Resumen
This research indicated that gully erosion can severely
damage croplands in this area of Iran. Significant gully
development occurred in the 3 years of study and the
product of drainage headcut area and slope was more
strongly correlated to gully development than using just
slope or drainage headcut area.

This research indicated that gully erosion can severely
damage croplands in this area of Iran. Significant gully
development occurred in the 3 years of study and the
product of drainage headcut area and slope was more
strongly correlated to gully development than using just
slope or drainage headcut area.
Slope and drainage area indicated an inverse relationship
for initiation and development of gullies The relative area
exponent (b) ranged from 0.46 to 1.2 in this research. Our
results are agree with Desmet et-al’s findings. Results imply
that with these drainage area above headcuts , slopes less
than 2 percent is required for gully development. Therefore,
changing slopes above gullies in this region would be
recommended to mitigate gully erosion. [--]
