This paper assesses the current speed data measured during different sorties across the Bosphorus on the southern coastal areas. The spatial model works on stochastic methodology for the purpose of current speed prediction at different depths within the target area. Current power generation formulation in accord with the current speed probability distribution in the Bosphorus has been developed and a simple numerical sample is presented. The current speed probability distribution function (pdf) accords theoretically with the Gamma pdf. Necessary current power estimation formulation is developed parametrically and by considering the cut-in lower current speed as 1.0 m/s. The application of the methodology for more than 1.0 m/s current speed yields to 0.736 kW power per unit m(2) turbine area and per second. (c) 2012 Elsevier Ltd. All rights reserved.
