2022 FIFA World Cup Stadium in Qatar
Talking about stadiums at Qatar, there are plans to expand the
three already existing stadiums and constructing nine new stadiums for the upcoming World Cup in the
year 2022. Many stadiums in Qatar are of national importance, and guided stadium tours are provided
for tourists. Originally opened in 1976 but renovated in 2005 to adjust more spectators, the Khalifa
International Stadium is the shining image of lavish sporting in Qatar. Also known as the National
Stadium, it is a multi-purpose stadium which includes sports like football, track and field events
and has been a host to the Asian Games, the AFC Asian Cup and many friendlies in football.
The Thani bin Jassim Stadium is another multi-purpose stadium in Qatar, which is mostly used for
football matches, and has been a host to various international matches. Another important stadium is
the Ahmed bin Ali Stadium, which is again multi-purpose and is home to the Al-Rayyan Sports Club.
This venue is set to be totally renovated for the World Cup.
Improving Sub-surface Drainage
Sub-surface drainage can be effective at removing excess water
from the rootzone during high rainfall events and for reducing the water table. These systems assist
in moving water out of the soil profile by providing a pathway for “excessive” or “drainable” water
to leave the soil. They work the best when good surface and internal drainage are in place.
There are a few commonly used systems to help improve sub-surface drainage including pipe drains,
interceptor drains (also known as French drains), trackside drains, strip drains and sand-slit
drains.
