Approx perimeter of ellipse = pi( ((3*length)+(3*width)) - sqrt((length+)+(3*width))*(width+(3*length))) )
Hydraulic Radius = Area / Perimeter
Or something like that...

Thanks for pointing out that I'd used ellipse "diameter" as opposed to "radius" in my equation, giving an area four times the size it should have been!!!
