Hydrology

The Process Of Hydrology

Hydrology is the study of water and its properties, including its distribution and movement in and through the land areas of the earth. In layman’s terms, hydrology deals with both surface drainage and flooding. Surface water runoff is first handled at the local level by either a city or province through a storm drain system (i.e. gutters, culverts, storm drain pipes etc.). As surface water is collected it feeds into a larger system (i.e. large diameter pipes, channels, etc.) that are typically the responsibility of a province flood control or similar entity.

Flooding on the other hand deals with flood risks as they pertain to flood hazard areas or zones, failure of a levee or dam, and inundation caused by seiche, tsunami, or mudflows. Flood effects can be local, impacting a neighbourhood or community, or very large, affecting entire river basins.

The central theme of hydrology is that water circulates throughout the Earth through different pathways and at different rates. The most vivid image of this is in the evaporation of water from the ocean, which forms clouds. These clouds drift over the land and produce rain. The rainwater flows into lakes, rivers, or aquifers. The water in lakes, rivers, and aquifers then either evaporates back to the atmosphere or eventually flows back to the ocean, completing a cycle. Water changes its state of being several times throughout this cycle.

Hydrologists are employed in the management of water resources, wastewater systems, and irrigation projects. The public use of water for recreation and power generation also calls upon the study of hydrology, allowing hydrologists to assist governments and private companies in controlling and managing water supplies. Hydrologists in the field use a variety of techniques, some of them simple and others involving the most cutting-edge modern technology. They may make use of highly sophisticated computer models and satellite remote-sensing technology, or they may apply relatively uncomplicated methods for the measurement of snow depth or the flow of rivers and streams.

Liquids, especially water can manifest in the most unwanted places. Where access is almost possible, Gast can provide the technology to control the situation. Contact Gast for more information on mining and hydrology today.
