Sandbags are amazingly helpful when it comes to protecting small areas from floods. Sandbags are very easy to create. All you need is sand, polyethylene sheeting, a shovel, a bag for the sand, and wheelbarrows. These are easily available in any hardware supplies store. That’s it! You are now ready to make a sandbag of your own in four easy steps.
With the help of another person to hold the bag, fill it with sand. Make sure the bag is only half full and ideally should weigh less than 40lbs.
Once the sand is filled, the empty part of the bag should be folded and placed that side down. This will prevent water from seeping in. A single sandbag that leaks can ruin the whole pile.
A trench measuring 5 inches deep and 20 inches wide has to be dug around the area that needs to be protected. The polyethylene sheeting has to be laid on the trench and be secured by sandbags that are placed in such a way that they directly face the flowing water.
Create new rows only after completing a row as leaving space is not advisable. The best way to build a stack of sandbags is to build it similar to how brick walls are created. This adds more protection to the sandbag wall being built. Normally a three layer stack of sandbags are considered to be sturdy enough and hence sticking to a three layer stack is advisable.
That’s all! The sandbags are now ready to protect against flooding. These sandbags can be preserved to use for the following rainy seasons. Enough care has to be taken to ensure that the bags are prevented from repeatedly getting wet. This will give them a longer life span. Also, when not being used the bag has to be emptied and kept aside for use next year.
Though sandbags are wonderful at protecting, it must be noted that they are best suited for certain jobs. A two person team will have difficulty protecting a large area. Soil can be a good substitute when sand is not available, and filling the bags with cement will create a more permanent barrier than sandbags.
Sandbags are used to create a wall wich has a water tight seal to keep the water out and protect selected areas.
Landlord insurance can protect against disasters that would cost money for the landlords complex. These disasters can include fire, lightning, explosions, earthquakes, storms and floods. However, it varies between policies.

Well, there are many reasons as to why the Three Gorges Dam is and is not sustainable.Sustainable:Will hold up against floods- protecting precious agricultural land and peoples lives.Will protect the Yangtze river from landslides-stops sediment from blocking up the rivers path.Not sustainable:Will not hold out against typhoons (tornados or hurricanes in America)-they will just rip it up.Will not hold out against huge floods-giant floods will go over the top of the dam-letting water through and causing flooding on the land and increase water levels.
Most of us are familiar with sandbags in the movies. They feature prominently in most war and action films, since they are a cheap and inexpensive way to give soldiers and heroes something to hide behind in a firefight. However, most sandbag use is domestic, and is intended to protect against water and flooding as opposed to enemy bullets. As such, it is important for any homeowner to know about sandbags and the difference between a good sandbag and a bad one, especially if they live near a river or in a flood-prone area. The typical modern sandbag is a step up from the burlap sacks that were used as late as the 1700s to protect against floods and storms. Made out of a thick nylon weave, these bags usually hold about 50 pounds of dry sand, although there are smaller ones which hold as little as 10 pounds for when detail work is needed. A good sandbag will have a tight weave and firm material that cannot easily be torn or cut. The tight weave should be such that when the sandbag is picked up by the top or in some cases even the handles, that no sand leaks out of the bag. Sandbags that are tied off at the top should have steady, secure ties, such as zipties or nylon rope. In general, sandbags are sold empty in large lots, and purchasers should always examine a few sample ones from the lot before purchasing. Sandbags need to be made cheaply and in large quantities, so if they have a bad stitch or poor weave, or have begun to dry rot, then they may be unable to hold the sand. When using sandbags, it is important to overlap them like bricks so that their weight and mass can plug the holes and gaps between them. It is generally considered that a wall of sandbags intended to prevent a flood be at least three bags thick, more if the flooded river is very powerful or the wall needs to be taller. When using sandbags to prevent erosion, it is often possible to get away with a wall of bags, which is a single bag thick, since they will be backed up by advancing dirt and gravel. Sandbags are not a permanent solution and they should be inspected regularly, since most of them begin to degrade and break apart in sunlight. Sandbags sand bag bags flood prevention retaining wall

So far as we know in 2015, Mars does not have any running water to create floods.
The Goverment helps by supporting the people and taking the time to bring sandbags to the people and making places open there buldings to people so they have somewhere to live while the flood is there.
