for virtually any situation. He developed a generalized formulation of rope influence in the basic equations of moored ship motion in waves and surges, including the strong nonlinearity of both elastic properties under cyclic loading and catenarian configuration (from which the conditions under which a ship could rupture its mooring lines or crush the fenders are determinable). Following his extensive analysis of the large and damaging tsunami from the 1964 Alaskan earthquake and study of earthquake incidence worldwide, estimates of tsunami hazards have been developed for a number of locations, particularly nuclear power plants. He has been responsible for major advances in techniques for wave prediction (particularly with moving fetches), hurricane surge and flooding prediction, submarine pipeline stability under wave loading, and wave forces. His insight into the physical background and his mathematical capability, coupled with his thoroughness and determination, have left a major engineering legacy in the coastal field, furthering materially the knowledge base for the civil engineering discipline.
These achievements came despite a progressing deafness, which at times made communication difficult, and which influenced him to go into engineering rather that follow in his father's footsteps as a journalist. But his love of writing remained throughout his life, as shown not only by his technical literature, but by his poetic children's books and his lengthy annual Christmas poems summarizing the past year.
