Ano Ang Solusyon Ng Erosion

Answer:
Company operations within the mining, civil or infrastructure industries often require project removal of vegetation, this, however, exposes the bare substrate to environmental factors prone to causing soil erosion – a national issue, recognised for the detachment and movement of soil material caused by water, wind and human interface. Despite moving at a slow and often unnoticeable rate, it can take a dramatic turn and alter your project site at an alarming level by removing excess soil and impinging on the project budget.
It is vital to maintain a strong understanding of the substrate in which you operate and recognise the environmental characteristics that require active preventative measures. Planning should include temporary and long-term solutions including, topsoil management, dust suppression, revegetation and or erosion control processes to support the substrate’s mechanical structure and keep the soil in place.
The following information opens up awareness into the signs of soil erosion and the onsite effects that may impinge on worksite operations. The key to avoiding such issues is to know the problems around soil erosion, what to look out for, what control methods to put in place, and how to implement long-term solutions into your project planning.
Cause & Effect
Preparation, planning and awareness are critical factors in preventing the damaging effects of erosion on site. Water, wind and project mass movement are the main contributors to the removal of soil. The following wind and water processes highlight how quickly erosion can impinge on a worksite and underpins the importance of thorough substrate evaluations.
Water
Water under the influence of intense gravity force can entrench wear on all substrates surfaces causing particle dislodgement, transportation and removal. The energy displaced by rain followed by water runoff, both contribute to escalated stress on the substrate resulting in detachments and transposition of soil.
These processes occur at different scales and are dependent on the depth of erosion. The longer an issue is unresolved, the bigger the solution and amendments that are required. The following erosion issues bellow provide insight into how water can affect your project site.
1. Splash erosion: The first stage of water erosion, triggered by the force of rain impacting on a bare substrate. The strength of the water breaks away aggregate, splashing soil particles as high as 60 centimetres and displacing them up to 1.5 meters away from the point of force. If this issue persists, it can prompt impacted surface crust which will reduce the infiltration properties of the substrate, causing runoff and transportation of soil.
2. Sheet erosion: stemmed from splash erosion, causing the uniform removal of substrate layers. If the process endures, it can go unnoticed for an extended period, and if the area is unattended gradual removal of nutrients and organic matter will contribute to the ill effect unproductive soil.
3. Rill erosion: the direct force of water and soil moving across a substrate, trailing an open channel. The water gradually opens up the channels and increases the detachment and transportation capacity of the substrate by disrupting the soil, plant development, and reducing landform sustainability.
4. Tunnel Erosion: a dangerous form of erosion stemmed from water permeation into soil cracks, holes or root decay, causing tunnels below the substrate. The surface structure remains intact, until the flow of water beneath increases in the width of the tunnel, causing the top layer to collapse. The process rate increases if an outlet such as an existing rill or roadside cutting intersects the tunnel providing free flow of water drainage.
