rH = D*(Vavg/Vmeas)^(3/2)
This formula uses 4 Variables
Variables Used
Hydraulic Radius - (Measured in Meter) - The Hydraulic Radius is the ratio of the cross-sectional area of a channel or pipe in which a fluid flows to the conduit's wet perimeter.
Depth of Water at Current Meter Location - (Measured in Meter) - Depth of Water at Current Meter Location [length] where current meter is used to measure water velocity at predetermined points.
Max Velocity averaged Over Inlet Cross Section - (Measured in Meter per Second) - Max Velocity averaged Over Inlet Cross Section entirely [length/time] depends on point measurement of maximum velocity, hydraulic radius and depth of water at current meter location.
Point Measurement of Maximum Velocity - (Measured in Meter per Second) - Point measurement of Maximum Velocity [length/time] depends on max velocity averaged over inlet cross section, hydraulic radius and depth of water at current meter location.
STEP 1: Convert Input(s) to Base Unit
Depth of Water at Current Meter Location: 8.1 Meter --> 8.1 Meter No Conversion Required
Max Velocity averaged Over Inlet Cross Section: 3 Meter per Second --> 3 Meter per Second No Conversion Required

What is Tidal Prism?

A 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. It can also be thought of as the volume of the incoming tide plus the river discharge.

What is Inlet Flow Patterns?

An Inlet has a "gorge" where flows converge before they expand again on the opposite side. Shoal (shallow) areas that extend backward and oceanward from the gorge depend on inlet hydraulics, wave conditions, and general geomorphology. All these interact to determine flow patterns in and around the inlet and locations where flow channels occur.
