Journal ArticleDOI
TL;DR: In this paper, a finite difference-based three-dimensional modeling has been conducted to evaluate tidal power density at different locations along the Gulf of Khambhat, India, using the Navier-Stokes transport equation in 3D plane under the assumption of shallow water and Boussinesq.
Abstract: A finite difference–based three-dimensional modeling has been conducted to evaluate tidal power density at different locations along the Gulf of Khambhat, India. The model uses the Navier–Stokes transport equation in three-dimensional plane under the assumption of shallow water and Boussinesq. The model results were validated with observed water levels and currents available in the literature. The Gulf has strong and varying currents and associated circulation patterns, especially in the northern region, due to complex bathymetry. The current velocities and corresponding power densities were computed for different vertical layers of the entire model domain. The maximum tidal current velocities are found in the northern region along the narrowing part of the Gulf. The estimated values are 2.6 and 1.5 m/s during spring and neap tidal cycles, respectively. Then, the energy flux approximation method has been used to estimate the tidal power densities along the gulf spatially and temporally. The estimated maxi...

TL;DR: In this paper, a frequency domain wave model (STeady-state spectral WAVE) has been used to compute the nearshore wave climate and the longshore sediment transport rate is obtained through empirical relations.
Abstract: Tidal inlets get disconnected depending on the seasons due to the formation of sand bars near its mouth are termed as “seasonally open tidal inlets.” These inlets are usually small of width of about 100 m and occur in micro-tide (tidal range not exceeding 1 m). Since the east coast of India experiences a net littoral drift of up to about 0.8 Mm3/annum, which is one of the largest in magnitudes that needs to be considered in the analysis of modeling of the sand bar formation and the associated phenomena. Kondurpalem inlet situated along the South east coast of India is considered as a case study. A frequency domain wave model (STeady-state spectral WAVE) has been used to compute the nearshore wave climate. The wave-induced currents have been obtained, and the longshore sediment transport rate is obtained through empirical relations. The tidal prism is found from measured depth and tidal velocity by solving shallow water equations. The stability of the inlet is investigated by applying the criteria develope...
