School Exercise In Case Of A Flood

A flood is an overflow of water that submerges the area of land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water.

In the sense of “flowing water”, the word may also be applied to the inflow of the tide. Flooding may occur as an overflow of water from many different¬† bodies of water, such as a river or lake, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an a real flood.

While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.

Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers.  That is why it is a good idea to have a Water Damage Defense plan in place. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry.

Some floods develop slowly, while others such as flash floods can develop in a matter of few minutes and without visible signs of rain. Additionally, floods can be local, impacting a neighborhood or community, or very large, affecting entire river basins.

The Most Dangerous Way To Get Home

Risk is the potential of loss (an undesirable outcome, however not necessarily so) resulting from a given action, activity and/or inaction.

The notion implies that a choice having an influence on the outcome sometimes exists (or have existed). Potential losses themselves may also be called “risks”. Any human endeavor carries some risk, but some are much riskier than others.

Risk can be defined in seven different ways

1. The probability of something happening multiplied by the resulting cost or benefit if it does.

2. The probability or threat of quantifiable damage, injury, liability, loss, or any other negative occurrence that is caused by external or internal vulnerabilities, and that may be avoided through preemptive action.

3. Finance: The probability that an actual return on an investment will be lower than the expected return. Financial risk can be divided into the following categories: Basic risk, Capital risk, Country risk, Default risk, Delivery risk, Economic risk, Exchange rate risk, Interest rate risk, Liquidity risk, Operations risk, Payment system risk, Political risk, Refinancing risk, Reinvestment risk, Settlement risk, Sovereign risk, and Underwriting risk.

4. Food industry: The possibility that due to a certain hazard in food there will have a negative effect to a certain magnitude.

5. Insurance: A situation where the probability of a variable (such as burning down of a building) is known but when a mode of occurrence or the actual value of the occurrence (whether the fire will occur at a particular property) is not.

List Of Things More Dangerous Then Sharks

Sharks (superorder Selachimorpha) are a type of fish with a fullcartilaginous skeleton and a highlystreamlined body. The earliest known sharks date from more than 420 million years ago.
Since that time, sharks have diversified into 440 species, ranging in size from the small dwarf lanternshark,Etmopterus perryi, a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark, Rhincodon typus, the largest fish, which reaches approximately 12 metres (39 ft 4 in) and which feeds only on plankton,squid, and small fish by filter feeding. Sharks are found in all seas and are common down to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater, with a few exceptions such as the bull shark and the river shark which can live both in seawater and freshwater. They breathe through five to seven gill slits. Sharks have a covering of dermal denticles that protects their skin from damage andparasites, and improves their fluid dynamics so the shark can move faster. They have several sets of replaceable teeth.
Well-known species such as the great white shark, tiger shark, blue shark,mako shark, and the hammerhead areapex predators, at the top of the underwater food chain. Their extraordinary skills as predators fascinate and frighten humans, even as their survival is under serious threat from fishing and other human activities.
