Effects of compaction, moisture and depth on the parameters of the kostiakov equation

This report consisted of studying the effects caused by the soil physical characteristic, in the presence of wetness variations and structures-texture fluctuations, to the Kostiakov constants. The objectives were to investigate the effects of wetness, soil depth, and compaction on the Kostiakov constants “a”, and “b”. The experimental unit consisted of nine polyvinyl cylinders. Statistical analysis under a randomized block design with three replications and three factors: wetness with five levels, soil depth (0-15, 15-30 and 45-60) and compaction with three levels (0, 13 and 26 blows). The relation between the instantaneous infiltration versus compaction and bulk density were inversely proportional. The parameter “a” influenced infiltration more than “b”. Soil texture and structure influenced “b” more than wetness. Wetness influenced “a” more than compaction and soil depth. Kostiakov parameters exposed physical relations to soil texture and structure.
