The first model gives the immersed weight longshore transport rate of sand, Il, as proportional to the longshore component of wave energy flux (power), Il = K(ECn)b sin αb cos αb, where E is the. (Fig. 4) is responsible for longshore transport. The wave energy flux method of Coastal Engineering Research Centre, Vickberg, USA (SPM, ) is the commonly used method for estimation of the longshore sediment transport. This method is based on the assumption that the longshore transport Q depends on the longshore component of energy flux P.

INTRODUCTION The Shore Protection Manual (SPM) (U.S. Army, Corps of Engineers, Coastal Engineering Research Center, ) describes procedures for estimating quanti-ties important in coastal engineering design.

Among the most important of. The energy flux method is an empirical formulation is described in the Shore Protection Manual (US Army Corps of Engineers, ) as (5) Q= KP lb (ρ s −ρ w)ga′ where Q is the volume transport rate and K=empirical coefficient, K= when P lb is based on significant wave heights; P lb =longshore energy flux factor at breaking; ρ s.

Longshore Transport Prediction — SPM Equation A derivation based on conservation of energy shows that P l is the longshore component of the energy flux confined between two wave orthogonals spaced a unit distance apart in the longshore direction, and that a term previously identified as the onshore component of energy flux is.

The relationship between the longshore component of wave energy flux (P~ = (EC,)b sin 0{b COS ~b) and the immersed weight of the sand transport rate (/~) suggested by Komar and Inman5 is as follows I~ = K(ECn)b sin a~b COS a~b (2) where (Efn)b is the energy flux of the waves evaluated for the breaker zone and K a dimensionless coefficient given.

The first paper proposes a general longshore transport model with a main advantage respect to other formulae: it belongs to the well physically based category derived from the energy flux approach (Bayram et al.,Inman and Bagnold,Komar,Komar and Inman,U.S.

Army Corps of Engineers (USACE), ) and it is suitable for. A well-known representative of this type of equation is the SPM formula (Shore Protection Manual, ): IL = KI PL (1) IL is the immersed-weight transport rate, PL is the longshore energy flux at the break point, K~ is a non-dimensional coefficient.

The distributions of longshore and on-offshore sediment transport rates in a surf zone were measured by an apparatus which was able to record separately both components of the sediment transport rate.

Jackson, in Treatise on Geomorphology, Sediment Transport. The prediction of sediment transport rates and directions, both cross-shore and longshore, has been one of the holy grails of coastal science since Cornaglia ().

Longshore transport models have typically been based on simplistic empirical relationships; attempts to quantify sand transport in the. methods to predict the longshore sediment tran sport rate have not been as successful.

Although breaking waves are responsible both for driving currents and mobilizing sand. The linear relationship between wave energy flux factor and the total rate of longshore sediment transport contained in the commonly used CERC predictive formula is supported by the streamer trap.

Ininland seas, such as the Great Lakes, a longshore transport rate in one direc-tion can normally be expected to be no more than aboutUUU cubic meters(, cubic yards) per year.

For open ocean coasts, the net rate of trans-port may vary f to more than million cubic meters (, to 2million cubic yards) per year.able to predict longshore transport accurately in the field (Komar, ). The data are not meant to provide average long-term data at (a) specific site (s).

It is rather assumed that if a longshore transport formula is capable of accurately predicting transport rates for the data sets given herein, it can.
