Floods play a vital role in supporting ecosystems within floodplains, wetlands, billabongs, rivers and streams. How beneficial a flood is to the environment can depend on many factors, including the flood size, duration and time of year it occurs . Many plants and animals rely on flooding for their species to prosper.
Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts. Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils.
Another thing we wondered was, how is the environment adapted to flood?
Floods occur naturally. They are part of the water cycle, and the environment is adapted to flooding. Wetlands along river banks, lakes, and estuaries absorb flood waters. Wetland vegetation, such as trees, grasses, and sedges, slow the speed of flood waters and more evenly distribute their energy.
What causes floods?
Flooding along rivers is a natural and inevitable part of life. Some floods occur seasonally when winter or spring rains, coupled with melting snows, fill river basins with too much water, too quickly.
How does flooding affect the environment?
Flooding has a range of impacts on the environment including: wildlife habitats can be destroyed by floodwater contaminated floodwater can pollute rivers and habitats silt and sediment can destroy crops on farms.
Impact of flooding on humans. Flooding has a range of impacts on humans including: people can be injured or killed by flooding; floodwater is often contaminated with sewage, which can lead to illness and affect clean drinking water ; power supplies can be disrupted; businesses can be forced to.
Then, what are the effects of floods?
Some have found that The government should convince communities suffering the consequences of floods every year to relocate permanently. The government should provide support to settle in the new location. Communities should increase cultivation and vegetation practices to improve food security., and more items.
How does flooding affect an ecosystem?
Floods have direct impacts on the organisms that inhabit rivers, displacing or killing freshwater wildlife for example. They also have indirect impacts on ecosystems via changes to the shape and form (geomorphology) of the river.
What are the economic and environmental effects of flooding?
Floods can have devastating consequences and can have effects on the economy, environment, and people. During floods (especially flash floods ), roads, bridges, farms, houses, and automobiles are destroyed. People become homeless.
How does river flow affect ecosystem function?
Variation in river flow (i. e, the river flow regime – see Module 3) exerts a strong influence on river and riparian ecosystem function. In particular, floods and droughts control the creation and maintenance of river and floodplain habitats and the sustainability of the high biodiversity observed along river systems.
