Simulasi Numerik Gerakan Lengas Tak Jenuh Dalam Tanah Pada Sistem Irigasi Tetes (Numerically Simulated Unsaturated Moisture Movement In The Soil Of Drip System)
The soil of coastal plain is characterized by sandy soil texture, salinity problem, low water capacity, high percolation rate and high soil temperature during day time. Due to those constraints, therefore much water is needed to be favorable to plant growth. Objective of the research is dealing with...

| description | The soil of coastal plain is characterized by sandy soil texture, salinity problem, low water capacity, high percolation rate and high soil temperature during day time. Due to those constraints, therefore much water is needed to be favorable to plant growth. Objective of the research is dealing with the application of numerical method to simulate heat and mass flow of water which is affected by soil moisture availability. A core of soil sample with size 50 cm x 50 cm x 50 cm is used as a physical model. The research has been scheduled from 1997 to 1998. Under high initial moisture content the simulation shows that there is similarity between predicted and observed value of soil moisture content with the correlation value more than 90% (1-test value 95%). However, the simulation is under estimate for low initial moisture content and high temperature. For the model applications, the factor's which influence on moisture movement in the soil was collected and rearranged in exponential equation:
