The military has used sand bags for many years to absorb shock and projectiles. Sand disipates energy so when a bullet hits it, the shock is spread out among all the grains and the bullet stops. Soldiers hide behind sandbags to protect themselves. Sandbags can also protect buildings from the shock wave of bombs.
A parapet was used to provide cover for soldiers as they moved about and fought in their trenches. (Note: a parapet was simply a vertcial extension of the trench, typically made of sandbags or piled earth, placed on the lip of the trench facing the enemy.)

It will be alot of work but you can always use sandbags and shovels to build a trench.
A trench was set up in a zigzag shape to make it a less target for the opposite side to target. It consisted of sandbags, barbed wire, fire steps and unsanitary places to do your business.
To effectively use sandbags to stop a flood, place them in a staggered pattern to create a barrier against rising water. Make sure the sandbags are tightly packed and stacked at least two layers high. Additionally, place a plastic sheet or tarp behind the sandbags to prevent water from seeping through. Regularly monitor and reinforce the sandbag barrier as needed to maintain its effectiveness in preventing flooding.
Decide on the size and location of your trench. Measure the location and decide how deep and wide your trench should be. Clear the area of any debris or obstructions. Dig your trench. Use a shovel, pickaxe, or other digging tools to excavate the soil. Make sure to maintain a deep, consistent depth throughout the entire trench. Line the trench with sandbags. Place sandbags along the sides of the trench to reinforce it and provide a protective layer. Line the bottom of the trench with sand or gravel. This will help with drainage and prevent the walls of the trench from caving in. Add any additional reinforcements, such as wood or metal beams. Add a roof or overhead cover to protect soldiers from enemy fire. Add any additional features, such as dugouts, communication posts, or fire steps. Cover the trench with dirt or soil. This will help to conceal it and keep it from being an obvious target.
They are called Breakers.

Each year many towns and cities are devastated by the flooding of bays, lakes, oceans, and rivers.%C2%A0 While flooding can occur without notice, the damaging effects of floods can often be reduced or eliminated with the use of sandbags.%C2%A0 While sandbags are a simple solution, knowing how to properly fill and use sandbags to prevent flood damage can be confusing. %C2%A0 The first step in how to use sandbags to prevent flooding is to create sandbags.%C2%A0 Sandbags can be created with sand found and home improvement stores, beaches, or even a local playground.%C2%A0 Beyond the sand, you will need plastic or cloth sandbags, a wheel barrow, and a shovel.%C2%A0 When filling the sandbags, be sure to fill them until they are about a third of the way full.%C2%A0 When this full, the typical dry sandbag will weigh about 40 pounds.%C2%A0 Then take the leftover slack of the bag to fold over. %C2%A0 The next step in using sandbags to prevent flooding is to build your sandbag wall.%C2%A0 To build this wall, you will first need to dig a trench that is about 6 inches deep and 18 inches wide.%C2%A0 The dimensions may vary if you have larger or smaller bags.%C2%A0 After digging the trench, you will need to place a polyethylene sheet into the trench.%C2%A0 Once the sheet is placed, you will place the first row of sandbags into the trench.%C2%A0 The bags should be laid down so the left over slack from the bag will lie beneath the weight of the bag. %C2%A0 After building your first row of sandbags, the next step in building a sand bag wall is to build the next few rows.%C2%A0 The next row should be placed directly on top of the first row, although the sand bags should be placed in a staggered pattern.%C2%A0 Continue to build up the sand bag wall until the wall is about 4 rows high.%C2%A0 Beyond this point, the bags will begin to lose their sturdiness.%C2%A0 If you need to build your sandbag wall higher than 4 rows, you will need to build a wider trench and create a sandbag base of at least two rows wide.%C2%A0
A trench box, trench shield, trench sheets, are the put into trenches to stop the walls collapsing inwards and injuring or killing the workmen/utility workers, etc, working in the trench.
