Abstract
This study investigates the relations between watershed precipitation upstream channel slope and the geomorphology of 19 small 40 to 18658 m2 fluvialincised lagoons in the actively uplifting piedmont near Santa Barbara CA Lagoons in the study are funnelshaped shallow 2 m riverdominated and enclosed by a sandy to cobblesized beach barrier for much of the year Results indicate a strong link between watershed processes and lagoon geomorphology such that a significant portion of the variability in lagoon area length volume average width circularity and lagoon width expansion can be explained by the variability of watershed precipitation and channel slope upstream of the lagoons Performing multiple regression analysis with watershed precipitation and channel slope as independent variables coefficients of determination for the power function regressions are 088 lagoon area 088 lagoon volume 083 lagoon volume and 074 average width Upstream slope is the best single predictor of lagoon geomorphology
