Abstract

Using geospatial data from the mined Tangipahoa River floodplain for 1980 to 2004, the aims of this study are to (1) assess if pit characteristics such as proximity to channel and size affect the potential for diversion; and (2) interpret relationships between pit diversions, channel changes, and floods. Of the 56 pits mapped in the floodplain in 1980, 6 had been captured by 2004. Captured pits were closer to the main channel than those which were not captured, but the areas of captured and noncaptured pits were not significantly different. However, avulsions into large pits caused more channel planform change than those into smaller pits. These results will be useful in understanding landscape vulnerability and can be applied to river management and restoration
