Why can flash floods occur in desert regions? Desert soil is thin and dry and cannot absorb a sudden rainstorm and there are few plants to absorb water. The rain rushes down hillsides and mountains and overflows arroyos, flowing into roads and homes in its path. They can occur suddenly and areas far from the actual storm can be flooded.esert soil is thin and dry and cannot absorb a sudden rainstorm and there are few plants to absorb water.

Flash Flood Threat Within Fire Burn Scar The time required for a flash flood to begin depends on how severe the fire was and how steep the terrain is, combined with the rate of precipitation. Steep terrain combined with a severe burn scar and light precipitation can result in flash flooding within minutes of precipitation beginning. Areas of less severe burn damage and flatter terrain will be able to absorb more water leading to more time before flooding develops even in heavier precipitation.

- Flooding that is sudden and unexpected is referred to as flash flooding. It is usually caused by slow-moving thunderstorms that deposit an extraordinary amount of water in a relatively short period of time. Due to our location at the foot of the Illawarra Escarpment, Wollongong is particularly prone to flash flooding.looding is when the water level in a creek, river, lake or the sea rises and covers land. Whilst some floods occur without problem, others are devastating, causing large-scale destruction and significant loss of life.

- Temporary loss of the sense of smell is common with colds and nasal allergies, such as hay fever (allergic rhinitis). It may occur after a viral illness. Some loss of smell occurs with aging. In most cases, there is no clear cause, and there is no treatment. The sense of smell also enhances your ability to taste. Many people who lose their sense of smell also complain that they lose their sense of taste.

Deserts Yet more than one billion people, one-sixth of the Earth's population, actually live in desert regions. Deserts cover more than one fifth of the Earth's land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert.Deserts are part of a wider classification of regions called drylands..thers are mountainous. Only about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain. Desert animals have adapted ways to help them keep cool and use less water.

Desert types Deserts are dry places where little rain or snow falls. Some deserts get less than 25 mm (1 inch) of precipitation each year. Other deserts may get up to 250 mm (10 inches) of precipitation. Cold deserts form at higher latitudes. The Patagonian desert in South America and the Gobi desert in Asia are cold deserts.

Do I Know This ? Other large deserts include the Gobi Desert in Asia, the Kalahari Desert in Africa, the Patagonian Desert in South America, the Great Victoria Desert in Australia, the Syrian Desert in the Middle East and the Great Basin Desert in North America.The Gobi Desert is located in the north of China and the south of Mongolia.It is growing at a fast rate due to desertification, a process that turns fertile lands into desert areas. It is caused by humans cutting down forests, droughts, climate change and other environmental factors.ther large deserts include the Gobi Desert in Asia, the Kalahari Desert in Africa, the Patagonian Desert in South America, the Great Victoria Desert in Australia, the Syrian Desert in the Middle East and the Great Basin Desert in North America.

Flash flood A flash flood after a thunderstorm in the Gobi, Mongolia. A flash flood is a rapid flooding of geomorphic low-lying areas: washes, rivers, dry lakes and basins.It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields.lash floods most often occur in normally dry areas that have recently received precipitation, but may be seen anywhere downstream from the source of the precipitation, even many miles from the source.

Thunderstorms Floods are caused by rain, but flooding is more about how much rain falls, how fast it falls, and what happens to the rain after it hits the ground. The most common type of flood that happens during a thunderstorm is a flash flood.Most flash floods are caused be slow moving thunderstorms, thunderstorms that repeatedly move over the same area, or heavy rains from a tropical storm or hurricane.he most common type of flood that happens during a thunderstorm is a flash flood.

Deserts Other cold winter deserts include the Gobi desert in China and Mongolia and the Patagonian desert in Argentina. The lack of rainfall in cold winter deserts is often caused by the rainshadow effect. The rainshadow effect happens when a high mountain range stops moisture from reaching an area.

