Land<br />utilization techniques like agriculture, forest and rangelands, residential and urban are among<br />influential criteria affecting erosion severity and sediment yield in a given region. In this respect,<br />land management is a promising option to mitigate it. Thus, acquaintance with quantitative soil<br />erosion owing to land-use changes is of great importance for estimating disadvantages and<br />latent and intangible symptoms of erosion. Strategic planning for sustainable development<br />could be benefited from such knowledge. The current research considered a statistical period<br />from 1970 to 2004. This period was sub-divided into two separate periods from 1970 to 1987<br />and from 1987 to 2004. During these periods, statistics relating to sedimentation, climatology<br />(precipitation) and hydrology were analyzed. Results revealed that the sediment reduction in<br />these two periods under similar rainfall would be as a result of an increase in abandoned areas.
