Falls of the Ohio

-

The Falls of the Ohio was the only major hurdle in Ohio River shipping in the early days of settling in today's United States west of the Appalachians. "Waterfalls" are actually a series of porosities formed by the relatively late erosion caused by a river flowing from the hard limestone rocks created during the Devonian period 386 million years ago. Louisville, Kentucky, and nearby Indiana - Jeffersonville, Clarksville and New Albany - owes their existence to waterfalls, as the barriers to the natural barrier at the end of the 18th century and the beginning of the nineteenth century meant the need for help from nearby residents. Knowing how to handle this 9-meter drop in about three kilometers.

In the nineteenth century, the first waterfalls of the canal with sluices were built, which immediately ensured all-year sailing on the Ohio River, which was important for the settlement of the waterway, and then the waterfalls almost completely disappeared with McAlpine's barrage and locks built by the US Army Corps of Engineers. Adjusting the Ohio River to the height of waterfalls resulted in a decrease in flow velocity, and therefore the risk of spring and autumn floods.

Due to the shallowness of the river at the height of the waterfalls, it was a great ford, used during the pre-eminence times by the herds of buffalo and Indians.

In 1990, the Falls of the Ohio State Park was part of a section of the Indiana River.

indexation

-
Indexing (Latin) - a system of linking wages, prices or interest rates to a specific economic indicator (usually the base inflation rate), a change in the value of this indicator results in a proportional change in wages, prices or interest rates. The indexation can also be described as a conversion of a parameter value (eg pay) based on an indicator showing the change in a factor affecting the value of the parameter (eg inflation). Application The indexation is applied by the state - eg when paying pensions - with the increase in inflation the nominal value of the service increases. The state should also index the boundaries of the tax brackets. When it does not, citizens nominally earn more, but they also "fall into" higher and higher tax brackets, for which they have to pay higher taxes. In addition, when the state does not ideate a tax-free amount, citizens actually pay more and more taxes because the tax base increases. Indexes are used by banks - with the increas...
