Lakes and Rivers

Lakes are huge water bodies that hold a large amount of fresh water. Rivers are water bodies that flow according to gravity, usually ending at a larger body of water such as the sea or ocean.

Are there Great White Sharks in Lake Washington?

Well I think mayby but i also think no.Becase i have never heard that a shark would be in a lake

Actually, sharks can usually only live in salt water. Lakes are fresh water. Therefore, no, they are most likely NOT in Lake Washington.

What is meant by water divide.give an example?

Any upland or a mountain separating two adjoining drainage basins is known as water divide. The Indus, the Sutlej and the Brahmaputra rivers rise very close to each other near the Mansarovar Lake but because of the water divides they flow in different directions.

What is river lift system?

In a River Lift System, water is directly drawn from the rivers for supplementing irrigation in regions near the river. This system is adopted when canal flow is insufficient or irregular due to inadequate reservoir release.

How deep is 1 meter?

One metre is 3 feet 3.37 inches.

If you are standing in a water 1 metre deep you would not drown, it would come somewhere around waist height.

Rain and Flooding
Geography

Why does river straightening reduce flood risk?

Straightening of river reduces floods in the immediate area because it allows the water to go straight instead of having to turn through curves. A natural meandering river has a curvy or sinusoidal shape to its path. A straight river would travel only a kilometer per kilometer of valley floor. Water associated with a curvy river will have to follow the natural sinusoidal curves and will travel considerably more distance per kilometer of valley floor. Also, water in a natural river will have a slower velocity because the course of the river is altered with every curve. A straight river sheds water faster from the immediate area because it has less distance to travel and is not slowed by the curves, however the straightening a river is associated with negative consequences including increased risk of flooding downstream and increased erosion.

Increasing the velocity causes more erosion. If a river is straight then erosion digs the river into a deeper and deeper channel. A curvy river is typically has a slower velocity and erodes less. Also the erosion in a curvy river is associated with the 'cut bank' or outside of each curve not with a deepening channel as seen in straightened rivers. If you imagine yourself as a water molecule traveling down the river when you arrive at the outside of a curve your inertia will cause you to run into the 'cut bank' until the outer bank slows your speed and alters your course. You may have caused a slight bit of erosion but because you keep hitting curves you can not build up the speed needed to induce much erosion. After eroding from the "cut bank" sediment is often deposited in the 'point bar' or inside of the next curve. This causes the curves to slowly meander sometimes leaving 'ox bows' or multiple channels. Building roads or structures in these meandering curves is unwise as inevitably erosion will destroy the structure. The fast moving waters of a straight river can carry far more sediments down stream because of the increased velocity. Straightened streams often had to be lined with concrete or 'rip rap' where the original curvy river did not because the high velocity induced severe deepening of streams and both banks would then collapse in.

Straitened rivers increase the risk of flooding downstream. A straight river or stream holds less water per distance unit of valley floor than a natural and curvy river. In a rain event a natural curvy river will hold more water. Also, since it is not slowed by the curves of a natural river, a straight river will shed what little water it holds faster. This is exacerbated by the draining of wetlands upstream and the tiling of agricultural lands to shed standing water. Wetlands and intermittent pools act as large sponges, holding and delivering rain and snow-melt slowly to downstream rivers. Furthermore, the loss of flood planes by building levies causes rivers to rise higher during flood events and again delivers more water downstream in a short amount of time.

Floods downstream have become more 'flashy' and acute because of straightening of rivers, building of levies and draining of wetlands. A rain event in the Midwest of North America prior to European settlement would have induced far less of a flood height down stream than the same rain event would cause today. This is because the water would be delivered to downstream locations slowly over a greater duration of time.

What is the worlds largest watershed?

According to Wikipedia, the three largest river basins/watersheds by area in descending order are: the Amazon basin, the Congo basin, and the Mississippi basin.

However, if you list rivers by drainage area, you get:

Amazon - 6,915000 km2

Río de la Plata - 4,144,000 km2

Congo - 3,680,000 km2

Nile - 3,349,000 km2

Ob - 2,990,000 km2

Mississippi - 2,980,000 km2

How do rivers create new landforms?

Flowing water contains sediment. Sediment eventually forms different kinds of landforms depending on where it was deposited.

What is so special about Amazon River?

It is the second longest river in the world.

As well as being the second longest river in the world, it has many roles, like watering many different diveristies of animals, from minor animals right up to the large animals such as the big cats of south america. It also has one of the largest spreads of area fed.

Houses many different animals, such as the boto(amazon river dolphin), piranha, and some bull sharks.

Also accounts for around one fifth the worlds river flow

The Amazon river spans 3 countries...Brazil, Colombia, and Peru.

Definitions

What term describes a stream or small river that flows into a larger river?

A small freshwater river or stream flowing into a larger river is called a tributary or feeder river. A tributary is a stream or river that flows into a mainstem (or parent) river or a lake. For example, a tributary can be a creek that flows into a river. Or it can be a small river that flows into a larger river. A tributary does not flow directly into a sea or ocean. Some large rivers can have up to 100 tributaries.

The spot where the smaller and larger river meet is called a "confluence".

In contrast, a body of water that branches off and flows away from the main river is called a distributary.

Care of Fish

What do you feed wild fish?

What to feed a fish is not dependant on whether it was wild caught or captive raised, you feed a fish based on whether it is a predator, omnivore or herbivore. Though wild fish will more often need fresh foods, instead of prepared. At least when first aquired.
