Land Reclamation
INTRODUCTION
Land reclamation means the modification of inadequate land area, by leveling, draining, etc., so as to permit man to use that land. The practice of land reclamation has changed since the 1940's, because of increasing demand for industrial, residential, and recreational land near urban centers. Prior to the last two decades, land reclamation embodied land drainage, flood protection and prevention, and irrigation primarily to further agriculture. Today, floodplains, swamps, abandoned mineral workings, and geologic hazard areas are modified to meet man's increased demands for more intensive uses.
Land Reclamation and Types
The process by which seriously disturbed land surfaces are stabilized against the hazards of water and wind is called land reclamation. It is either of two distinct practices – ➢ Creating new land from sea or riverbeds ➢ Restoring an area to a more natural state

HISTORY OF LAND RECLAMATION
✓ The first known land reclamation work was done by themayans,some 1500 years back for agricultural purpose. ✓ The 18th century the Dutch succeeded to device a modern way of land reclamation from North Sea. ✓ In last few decades numerous land reclamation projects have been undertaken in various countries. ✓ In recent Dubai and Nederland have undertaken some huge land reclamation projects.
RECLAMATION TECHNIQUES
1. Through the use of the drain large area can be efficiently reclaimed as drainage helps to firm and settle of land
2. Protection of flood plain by the construction of dams, dikes and levees and channel improvements.
3. In areas of landslide active slope reclamation consist of tree and shrub plantings.
