Resumen
This research demonstrated that the I.R. region is prone
to gully erosion. The study area had limited gully erosion
four decades ago. With accelerating urban development
during the past, two to three decades, areas of gully erosion
increased. Comparison of gully advancement showed that
the area of gully erosion increased 4 times in four decades
before. Gullies are located around urban areas with ...

This research demonstrated that the I.R. region is prone
to gully erosion. The study area had limited gully erosion
four decades ago. With accelerating urban development
during the past, two to three decades, areas of gully erosion
increased. Comparison of gully advancement showed that
the area of gully erosion increased 4 times in four decades
before. Gullies are located around urban areas with more
deteriorated cropland and roads. Statistical analysis
revealed that area of gully erosion could be attributed to the
area of bareland and road length. The overall the impact of
bareland area is more significant than road length in study
watersheds, although their contribution in individual site is
completely different. [--]
