Hydrology (from Greek: Yδωρ, hudōr, "water"; and "όγος, logos, "study") is the study of the movement, distribution, and quality of water throughout the Earth, and thus addresses both the hydrologic cycle and water resources.
hydrology
[geography] The study of water, its behavior, and its movements across and below the surface of the earth, and through the atmosphere.
From Floodplain Hydrology to River Analysis
Overview
Bentley provides thousands of engineers with HEC software, documentation, and support for a variety of modeling tasks, from floodplain hydrology to river analysis to GIS integration.

Hydrology: Map data that describes the positions and characteristics of bodies of water.
Hydrology is concerned with study of the motion of the earth's waters through the hydrologic cycle, and the transport of constituents such as sediment and pollutants in the water as it flows.
Hydrology is the science that studies the Earth's water molecules and their movement through the hydrologic cycle. The Earth and its various abiotic and biotic systems are greatly influence by water.
In hydrology applications, another name for linear referencing. River addressing allows objects such as gauging stations to be located by their relative positions along a line feature.

[LINK] Using scanned aerial photographs as a visual guide, you can ask a GIS about the geology or hydrology of the area or even about how close a swamp is to end of a street.
Oil and gas exploration, hydrology harnessing, timber management, and mining operations require sound assessment to steer growth into areas that can support it while preventing contamination of rivers or destruction of resources.
This information has wide applications: in geology (e.g., correlating with plate tectonics effects); in geophysics (e.g, distribution of isostatic imbalances); in climatology (e.g. ocean circulation; orographic barriers), in hydrology (e.g.

There are many different fields within the discipline of Geology, and it would be hard to list all of them. Some include, however: geochemistry, hydrogeology (or geohydrology), petroleum geology, economic geology, soil science, climatology, ...
The system includes forest stands, all roads, hydrology and political boundaries, which allows use of the system for management activities such as harvest, planting, vegetation suppression, thinning and road construction.
Some of the various fields that use ArcGIS Geostatistical Analyst include agriculture, geology, meteorology, hydrology, archaeology, forestry, oceanography, fishery, health care, and environmental studies.
Hydrology:
The science of Earth's water, its movement, abundance, chemistry and distribution on, above and below Earth's surface.
