IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Unidirectional wave spectrum models for chabahar bay, gulf of oman

ABSTRACT
There are different well-known wave spectra models; each useful under certain circumstances. These models are
extracted based on field data at specified regions and wisely or blindly extended overseas. Even though, such approach
of implementing a standard spectrum model is practical, however, error is its inherence. Appropriate unidirectional wave
spectrum models for Chabahar bay at the north of Gulf of Oman are introduced in this paper. Wave filed in this region is
mostly combination of seas and swell waves. Thus, observed wave spectrums have two peaks especially in monsoon
season. The research is firstly focused on assessing performance of standard wave spectrum models in the region. By
evaluating such models; calibration procedure has been conducted on such standard models using the valuable recently
published measurement data to reach a better concordance between a modified standard spectral model and observed
field spectra. Results show that for observed spectrum with one peak standard ITTC model is extremely more
appropriate in this regions when compared with PM and JONSWAP models. However, for observed spectrum with two
peaks standard Ochi-Hubble model performance is not appropriate and should be calibrated for this region. In order to
catch a calibrated version and increasing the accuracy, the constant values of ITTC and Ochi-Hubble models are
changed by applying GRG algorithm and modified versions of ITTC and Ochi-Hubble models are introduced as the best
practical unidirectional spectra in Chabahar bay.
