Rain and Flooding

The average monthly rainfall in Cornwall for 2010 was around 100-150mm per month. Rainfall can vary depending on the specific location within Cornwall and the time of year.

Yes, Browns Plains was affected by the floods in Brisbane in 1974. The area experienced significant flooding with many homes and businesses affected. The floods in 1974 were one of the worst in Brisbane's history.

Frost weathering, also known as freeze-thaw weathering, occurs when water seeps into cracks in rocks, freezes, expands, and then thaws, causing the rock to break apart. This process is common in environments with frequent temperature fluctuations above and below freezing.

Acid rain in the Black Forest caused significant damage to vegetation, particularly to trees. The acidic precipitation led to forest decline, tree dieback, and soil degradation. This had a detrimental impact on the ecosystem and biodiversity of the region.

It depends on the location and climate. In some arid regions, 60cm of rain in a year would be considered a lot, while in a tropical rainforest, it might be considered average or even below average.

If acid rain continues, it can result in harmful effects on ecosystems, including damage to plants, aquatic life, and soil quality. It can also lead to increased corrosion of buildings and infrastructure, posing risks to human health and the environment. Efforts to reduce emissions of pollutants that cause acid rain are essential to mitigate these impacts.

Hydrologists predict floods by monitoring factors such as rainfall, temperature, snowmelt, soil saturation, and river levels. They use computer models to simulate how these factors interact to forecast potential flooding events. By analyzing historical data and current conditions, hydrologists can make predictions about when and where floods are most likely to occur.

All suburbs along the Bremer River were affected, as well as low-lying area. These areas included Amberley, Bundamba, the Ripley area (it was not a suburb back then), One Mile, Churchill, Sadliers Crossing, parts of East Ipswich, Basin Pocket, Tivoli, Swanbank and parts of Raceview.

The Cumbria floods happened due to heavy rainfall causing rivers to overflow, leading to widespread flooding in the region. The combination of saturated ground and intense rainfall contributed to the severe flooding that affected Cumbria.

Precipitation falling onto Earth returns to the ocean through various pathways, including runoff from rivers and streams, groundwater flow, and direct flow from the land surface. This water eventually makes its way back to the oceans through the hydrological cycle, where it can evaporate again and fuel the formation of clouds and subsequent precipitation.

The main reason why the 2010-2011 floods happened in Australia is, quite simply, because of the unusual amount of rain.

Australia spends many years in drought, often caused by the El Niño effect. When an El Niño occurs, changes in sea surface temperatures cause a shift in air pressure which, in turn, can result in climatic anomalies, such as severe droughts in Australia. These years are punctuated by years of normal rainfall, but occasionally, Australia gets the opposite to an El Niño, which is La Niña. This means that weather conditions, etc, are in reverse to those seen during El Niño, and Australia experiences far more rain than usual.

Australia had been coming out of an El Niño for some time, which means that many parts of Australia had seen gradually increasing rainfall. The rainfall recorded in September 2010 made it Australia's wettest month overall in 110 years. Queensland already experienced flooding in early 2009 (at the same time that southern Australia had the terrible Black Saturday bushfires), and higher than normal rainfall in 2010, increasing towards the end of the year. By then, the ground was simply too saturated to hold any more water. Add to that the effects of the cyclone which crossed the north Queensland coast at Christmas time, bringing excessive rainfall to north and central Queensland, and the ground was waterlogged. (A similar pattern led to the Brisbane floods of 1974.)

Radar images show how large the cyclone system was, even though it was only a category one cyclone, the lowest grade. Low wind speeds do not necessarily mean low rainfall, and in this case the cyclone brought large amounts of rainfall right along the coast. Some of the water runoff from the north flowed down through the inland river system; some of the rainfall fell into the catchment areas of coastal rivers further south. The rivers broke their banks more easily, and there was nowhere for the excess water to go.

