Concept in Definition ABC

The term 'ravine' is used to refer to a type of geographical feature that is characterized by the training of a channel or a depression in the ground caused mainly by the continuous or sudden erosion of a course of Water (a River, a spring, etc.). The ravine is always irregular and its size or extension can vary over time according to how the river bed or the watercourse that affects it also varies. The ravines are also usually dangerous spaces for man and animals since the I usually it is not sturdy and can cause collapse or precipitous falls.

The ravine is usually moderate in size but this does not apply to all cases, there are exceptions to the rule. In some cases, the ravine takes a definitive shape from the consolidation of territory in certain parameters. But in others, the ravine can be formed by a sudden situation and vary when this situation disappears or subsides. The ravine always supposes a fall of a more or less important height, the end of the

land surface and the precipice (which on certain occasions may be smaller). In most cases, the fall is quite steep since the ravine being caused by erosion, this decreases the height of the land and leaving high walls of earth on its sides.

It is important to try to fill the ravine as much as possible to avoid accidents gravity for those who must cross it. In some opportunities, the ravines are unrefillable since the lower ground space is very spacious, almost like a small Valley that can be spread for miles. However, in the case of small ravines, of a couple of meters, filling them in is always advisable.
