Leith Flood Protection

The site chosen for this report is the Moolap Waterfront and its hinterland. It is located 5km East of the City Centre of Geelong, South -west of Melbourne, Victoria. The site is generally flat topography with a significant coastal frontage and it’s considered to be a flood prone area.(This should go up)

Government intervention is need when there has been a market failure due to a misallocation of resources. The government intervention is imposed to try and fix the negative externalities produced from the consumption or production of a good or service. In this case the market failure is resulting from the felling of trees for farming and wood purposes. The flood defences are a public good which is a good that is non excludable good and non-rival good.

Located at the mouth of the Teign estuary, Teignmouth is one of the most important coastal towns along the English Channel. Such a geographical location of Teignmouth has made itself at the forefront of the powerful sea waves and winds from the ocean and exposed to the risks of flooding and the damages of shoreline erosion due to the long-term hitting of the strong sea waves. In its early history, such coastal protection and defense systems as sea walls had been built and then toppled down by the strong sea wave and wind. The Teignmouth coastal engineering scheme is a series of recent coastal protection efforts to protect Teignmouth from the menace of the flooding and erosion.

This policy is applied where areas where a high risk is applicable to many people due to environmental changes or social implementations to put in sustainability phase watching technical viability and economic justification.

One major factor to consider regarding future development in Andrews is its potential to flood, since landowners in higher risk areas for flooding would have to purchase flood insurance and prepare for a flood. Since a catastrophic flood event could destroy properties and infrastructure, as well as hurt the local economy, there are areas known as Special Flood Hazard Areas,

Most of the catchments depicted in Figure 1 where fully urbanised which caused surfaces in the catchment to be impervious; that is very little runoff would infiltrate into the ground

The density independent factor of the floodplain would be that flooding can occur. The reason it is density independent is because flooding is an abiotic factor that is unable to be controlled. After the flooding is complete and the willow brush grows in size and quantity, this also is an example of recruitment. As the species of willow grew, the carrying capacity also increased. This proves that the ecosystem based on the floodplain is resilient or unable to be affected by the flooding. As this location gained biomass from the increase in carrying capacity, the biodiversity of the riparian vegetation also

Increased surface water flooding in low lying areas or heavy rainfall may overcome the capacity of the drainage system. There can also be damage to coastline structures due to storm surge, flooding and salt water intrusion.

The focus of the flooding during Storm Desmond was in northern England, particularly Cumbria, causing large scale flooding to an area witnessing similar scenes in 2005 and 2009. The flood defence wall in Keswick, constructed following the 2009 flooding, was overtopped on the 5th (Plate 4), inundating business properties20 and 730 residential.

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.

During the Autumn/Winter of 2013/14, an unusually high frequency of depressions moved across the Somerset Levels, causing both fluvial and pluvial flooding on a prodigious scale. The two main rivers which flow through the Levels (River Tone/Parrett), burst their banks, spilling into the already heavily saturated flood plain. An emergency was declared and subsequently allowed the Somerset council to request financial and physical aid to the region. This essay highlights the key reasons the Somerset Levels flooded, as well evaluating the main management solutions that were put forward during the peak of the flooding.

The purpose of this report is to geologically evaluate the potential hazards for flooding in Hazard City. This report will include a detailed historic and extrapolated Stream Gauge Data Worksheet, as well as a graph of the Discharge Frequency Curve expected on Clearwater River. The report will provide Hazard city with my scientific analysis, conclusions, and provide recommendations concerning potential flood damages.

On the other hand sea walls are one of the most expensive forms of sea defence. A good example of this is the relatively recent process that Pevensey Bay has been through. Pevensey bay is a small sea side village resort with large number of properties directly on the beach. Furthermore, It is not just this community that is at risk. It was stated that “A permanent breach in the [beach] would result in a 50 square kilometre area behind the defences flooding at high tide. Over 10,000 properties, several caravan parks, important road and rail links would be affected, as would Pevensey Levels, an important ecological site that has Ramsar Convention status as a Wetland of International Importance.“(“PCDL - Pevensey Coastal Defence Ltd,” n.d.). This shows that this is indeed a high value site, one that requires an advanced and effective defence system.

Dams built for flood control and water catchment along the rivers leading to these coasts inhibit the transport of large grained

Flood control is a public good that helps to prevent flooding which, benefits the community, but can cause market failure.
