| Research Abstract |
(1) A field research on damage in agricultural land by sea water invasion was conducted on case of 2004 Indian Ocean Tsunami. A method to predict the damaged area using satellite image and geological information was developed.
(2) The fresh water ponding irrigation method was found most effective for desaliinization of the sea water invaded farm land by a field experiment.
(3) A desalinization characteristics index(DCI) by ponding irrigation was proposed. The validity of the index was confirmed by a column experiment and a numerical simulation.
(4) Water requirement for desalinization was mapped on a studied area using the index.
(5) A scheme for optimum water allocation for desalinization of farm land on coastal area was developed
