What’s a firefall?

You’re right, it is really cool! The firefall is a natural phenomenon that occurs for a few days in mid to late February each year in Yosemite National Park. When the setting sun hits Horsetail Fall just right, the waterfall glows red and orange, as if it’s made of fire.

This year, though, the fall might not turn fiery. As of Feb. 13, there wasn’t enough water flowing, and there’s no rain in the forecast during the dates when the sun would hit at the right angle.

If you’re still wanting to go see it despite the low chance of the spectacle making an appearance, know that it’ll probably be difficult to manage. Last year, thousands of visitors tried to catch a glimpse of the firefall, and the overcrowding caused some destruction, like trampled plants and eroded riverbanks. Park staff hopes to avoid those issues this year by more tightly controlling access to that part of the park.

What effect does deposition have on waterfalls?

The effect that deposition have on waterfalls is the waterfall is really high so the energy in which it holds is much powerful that usual. The depths may vary according to the length of the waterfall, and how deep it is.

What are the white suds on the pool water?

Without seeing your water, I am going to guess that the liquid algaecide you are using is a quat (quatenary ammonium). It is an effective algaecide but it can cause the water to get a little "sudsy" or "foamy". You may have had just a bit too much in there. A way the old service company guys would check your algaecide level was to put their hand in the pool and shake it around. If it foamed some, then you had enough. Usually a good shock will clear that up.

How is a waterfall formed?

Water falls over Hard rock. When it reaches the soft rock, the water starts to wear away the soft rock, this is called erosion. Over hundreds or even thousands of years, the soft rock is slowly eaten away or eroded and the river begins to cut down further into the soft rock. This makes a cliff over which the water can topple. Over time, the cliff becomes steeper as more soft rock is eroded, and deeper as bigger boulders come over the waterfall, and the ground gets beaten with more and more rocks until it creates a plunge pool. Some of the water goes under the waterfall and under cuts the soft rock. More of the hard rock begins to fall away and the waterfall slowly moves upstream.
Water falls are formed when a layer of soft rock is under a layer of hard rock. The soft rock is eroded forming a plunge pool. The hard rock fall in the plunge pool. As this keeps happening both layers stay the same and the water falls to the rivers.

Waterfalls are formed by erosional processes- Hydraulic, corrosion and attrition action. Waterfalls form where rivers meet a less resistant rock, after flowing over more resistant rock. The hard rock eventually collapses into the plunge pool at the bottom and the soft rock is eroded back.
It all starts off on top of a high elevation, such as a mountain, and when it rains the water tumbles down the mountain or hill. Sometimes there is no path for the water to follow so it must fall of the cliff. There is a layer of hard rock underneath the water and soft rock underneath that. The soft rock erodes faster than the hard rock forming a curved ledge underneath the hard rock. A plunge pool would be formed at the bottom once the water had started tumbling down. After some time, the hard rock would erode too, pushing the waterfall upstream over years.
Wherever rain falls the laws of gravity assure that one way or another it will try to reach the ocean. Normally it moves to lower ground by lines of least resistance ie trickle down, first small creeks and streams slowly gathering to meet in a valley to form a river and down to the coast. Sometimes the rainfall on rocky platforms or plateau's can not find a route down hill. This water will gather until there is enough to find the line of least resistance and cascade over the edge of the plateau in a water fall. Over the course of time the rain will gouge out a permanent watercourse at this point

The Olson Memorial Park waterfall was a replica of what waterfall?

Brief History of Olson Rug Co. Olsonrug.com Olson Rug Co. was established in 1874. The manufacturing mill was located in Chicago at Diversey Ave. and Pulaski Road. During the War era, when raw material was scarce, people would send in their old wool rugs, rags, clothing etc. and Olson Rug would turn them into beautiful area rugs. The family-owned business was "the place" to buy rugs for many years. Alongside the factory was the renowned Olson Memorial Park. Walter E. Olson built the 22 acre park in 1935. The project took nearly six months to complete. About 800 tons of stone and 800 yards of soil were used for its construction. Approximately 3,500 perennials were planted, along with numerous species of junipers, spruces, pines, arbor-vitaes and annuals. The park consisted of a stunning rock garden, duck pond and 35-foot waterfall. Olson Park became a popular spot for family outings. During the first Sunday after its dedication, Olson Park attracted as many as 600 visitors per hour. In 1965, Olson Rug sold its building to Marshall Fields. In the 1970's the waterfall was turned off and the park dismantled to make room for a parking lot. Today Olson Rug Co. is a 17-store Chicago based chain whose main business is retail residential floor coverings. Olson Rug sells a wide variety of carpet, area rugs, wood and laminate floors, ceramic tile and vinyl. It was a replica of a waterfall at the Wisconsin vacation home of Mr. Olson. I didn't learn this until years after the park was razed. (My dad used to take us to the park to climb the falls several times a year, and always for the Injun Summer display.) In one of the patient lounge areas funded by the Olson family in Lutheran General Hospital in Park Ridge, there was (maybe still is?) a tapestry of the original waterfall with a plaque explaining the connection.

What are examples of a waterfall model?

We go for waterfall model if the requirement of a problem are reasonably well understood for ex In existing employ payroll system ,if the payroll computing mechanism has to be changed we go for waterfall model
cleanroom software engineering implements waterfall model.
online event management system.
Any project for which complete and consistent requirements are available is amenable to the waterfall model. In general, this will tend to be a very small project. The only large projects that are amenable to the waterfall model would be projects of re-engineering an existing system, therefore all the requirements are known before you start the process.

The reason is that the waterfall model only handles requirements in the first phase of development. In the presence of requirements or technical uncertainty you want to have some kind of iterative process in place, i.e. RUP, Agile, RAD, etc. When requirements uncertainty is present you will start coding and then discover that requirements need to be reviewed or rewritten -- in the waterfall model there is no other phase where requirements get revised.

we can take real life examples for water fall model like automobile companies make cars and bikes. when they are building a car, the requirments are fixed, predecided. there will be no change in the requirments during the process of building a car. Once we complete a stage, we proceed to the next one. if there is any change in requirments come then we have to go back and make those changes. then we have to change our complete system that requirs extra time and extra money. this is a major disadvantage of water fall model.

Fables and Folklore

What is the folklore behind the Bridal Veil Falls in Utah?

A marker at the falls has this on it:

"Many moons ago, an Indian named Norita and a brave from a rival tribe, named Grey Eagle met and fell in love. They planned to meet near a streamlethigh on the mountainside and elope to a land far away from both their tribes. On that fateful night, instead of her lover, Norita was confronted by braves from her own tribe. Fearing her lover had been destroyed she leapt from the high ledges.


Mother Nature was touched by her wild beauty, and she caught up Norita'sstreaming tresses and made from them a Bridal Veil of falling water. From her flowing gown an alter was formed on the face of the mountain. Then her spirit was sent out as a mist, causing a green carpet to spread over themountainside.

The intruders fled while her lover stood and gazed down at the strange yet beautiful transformation. His grief was more than he could bear, so out of compassion for his sorrow, Mother Nature molded his massive frame into the mountain and stretched his mighty shoulders high into the heavens like silent sentinels to guard over his loved one. His cries of anguish were softened into love calls to whisper forever."
