For the kaolinite crust, the flux q gradually increased with the hydraulic gradient i, and reached its peak at different hydraulic gradients ranging from 80 to 100 and ended as a down-ward curve. For consolidated crusts at 70 hydraulic gradient of valid region of Darcy's a law, the q-i relationobtained by being tested at the hydraulic gradients below 70 was expressed as a straight line which had the saturated hydraulic conductivity of k=6.80 × 10^<-5>cm/s. For the red soil crust, all experimental data points of q and i were approximately on a straight line at the hydraulic gradients below 30, and thus k=2.50 × 10^<-4>cm/s was given.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3627"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
