Question

flooding of low lying areas aim or objectives​

Answer 1

Explanation:

The primary objective of the study was to develop a sustainable coastal defence scheme for managing coastal erosion and flooding risks along the Eastoke Point frontage.

This coastline has a long-term history of retreat as a result of rising sea levels, variations in the wave climate and changes in the position and alignment of both the deep channel through the entrance to Chichester Harbour and the banks of the ebb shoal delta that form on either side of that channel. This study includes a review of all these effects as an essential background to the consideration of the future management of the Eastoke Point coastline.

The overall coastal defence policy for this frontage was established in 1996 in the East Solent Shoreline Management Plan and reconfirmed during the North Solent SMP in 2010 as “Hold the Line”. Subsequently, in 2006, a detailed Coastal Defence Strategy Study for the whole Eastoke peninsula (The Eastoke Sectoral Strategy Study) was carried out and considered some options for suitable coastal defence schemes for Eastoke Point that would provide an adequate standard of protection to these low-lying residential areas. The Eastoke Sectoral Strategy Study supported the Hold the Line policy for the frontage and recommended that the defences are improved to give a standard of protection of 0.5%, i.e. protecting the assets at risk from storm events with a return period of 200 years.

Flood and Erosion Risks

In 1992 a breach occurred in the defences around Eastoke Point and emergency works were undertaken. These works involved the construction of 150 metres of rock revetment and rock stub groynes. At present, beach levels along much of the southern coastline of the Eastoke peninsula are being managed to provide an adequate standard of defence against coastal flooding and erosion. In addition, defences have recently been improved along the northern shoreline of the peninsula, reducing risk of tidal inundation from that coastline. Around Eastoke Point, however, the present standard of protection against coastal flooding and erosion is considered to be low.

Answer 2

Flood refers to a state of natural calamities that happens due to the overflow of water.

EXPLANATION-

This overflow of water can be due to heavy rainfall, Dam realizing water, Cyclone-Tsumani, Ice melting due to Global warming and other reasons. Flood is a result of the distribution in the ecological balance of the environment that leads to the destruction through the water.

As another natural calamity, the flood also causes a disruption at a large scale to human life and assets.

Causes that lead to more loss through floods -

• Soil erosions - Soil has an excellent capacity to hold water but due to soil erosion. In the times of flood soil retention power to hold of natural vegetation becomes weak which leads to more losses of natural vegetation.

• Disruption of assets - Flood causes a loss of assets of both kinds natural or man-made. Due to heavy rainfall and diverted flow of water, the areas that are not pronto flood impacts also get affected in a large space.

Conclusion-

Hence, these are the main reason or areas that get affected mainly due to the flood occurrence.
