What are floods?
A flood can occur when water overflows and submerges normally dry terrain. Within the sense of "flowing water," the term can even discuss with the tide's inflow.
What causes floods?
Land-use changes like deforestation and destruction of wetlands, changes in river channels or flood barriers like levees, and greater environmental challenges like global activity and water level rise all contribute to increased flooding intensity and frequency. Greater rainfall and extreme weather events caused by the process exacerbate the severity of other causes of flooding, leading to more violent floods and increasedflood risk.
How does floods occur?
Flooding occurs as a result of rainwater accumulating on wetland during a district flood, or as a result of an overflow of water from a water source such as a river, lake, or ocean, where the water overtops or breaks levees, causing the water to leave its usual bounds. While seasonal precipitation patterns and snowmelt may vary the volume of a lake or other body of water, these changes are considerably less likely significant unless they flood property or drown cattle.In addition to property damage, flooding may result in long-term population migration and an increase in the spread of waterborne infections and mosquito-borne diseases.
How does floods impact water quality?
Flooding generates billions of dollars in property damage and poses an enormous threat to water quality. Flooding also destroys water sources and increases the danger of contamination.
Water contamination is split into two groups by experts:
1. Point sources
2. Non-point sources.
1: Point sources are the foremost common explanation for water contamination. Consider a hazardous waste-disposing structure. When a factory like this might be flooded, the water absorbs all the harmful materials. Chemicals flow into underground water, main streams, and other water sources if the water isn't treated.
2: Non-point sources, like leaking fuel on parking lots, plastic trash, fertilizers, and detergents, constitute the second group.Although its visiting not be immediately apparent, pollution poses a hazard to the seas and destroys ecosystems like coral reefs.
What are the steps to be taken?
Aside from the event of essential devices like flood gates, there are a variety of other options for reducing flooding and thereby preventing pollution.
1: Experts recommend that logging must be halted, the forest replanting should begin, and the wetlands should be replenished.
2: The University of Nebraska also offers several steps simple-to-implement options and directions like,
>Gravel, pavement, or stone should be used rather than concrete in areas where flooding is common.
>Compost and green zones, which absorb and decelerate water must modify its flow direction.
>Rainwater collection tanks which is ready to be reused also help to forestall flooding.
There are many other steps that should be taken to minimize flooding and thus minimizing the deterioration of water. When flooding occurs, it takes with it, all the rocks, soil, trash and may be micro-organisms.
