reading beaches

Found an article online before about reading beaches with diagrams etc. but cant seem to find it now. I think its something i need to look into some more. anyone have any info on this? would you consider it a vital part of shore fishing or do you just lob out baits in the hope of landing in the fish?

Cheers

i always look out for gullys or little trenches
