| 内容記述 | Recently, regional evaluation of disaster-prevention and maintenance indices in rice terrace can be easily done, because refined database of farmland polygon have been constructed in each prefecture and refined map such as GSI basic geographic data can be utilized by usual engineers in Japan. As first step, outline of process in evaluation of regional indices is shown, using farmland polygon data and GSI basic geographic data. At the second step, disaster-prevention maps are presented for typical sites of steepland in hilly area, and result of comparison between evaluated indices and field observation at sites. These maps are seems to be useful by evaluating indices about both inflow and outflow from the ground surface, which is obtained by performing numerical analysis of seepage flow in shallow ground. Indices can be evaluated for rice terrace of various soil type using potential gradient of seepage water. Necessity of levee weeding and ‘shirokaki, azenuri’ （plowing for planting young rice, levee mending for seepage control） can be numerically visualized in above mentioned mapping procedure. At the last step, the results of comparison between maps based on proposed indices and conventional ones are given. It is clear that proposed indices based on potential gradient indices can give appropriate results, otherwise conventional indices based on seepage velocity shows sometimes give inadequate results. |
