Seawater intake structures are important coastal structures required for the intake of seawater for various coastal-based industries like thermal power plants, desalination plants, chemical plants and coastal aquaculture. Physical model study was carried out on a seawater intake well model consisting of an impermeable cylinder encircled by a circular porous cylinder in the Department of Ocean Engineering, IIT Madras, India in a wave flume of 2 m wide, 1.7m deep and 30 m length to determine the effect of porosity of a seawater intake caisson on wave forces on the well and water surface fluctuations around the intake well. The experimental investigation was carried out for random waves in a constant water depth of 0.7 m by varying the porosity of outer caisson from 4.54% to 19.15%. This paper presents the simple predictive formulae for wave loads and water surface fluctuations around the well due to regular waves.
