It is the science in charge of the study of the bodies of water found on the planet, specializing in that of the continents. In addition, basins, lakes, rivers, among others, are described, investigated and mapped. Considered one of the most important sciences, they help to have an objective and impartial vision of what large bodies of water are. It is related to other sciences such as geology and climatology.
It is also responsible for separating the seas and oceans from lakes, rivers and basins, that is, salty waters from fresh ones, which only reach 6% of all the waters found on the surface. land. Likewise, it studies the ecosystems of freshwater bodies.
The hydrology, meanwhile, is one of the closest science to hydrography, as is responsible for the study of inland waters and maritime, focusing on its chemical components, its location and the benefits they bring to the population. Both areas of study complement each other; Hydrography needs hydrology to have information on the components of the waters that are studied, their location and ecosystems, thus being able to expand the investigation and specialize in what would be the geographical location of the place.
Hydrography is divided into maritime, river and lake. The first is directed towards the field of studies of the seas and what is related to them; the second is destined to the study of the rivers, streams, deposits and reliefs that they cause; For its part, the latter is focused on the analysis of lakes, their sediments, their environment and the population of fish that reside in them.
