what problems are caused by dredging out wetlands

Such equipment normally has better noise and vibration attenuation than older machines. Noise can obviously be reduced by noise fences or similar structures, but these are often impracticable on roadwork sites, particularly for minor works of short duration.Ī general piece of advice that applies to noise is to use modern equipment wherever possible. There are only limited ways of reducing the noise level. Where this is impossible, the persons affected should be given special notification. It is wise to work within normal working hours as much as possible. If people are notified, their acceptance of the disturbance is usually higher.

For major work, it may be sensible to convene an information meeting. This can be done by delivering information leaflets through letterboxes and/or by posting notices on notice boards. Noise disturbances may cause irritation as well as agitation and stress to livestock.Ī simple but fairly effective measure to manage the effects of noise is to notify the persons likely to be affected that work is about to start. Greater consideration must therefore be given if roadworks are likely to create noise.

For example if a road is in poor condition and cars are traveling fast, this can cause more noise than if the road is in good condition.

The condition of roads has an effect on noise level. This lesson will focus on the environmental effects of noise, dust, vibrations, and other environmental concerns, and offer suggestions on how they can be mitigated. Vibration can be caused by uneven road surfaces and can pose significant impacts and problems to houses close to the source. Excess dust production can be treated by a range of means such as watering, the use of alternative materials, and by using dust binders near houses. Dust is created during the construction of gravel roads and unbound aggregate layers. Noise mainly occurs during road construction phases but it can also occur to a lesser degree during maintenance operations. The three most damaging effects of road construction and management are noise, dust and vibrations. They can also cause adverse impacts on natural water resources and discharge areas. On the negative side roads occupy land resources and form barriers to animals. On the positive side roads provide the opportunity of mobility and transport for people and goods.

Roads can have both positive and negative influences on people and the environment.
