Soil Erosion
Soil is produced naturally when small pieces of weathered rocks and minerals are combined with organic materials from plants and animals which are rotting. The formation of soil is a slow process that takes several years. The created soil, however, is constantly subjected to natural and manmade forces which disrupt it.
Soil erosion is defined as topsoil wearing away. Topsoil is the highest layer of soil and is the most fertile because it contains the most organic materials rich in nutrients. So this is the layer farmers want to protect for growing their crops, and ranchers want to protect their cattle for growing grasses to graze on.
Flood
Flood is one of the most common natural hazards, which is a natural phenomenon of an extreme nature, often violent, occurring irregularly. In accordance with art. Flood is defined as “a temporary coverage with water of an area not normally covered by water, in particular caused by high water in natural water-courses, reservoirs, onshore canals, excluding coverage of an area with water caused by high water in sewage systems”.
Canal Filters for Flooding
Our proposal are canal filters that would help reduce flood. The first canal filter is consisting of 2 layers of net. The inner layer would be for the normal sized trashes just like bottles, wrappers, etc. While the outer layer would be for the smaller particles of trash or sediments. These layers would be placed at the end of the canals. The second canal filter is made out of metal. This filter would be hanged inside the canals so that the trashes would not flow with the water in the canal and it wont clog the drainage. This canal filter would be covered with metal grills.
Our second canal filter is made out of nets. This canal filter consists of 2 kinds of net. The inner layer of net would be for the usual kinds of trashes like plastic bottles and food containers. The outer layer would be for the small particles of trash and sediments. These nets would be placed at the end of the canal.
