When rainwater falls on leaves of trees and plants, it does not fall directly on the ground. They help the groundwater supply recharge, prevent the transport of chemicals into streams and prevent flooding. Stormwater runoff is rainfall that flows over the ground surface. Deforestation plays several roles in the flooding equation because trees . Retaining walls. Here are a few. Stormwater runoff is the number one cause of stream impairment in urban areas. The water drains down the leaves and branches and soaks into the soil rather than forcefully hitting the ground, which decreases the amount of soil that is washed away with the rain. This helps maintain soil health and prevents silt deposition in water bodies. This helps rainwater to flow continuously and prevents flooding of nearby areas. The deep roots help the plant maximize its absorption of H20, while also anchoring it to the ground during strong winds and aggressive rains.

Pack soil firmly around the roots to eliminate air pockets and provide support. They work the way nature does, capturing stormwater runoff so it can soak into the ground. 5. They also provide surface area where rain water lands and evaporates. . Sea / Coastal Defence Walls. Heavy rain or snowmelt can also cause flooding by raising the water level of rivers, and other bodies of water. Trees are Nature's helpers in the task of reducing geomorphological instability and slow down erosion phenomena, and this works for river basins too. They hold the soil together so that erosion is prevented. A sea defence wall can help prevent coastal floods during high tides. It's All in the Grade. Trees allow water to be drained into the ground When plants grow in an area, the roots of plants dig deep in to the soil and create space between soil particles. The Chicago Botanic Gardens recommends planting native perennials with deep root systems to deal with storm-sized influxes of water. They can help: Prevent flooding. There are many plants that are good at preventing floods. The extensive root system of trees absorbs huge quantities of rainwater, thereby preventing floods The roots of trees hold the topsoil together and prevent soil chunks from blocking the rivers and streams. Lots of raindrops that land on leaves evaporate straight into the air- so less water reaches the ground. Flooding is never ideal, but in the wake of the coronavirus pandemic, flooding now poses an increased public health risk. Not only do their canopies intercept some of the rain and reduce its impact, their roots anchor the soil and help take up leached chemicals before they reach the body of water. Look. 3. And, leaves intercept rainfall, slowing the rate that water flows into rivers and reducing the risk it'll burst its banks. Trees help keep soil in place, and their roots soak up water. Level a sloping yard. Shrubs in the riparian zone also help slow flood water. Share.
