On Monday, Thai Prime Minister Yingluck Shinawatra ordered canal dredging and reinforcement of flood-prevention
embankments to protect the city, state-run news agency MCOT reported. In addition, three new flood-prevention walls
were being built at two locations in Rangsit, in northern Bangkok, and in Taling Chan, in the western part of the city.

The government needs another 1.5 million sandbags, MCOT reported. The prime minister called on the private sector to
supply them, but said the government will buy all the needed sandbags by Wednesday, the news agency said.
Meanwhile, around 1,200 people have taken shelter in a gymnasium at Bangkok's Thammasat University. Most of them
are from neighboring Ayutthaya province and other flood-affected areas around the capital, said Thanawat Srisuwan, a
volunteer at the makeshift shelter.
The authorities have set up almost 200 other temporary shelters around the city to receive flood victims. The Bangkok
Metropolitan Administration said plans were in place to evacuate people from nine areas, mainly in eastern Bangkok, if
needed.
Elsewhere, patients in two hospitals in Thailand's Ayutthaya and Nakhon Sawan provinces had to be evacuated after
water reached the first floor, the flood operations command said.
Multiple tropical weather systems have moved over the region in recent weeks, enhancing monsoon rains and leading to
the flooding. Another low pressure system is forecast to move into Southeast Asia on Tuesday and Wednesday, said
Brandon Miller, senior meteorologist for CNN International.
According to the government website Thaiflood.com, water from northern Thailand has finally reached lower parts of
central Thailand, penetrating dykes in Pathumthani and Nonthaburi provinces and flooding outer areas of Bangkok,
including the market in Nonthaburi and Chiang Rang road.

Construct state of a concept
Use SPARQL to query some knowledge evolution from
the UCK and UCCK with conditions
input concept, input time, and input community.
Use Jena rules to transform selected knowledge evolution to list of triple.
