Hydrology
Hydrology is the scientific
study of the movement, distribution, and quality of water on the Earth
including the hydrologic cycle, water resources and environmental watershed
sustainability. The domains of hydrology include the fields of hydrometeorology,
surface hydrology, hydrogeology, drainage basin management, and water quality.
The hydrologist can engage with in various activities such as earth and
environmental science, physical geography, geology, civil and environmental engineering,
hydraulic modelling, flood mapping, catchment flood management plans, shoreline
management plans, estuarine strategies, coastal protection, and flood
alleviation.

The Water Cycle (Source: http://water.usgs.gov/edu/watercycle.html) |
Branches of
Hydrology are:
☞ Chemical hydrology
is the study of the chemical characteristics of water.
☞ Ecohydrology
is the study of interactions between organisms and the hydrologic cycle.
☞ Hydrogeology
is the study of the presence and movement of groundwater.
☞ Hydroinformatics
is the adaptation of information technology to hydrology
and water resources applications.
☞ Hydrometeorology
is the study of transfer of water and energy between land and water body
surfaces and the lower atmosphere.
☞ Isotope
hydrology is the study of the isotopic signatures of
water.
☞ Surface
hydrology is the study of hydrologic processes that
operate at/near Earth’s surface.
☞ Drainage basin
management covers water storage, in form of reservoirs
and flood protection.
☞ Water quality
includes the chemistry of water in rivers and lakes, both pollutants and
natural solutes.
☞ Oceanography is
the study of water in oceans and estuaries.
☞ Meteorology
is the study of atmosphere and weather including precipitation as snow and
rainfall.
☞ Limnology
is the study of biological, chemical, physical geological of all inland waters.
Hydrological Models
Hydrological Models are simplified and
conceptual representations of a part of the hydrologic or water cycle for hydrologic
prediction and understanding hydrologic processes and behavior of hydrologic
systems to make better prediction and to solve the major challenges in water
resources management. There are two major types of hydrologic models can be distinguished:
☞ Stochastic Models are the black box
systems, based on data and using mathematical statistical concepts to link a
certain input to the model output. Commonly used techniques are regression,
transfer functions, neural networks and system identification.
Surface Water Concept (wikipedia) |
☞ Process-Based Models (known as deterministic
hydrological models) represent the physical processes observed in the real
world including surface runoff, subsurface flow, evapotranspiration, and
channel flow.

If you can translate into khmer version, it'll be very helpful too.

ReplyDeleteYes, but some terminologies are so difficult to translate, haha :)
