Among the different geographical formations that occur on planet Earth, the delta is undoubtedly one of the most interesting. When we talk about delta we are referring to that training that arises at the mouth of a River to him sea and that is characterized by the formation of numerous channels or branches of that river. This forms a species network of small branches of the river that all go towards the sea.

Normally, the formation of a delta in a certain area has to do with the natural dragging of sediments that makes the Water and that it tends to form parts of land that can be more or less firm. Thus, the original river ends up dividing into many small arms that cross these sediment remains and continue their course towards the sea where they all come together again. Logically, the abundant presence of sediments makes the river bed less speedy and calmer, being able to take advantage of it from the human point of view in a more accessible way. In many cases too, and depending on the

firmness From the piles of sediments, access spaces can be established for man to inhabit.

Deltas can also be formed by the action of water on land, in which case the erosion it is underwater and takes thousands of years. A characteristic example of this type of delta is the one that forms in the Ganges River, in India. Other famous and very important deltas are those that are formed at the culmination of the Nile River (Egypt), in the Mississippi (USA), the Amazon (Brazil), the Tigre (Argentina), the Paraná (Argentina), the Ebro (Spain) or the Volga (Russia). All these are just some of the existing deltas since in many spaces where the river connects with the sea this geographical formation appears.
