Influences of Drainage Construction on the Natural Environment

The natural environment includes habitats of animals and plants that are affected by drainage work. Wild and non-wild flora and fauna living in natural lands face various problems for drainage canals construction. Every aspect of the landscape is adversely affected by the accumulation of salt and harmful substances. In principle, the morphological change of the land created undesirable conditions by removing natural greening. This mechanism leads to erosion of wildlife and loss of habitat.

A drainage constructed with a natural stream and a drain will function as an outflow of surface water and a drainage port of an underground drainage system. Embankment erosion is a gradual decrease in these drains, scouring and collapse (Figure 6). Inappropriate construction, inappropriate maintenance, invasion of unmanaged animals, planting too planted can cause problems of bank erosion. The effect of soil erosion on water is more than the removal of precious topsoil. The emergence, growth and yield of crops are directly affected by loss of natural nutrients and fertilization. Seeds and plants can be disturbed by erosion or completely removed. The organic matter from the soil, the residue, and the applied fertilizer are relatively light, and can move easily from the open air, especially under spring melt conditions. Insecticides can also be removed from places with corrosive soil

The sustainable urban drainage system reproduces the natural drainage method. Effluent water is collected and stored for natural purification prior to penetration or controlled release into the waterway. Therefore, they can prevent contamination, prevent flooding, replenish groundwater to natural water levels, and improve the environment. Filter drain pipe and permeable surface are devices with a certain amount of permeable material underground to store groundwater. Water flows out through the permeable surface into a storage area such as a gravel paving area or a solid paving block with a gap between the various units. When the water falls, the water passes through the surface and enters the permeable packing of the filter drain. This makes it possible to store, handle, transport and penetrate water, and clean water that is not contaminated will return to the ground.
