Qr = (P*Fr^2)/(E*T)
This formula uses 5 Variables
Variables Used
Fresh Water River Flow - (Measured in Cubic Meter per Second) - Fresh Water River Flow is the degree of mixing in an estuary and can be approximately related to the ratio between the volume of the tidal prism and the river flow.
Volume of Tidal Prism - (Measured in Cubic Meter) - Volume of Tidal Prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, or the volume of water leaving an estuary at ebb tide.
Froude Number - Froude Number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross section or between boulders.
Dimensionless estuary number - Dimensionless estuary number has the advantage over the stratification number that its parameters can be rather easily evaluated.
Tidal Period - (Measured in Second) - Tidal Period is an efficient way of guesstimating how much water there is, at any given time of day, over a particular point.
STEP 1: Convert Input(s) to Base Unit
Volume of Tidal Prism: 40 Cubic Meter --> 40 Cubic Meter No Conversion Required
Froude Number: 10 --> No Conversion Required
Dimensionless estuary number: 6.154 --> No Conversion Required
Tidal Period: 130 Second --> 130 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qr = (P*Fr^2)/(E*T) --> (40*10^2)/(6.154*130)
Evaluating ... ...
Qr = 4.99987500312492
STEP 3: Convert Result to Output's Unit
4.99987500312492 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
4.99987500312492 4.999875 Cubic Meter per Second <-- Fresh Water River Flow

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.
