River carrying capacity is such a crucial factor in deciding if certain areas will be flooded and with what severity. This capacity is constantly changing, more so in tropical climate and high silt carrying rivers of South Asia, as new research shows. However, most models that are used in India, including by CWC, assume steady state situation. Nor are there constant and credible efforts to assess the river cross sections and river conveyance capacities and put them in public domain. The study shows how important it is that we wake up to this reality and ensure credible, consistent monitoring and assessments by credible independent agencies at the earliest. This has become even more urgent, the study underlines, since in changing climate, the rainfall patterns are changing fast.
The latest update from IMD[i] on Very Severe Cyclonic Storm VAYU (issued at 0700 hrs on June 13, 2019) does not provide any specific risk of floods in any region, nor does it mention any possibility of persistent rainfall leading to risk of floods.
Another IMD update at 1200 hours on June 13, 2019[ii] says large parts of coastal Saurashtra may experience winds of 160 kmph starting June 13 afternoon, but there is no mention of risk of floods. It does give heavy rainfall warning: “Widespread rainfall with heavy to very heavy falls at few places and extremely heavy falls at isolated places in the coastal districts of Saurashtra” till 0830 hrs on June 15, 2019, in RED colour, the highest risk colour code used by IMD. Further this warning adds: “Flooding of escape routes. Minor disruption of railways, overhead power lines and signalling systems.” Among action suggested it lists: “Inundation of low lying areas along the above mentioned coastal districts due to heavy rainfall and storm surge… Evacuation from low lying areas of the above mentioned Districts, coastal Hutment dwellers, urban slum dwellers and people staying in unsafe house to safer places.” The Ministry of Earth Sciences also sends out these releases through PIB Press Notes as IMD functions under MoES.

A report of groundwater pollution in Luna village accessed by Paryavaran Suraksha Samiti (PSS) has once again pointed to the alarming rate of groundwater contamination in the industrial belt in Padra in Vadodara. The report accessed through RTI found that that the Chemical Oxygen Demand (COD) level in groundwater was an alarming 2225mg/I and 27222mg/I in October and December 2018.
It should be noted that even in treated effluent water the accepted levels of COD is 250 mg/I. For ground water the level should be nil. The report was a result of joint investigation carried out by the Gujarat Pollution Control Board (GPCB), Paryavaran Suraksha Samiti (PSS), Farmers Action Group (FAG) and affected farmers in October and December 2018.
PM Modi inaugurated the first multi-modal terminal on the Ganga river in Varanasi on Nov. 12 under a project aimed at promoting inland waterways as a cheaper and more environment-friendly means of transport. The multi-modal terminals are being built as part of the central government’s Jal Marg Vikas Project that aims to develop the stretch of the river Ganga between Varanasi and Haldia for navigation of large vessels weighing up to 1,500-2,000 tonnes. https://www.ndtv.com/india-news/pm-modi-to-inaugurate-1st-multi-modal-terminal-on-ganga-river-in-varanasi-1944924 (9 Nov. 2018)
Explaining the negative impact of waterways projects on Ganga River, Shripad Dharmadhikary in Hindi report titled जलमार्ग परियोजना बदहाल नदियों पर एक हमला writes that the projects lack public consultation “गंभीर बात है कि जलमार्ग विकास से सबसे ज्यादा प्रभावित होने की सम्भावना स्थानीय जनता को है। इसके बावजूद जलमार्ग के विकास से संबंधित ज्यादातर कामों के आयोजन और क्रियान्वयन के लिए न तो इनकी सलाह ली गई है, और न ही इनके बारे में जनता को जानकारी दी गई है। कुल मिलाकर इन जलमार्गों के सामाजिक और पर्यावरणीय प्रभावों का ठीक से आकलन नहीं हुआ है, ऊपर से इन्हें पर्यावरणीय मंजूरी के दायरे से बाहर रखा गया है और सारी प्रक्रिया में लोगों की सहभागिता का भी पूरा अभाव है। ऐसे में जलमार्गों के रूप में इतना बड़ा हस्तक्षेप हमारी नदियों पर एक और बड़ा हमला है जो पहले से बुरी हालत में हैं। https://www.downtoearth.org.in/hindistory/%E0%A4%A8%E0%A4%A6%E0%A5%80%E0%A4%B9%E0%A4%82%E0%A4%A4%E0%A4%BE-%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AF%E0%A4%BE%E0%A4%B8-62034 (5 Nov. 2018)
