User's Manual for NAVEFF Navigation Effects Model

Abstract

The analysis of system-wide impacts begins with the Navigation Effects (NAVEFF) model. This user guide provides a detailed description of the NAVEFF model installation and execution. The format of the NAVEFF input and output files is documented in this user's guide. The NAVEFF model is a one-dimensional model that estimates the physical forces generated across a cross section caused by shallow draft navigation of a tow boat. NAVEFF is run at each half mile cross section for pools 4, 8, 13, 26, and LaGrange and at 1 mile cross section in the remaining pools. Inputs for NAVEFF are 108 different tow boat combinations, three river stages, and three sailing line locations. Output from NAVEFF includes maximum velocity change, maximum drawdown, maximum wave height, maximum bed scour, and maximum bed shear stress. The output from NAVEFF is one of the primary inputs to the other system ecological models and the sedimentation model.
