What is surface hydrology?

Surface hydrology is a branch of hydrology that focuses on the study of the waters found on the earth’s surface, such as rivers, lakes, streams and reservoirs. This discipline is fundamental to understanding the processes that affect the availability and quality of water, as well as the sustainable management of water resources. In this article, we will explore the definition and relevance of surface hydrology, as well as the key components of the surface hydrological cycle.

Definition and Relevance of Superficial Hydrology

Surface hydrology refers to the scientific study of the distribution, movement and properties of water on the earth’s surface. This field analyzes how rainwater and other forms of precipitation become surface runoff, infiltration and storage in surface water bodies. Surface hydrology includes the study of the physical, chemical and biological processes that influence the behaviour of water on the earth’s surface.nnThe relevance of surface hydrology is multiple and covers various areas of interest.First, it is essential for the planning and management of water resources, allowing a better understanding of the availability of water for different uses, such as human consumption, agriculture and industry. In addition, surface hydrology is crucial for the management of risks related to floods and droughts, helping to anticipate and mitigate the negative impacts of these extreme events.nnAnother area of relevance is the protection of the environment and the preservation of aquatic ecosystems. The quality of surface water can be affected by various human activities, such as agriculture, urbanization and industry. Surface hydrology provides the necessary tools and knowledge to monitor and improve the quality of water, thus ensuring the associated health of ecosystems.

Key Components of the Superficial Hydrological Cycle

nThe surface hydrological cycle consists of several interconnected components that describe the movement of water from the atmosphere to the land surface and back to the atmosphere. One of the main components is precipitation, which includes all forms of water falling from the sky, such as rain, snow and hail. Precipitation is the primary source of water for surface water bodies and its magnitude and spatial and temporal distribution are determinant factors in the surface hydrological cycle.nnThe surface runoff is another key component and refers to water flowing on the surface of the soil, heading towards rivers, streams and other bodies of water. The runoff occurs when the precipitation exceeds the ability to infiltrate the soil, and its magnitude can be influenced by factors such as topography, soil cover and use of the soil. Corruptity plays a crucial role in the transport of sediments, nutrients and pollutants to the bodies of surface water.nnnThe surface storage includes all bodies of water on the earth surface, such as lakes, reservoirs and wetlands, which act as temporary reservoirs of water. These natural and artificial reservoirs regulate.
