Evaluated potential damages of future climate change impact of flooding risk by empirical method based and relies on statistical relationships between historical precipitation and flood damage. Changes in precipitation determined by general circulation models (GCMs). Future precipitation daily precipitation totals scenarios generated from an ensemble of GCMs, monthly average change output through SimCLIM (Randall et al., 2007) To evaluate potential damages of flooding by the statistical methods, relationship between observed precipitation and flood damages, these relationships to estimate future damages under a changing climate.
Increases in projected precipitation result of significant increases in damages. Projected in monetary

There are a number of adaptation options that could be considered in order to reduce the risk of flooding to infrastructure in Greater Manchester, now and in the future.
Options to address fooding risk reduction under future climate change
Adaptation measures for flood risk reduction under future climate change
One of the three components of the risk formula, namely hazard, exposure and vulnerability
Increase of flood protection levels
It aims at reducing the vulnerability of people and assets to extreme stream flow conditions. It requires limited space as it normally consists of elevating the river banks, through permanent or temporary barriers, to increase the maximum stream flow that the watercourse can fully contain and convey downstream without causing damage (Lorenzo ET AL., 2016).This keeps the flood storage to minimulevels, hence thehe magnitude of the flood peak can remain unchanged for long river reaches.
Reduction of the peak flows
This adaptation option aims at reducing the flood hazard through a reduction and a delaying of peak flows during extreme events. Peak reduction is achieved by setting up areas within aside the river network that can be flooded in a controlled manner when the river stage reaches critical levels. In addition, peak flows are reduced by
This is will difficult if there housing is severely reduced in value due to the risk that are there of flood. Therefore to increase profits and chances of breaking even, they should provide the initial flood defences for the housing. This will increase the saleability of the housing and profitability of the firms. It also provides social benefit for those that are buying the housing. Yet you could say that the cause of the flooding is not directly the housing estates firms fault and should not have to pay for the provision.
The policy applies to reduce to zero the minimum potential social and economic impacts whereas evading potentially substantial environmental effects. Floodplain connectivity
During the spring and early summers of 2011 and 2014, the Assiniboine River Basin (ARB) in Southern Saskatchewan and Manitoba experienced extreme flood conditions with prolonged duration and severity. This persistence and shortened interval between disasters caused concerns about the impacts of climate change in the region (Brimelow, 2015). The interactions between the Atmosphere, Geosphere, Hydrosphere, and lastly Biosphere all contributed to the events that took place during the specified flood years. I will look to address the intertwined relationship between these four spheres, and conclude with possible mitigation strategies that provinces and municipalities are likely to invest in as anthropogenic change is inevitably shortening the
These scientists have put together information and implemented many measures and replacement strategies. (Davis-Wheeler, N.D.). River diversion is one idea that they implemented for restoring our wetlands. This is done by pumping river water into decaying marshes, increasing the sediment load and reducing the salinity. There are many of these structures currently in use now and more are coming.
In January 2011, the Queensland town of Toowoomba experienced flash flooding leading to the death of several people and large damage. The flood waters surged through the city centre as an “inland tsunami”. Describe the cause and developments of the flash flooding event and critically review Toowoomba’s urban hydraulic structures at the time of the flood event. Use a maximum of 400 words for your answer (excluding Figures) (3 marks)
Information that was used to develop my conclusions were relative to the history of Clearwater River such as the average normal discharge of 40,000cfs, the fact that the river can accommodate 55,000cfs before flooding will occur, and that with every increase of 2600cfs the river rises one foot. For example, this information helped to determine that four of the thirteen noted Peak Flood Discharges listed on the worksheet were not at flood stage as the river is able to accommodate discharges less than 55,000cfs. However, nine of the thirteen Peak Flood Discharges listed on the worksheet were at flood stage or drastically above; with the maximum rise of 17.77 feet above and a discharge rate of 101,200cfs. The average discharge rate of the top three noted floods per information on the Stream Gauge Data of Peak Flow Discharges is 93,613cfs, which is resourceful later in determining the extrapolated 75-year flood.
Climate change was blamed for risen in temperature by half a degree, producing more vapor which results in heavy rainfall in 2010 in Brisbane. The Burnett River and Fitzroy River were exceedingly bad hit on 28th and 29th December 2010, when the stream level rose to more than eighteen meters. Author was discussed that flooding proceeded into January 2011, turning out to be more terrible in Brisbane and damages came around 2.38 billion AUS dollars. Flood again hit the area in 2013 (Davies 2013).
Flooding is a natural cause that happens when too much rain water overflows rivers and marshes, but floods become a problem when they affect people who live around the area. This is what causes it to be a natural disaster. In this paper, I am going to talk first about the flooding in Somerset, UK. Second, I am going to talk about the flooding of the Mississippi in 1993. Finally, I will conclude with how both of these floods could have been prevented and how they could help prevent a flood in the future, along with my own opinion of what I have learned.
The relevance is given as we need an adequate material to build the dam as well as enough water to achieve a water level and finally to maintain that level. It also should be thought about a solution for the silt coming down the river in order to keep on getting a clear flush.
This image highlights that some regions in Sydney were suffering the flooding after the low pressure system swept down the east coast, Queensland, NSW, the ACT and Tasmania. Also the heavy raining and pale force wind leads numerous trees came down over the roads in Sydney. This circumstance has long-term impacts to the environment and the agriculture. Flooding in key agricultural production areas can lead to widespread damage to crops and fencing and loss of livestock. However, flooding has both negative and positive impacts. Positive impact is to increase fish production and recharge ground water. The negative impacts flooding leads too much sediment and nutrient, destroy habitat and impact the water
Predicting that a flooding actually happens in the near future, there’s little to no possibility that’d we survive because it’s not affordable. Living in a capitalist society has led to homelessness and poverty. People aren’t able to afford their everyday needs, and if they do it’s the minimum. Simply because the government chooses who they want to help, people heavily rely on programs like welfare, food stamps etc as a financial aid throughout their whole lives. People are depending on programs like these which are only meant for a period of time but eventually becomes a necessity to get by because struggling to survive is became normal. Things that are needed to survive like affordable housing, food, clothing and education have become
Zimmerman believes that lower elevation facilities and buildings are at a high risk of flooding, and the infrastructure’s risk increases annually due to climate change. Already, one can infer that a stronger storm would contribute to flooding.
The flood-plain management is a planning and action to establish, implement and keep track of plans for the wellbeing of the public. There are eight steps to this program which include: flood hazard recognition, forecasting and warnings, emergency measures, additional or necessary adjustments in structures, flood-plain regulations, planning for land use, flood control, and maintenance of the program.
In no more than 300 words describe the overall strategy of flood protection across the Water of Leith protection scheme. Your answer should consider how the structures at different locations relate to an overall perspective of managing flow.
Scenario analysis explores trajectories of change that diverge from present conditions, ultimately leading to alternative possible future states or events. In so doing, it provides a dynamic and flexible way to evaluate policy or management options. Scenarios are not predictions or forecasts; but rather, they are ‘‘plausible and often simplified descriptions of how the future may develop based on a coherent and internally consistent set of assumptions about driving forces and key relationships’’ (Houghton et al. 2001:796). Scenario analysis enables an exploration of the potential impacts, risks, benefits, and management opportunities stemming from a variety of plausible future conditions. When used in conjunction with modeling, scenario analysis can help bridge the gap between science and decision making, throwing light on how land use changes will affect hydrologic services across a range of spatial and temporal scales and allowing decision makers to effectively prepare for such changes (Liu et al. 2008a, b, Mahmoud et al. 2009).
