Water is essential to survive, if there would be a lack of drinking water, people may have various health-related issues such as dehydration. According to these climate forecasts, the future of fresh water will be full of extremes: Droughts will pose serious challenges to the safety, health, food and water supplies of plants, animals and humans in some regions, and floods will do the same in others. Its clear that large-scale flooding has become more frequent and severe. Drought caused by El Nio. The heaviest storm probably occurred in 1832 with maximum recorded . Trees act like a sponge that helps to hold soil and water and prevent flooding. China, for example, has been investing heavily in sponge city concepts, the development of which could potentially help control and mitigate flooding, and recycle rainwater resources and re-instate degraded environments at the same time. These calamities were majorly due to natural reasons but nowadays we can see an increase in flood and drought due to human interference. It might last for weeks, months, or years and may have many negative effects. Landscapes and crops need more water to survive and overall the demand for water increases. An official website of the United States government. Sea water levels have been recorded to, Dam failures and breakage can also send a powerful and destructive surge of water downstream. A flood is an overflow of water onto land that is normally dry. What are the main causes of droughts and floods? We can use several methods to prevent flooding: Increase spending on flood defences, here the focus should be on flood resilience rather than defence schemes. Flash floods can roll boulders, tear out trees, destroy buildings and bridges, and scour out new channels. When this icecap melts in the summer season, it results in huge releases of water into the places that are usually dry. Natural disasters are catastrophic events with atmospheric, geological, and hydrological origins (e.g., droughts, earthquakes, floods, hurricanes, landslides) that can cause fatalities, property damage and social environmental disruption [1].. What are the 3 effects of disaster? What are the main causes of droughts and floods? Drought can occur in any region of the world.

Really hot temperatures can make a drought worse, Major Causes of the Drought High Temperatures. Flooding, especially flash floods, can devastate entire cities and urban environments. A managed retreat, which can occur over time and allow systems that account for migrants and displaced people to be in place, can be less traumatic for people and potentially less expensive in the long run. Additionally, Deforestation also leads to droughts in some areas. Construct buildings above sea level so that these buildings do not submerge in moderate rain. Before we examine the causes and effects of floods, its important to note there are various types of floods that can occur around the world. Links to additional maps and drought data are listed on the USGS Drought website and the National Integrated Drought Information System (NIDIS). Deforestation: Deforestation is one of the major human causes of floods. This of course begs the inquiry How can a drought cause a flash flood?. What are the main causes of droughts and floods? Over-abstraction: taking too much water from water stores (reservoirs, rivers and aquifers) These can be linked with wider geographical processes. There are natural causes as well as human causes of drought. A flood can trigger breeding events and migration. When rainfall in low-lying areas and urban environments fall faster than the ground can absorb, water height rapidly rise, resulting in floods. When little or no rain falls, soils can dry out and plants can die. Irresponsible agricultural practices like the over-irrigation (depleting water resources) and over-farming (adversely impacting the soil quality) of land can often lead to droughts. When there is an outflow of water in a place, it is said to be flooded. Flash floods tend to be more common in areas with a dry climate and rocky terrain due to lack of soil or vegetation, which acts as a defence or barrier against torrential rains flowing overland. One of the biggest consequences and effects of floods is that people lose their home and property, and essential buildings and infrastructures such as hospitals and elderly homes are left incapacitated. Roads can become like rivers and if there is a lot of water, it can flood buildings and carry cars away . Climate change, environmental degradation, population growth, urbanization and augmenting poverty cause human society to be more vulnerable to flood and drought disasters. what are the main causes of drought and floods.

Atmospheric conditions such as climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape are all factors that contribute . Leakages need to be amended. The first evidence of drought is usually seen in records of rainfall. This leads to potential long-term social inequalities and unrest. The UN's World Meteorological Organisation warned last November that the current El Nio is the strongest in more than 15 years and will cause severe droughts and devastating flooding throughout the tropics and sub-tropical zones of the planet. Answered By. 1) Land and water temperatures cause drought. The failure of the EA long rains is the main cause of the droughts, as a result of climate variabilities and anthropogenic impacts. Droughts can range from short-term and localised precipitation deficits to longer-term trends that are part of climate change. Explain how humans have an impact on the hydrological cycle. Here is a list of the factors that trigger a drought: Little or no precipitation is one of the major causes of a drought. Lower than average El Nio. A drought is a period of drier-than-normal conditions that results in water-related problems. Since humidity levels are more, or droughts are common in areas experiencing long, dry seasons are a few additional things to keep in mind. Water transportation channels need to be maintained properly. No food reserves. and some parts of southern Africa: i) the 1950s-60s and after the 1980s-90s, when floods (droughts) tend to be more (less) intense .
