Salinity at Moment of Slack Water

Go Salinity at the Moment of Slack Water = Salinity of Water*exp(-(18*10^-6)*Fresh Water River Flow*Coordinate along the Channel^2-(0.045*Fresh Water River Flow^0.5))

Apparent Dispersion Coefficient which includes all Mixing Effects

Go Apparent Dispersion Coefficient = (Diffusion Coefficient at x=0*Distance outside the Estuary)/(Coordinate along the Channel+Distance outside the Estuary)

Coordinate along Channel given Apparent Dispersion Coefficient

Go Coordinate along the Channel = (Diffusion Coefficient at x=0*Distance outside the Estuary/Apparent Dispersion Coefficient)-Distance outside the Estuary

Diffusion Coefficient

Go Diffusion Coefficient at x=0 = Apparent Dispersion Coefficient*(Coordinate along the Channel+Distance outside the Estuary)/Distance outside the Estuary

Froude Number given Dimensionless Estuary number

Go Froude Number = sqrt((Estuary Number*Fresh Water River Flow*Tidal Period)/Volume of Tidal Prism)

Fresh Water River Flow given Dimensionless Estuary number

Go Fresh Water River Flow = (Volume of Tidal Prism*Froude Number^2)/(Estuary Number*Tidal Period)

Tide Period given Dimensionless Estuary number

Go Tidal Period = (Volume of Tidal Prism*Froude Number^2)/(Estuary Number*Fresh Water River Flow)

Dimensionless Estuary number

Go Estuary Number = (Volume of Tidal Prism*Froude Number^2)/(Fresh Water River Flow*Tidal Period)

Volume of tidal prism given dimensionless estuary number

Go Volume of Tidal Prism = (Estuary Number*Fresh Water River Flow*Tidal Period)/Froude Number^2

Rate of Potential Energy Gain given Dimensionless Stratification Number

Go Rate of Potential Energy Gain = Rate of Energy Dissipation/Stratification Number

Rate of Energy Dissipation given Dimensionless Stratification Number

Go Rate of Energy Dissipation = Stratification Number*Rate of Potential Energy Gain

Dimensionless Stratification Number

Go Stratification Number = Rate of Energy Dissipation/Rate of Potential Energy Gain

Estuary Number given Froude Number and Mixing Parameter

Go Estuary Number = Froude Number^2/Mixing Parameter

Mixing Parameter given Dimensionless Estuary number

Go Mixing Parameter = Froude Number^2/Estuary Number

Estuary Number given Froude Number and Mixing Parameter Formula

Estuary Number = Froude Number^2/Mixing Parameter
E = Fr^2/M

What is an Estuary?

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.
