Flooding is defined as the accumulation of water within a water body and the overflow of excess water onto adjacent floodplain lands. The flood- plain is the land adjoining the channel of a river stream, ocean, lake, or other watercourse or water body that is susceptible to flooding
Global Positioning System (GPS) GPS is a global positioning system that uses satellites to pinpoint your location anywhere on the planet. How does it do that? Your GPS-enabled device—such as a cell phone, car navigation system, or handheld GPS unit—determines your location by measuring the time delay between when a satellite sends a signal and when your unit receives it. With more than 24 GPS satellites in orbit around the Earth, GPS has become very popular for navigation on land, sea, and air, as well as an important tool for mapmaking and land surveying.
A floodplain is a land area adjacent to a river, stream, lake, estuary, or other water body that is subject to flooding. This area, if left undisturbed, acts to store excess floodwater. The floodplain is made up of two sections: the floodway and the flood fringe
Any condition, meteorological or otherwise in which normally dry land is covered by standing or moving water. An overflowing of water on an area normally dry; inundation; deluge The flowing in of water from the sea as the tide rises
Occur within a few minutes or hours of excessive rainfall, a dam or levee failure, or a sudden release of water held by a debris jam. Flash floods can roll boulders, tear out trees, destroy buildings and bridges, and scour out new channels. Rapidly rising water can become very deep, depending on terrain. The precipitation that produces a flash flood can also trigger catastrophic mud slides.
Gigantic daughter of the West, We drink to thee across the flood, We know thee most, we love thee best, For art thou not of British blood? —Tennyson Like some full-breasted swan That, fluting a wild carol ere her death, Ruffles her pure cold plume, and takes the flood With swarthy webs. —Tennyson Alone stood brave Horatius, But constant still in mind; Thrice thirty thousand foes before, And the broad flood behind. —1st Baron For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark. —Bible (NewTestament) A branch of one of your antediluvian families, fellows that the flood could not wash away. —Congreve,William 'People can't die, along the coast,'said Mr Peggotty, 'except when the tide's pretty nigh out. They can't be born, unless it's pretty nigh inönot properly born, till flood. He's a going out with the tide.' —Dickens, CharlesJohn Huffam You see how when rivers are swollen in winter those trees that yield to the flood retain their branches, but those that offer resistance perish, trunk and all. —Sophocles
Heavy rains are occurring or are expected and may cause sudden flash flooding in specific areas. Flash Flood Warning - Flash flooding is occurring or is imminent at designated areas.
Floods are sometimes described according to their statistical occurrence. Afifty-year flood is a flood having a magnitude that is reached in a particular location on average once every fifty years. In any given year there is a two percent statistical chance of the occurrence of a fifty-year flood and a one percent chance of a hundred-year flood.
Process of evaluating a potential hazard, likelihood of suffering, or any adverse effects. In addition to the overall frameworks for risk assessment and risk management described here, progress has also been made in many areas, including the use of scientific data to characterize health risks; the principles underlying risk-management decision making; understanding public perception of risk (and differences between public and expert opinion); and the communication of information on risk, and its potential influence on perceived risk.
Flood Zone (Zone) - A geographical area shown on a Flood Hazard Boundary Map or a Flood Insurance Rate Map that reflects the severity or type of flooding in the area.
Banks of a river: Elevated land on the side of a river. This is also known as Valley side.
Coastal flooding: seashore flooding caused by high tides usually brought about by storms
Flood stage--The elevation at which overflow of the natural banks of a stream or body of water begins in the reach or area in which the elevation is measured.
delta: a triangular area of swampy land created here the mouth of a river branches into several streams
Maps are two-dimensional (flat) representations of three-dimensional spaces. People have been making maps for over 4,000 years, and they've come a long way. We used to rely on explorers to visit faraway places before a map could be made. We still have explorers that travel the Earth (and beyond) to discover and map new places, but now we can also make and update maps with information sent from satellites in space. All maps have five basic elements to help you understand them (numbers match image below): 1. A title, to tell you the "who," "where," and "when" about the map 2. Orientation (north, south, east, or west) 3. Scale to determine distance 4. A legend that explains the shapes, colors, and symbols used 5. A grid or coordinates that help show where the map fits into a larger global area
Geographic Information Systems (GIS) GIS is a computer-based technology that enables people to quickly combine different types of information (such as population, precipitation, and transportation) on a single map. GIS represents real-world objects (roads, a house, rainfall amount, land elevation) with digital information, and GIS technology can be used for all kinds of things—scientific investigations, managing natural resources, cartography, and route planning, to mention just a few.
The European Center for Education on prevention of risks of school level was established in 1997 under FORM - OSE to partially open EUR-OPA agreement for large risks to the Council of Europe. Currently the Agreement have joined 23 countries: Albania, Algeria, Azerbaijan, Belgium, Bulgaria, France, Georgia, Greece, Italy, Lebanon, Luxembourg, Malta, Moldova, Monaco, Morocco, Macedonia, Portugal, Russia, San Marino, Spain , Turkey, Ukraine. After the 1990 Open Partial Agreement disclosed in various European countries - not just members of the Council of Europe, a network of centers. The European Center is included in this network. It summarizes the European experience and coordinate activities in the development and implementation of general and partial educational policies, educational concepts and teaching methods in the field of training in prevention of risks to the school level. The center promotes and coordinates the consultation among member states of the Council of Europe, other countries and international organizations in the field of prevention of risks to the school level.
