Inlet Impacts on Adjacent Beaches - IIAB Java Program User's Guide
PURPOSE:
This Wiki-Technical note provides a User's Guide to the IIAB Java Program, which is available for download on the CIRP website: [[1]]. For an inlet system bounded by adjacent beaches, the IIAB Program uses methods outlined in the Coastal Engineering Manual (CEM) Part V-6 to estimate the alongshore extent of inlet impact based on the volume captured by the inlet. The user can load shoreline position, ebb and flood shoal volume (or volume change), and Operation & Maintenance (O&M) dredging volumes (or volume change) data to view plots and results.

INTRODUCTION:
The Inlet Impacts on Adjacent Beaches (IIAB) Java Program applies methods discussed in the Coastal Engineering Manual (CEM) Part V-6 to estimate the volumetric impact of an inlet on the adjacent beaches. Generally, the methods balance volume change on the updrift and downdrift beaches with the volume captured by the inlet, accounting for Operation & Maintenance (O&M) dredging (Figure 1).
