What is urbanization hydrology?

What is urbanization hydrology?

Key aspects of urbanization affecting hydrology may include: Decreased infiltration and increased surface runoff of precipitation associated with impervious (and effectively impervious) surfaces. Increased speed and efficiency of runoff delivery to streams, via stormwater drainage infrastructure.

What do you know by the term hydrology?

Hydrology is the study of the distribution and movement of water both on and below the Earth’s surface, as well as the impact of human activity on water availability and conditions.

What are the two branches of hydrology?

Branches. Chemical hydrology is the study of the chemical characteristics of water. Ecohydrology is the study of interactions between organisms and the hydrologic cycle.

What happens to urban hydrology in cities?

Urban development significantly increases the amount of storm water and the frequency of extreme hydrological events experienced by the City’s catchments. The increased runoff causes more intense local flooding, while droughts during dry weather are deeper and longer.

What is the effect of urbanization on the hydrologic cycle?

Increased impervious cover associated with urbanization alters the natural cycling of water. Changes in the shape and size of urban streams, followed by decreased water quality, are the most visible effects of increased imperviousness.

How does urbanization affect water?

Urbanization affects water quality because more pollutants are produced in urban settings, and the watersheds lose the ability to hold and retain water because of the increase in impervious surfaces.

What are hydrological factors?

hydrologic factors, e.g., by dilution or concentration such as by evaporation; • biotic factors, e.g., by plant uptake, storage and release, and microbial storage and transformation; and. • geologic factors, e.g., by geochemical reactions.

What are types of hydrology?

Hydrology can be subdivided into the following branches:

  • Chemical Hydrology. Study of chemical characteristics of water.
  • Ecohydrology. Interaction between organisms and the hydrological cycle.
  • Hydrogeology.
  • Hydroinformatics.
  • Hydrometeorology.
  • Isotope Hydrology.
  • Surface Water Hydrology.
  • Ground Water Hydrology.

How does Urbanisation affect hydrological cycle?

What is hydrological impact?

The joint hydrological impacts are similar to those solely induced by climate changes. Spatially, both the effects of land use change and climate variability vary with the sub-basin. The influences of land use changes are more identifiable in some sub-basins, compared with the basin-wide impacts.

How does Urbanisation affect water supply?

Urbanization, in general, has four immediate repercussions on the hydrological cycle: flooding (e.g. as a result of increased soil sealing), water shortage (e.g. due to rising consumption), changes in the river and groundwater regimes as well as water pollution (Rogers, 1994, Strohschon et al., 2013).

What is urban hydrology?

Urban hydrology is a science investigating the hydrological cycle and its change, water regime and quality within the urbanized landscape and zones of its impact. Urban hydrology is a link in a number of sciences dealing with the problems of ecology, environmental protection, conservation and rational use of the water resources of the Earth.

What is the definition of hydrology?

An accounting of the inflow to, outflow from, and storage in a hydrologic unit, such as a drainage basin, aquifer, soil zone, lake, reservoir, or irrigation project. The continuous process of water movement between the oceans, atmosphere, and land.

What is basic hydrologic information?

Basic hydrologic information is a broad term that includes surveys of the water resources of particular areas and a study of their physical and related economic processes, interrelations, and mechanisms. See partial duration flood series.

What is a channel in hydrology?

In hydrology the term is generally applied to the water flowing in a natural channel as distinct from a canal. More generally, as in the term stream gauging, it is applied to the water flowing in any channel, natural or artificial.
