Abstract

Sediment yield in the San Pedro Lake watershed, inferred from sedimentation in the lake, can be related to land use changes shown on aerial photographs taken during the period 1943-1994. To study effects of these changes, the AA. took a core from the centre of the lake and estimated sedimentation rates by Pb 210 dating, which they checked with Cs 137 and pine pollen. Sediment yield between 1955 and 1994 closely tracks the total land use change that can be detected on sets of aerial photographs. However, this measure of land use change may be unreliable because it probably excludes many changes that occurred in long intervals between successive photographs
