvial open channels, and is found to be superior to others to predict velocity profiles in large waterways with unmanageable rough beds.
"Just like in landfills, if a tampon or pad ends up in a waterway, it can just get embedded into the ocean bed or riverbed and it won't go anywhere for hundreds of years," Shreejaya said. .
The Sleaford Navigation Trust has been working towards restoring the whole waterway, and succeeded in purchasing the Sleaford end of the river bed in 2004.
