Reverse Waterfall Maharashtra.
Naneghat is a place, located in the Western Ghats of Maharashtra near Junnar in Pune. It is located about three hours from Mumbai. It is a cryptic mountain, from where flows a waterfall in the reverse direction.
Reverse waterfall is a phenomenon in which water is blown upward due to strong wind in waterfalls giving an apparent perception of water flowing upwards. Strong blowing of wind above about 75 km/hr can cause such phenomena.
“Wind speed & force due to gravity are heterogenous dimensionally & hence can’t be compared. it’d be rather, force of wind due to it’s kinetic energy cancels out weight (another force) of falling water”
What Causes Reverse Waterfall
To understand what’s meant by “reverse waterfall” you’ve got to first understand what makes “waterfall” approaches so problematic in many situations.
“Waterfall” approaches are problematic because they require a large up-front cost in ascertaining and defining as many of the requirements as possible and performing both high- and low-level design and specification before any development work begins. This leads to inefficiencies, as often the only way to discover whether or not an approach or solution is the “right” one or even feasible, is to have development teams start working on the solution and to validate their work as they proceed.
“Reverse Waterfall” is the inverse of this — where the development work starts before sufficient research is done, which back-loads the cost of the work, since the developers may be building solutions to problems that the customer doesn’t actually have, or may be building those solutions in a way that does not fully meet the customers’ needs — which means that you have to refactor or redo a lot of your work once you realize this is happening. Thus, there is a lot of randomization and correction that occurs after the development work has started, which is an incredibly expensive way to learn.
The ideal “agile” processes focus on a just-in-time model of requirements gathering and definition. Work shouldn’t start until the problem statement is well-understood, but at the same time detailed requirements and specs shouldn’t be necessary, as you can validate the approach and work performed on a regular basis with customers or customer proxies. You balance the costs of obtaining requirements and of increasing perceived certainty with the reality that you’re only going to know if it works by building it and testing it.
“Reverse Waterfall” tends to be a problem in companies that are very engineering-oriented, and who place too little value on the business analysis needed to ensure that you’re building the right thing at the right time for the right people. As agile practices shift much of the responsibility and authority for determining what work will be done and when it will be done to the development teams themselves, this is a risk that is associated with such approaches.
List of observed location
Australia: A wind of 70 km/h caused reverse waterfalls in various location in Sydney, Central Coast, Mid North Coast, Hunter, Illawarra areas and in the Royal National Park.
- A waterfall at Naneghat in Malshej Ghat Road near Mumbai
- Samrad village in the Sandhan Valley has waterfalls showing reverse waterfall during monsoon.
- Amboli hills near Belgaum have various waterfalls that becomes active in monsoon which gets blown upward due to strong wind.
Hawaii: The Waipuhia Falls in Oahu gets reversed due to north-easterly trade winds.
Japan: Shiretoko National Park in Japan has Furepe Falls to the Sea of Okhotosk. This fall also gets reversed during strong wind.
Brazil: In the Chapada Diamantina National Park the Cachoeira da Fumaça (Smoke Waterfall) shows the phenomenon.
Chile: The waterfall in Talca shows the phenomenon.
United Kingdom: Has been observed in the Peak District amongst other highland areas, commonly in autumn and winter when strong winds can occur. The Kinder Downfall waterfall in the Kinder Scout area of the Peak District regularly exhibits this phenomenon.
