THEORY OF WATER MOVEMENT IN SOILS: 5. UNSTEADY INFILTRATION FROM SPHERICAL CAVITIES.

摘要: AN ANALYTICAL TECHNIQUE FOR THE STUDY OF INFILTRATION FROM MULTIDIMENSIONAL CAVITIES IS PRESENTED. NEAR CAVITY WATER CONTENT CAN BE EXPRESSED AS SUM TWO TERMS. FIRST RESULT ABSORPTION, SECOND DUE TO GRAVITY. SOLUTION REDUCES KNOWN EXPRESSIONS BOTH VERY SHORT AND LONG TIMES PROVIDES A PROPER INTERPOLATION MODERATE TIMES. CASE SPHERICAL TREATED EXPLICITLY ILLUSTRATIVE EXAMPLE. /AUTHOR/
