The rain garden should not be located straight over a septic system, it should also be built in sun and not under obstructions such as canopied trees among pother siting issues. The residential code regulates the construction of a rain garden by providing guidelines which must be followed. The cost of constructing rain garden is another inhibiting factor as the design should be deep enough to be costly.
User profiles and needs: Surveys and interviews were conducted from different residents affected by the run-off during the rainy season to assess the extent of the problem. The users reported the following problems; Increase in pollution, Erosion of soil causes Sedimentation, Metal pollutants harm aquatic life, Stagnation of water increases the number of mosquitos, Contamination of water bodies with pesticides and Contribution of high temperatures among others. The problems are illustrated in the Pareto chart below.
Design objectives: the design objects to solve the problem of the residents who experience high rates of surface run off during the rainy season. The design should be able to withstand percolation of water which reduces the amount of water running to the water bodies causing floods. The rain garden is designed to capture excess rainwater from hard surfaces which cannot percolate water such as driveways and cemented surfaces. The rain gardens are designed with beautiful flowers which can be attractive especially when in urban areas with poor drainage. The rain gardens are constructed with special features which enable them to capture the excess surface run-off. There are layers of sandy soil below the rain gardens which reduce the rate at which water enter the water bodies and the creeks. They are also effective in the removal of pollutants caused by fertilizers, nitrogen, dust and other wash off pollutants from the hard surfaces. Rain gardens are very effective as they can be maintained even in urban areas; they reduce runoff and protect the

For the Protection System of Hurricane, there are two wide classes of alleviation options. The primary option is to lessen the likelihood of torrents by bettering the levees systems, walls, pumps and gates. The subsequent option is to lessen the results of flooding by bettering the system for setting up, alarming and shifting people and guarding property, mainly through communication and public education (Hallegatte, 2006) in addition to through guiding, public principle and inventive engineering solutions to migration and assets recovery and protection.
During the flood, the water in the river rushes out of the river and risks the lives and the property of people residing nearby. On the other hand it harms the irrigated fields and plants. It is the force of water that is considered the most dangerous during the flood.

Local application of fire suppression mechanisms on coal mine fires is ineffective as the combustible nature of coal implies that fires can spread easily and haphazardly. This is further exacerbated by coal dust as heat can be transferred easily to other areas.
In real storm events, flow of water is constantly changing as floodwater is stored out of the river and return to its original level as water subsides. The prediction of the behavior of water in the environment is more complex. The run-off generated by rainstorm will depend on the soil type.
A tornado describes a violent storm. It originates from powerful thunderstorms. A downburst develops from fast moving air flow from a thunderstorm. Although both a tornado and a derecho has devastating effects,
