  • The hydraulics of composite overland flow around surface stones are extremely complex and have been little studied. The purpose of this paper is to review both field and laboratory research on this subject and to discuss briefly the implications
  • density, porosity and water content. Hydraulic properties that affect infiltration are water retention, saturated conductivity and unsaturated conductivity. Rock fragments on the soil surface have been reported to both increase or decrease infiltration
  • computerized and automatic techniques. This study makes possible a comparison of both methods which appear complementary.
  • Rainfall simulation experiments were carried out on several plots at different times since the fire near Haifa, Israel. The results obtained show that the total runoff and sediment yield varied considerably in both space and time. High spatial
