What effects does the River Severn flooding have on physical factors such as wildlife?
The flooding of the 350 km long river Severn in the summer of 2007 induced a number of physical impacts to natural flora and fauna species.
Macro-invertebrates like worms and beetles living in the soils may have died or been forced to migrate, which affects the prey of other fauna species (food-chain disruption).
Also Morphological changes in a rivers channel due to high velocity river discharge (river Severn 22m/s) enables it to cut through meanders or even destroy natural or manmade levees.
Also floods can cause contamination of water supplies through a process called Eutrophication, by which surface runoff from urban areas carries waste and chemicals (domestic and/or fertilizers and pesticides) which can enter the river as it recedes. This has the potential to cause algae blooms which starve the river of oxygen threatening the natural ecosystem.
However there are some positive impacts in that although soils may be eroded in flood events, sediment left when the river recedes creates natural levees on floodplains.

What effects causes flooding?
Flooding can be caused by heavy rainfall, snowmelt, storm surges, or dam failures. Other factors such as deforestation, urbanization, and climate change can exacerbate flooding by altering natural drainage patterns and increasing the likelihood of extreme weather events. Improper land use practices and inadequate infrastructure also contribute to flooding.
What factors limit the potential production of wildlife?
There are many factors that limit the potential production of wildlife. One of these factors is the loss of habitat.
What are the main factors that contribute to basement flooding?
The main factors that contribute to basement flooding include heavy rainfall, poor drainage systems, cracks in the foundation, and improper grading of the land around the house. These factors can lead to water seepage and accumulation in the basement, causing flooding.

What factors contribute to flooding?
the rain factors in flooding because there is to much rain overflowing from any rivers nearby, or it has no way of getting out of where it fell, like in a valley or something.
What is meaning of wildlife depletion?
Wildlife depletion refers to the declining population and loss of various species of plants and animals in a specific geographic area. This can be caused by factors such as habitat destruction, pollution, climate change, poaching, and overexploitation of resources. Wildlife depletion can disrupt ecosystems and lead to cascading effects on biodiversity and the environment.
What are the physical and human factors of tourism?
Physical factors of tourism include natural attractions like beaches, mountains, and wildlife, as well as climate and geographical features. Human factors include accessibility, infrastructure, cultural heritage, hospitality services, and safety and security measures in the destination. Both physical and human factors play a crucial role in attracting tourists and ensuring a positive tourism experience.
What are factors which affect wildlife?
Factors that affect wildlife are the same that affect our ability to live, food, space, shelter, reproductive recruitment, predation, disease, and other mortality issues.
How does constant lightning affect the ecosystem and wildlife in the affected areas?
Constant lightning can have both positive and negative effects on ecosystems and wildlife in affected areas. On one hand, lightning can cause wildfires that can disrupt habitats and threaten wildlife. On the other hand, lightning can also help to replenish nutrients in the soil and promote new growth in ecosystems. Overall, the impact of constant lightning on ecosystems and wildlife depends on various factors such as the frequency and intensity of the lightning strikes.
What are the contributing factors to stress reactions is the physical factor?
Physical factors such as illness, fatigue, poor diet, and lack of exercise can contribute to stress reactions by weakening the body's ability to cope with stress. When the body is already physically compromised, it is more vulnerable to the effects of stress hormones and may struggle to recover from the physical toll of stressful situations.
What causes changes in muscle tone?
Changes in muscle tone can be caused by factors such as physical activity, stress, neurological conditions, and medication side effects. These factors can affect the level of tension in muscles, leading to variations in muscle tone.
