Post your question/information / Atmospheric Rivers
« on: December 23, 2016, 09:15:26 PM »
Atmospheric Rivers can be defined as narrow corridors of concentrated moisture suspended in the atmosphere. It is also known as rivers in the sky. Scientists found that it was responsible for the mysterious mass die-off of wild Olympia oysters in San Francisco Bay in 2011.

For more information, read the article below.

Title :

Atmospheric rivers and the mass mortality of wild oysters: insight into an extreme future?
Abstract :
Climate change is predicted to increase the frequency and severity of extreme events. However, the biological consequences of extremes remain poorly resolved owing to their unpredictable nature and difficulty in quantifying their mechanisms and impacts. One key feature delivering precipitation extremes is an atmospheric river (AR), a long and narrow filament of enhanced water vapour transport. Despite recent attention, the biological impacts of ARs remain undocumented. Here, we use biological data coupled with remotely sensed and in situ environmental data to describe the role of ARs in the near 100% mass mortality of wild oysters in northern San Francisco Bay. In March 2011, a series of ARs made landfall within California, contributing an estimated 69.3% of the precipitation within the watershed and driving an extreme freshwater discharge into San Francisco Bay. This discharge caused sustained low salinities (less than 6.3) that almost perfectly matched the known oyster critical salinity tolerance and was coincident with a mass mortality of one of the most abundant populations throughout this species' range. This is a concern, because wild oysters remain a fraction of their historical abundance and have yet to recover. This study highlights a novel mechanism by which precipitation extremes may affect natural systems and the persistence of sensitive species in the face of environmental change.

In their study titled 'Water Situation in Bengaluru' - published under the ministry of environment & forests' (MoEF's) Environment Information System (ENVIS) in September 2016, it has been reported that as much as 73 per cent of water required by Bengaluru can be obtained from rains alone. The actual demand by the domestic sector is about 20.5 TMC (Thousand Million Cubic feet) per year.

"Way back in 1800, Bengaluru's lakes had a storage capacity of 35 TMC. Our ancestors had built them and interlinked it in such a way that their storage could meet water demand for the next 200-300 years.
However, considering the current status of lakes in and around Bengaluru, they can store only about 5 TMC of water. But over the years, deposition of silt has reduced the storage capacity to a mere 1.2 TMC. There are about 81 lakes in Koramangala valley, followed by 56 in Vrishabhavathi and 46 in Hebbal valley. What is worrying is the considerable increase in built-up area around Bengaluru."

Post your question/information / Cauvery (Kaveri) River Water Dispute
« on: September 27, 2016, 04:17:00 PM »
The sharing of waters of the Cauvery river has been the source of a serious conflict between the two Indian states of Tamil Nadu and Karnataka. The genesis of this conflict rests in two agreements in 1892 and 1924 between the erstwhile Madras Presidency and Princely State of Mysore. The 802 kilometres (498 mi) Kaveri river has 44,000 km2 basin area in Tamil Nadu and 32,000 km2 basin area in Karnataka. Based on inflow Karnataka is demanding a renegotiated settlement based on "equitable sharing of the waters".(more data on pic attached)

The Government of India constituted a tribunal in 1990 to look into the dispute. After hearing arguments of all the parties involved for the next 16 years, the tribunal delivered its final verdict on 5 February 2007.
2007 tribunal verdict
According to verdict, Tamil Nadu gets 419 TMC of Kaveri water while Karnataka gets 270 TMC. The actual release of water by Karnataka to Tamil Nadu is to be 192 TMC annually. Further, Kerala will get 30 TMC and Puducherry 7 TMC.[32] Water to be released to Tamil Nadu according to monthly schedule as: June month (10 TMC), July (34), August (50), September (40), October (22), November (15), December (8 ), January (3), February (2.5), March (2.5), April (2.5) and May (2.5).The Tamil Nadu and Karnataka, unhappy with the decision, filed a revision petition before the tribunal seeking a review.

Article 262 of the Constitution reads as under:

Act of 1956

Video (by Veritasium) tells us about problems in the research, p-values, significance of published articles, why P-hacking is dangerous to science, and why negative(so called boring) results are really important. I will recommend everyone interested in research activities to watch it.

Important Point :
1. A p-Value is only really valid for single measure. once you compare whole slew of variables the probability that at least on of them gives you a false positive goes way up (known as p-hacking).
2. There is no cost to things getting wrong. The cost is not getting them published.- Prof. Brian Nosek

Post your question/information / Restructuring the CWC and CGWB
« on: August 16, 2016, 02:21:10 PM »
Report titled "" submitted to the Water Resources Ministry by committee led by Mihir Shah(member of the erstwhile Planning Commission) proposes to subsumption of both into a new organization.

The proposed National Water Commission will be a science-led agency to advise the States on how much water they can use without affecting rivers and groundwater, taking surface- and groundwater-usage as a single entity. The CWC, established in 1945, is in charge of surface water and creating storage structures such as dams and medium-scale reservoirs. The Central Ground Water Board is tasked with managing groundwater.

Scientific community rejecting new ideas/research is not new thing. It has happened numerous times in past and may happen in future as well. But the beauty of science is that it speaks for itself, loud and clear.

So enjoy reading the below link. :)