Why can flash floods occur in desert regions? Why do flash floods occur? The main factors that result in flash floods in deserts and semi deserts are; - sudden, intense rain. Total rainfall amounts (measurements) do not have to be high, even stor … ms of less than .5 inches can cause flash floods, if the rainfall is intense.- topography.esert soil is thin and dry and cannot absorb a sudden rainstorm and there are few plants to absorb water. The rain rushes down hillsides and mountains and overflows arroyos, flowing into roads and homes in its path. They can occur suddenly and areas far from the actual storm can be flooded.

Desert The most famous monsoon is the Indian monsoon. The intense rainfall in these regions can cause massive flooding and destruction of crops. In dry climates, monsoons are an important replenishment for life as water is brought back into drought-stricken zones of the world.he primary mechanism behind a monsoon is a shift in global wind patterns. During most of the year, winds blow from land to ocean making the air dry. Winds originating from land are called continental. During certain months of the year, the winds begin to blow from the ocean to the land making the air moist.

Why Do Floods Occur? Flash floods occur when there is a high accumulation of water in a low-lying area within a period of six hours. These flooding events are potentially dangerous as they often result in swift-moving water knocking down trees and wiping out bridges and buildings.

Flash flood Flash floods are known to occur in the highest mountain ranges of the United States and are also common in the arid plains of the southwestern United States. Flash flooding can also be caused by extensive rainfall released by hurricanes and other tropical storms, as well as the sudden thawing effect of ice dams.Human activities can also cause flash floods to occur.lash flooding occurs when it rains rapidly on saturated soil or dry soil that has poor absorption ability. The runoff collects in gullies and streams and, as they join to form larger volumes, often forms a fast flowing front of water and debris.

- Drought is an abnormally long period of dry weather because there is a severe lack of water in an environment over an extended period of time.For a drought to happen, it means that rainfall has fallen below the average necessary to water crops and/or livestock, and to refill dams for months at a time.f a drought has a geographical cause, it is not called a drought but a desert. Natural deserts tend to occur in the rain shadows of mountains, far from oceans, or under Hadle … y Cells. With the exception of problems caused by volcanoes, the weather phenomena caused by geographical features usually remains constant.

Why does a mirage happen in the desert? It is due to the phenomena of 'total internal reflection'. On a very hot day in a desert, the air just in contact with sand is hotter than the air above it due to the high temperature of sand. This causes the refractive index of the air in contact with the sand to be lower than that of the air above it.

What causes flash floods? What causes flash floods? Find out what causes flash flooding and why it can be so dangerous. Flash flooding happens when rain falls so fast that the underlying ground cannot cope, or drain it away, fast enough. Roads can become like rivers and if there is a lot of water, it can flood buildings and carry cars away.

All About Monsoons The intense rainfall in these regions can cause massive flooding and destruction of crops. In dry climates, monsoons are an important replenishment for life as water is brought back into drought-stricken zones of the world. Part of the reason India gets such an intense monsoon season is due to its elevation.The higher the land mass, the higher the likelihood of the development of a low pressure zone.nswer: Monsoons, or rainy seasons, are a shift in wind direction which causes excessive rainfall in many parts of the world including Asia, North America, South America, and Africa.

Arroyo (creek) A flash flood hits a dry streambed in the Gobi Desert. An arroyo (/əˈrɔɪoʊ/; Spanish: [aˈroʝo], brook), also called a wash, is a dry creek, stream bed or gulch that temporarily or seasonally fills and flows after sufficient rain. Flash floods are common in arroyos following thunderstorms.

- Some deserts located by mountains and are caused by the rainshadow effect. As air moves up over a mountain range, it gets cold and loses the ability to hold moisture -- so it rains or snows. When the air moves down the other side of the mountain, it gets warmer.

- Desertification can cause flooding, poor water quality, dust storms, and pollution. All of these effects can hurt people living near an affected region. (The Facts of Desertification and United Nations Convention to Combat Desertification, 2000) In the Sahel Desert, desertification is becoming a huge problem. Around the 1950’s, people settled into the Sahel region, in areas where there was water.
