Figures
- Figure 1
Conceptual diagram of modeling approach to estimate severely eroding streambanks using LiDAR. The drawing shows a cross section of a streambank with the bank angle calculation.

- Figure 3
Location of streambank soil samples collected from stream order sites located in a range of landscape regions in Iowa.
- Figure 4
Location of severely eroding streambank lengths in third- to sixth-order streams and rivers of Iowa.
- Figure 5
Frequency distribution of 145 streambank soil total phosphorus (TP) concentrations.
- Figure 6
Mean annual total phosphorus (TP) yields exported from 16 watersheds draining to the Mississippi and Missouri rivers (modified from Schilling et al. 2020).
Tables
- Table 1
Summary of annual streambank recession rates measured using erosion pins at various Iowa sites.
- Table 2
Variations in estimated annual total phosphorus (TP) export from Iowa streambanks using standard assumptions (equation 1) and likely low and high range values of parameters.
- Table 3
Annual riverine export of total phosphorus (TP) in Iowa and the estimated annual contribution from streambanks. Note that the annual streambank export is a constant (from equation 1).
