Sediment Shape Evolution Due to Pebble Abrasion in the Rio Mameyes, Puerto Rico

Data collected from the Rio Mameyes to characterize change in size and shape of river sediment due to abrasion.  Complete details on measurement and calculation techniques can be found in the following paper: Qunatifying the significance of abrasion and selective transport on downstream pebble evolution, Journal of Geophysical Review: Earth Surface, (in review).
