Land reclamation or simply reclamation is the process of making new land from the ocean, lakes, and riverbanks. It is also known as land fill. But, this is not landfills. A landfill is a waste disposal ground, whereas a land fill is a fresh land created from the ocean or riverbeds. The new land formed by the process of reclamation is termed as reclamation ground or land fill.
This process of reclamation is commonly done in coastal areas. Sometimes rivers and lakes are also filled naturally with sand or dirt; developing some new land in this process.
Land reclamation can be done using different methods. The land can be filled with large rocks or cement, or both. Then the place is covered using clay or dirt until it reaches the required height level. This land reclamation process is known as “infilling”, and the materials used for this purpose is known as “infill”. However, this method has a shortfall. The land acquired through this method is highly vulnerable to soil liquefaction at the time of an earthquake. So, there is a danger of using these lands for residential purposes. Another method of reclamation uses draining of water from the underwater lands of a river or lake. The land gained through this process is used for agricultural purpose.
The traditional process of land reclamation is time consuming, and costly. It also requires lots of resources to complete the project. Moreover, the land acquired through this process is not safe in an earthquake prone region. With the advancement of technology, the technology behind the land reclamation process also changes.
