Rain and Flooding
Rain is a type of precipitation which is readily absorbed by the ground. However, flooding might occur if there is a downpour or heavy rain. Flooding can result in damage to property, illness and even death.

Where does all fresh water come from?
Fresh water mainly comes from precipitation in the form of rain and snow. This water is stored in various sources such as rivers, lakes, and underground aquifers. It can also come from sources like glaciers, ice caps, and reservoirs.
How can disilting help in flood control?
Disilting can help in flood control by removing excess sediment buildup in rivers, streams, and drainage channels. This allows for better water flow capacity and reduces the risk of blockages during heavy rainfall, which can help prevent flooding by allowing water to flow more freely and efficiently.
Why is runoff more likely to occur after a heavy rain storm?
Runoff is more likely after a heavy rainstorm because the soil becomes saturated quickly, preventing water from infiltrating into the ground. This excess water flows over the surface, picking up contaminants and pollutants before eventually entering nearby water bodies. Additionally, heavy rainstorms can cause flooding, which increases the volume and velocity of the runoff.
Where is wettest place on earth and how much rain does it get in a year?
The wettest place on earth is Mawsynram, a village in Meghalaya, India. It receives an average annual rainfall of around 467 inches (11,871 mm) due to its location on the windward side of the Khasi Hills, which helps capture moisture from the southwest monsoon.
Why rainforists are called rainforists?
Rainforests are called rainforests because they have high levels of rainfall throughout the year, typically more than 1750-2000 mm annually. This consistent rainfall helps to create a lush and dense forest ecosystem with high levels of biodiversity.
How the size of the flood is measured?
The size of a flood is typically measured in terms of the area it covers, the volume of water it carries, and the depth of water at various locations. Hydrologists use tools such as stream gauges, satellite imagery, and aerial surveys to assess the extent and severity of a flood. This information helps in determining the flood's impact and devising effective response strategies.
What is rain sleet and hail called?
Rain, sleet, and hail are all forms of precipitation. They occur when water vapor in the atmosphere condenses and falls to the ground in different forms based on atmospheric conditions.
What percentage of precipitation falls into the ocean?
The total amount of water as a percentage of all the mass that makes up our planet is estimated at 0.023%.
A little over 2/3 of the Earth is covered by water; to be more precise, the consensus is 70.8% (71%) of the surface is water, 29.2 % is land.
How could farmers improve land that has been polluted by acid rain?
Farmers can improve land polluted by acid rain by adding lime to the soil to neutralize acidity, planting acid-tolerant crops, practicing crop rotation to restore soil health, and implementing proper drainage systems to prevent further acidification of the soil. Additionally, using organic farming practices can help to improve soil structure and fertility.
Why does places have more acid rain than others?
Places with more acid rain typically have higher levels of air pollution, such as from industrial activities or vehicle emissions. Factors such as wind patterns, proximity to sources of pollution, and topography can also influence the amount of acid rain a region receives. Areas with higher levels of acid rain also tend to have less alkaline compounds in their soils and water bodies, which can exacerbate the effects of acid rain.
How do you draw easy pictures of water cycle?
To draw an easy picture of the water cycle, you can start by drawing a simple circle to represent the Earth. Then draw arrows to show the movement of water through the cycle: evaporation from oceans and lakes, condensation into clouds, precipitation as rain or snow, and runoff back into bodies of water. Finally, label each part of the cycle to make it clear.
Why does the level of water in wells increase after it rains?
When it rains, the water seeps into the ground and replenishes the groundwater stored in the aquifers. This causes the water level in wells to rise as the aquifers become saturated with the additional water.
Where does monsoons come from?
Monsoons are caused by the seasonal reversal of wind patterns, which brings heavy rainfall to certain regions. In the case of the Indian subcontinent, for example, monsoons occur when warm, moist air from the Indian Ocean moves inland due to a shift in wind direction. This phenomenon leads to a wet summer season in the region.
What impact does acid rain have on northern Europe?
Acid rain in northern Europe can lead to damage to forests, lakes, and buildings due to increased acidity in the environment. It can also harm aquatic ecosystems, reduce soil fertility, and have negative effects on human health. Efforts to reduce emissions of sulfur dioxide and nitrogen oxides have helped mitigate the impact of acid rain in the region.
The placement of rain gauges (in coastal plain and Piedmont regions) should be manipulated to observe and compare the average monthly rainfall accurately.
If the total amount of rain (11 inches) is redistributed equally among the 12 months of the year, each month would receive approximately 0.92 inches of rain.
Why do floodplains often contain fertile soil?
When floods run down they also bring a lot of organic material along with them. Floods also tend to grind up stones/sand to a certain degree.
Where the flood deposits this material it helps fertilize the soil.
A lot of water keeps the soil very moist, which also increases the rate of organic material to decompose (Bacteria and various insects/larva and of course also fungus does this)
Decomposed organic material are the building blocks for new plant life.
As we humans eat dead animals (Meat, although not decomposed), plants "eat" or rather suck up the nutrition from the decomposed material left around.
Who sent the flood and how did utnapishtim find land?
In the Epic of Gilgamesh, the flood was sent by the gods to wipe out humanity. Utnapishtim was warned of the flood by the god Ea, who told him to build a boat to save himself, his family, and some animals. After the flood subsided, the boat came to rest on Mount Nisir, where Utnapishtim and his companions found land.
Why does it rain so much in Quebec?
Quebec experiences a lot of rain due to its location in the northeastern part of North America where it is influenced by various weather systems. The province's proximity to the Great Lakes and the Atlantic Ocean contributes to the moisture in the atmosphere, leading to frequent rainfall. Quebec's diverse topography, including mountains and forests, also plays a role in creating conditions for precipitation.
Is a flood likely to occur over an area that has a high water table or a low water table?
A flood is more likely to occur over an area with a high water table. A high water table means that the ground is already saturated with water, which can lead to faster runoff and increased risk of flooding during heavy rainfall.
How would A river confluence cause flooding?
A river confluence can cause flooding if both rivers experience high flow rates or if one river is blocked by debris at the confluence, causing water to back up and overflow its banks. Additionally, the merging of the two rivers can create a bottleneck that slows down the flow of water, increasing the risk of flooding during heavy rain events.
Which type of rainfall would be most helpful to farmers?
Steady, even rainfall would be most helpful to farmers as it allows for proper water absorption by crops and minimizes runoff. This type of rainfall ensures consistent moisture levels in the soil, promoting healthy plant growth and crop yields.
