Architectural Design Elements For Precautions
Stilt houses Stilt houses in India are the kind
of houses built on flood-prone terrain. In flood
prone areas, houses should be built on a raised
column or plinth beam foundation. The space below
the house should be left open to facilitate the
natural flow of water. Low weight houses can be
built on concrete pillars on moderate budget.
Besides, houses built this way cold withstand
earthquakes and floods.
What type of foundation is best for a flood
zone? If the home is located in an area of
coastal flooding, an open foundation is the only
way to safely elevate the home. If the home is
subjected to high-velocity riverine floodwaters,
significant water depth, or potential erosions,
the home should also be elevated on an open
foundation.

Architectural Design Elements For Precautions
What structures are built to prevent
flooding? Dikes, spurs, levees, and
seawalls often act as the first line of defense
against overflowing rivers, floods, storm surges,
andin the longer termrising seas.
But flood control structures do not completely
eliminate risk. Flooding may occur if the design
water levels are exceeded. If poorly designed,
constructed, operated or maintained, these
structures can increase risk by providing a false
sense of security and encouraging settlements or
economic activity in hazard-prone areas

• A dike or dyke, is a sheet of rock that is formed
  in a fracture of a pre-existing rock body. Dikes
  can be either magmatic or sedimentary in origin.
• Long Spurs, also referred to as groynes, are used
  to direct the course of the river away from a
  vulnerable bank. 
• A levee is a natural or artificial wall that
  blocks water from going where we don't want it to
  go.
• A seawall is a structure made of concrete,
  masonry or sheet piles. It is built parallel to
  the shore at the transition between the beach and
  the mainland or dune, to protect the inland area
  against wave action and prevent coastal erosion.
