Abstract

Fire is a key factor impacting soil hydrology in manyMediterranean catchments. Soilwater repellency (SWR) can
stimulate land degradation processes by reducing the affinity of soil and water thereby triggering a reduction
in soil fertility and increasing soil and water losses. The effects of two consequent fires (1989 and 2005) on
SWR were assessed in the Carmel Mountains, Israel. Fire history, plant recovery and post-fire management (14
treatments)were investigated as determining factors in a time dependent system. In total 210 locationswere investigated
9 times fromOctober 2011 to February 2012,which totals 1890water drop penetration tests thatwere
performed. During each visit to the field (9 times) a soilmoisture contentwas measured for each treatment. SWR
was highest in the N50 years unburnt plots, where soil under Pinus halepensis is most hydrophobic. In the most
disturbed soils (twice burnt), many sites have a low to absent SWR even if the soil is very dry. The dynamics
and fluctuations in SWR differ in magnitude under different plant species. The areas treated with CC (chipping
of charred trees) showed a much higher SWR than areas left untreated. From these insights, a conceptual
model of the reaction of SWR on multiple fires was developed.
