SOIL
A natural barrier made of molten rock as it cools is called a lava dam, formed by solidified lava flows. An artificial barrier built to prevent flooding is called a levee, which is a raised embankment constructed along the banks of rivers or lakes to contain or divert floodwaters.
levees are artificial or natural slopes or walls to prevent flooding of a river.
flooding
A levee is a man-made structure typically built along rivers to prevent flooding by confining the flow of water within a certain area. While it is not a natural landform, it does alter the landscape and impacts natural processes.
A levee is an embankment along a stream that protects land from flooding. Levees can be natural or constructed. A dike is much the same, a protective wall, often to hold back the sea.
A levee is an embankment that helps protect the land from a floodplain. A levee is formed when floodwater deposits material on the banks of a river, which builds up over time. The embankment slowly erodes away which is making rivers and streams wider and it can sometimes create a v-shaped valley.
Psychologically, you need to decide whether or not you can handle pregnancy. Natural birth control doesn't work, because you can get pregnant at ALL times of the month. If you use "artificial" birth control, you need to use it properly to be protected.
Nope... a delta - is the natural mouth of a river. A levee is an artificial bank built up to prevent flooding of low-lying areas.
A dike: 1. an embankment for controlling or holding back the water of the sea or a river 2. a ditch 3. a bank of earth formed of material being excavated 4. a causeway 5. a low wall or fence, especially of earth or stone, for dividing or enclosing land If any of those seems right, just add the river part to it and you got your little definition of River Dike. Hoped I could help.
Natural irrigation refers to the water supplied to crops through natural processes like rain or flooding. Artificial irrigation involves the controlled supply of water to crops using man-made techniques like sprinkler systems or drip irrigation to ensure plants receive adequate water for optimal growth.
Natural is to nature as artificial is to artifice.
The definitions is : Natural- A natural plant Artificial- An artificial one
