Specific issues of British Railway Modelling

[ohlavache]

Hello.
For a new project I have in mind, I am collecting information from several sources on how to model the sea and the beach. Here I need people who have subscribed to British Railway Modelling in order to determine which issue(s) I should order.
Can you please tell me which of them are useful tutorials about maritime scenery ?

- July 2012, Vol.20 n°4, How to create sea-water & How to model a beach
http://www.rmweb.co.uk/community/index.php?/topic/56959-brm-july-2012/

- August 2013, Vol.21 n°5, Model a beach scene
http://www.rmweb.co.uk/community/index.php?/topic/73629-brm-august-2013-issue/

Are these two issues redundant or complementary ?
If redundant, which one is the more useful and instructive ?

Thanks by advance for your help.

Thank you for your two replies. 
I'll try to find the index of the book you suggested.
On Model Rail web site, one cannot search for a specific topic among past issues. 
I was only able to find these two issues in BRM.
