An enormous sandpit is created within the flood-prone area. It is there for future use.
Sacks are filled with sand or soil in order to make a sand bags. They are cheap to make and are used to quickly make a wall around a certain area in order to hold the water back, thus preventing a flood.
A flood plain is a flat land bordering a river made up of alluvium (clay, sand and silt) deposited during floods. When a river overflows, the floodplain is covered with water. Hope this helps :)
it turns into dirt and sand.
Some of the sand will sink to the bottom of the water. There is no chemical reaction. However, some of the sand may go into suspension, making the water muddy. This is a physical change that can be reversed by filtering the muddy water.
You can't really.Just get up on high ground and use sand bags to stay asfe.Actually you can, you can stop the flow of the water by building a dam upstream. that is just one of the ways. there are lots of ways
Things like building sand bags and dikes are flood defences.

Bulk bags are most commonly used for rainstorms and floods. In these types of situations, the bulk bags are known as sand bags. Using sand bags helps for residents and roads to not flood.

The fine sediment left behind a flood is known as silt. It is made up of particles that are smaller than sand and can be deposited by the water as it recedes. Silt can have both positive and negative impacts on the environment, depending on the quantity and location of its deposition.
they put sand bags in front of their door to stop the water coming in or the helicopter would come and take them
stay in your house and if you live in a city put sand bags at your front door. dont drive or walk around the town.
Bags and sand are usually provided by local fire departments and safety organizations in areas that are flood prone. As a rule, FEMA doesn't show until after the flood or other disaster that has created an emergency for it to manage.
The answer will depend on how big (or small) the bags of sand are!
it is 100 bags of sand/ballast
