The long profile of a river is not static entity and is prone to change due to changes in sea level. Indeed, a river is already in dynamic equilibrium because things may be balanced over long periods of time but over the short term more or less rainfall can increase or decrease the amount of energy available to the river to move material. Over very long periods of time but over the short term more or less rainfall can increase or decrease the amount of energy available to the river to move material. Over very long periods of time large changes in sea level can drastically alter the rivers potential energy and can increase the chances of vertical erosion. Sea levels change because of 2 principal causes - isostatic changes and eustatic changes, both of these changes can lead to rises or falls in sea level. Isostatic changes are local changes where the height of the land changes relative to the global sea level. An example of this can be found in glaciation. During glaciations the weight of ice pushing on the Earth can depress the crust, causing the land to fall relative to the level of the sea. When the ice goes in warmer periods the land rebounds upwards as Scotland and Northern Britain are today - rising relative to the level of the sea. This process is also seen in deltas where sediment loading depresses the Earth's surface. Eustatic sea level change is a global change in sea level, linked directly to the temperature of the Earth. In warmer periods there is less ice and the water is warmer, so expands and sea levels rise. In colder periods the ocean water is colder so contracts and sea levels fall. When sea levels fall we get raised beaches, abandoned cliffs, erosion surfaces created at the coast, and several adjustments made to river valleys. These changes to river valleys are attributable to the fact that the rivers graded profile is no longer in balance, and the gradient of the river at its mouth is now steeper because of the fall in sea level. In effect the water has further to fall on its journey from source to mouth. This means that there is more energy at the mouth and vertical erosion (which under normal conditions would occur at the river's source) will occur. This leads to the development of knick points, waterfalls, river terraces and incised…
cycle for baritone and accordion entitled "Die Toten von Spoon River".
On June 2, 1957, the CBS Radio Network broadcast a radio adaptation of Spoon River Anthology, "Epitaphs", as part of its CBS Radio Workshop series. The adaptation was directed and narrated by William Conrad, with a cast including Virginia Gregg, Jeanette Nolan, Parley Baer, Richard Crenna, John Dehner and John McIntire.
In 1963, Charles Aidman adapted Spoon River Anthology into a theater production that is still widely performed…

| A stocky freshwater dolphin, characterised by a long beak containing large, visible teeth. Like most river dolphins, this species has little need for vision in the muddy waters it inhabits, and as a result has tiny, non-functional eyes that lack lenses. Individuals use echolocation to detect food and navigate, and – to a very small extent –…
1993 Mississippi Flood
* Most devastating flood in U.S.A history in the Summer of 1993.
* The Mississippi River at St. Louis, Missouri, was above the flood stage for 144 days between 1st April and 30th September, 1993.
* Approximately 3 billion cubic meters of water overflowed from the river channel onto the floodplain downstream from St. Louis.
* Seventeen thousand square miles of land were covered by floodwaters in a region covering all or parts of nine…
Different River Terms
A knickpoint is a term in geomorphology to describe a location of a river or channel where there is a sharp change in channel slope, such as a waterfall or lake. Knickpoints reflect different conditions and processes on the river often caused by previous erosion due to glaciation or variance in lithology.
Knickpoints are formed by the influence of tectonics, climate history, and/or lithology. For example, uplift along a fault over which a river is flowing…

Course of White Water River from its Source to its Mouth
The river starts at Pigeon Rock Mountain.
The river flows in a southerly direction from its source to its mouth.
The height of the land is 348 metres above sea level.
The river has steep valley sides.
It is a V-shaped valley as it is evident on map.
The tributaries that join the river include Yellow water and Pigeon Rock River.

J9: Two Ways of Viewing the River.
This essays discussed about the beauty of the river which was seen in two different ways. He was a young steamboating pilot. This was his first time to see that river’s beauty. He actually felt in love with the scenes along riversides. From its graceful curves to sunset viewing, they made deeply impress on him. He looked bewitched at these sight-seeings. But gradually, with his routines on this river, it was not as beautiful as it had been before…
