BAGS: Bedload Assessment in Gravel-bedded Streams

BAGS is a spreadsheet-based program that predicts bed load transport using six well-known bed load transport equations developed specifically for gravel-bed rivers. Sediment transport estimates are calculated on the basis of field measurements of channel geometry, reach-average slope, and bed material grain size. Field data and other relevant input parameters are entered into the program sequentially through a series of prompts to the user. Calculations are carried out using Visual Basic for Applications and the output is stored on individual spreadsheets.

A companion sediment transport primer is available here. (1440 kb / 84 pages)

WinXSPRO: A Channel Cross-Section Analyzer

WinXSPRO is an interactive Windows™ software package designed to analyze stream channel cross section data for geometric, hydraulic, and sediment transport parameters. WinXSPRO was specifically developed for use in high-gradient streams (gradient > 0.01) and supports four alternative resistance equations for computing boundary roughness and resistance to flow. Cross section input data may be from standard cross section surveys using a rod and level or sag-tape procedures.

FishXing: Software and Learning Systems for Fish Passage through Culverts

Pronounced "Fish Crossing", this software is intended to assist engineers, hydrologists, and fish biologists in the evaluation and design of culverts for fish passage.

Aquarius developed by RMRS.

Aquarius is a state-of-the-art computer model devoted to the temporal and spatial allocation of water among competing uses in a river basin.

Size-Class Pebble Count Analyzer UPDATED VERSION
File: Size-Class Pebble Count Analyzer V1 2001.xls (651 KB) (updated 9/29/2007)
by John Potyondy and Kristin Bunte

This Excel 2000 spreadsheet was developed to assist with the analysis of pebble count data tallied by size class. The spreadsheet helps users estimate sample size, enter field data tallied by size class, produce tables and graphs, and perform statistical analysis using contingency tables and the Pearson chi-squared statistic. After downloading, to execute the spreadsheet users must select "Enable Macros" for the spreadsheet to function properly.

Zig-Zag Pebble Count Analyzer

by Greg Bevenger and Rudy King

This Excel 2000 spreadsheet was developed to assist with the analysis of pebble count data collected using the zig-zag pebble count procedure (Bevenger and King, 1995). The spreadsheet helps users estimate sample size, enter field data measured using the zig-zag protocol, produce tables and graphs, and perform statistical analysis using contingency tables and the Pearson chi-squared statistic. After downloading, to execute the spreadsheet users must select "Enable Macros" for the spreadsheet to function properly.
