Abstract:

The capability of the two-parameter Phiip equation to describe infiltration of water into soils of the semi-arid Sirima and Mukogodo catchments in Laikipia District was investigated. Field measurements of infiltration during dry and wet seasons were taken using a double cylinder infiltrometer on plots under four landuse/vegetation cover treatments within different soil types surveyed at detail level. The four treatments were: (i) tree/bush, (ii) open grass, (iii) bare ground, and (iv) cultivation. The infiltration rates predicted by the Philip equation after 180 minutes in the dry and the wet seasons for Mukogodo and the wet season for Sirima agreed with observed infiltration rates. However, the fit of the equation was inadequate in the early stages of infiltration in both areas and seasons. Equation parameters obtained by best fit of observed data significantly differed between the landuse /vegetation cover treatments and soil types within each area. Only Sirima soils yielded significantly different parameters in-between seasons
