Sediment transport by burrowing mammals, Marin County, California

Sediment transport by burrowing mammals, Marin County, California Field observations suggest that burrowing activity is the primary mode of sediment transport currently active in a small grassland drainage basin in Marin County, California. Spatial concentrations of the 1150 gopher mounds surveyed vary from 0‐16 mounds m−2 on interfluves to 0.32 mounds m−2 on sideslopes and in the topographic hollow, with localized concentrations of up to 2.88 mounds m−2 on the margins of the colluvial deposit. Simple models of sediment transport by burrowing activity yield estimates of between 0.91 and 2.33 cm3 cm−1 yr−1 for the basin as a whole, with absolute minimum and maximum rates of 0.48 and 631 cm3 cm−1 yr−1. These values are similar to those previously estimated for this area (Lehre, 1982) and are nearly an order‐of‐magnitude less than average long‐term sediment transport rates at the same site (Reneau, 1988). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Earth Surface Processes and Landforms Wiley

Abstract

Field observations suggest that burrowing activity is the primary mode of sediment transport currently active in a small grassland drainage basin in Marin County, California. Spatial concentrations of the 1150 gopher mounds surveyed vary from 0‐16 mounds m−2 on interfluves to 0.32 mounds m−2 on sideslopes and in the topographic hollow, with localized concentrations of up to 2.88 mounds m−2 on the margins of the colluvial deposit. Simple models of sediment transport by burrowing activity yield estimates of between 0.91 and 2.33 cm3 cm−1 yr−1 for the basin as a whole, with absolute minimum and maximum rates of 0.48 and 631 cm3 cm−1 yr−1. These values are similar to those previously estimated for this area (Lehre, 1982) and are nearly an order‐of‐magnitude less than average long‐term sediment transport rates at the same site (Reneau, 1988).
