Abstract: An approximate matching technique uses separate solutions in a semi-infinite ocean bounded by a straight coastline, a harbor basin, and a narrow straight entrance channel which connects them. Wave height and velocity are matched at the interfaces. Such an approach allows different solutions to be used in any of the three regions, when the physical description of that region is modified, without changing the solutions used in the remaining regions. In the present work, the entrance channel is first considered to possess a wall/bottom friction although the remaining regions are kept frictionless. Results indicate that the channel effect, which leads to increasing resonance amplification with increasing channel length analogous to the well-known harbor paradox, is counteracted by the increase in frictional effects for a longer channel. The second problem considered modified the entrance channel to have a linear slope from a constant depth ocean to a harbor basin at some other constant depth.
