2.Conterits of Survey
(1) Thailand : The Sukhotai plain and the delta of Chaopraya River are characterized with a dry climate. The average precipitation is berween 1300-1800 mm and the rainy season is between June and November. It rains particularly often in September and October, when in places it a water pillar connects the sky with the ground.On the contrary, the dry season lasts six months , from Desember to May, and the humidity during this period, including the periods at the end of the rainy season in May
… More
and beginning in December, is marked to be a mere 100 mm of precipitation. Especially in March and April ; , when the medium sized and smaller rivers expose their river beds, and there is not a single drop of water, the reddishbrown earth strechers from one end to the other and the scattered forests with bare trees appear faded and lifeless. That is why , in order to carry out agricultural work, it was important to save up water during the rainy serson to use it during the dry season. Due to suth at attempt, huge reservoirs weredigged and put into practice.
(2) India : The Indian people costructed a number of large and small artificial lakes, in particicular South Indian people thus adjusting the land and climatic conditions in accordance with their necessities. The stone monements depict the fact, that whenever a temple was built a dam or a water reservoir was also constructed. There are also entries like, "afraid not from the burning heat of the sun, " which make clear the fact, that by gaining control over the energy, notably called "water" . the people of the region stopped to fear the draft and the floods.
Yet, the soil in this part of the world is mostly a mixture of sand and clay, one, which can hardly be called suitable for agriculture, At the times of Pallava Dynasty people constructed surrounding moats, into which they guided a part of the rain and rivers' waterthey broke dams during the rainy sersons, when die volume of the water considerably increased saving the water surplus and using it to cultivate the land. That was their way of life.
(3)Cambodia : l. Geological and petrologic Survey : Dry seasan and rainy season, the surveys concerning geology and petrogy were carried out in the Angkor Area, especIally Baanteay Kdei. Angkor Wat and Angkor Thom etc.and got excelent results. 2. Diagnosis of strong of stones the using the Resonance Method : The Resonance method crystallized Japanese now and high-technology is to disgnosis the strength of deteriorated stone. Based on the resonance tests executed to the pillars situited in the gallery of Preau cruciform of Angkor Wat, the bottom of these pillars come to light an extremely dangerous condition. 3. Survey on the water ground level and the decline of riverbed in Siem Reap river : The actual stale of Siem Reap river and the irrigation system in the Angkor Period were examined in order to compare both of them. In conclution due to the decline of riverbed of Siem Reap river, the water irrigation system.come to be unworkable. Less
