RIVERMorph Features

RIVERMorph® features a state-of-the-art graphical user interface that is user friendly and allows quick access to stored data. RIVERMorph stores river data in a database referenced by river name and reach name. River data is stored under a number of categories, all accessed through the data tree view in the left of the screen. Calculation tools are accessed through the toolbar buttons beneath the tree view. New rivers, reaches and data sets are all added within the data tree view.

Channel Measurement - Cross Section Tool

Cross section data can be entered directly, copied from the Windows Clipboard, or imported from a HEC file. RIVERMorph also provides a screen for entering survey data and performs data reduction for plotting the section. RIVERMorph graphs the cross section data loaded into the current table. Bank-full hydraulic geometry is displayed based on bank-full indicators identified in the survey. A slide tool built into the cross section form allows the user to adjust the bank-full elevation and quickly recalculate bank-full dimensions.

Channel Measurement - Profile Tool

Longitudinal profiles are entered using a similar format to the Cross Section Tool. The graph provides options for smoothing water surface profiles due to data collection errors, and calculates regression lines through data points selected by the user. Average reach, riffle, run, glide and pool slopes are calculated from the graph using a variety of tools and can be stored directly into the database. RIVERMorph also allows the user to quickly measure a variety of geomorphic parameters from the profile graph, such as pool to pool spacing and pool length.

Channel Measurement - Channel Materials Tool

The Channel Materials tool calculates the particle size distribution of bed materials using data based on the Wolman pebble count method or data from sieve analyses. The percentage of various sizes of particles comprising the bed materials is computed and a slider tool can be used to determine the size of particle corresponding to a user defined percent finer. Critical data obtained from the particle size distribution analysis is stored in the RIVERMorph database and can be easily retrieved for stream classification and sediment transport validation calculations. Results from the analysis can be graphed and printed.

Channel Measurement - Stream Classification

RIVERMorph determines stream classification using the Rosgen Classification system. Data for stream classification can be entered directly into RIVERMorph or information stored in the database can be accessed to complete the classification. By checking the reference reach tab in the upper left-hand corner, data from a particular reach can be stored as a reference reach for use with Natural Channel Design.

Pfankuch Channel Stability

The Pfankuch channel stability assessment was developed to rate the relative stability of a channel based on a number of parameters. The user completes the Pfankuch channel stability form included in RIVERMorph and the program calculates an overall Pfankuch rating. Using the Pfankuch rating plus stream classification information an overall reach condition rating is easily determined.

RIVERMorph Additional Information

RIVERMorph includes a variety of other tools which facilitate survey data reduction, development of dimensionless ratios for Natural Channel Design, estimation of bank erodibility, biological assessments, and calculation of peak flows. In addition, tools are available which facilitate the measurement of geomorphic parameters from aerial photography or topographic mapping.
