Hydrology is the study of the amount and quality of water being stored or conveyed on the land surface , and in soils and rocks near the surface. The hydrological response of a catchment is controlled by a combination of climate, vegetation, drainage, soils and land use.
What is the scope of hydrology?
It is the science that treats of the various phases of the hydrologic cycle . Since, hydrology is a science that underlies the development and control of water resources it has its important influence on Agriculture, Forestry, Geography, Watershed Management, Political Science, Economics and Sociology.
What is the study of water called?
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.
Is a hydrologist?
A hydrologist is a scientist who researches the distribution, circulation, and physical properties of the earth’s underground and surface waters . They help environmental and other scientists preserve and clean up the environment, as well as search for groundwater.
What are the basic data required for hydrological studies?
The key variables to be included are precipitation -liquid and solid- (3 or 6 hourly) , discharge (naturalised flow, i.e. streamflow corrected for manmade storage; daily), lakes and reservoir levels, soil moisture, snow water equivalent, snow cover area, snow depth, and evapotranspiration.
What is hydrological process?
The water cycle, or hydrologic cycle, is a continuous process by which water is purified by evaporation and transported from the earth’s surface (including the oceans) to the atmosphere and back to the land and oceans. ... The cycle for water may be short, or it may take millions of years.
What is an example of hydrology?
The definition of hydrology is the branch of science or geology that studies the Earth’s water. The study of how the major bodies of water have shifted, expanded and changed land masses is an example of hydrology.
What is hydrology and its applications?
Hydrology provides guidance for undergoing proper planning and management of water resources . Calculates rainfall, surface runoff, and precipitation. It determines the water balance for a particular region. It mitigates and predicts flood, landslide and drought risk in the region.
Who discovered hydrology?
Pioneers of the modern science of hydrology include Pierre Perrault, Edme Mariotte and Edmund Halley . By measuring rainfall, runoff, and drainage area, Perrault showed that rainfall was sufficient to account for the flow of the Seine.

How many years does it take to become a hydrologist?
Hydrologists must have a master’s degree in environmental science with an emphasis on hydrological courses. Those looking for a teaching or research position typically need a Ph. D. A master’s degree program typically takes two to three years to complete after earning a four-year bachelor’s degree.
Who is a famous hydrologist?
FERRIS , 73, FAMOUS HYDROLOGIST, NATIVE OF WEATHERLY. John G. Ferris, 73, an internationally renowned hydrologist with 42 years of research, field investigation and teaching service with the U.S. Geological Survey (USGS), died March 26 in Suburban Hospital, Bethesda, Md.
How can I learn hydrology?
The candidates must have a B. Tech degree in Civil Engineering/ Environmental Engineering . Apart from the above, the aspirants can also choose different courses in Water Management/ Geography at M.Sc Geography to be eligible for jobs in the field of Hydrology.
How do you collect hydrological data?
Hydrological data are collected by means of a number of technologies ranging from observing gauges, installed at flow measuring points, to automatic data recorders and remote sensing. Transmission of data from international hydrological data collection systems is done by telephone communication, radio, and satellite .
What are the sources of hydrological data?
- Catchment Flood Management plans.
- Climate Records.
- Flood maps.
- Gauged flow records.
- Groundwater vulnerability maps.
- Hydrological summaries.
- MORECS.
- Groundwater level records.
What is hydrological cycle with diagram?
Water Cycle Diagram
The Hydrologic Cycle (also called the Water Cycle) is the continuous movement of water in the air, on the surface of and below the Earth. ... When water condenses, it releases energy and warms the environment. When water evaporates it takes energy from the surrounding environment, dropping temperatures.