Rain continued to fall heavily throughout early January. On 10 January 2011, Toowoomba, a city which sits at an elevation of 700m at the top of the Great Dividing Range, received 150 mm of rain within a 40 minute period. The ground could not hold any more water. Water collected along the escarpment at the top of the range and created the wall of water, a 7m high inland "tsunami", that went through the city and down the range. This wall of water rushed through Lockyer Valley to the catchment areas of the main dam that protects the city of Brisbane from flooding, sending its capacity to 190%. The gates had to be opened, sending the equivalent of two Sydney Harbour's worth of water into the Brisbane River each day. This is largely why Brisbane and Ipswich flooded. An inquiry into the release of water from Wivenhoe is underway.

Many of the river systems further west which were affected by the flooding which had occurred regularly through December and January feed into the Darling River, which then leads to the Murray River. The Darling River catchment, and catchments east of this, received more rainfall than its capacity can take, and as the floodwaters moved downstream, communities in New South Wales, western Victoria and South Australia were affected as well.

Road or pavement surfaces made from rigid material such as concrete, have cracks provided to allow for thermal expansion, and differential movement.

In other words tree roots and the earth's crust move around where ever they want to if one of the squares that is separated by cracks is damaged and cracks all we have to do is replace that one square instead of the whole sidewalk... its kind of like the square carpet idea... if you spill some thing on one square of the carpet you only need to replace that square instead of the whole room of carpet

Flooding is a hazard because when water enters your home, it can damage personal items. It can also bring in molds that may be hazardous to your respiratory system. Flooding is hazardous on roads because when car tires go too fast over water, they hydroplane. Hydroplaning is when you loose control of your tires and usually spin out of control. Hope this answers your query!

Yes, scientists believe that most of Earth's water came from volcanic activity releasing gases like water vapor, which later condensed and fell as rain, filling up the low-lying areas to form the oceans. Cooling of the Earth's surface also played a role in the formation of oceans by allowing the water to accumulate in depressions on the Earth's crust.

Most floods occur in low-lying areas near rivers, coastal regions, or areas prone to heavy rainfall or snowmelt. Urban areas with poor drainage systems can also be at risk of flooding. Flooding can happen anywhere, but certain regions are more prone to experiencing floods due to their geography and climate.

The inland West region, such as the Great Basin and parts of the Western United States, receives little rainfall due to its distance from oceanic moisture sources. These areas are often in the rain shadow of mountain ranges, which block moisture from reaching the interior. Additionally, the dry climate is influenced by prevailing wind patterns and the region's high elevation, which can inhibit the formation of rain clouds.

Water is cycled from the land to the atmosphere through the processes of evaporation and transpiration. Evaporation is the conversion of liquid water into vapor from sources like lakes, rivers, and oceans, while transpiration is the release of water vapor from plants through their leaves.

10 is a good estimate, but it varies depending on, among other things, temperature (particularly in the critical snow-growth region of the atmosphere). It can be as little as about 4, or more than 20.

No, sleet is a type of precipitation consisting of small ice pellets that form when raindrops freeze before reaching the ground. Tornadoes are violent rotating columns of air that form in severe thunderstorms. The formation of a tornado requires specific atmospheric conditions that sleet does not provide.

It can puddle, get absorbed into the earth as groundwater, get used by plants, or runoff.

Groundwater serves as a vital natural resource by providing drinking water, supporting agriculture and industry, and maintaining ecosystem health. It also helps in regulating Earth's temperature and acting as a buffer against droughts and floods.

Ombrophiles is wrong. There is no word as far as I have searched. Ombrophiles is not a word in the dictionary.

Rainfall can vary in different places due to differences in atmospheric conditions, such as temperature, humidity, and air pressure. These variations can result in different amounts of moisture in the air and different mechanisms for precipitation to occur, leading to varying types and amounts of rain in different regions. Geographic features like mountains and bodies of water can also influence rainfall patterns in specific areas.

Hard dry soil is like impermeable rock; it does not let water pass through. Instead, water sits on top, or in the case of a slope, runs down. This then causes flooding.
