VARANATION: Recorded river engineers and former professors at the Indian Institute of Technology, Banaras Hindu University (IIT-BHU) Prof UK Choudhary have written a letter to Prime Minister Narendra Modi, who asked him to “help maintain the shape of the Ganges River crescent in Varanasi”.
He explained that the shape of the ornamental crescent from Ganga is a unique morphology of the river, and this is the way at least friction resistance, form and tensile strength of pressure from the land of Varanasi.
“This is anatomy that defines the development of centrifugal and centripetal forces in the upper and lower layers of the flow that is responsible for the secondary generation of smooth clay and pollutan particles against the concave bank (city side bank) and sand at convex banks (bedside banks sand), “he added.
He urged PM to help “keep Maa Ganga in the form of a crescent in Varanasi”.
He then explained that the elongated ganga / river water walked circulating and vibrated in the cross-sectional section.
Thus, sustainability in the form of a crescent ganga in Varanasi is only because of Assi and Varuna, Ganga River children.
When ASSI has shifted, Ganga left Assi Ghat forever.
Varuna (responsible for filling erosion bags) and assi (responsible for maintaining sediment burden in suspensions) are needed for protection and conservation conditions for the limit for the shape of the crescent.
This, conceptually, must be realized.
Reminding PM from his statement ‘Maa Ganga Ne Humein Bulaya Hai’ (Mrs.
Ganga called me), Choudhary urged him to help Ganga to maintain the morphology of the original crescent form.
The ASSI River needs to be returned to its original position at Assi Ghat in the form of a river not Nullah.
Regarding the construction of spurs in Lalita Ghat and the development of the channel in the sand bed to facilitate the cargo / ship, he said that the massive work of spurs in Lalita Ghat with different solid materials arranged in different forms cannot create resonance with Ganga.
Thus, the anatomy and ganga morphology has been permanently changed.
The dynamics of the region in the turbulence, are responsible for carrying sediments will be muffled.
This will cause more sedimentation.
Thus, Ganga will leave Ghat in the upstream and sedimentation and recording pollutants will definitely occur in the downstream Lalita Ghat, he argues.
In this way, the shape of Ganga’s sickle will slowly change.
And feller pollutants will be very acute.
The walls made along the Ghats will limit the movement of ground water and water logging problems in the city will increase.
Thus, the work of spurring and channels on the sand bed (built against a centripetal style, secondary current) fundamentally incorrectly.
Choudhary also questioned the efficiency of the waste treatment plant (STPS), said that STP was able to eliminate maximum organic pollutant burden of up to 50% only with some cost of increasing microbiological loads.
And it causes pollution from the fifth of natural constituents.
“Thus, it has been considered one of the main tools for Ganga pollution management.
The recent algae growth in Ganga water is caused by the disposal of pollutants from STP,” he said, adding that the STP system was fully useful only when it was located in the sand bed and Some are useful when it is linked properly with sand beds.
He said that the design of the release of STP, maybe, based on the rainy season period gave birth to waterways.
They need to be based on maximum drain disposal in the Lean period and BOD load from that period.
Quantum treatment pollutant and the current STP period must function at level R (reduced levels) ganga water.
This is because dilution, diffusion and the potential dispersion from Ganga continues to increase by level.
STP, thus need to run almost 8-9 months.
“Investment of several crores from the Rupee under the Gange Namami program such as Ganga Face Washing work.
This investment should be made for the treatment of Ganga’s basic disease,” Choudhary said.
