Sand bags are good but soon rot … i prefer this method
Ferro-cement is a method of construction ( there are many ways to do it but here is mine) where you make a frame of steel mesh (about 2 inch mesh) … and attach chicken wire to it every few links.
or start with EMPTY Gabion’s , ones of the right dimensions, — preferably a thinner type like 1 a foot thick or less – they are made in many sizes — 3 foot by 4 foot by 1/2 a foot and use them as you would bricks .. tying them together with wire, obviously with the 1/2 foot being the width of the wall.

Then attach the chicken wire to the outside of the wall and what will form the inside and plaster .
Plaster with a very fine plaster mix on the chicken wire — let it set and re-plaster until its quite thick .. maybe 1 inch

please go and read this article i know its long but its relevant
I read this article some time back an found that the information was rather inspirational, a move towards sail powered craft with the knowledge of modern nautical maps and charts as well as combining this knowledge with something like the concrete submarine – or a ferro cement hull, and modern refrigeration, possible steam power , might be an option for a post SHTF scenario when the immediate danger has subsided and you need to find a way to feed yourself and your family … fish stocks in the ocean will soar without the fishing trawlers taking large numbers of fish…
Long term, fishing will be a real option .. and as most rivers lead to the ocean . a life there could be better over all rather then inland … of coarse living near the sea pre-SHTF is not necessarily wise with all the possible natural disasters that accompany it .
any way read the article it speaks for its self.
