Improving the Entrance to a Bar Harbor by a Single Jetty
In devising plans for the improvement of the entrances to the tidal harbors of the United States, the general system adopted has been to confine the outflowing and inflowing waters between parallel or converging jetties so located and arranged as to direct the waters upon the bar in a fixed position. Where single jetties have been planned, as at the mouth of the Columbia and San Diego, it has been because the other jetty was replaced by headland or permanent shore. The author's experience in charge of the improvement of a number of harbors on the Pacific Coast has convinced him that there are places where the double jetties are unnecessary and where a single jetty, if 'properly placed, will, in conjunction with natural tendencies, compel the entrance channel to adopt a fixed and permanent location and practically accomplish all that could be expected of two jetties, and at half, and sometimes less than half, the necessary cost of a pair.
