Thick person asks O-Level geography question

[GJ0KYZ]

If a river has a lot of water in it during the winter, will the high tide mark be higher than during the summer (for the same height of tide) when there will be less river water?

[bosun]

I would guess it depends how far up river you go,the rising tide will tend to push the rainwater coming down river back up and that's what can cause flooding.Worse on spring tides of course.
I havn't given this a great deal of thought mind,its just that locally we have a river that bursts its banks only when its been raining heavily and the tide is in.

[Erin]

Would have thought so. The tide will push in and hold back the natural flow of river water, resulting in it rising to a greater degree.

Having lived with a tidal river at the bottom of the garden I can say with some certainty yes. Though I have no idea why, but then I struggle to work out why the river goes backwards while falling. Tides eh, what fun!

[martini]

I'd say no, any extra water would just flow out, creating a stronger ebb?

[Searider]

Yes,

Southampton water tide tables warn that tidal heights may be higher after heavy rain.

[Channel Ribs]

Mind you, rain usually ties in with low pressure. Low pressure can be associated with higher tides.

I think, not even sure what day it is now.

Ask my mate who lives on the edge of the Brisbane river. When he's finished mopping up that is!!
