These methods include planting vegetation to retain excess water, terrace slopes to reduce slope flow, and building alluviums (man-made channels to divert water from flooding), construction of dykes, dams, reservoirs or holding tanks to store extra water during flood periods.

How can groundwater flooding be prevented?
If you want to protect your home from flooding, check out these tips.
- Get Appliances off the Floor. You may not have to actually do anything to stop groundwater from flooding your basement.
- Install a Sump Pump. There are different types of sump pumps, but all of them redirect water.
- Fill the Basement.
- Raise the House.
How do dams control floods?
Dams protect against flooding by collecting and holding waters when they reach a certain level. Once collected, a dam might be designed to release the water back into the river at a controlled speed or divert the water elsewhere for other uses. One example of this is a flow-through dam, also known as a perforated dam.
Where was the flooding in Michigan?
It also warned of potential street flooding. A June 25 and 26 storm damaged thousands of homes and ruined hundreds of vehicles. The brunt of the rainfall hit Detroit, Dearborn, Garden City, Ypsilanti and the Grosse Pointes. Wayne and Washtenaw counties were declared a national disaster area.

What conditions create groundwater flooding?
Groundwater flooding is caused when the water table rises up from rocks or soils to above ground level, causing flooding to occur at the surface. This tends to occur after season-long periods of high rainfall. The rainfall infiltrates into the ground causing the water table to rise in response above normal levels.
How do you divert groundwater?
- Dig a Swale. A swale is a shallow trench that redirects water to where it can be safely released.
- Construct a Dry Stream. Like swales, dry streams redirect water and prevent runoff damage.
- Grow A Rain Garden.
- Build a Berm.
- Route Water Into a Dry Well.
- Lay Pervious Paving.
How do dams impact river floods?
Dams can harm the quality of the river’s surface waters, habitat in the river, and water flow. A dam can inundate wetlands and riparian areas in upstream areas of the waterway while reducing or eliminating downstream flooding needed by some wetlands and riparian areas. They can also impede or block fish migration.
Is the Grand River system prone to flooding?

Floods can occur in all seasons: during the spring melt, following major rainstorms in summer and fall, and during a rapid melt or because of an ice jam in the winter.
