I thought this site may help me find out tidal time cycles on rivers but it does not realy help. ie. there is a two hour difference between high water at immingham & Owston ferry, I didnt think there would be much diference in the same locality.
Can ony one point me towards a source of information for tidal times on rivers, ive done a bit of web surfing but can't find any. ( I emailed the EA about a week ago but have had no answer)
