We paid attention to near-surface hydrology which influence the change of groundwater flow characteristic to grasp generally the width of long-term change of the geological environment condition with climatic / sea-level changes, and collected the data of evapotranspiration of 84 districts shown in about 50 parts domestic and foreign documents about evapotranspiration that it was difficult in the data of near-surface hydrology and arranged information about annual evapotranspiration. We collected the data of current Japan and the world district in a high latitude area (an area resemble climate of Japan of the glacial epoch) to consider the width of the change of near-surface hydrology with the climate change because data of the warmness period chilliness period in Japan were necessary. We compiled these information to the table which showed calculation technique or quantity of position / basin characteristic / evapotranspiration / precipitation every district.
