Tillamook Inlet, OR

[1] Tillamook Inlet is a structured, deep-draft navigation project of the USACE Portland District, located along the northern Oregon Coast. This two-jetty system serves the entrance channel of the Tillamook Navigation Project, which provides ocean access to the Port of Garibaldi. The CIRP is conducting a study to evaluate the present and past behavior of the ebb-tidal delta, or bar mouth, and how the waves and currents interact at the entrance channel. The primary morphologic end states of the ebb-tidal delta will be analyzed within the context of various physical forcing using the Coastal Modeling System (CMS) to determine the influence morphology has on the waves and currents at the bar mouth. A secondary objective is to evaluate how the present jetty configuration plays a role in the various bar mouth (ebb delta) morphologies that occur and transition over multi-year cycles.

Nearshore Berm Webinars

The Regional Sediment Management and Coastal Inlets Research Programs will co-host a series of webinars on the topic of coastal nearshore placement. The two programs have collaborated on the research topic of nearshore berms over the last two years to develop improved documentation of projects and general guidance for this operational activity within a regional context. The Nearshore Placement Webinar will cover the recent advancements and techniques used by researchers at ERDC to address questions about nearshore placement. There are a number of approaches that are often employed for a particular environment, and this meeting is intended to demonstrate different technology developed at ERDC. Follow up webinars will be open to suggestions, but it is important that this venue serve as a discussion board across disciplines and business lines within the USACE Districts. The first Nearshore Placement Webinar is scheduled for the afternoon of November 6th, 2012. Details will be posted on the CIRP and RSM websites: cirp.usace.army.mil or rsm.usace.army.mil.

Lab Tests to Evaluate Innovative Sediment Management Technology

The Coastal Inlets Research Program (CIRP) gave two weeks of instructional webinars on the Coastal Modeling System from 11-15 and 18-22 June 2012. The first week was "Coastal Modeling System Basics" and the second week was "Advanced Coastal Modeling System Modeling". Each instructional webinar was two hours each day of the week and went through hands-on instruction and examples of advanced CMS applications. Approximately 50 participants attended the first week, taught by Mitchell Brown, and 42 participants the second week of webinars which had Alex Sanchez as instructor. Attendees originated from USACE District offices, State agencies, consulting firms, and academia in the U.S. and the international coastal engineering community.

The CIRP is offering one more webinar in the series, "Regional Coastal Shoreline Evolution Model: GenCade" taught by Ashley Frey on 16-18 Oct. For more information, to download presentation and example data files, and to register for future webinars, please see the CIRP website:

Upcoming GenCade Webinar

On February 8, 2012, Major General Walsh introduced a "3x3x3" rule for conducting Feasibility studies. The new 3x3x3 rule states that all feasibility studies should be completed in no more than three years, at a cost of no more than $3 million, utilizing 3 levels of vertical team coordination, and of a "reasonable" report size. CIRP is working to streamline data preparation and connectivity between models and databases to help you in this more rapid process. But we need your input! We are very interested in what you need to help you accelerate quality feasibility studies. Please let us know what would help you in getting these studies done.

First Announcement: 14th Annual CIRP Technology Transfer Workshop

CIRP and the New England District (NAE) are conducting a nearshore modeling study at the Merrimack Estuary, Salisbury Beach and Plum Island, MA. The Coastal Modeling System (CMS) will be set up to simulate waves, currents, and sediment transport for combined hydrodynamics and wave action to evaluate a variety of structural and non-structural alternatives. The study will examine erosion on Plum Island downdrift of the inlet and the reduced navigability of the inlet under various ambient conditions and project alternatives. The simulation results will provide the technical information necessary for NAE and the local sponsor to develop a sand management strategy for the inlet and adjacent beaches. The study findings will be documented in a technical report.
