What is erosion control?
Erosion control is often needed on site during construction when vegetation on site is disturbed leaving soil exposed to wind and rain. Erosion control measures should be part of construction site planning. Some builders will grind up wood scrips to use as a mulch around newly constructed homes to stabilize soil until landscaping is planted. Straw, bark dust, shredded paper, and leaves can also be used as mulch. Straw bales, sand bags, and silt fences can be used temporarily for slope stabilization and to keep sediment out of drainage inlets. Erosion control products like blankets and bags can be used in conjunction with mulch to stabilize sloped ground and disturbed soils and as ground preparation for planting (NRCS).

How to stop erosion on slopes?
One great and natural option to help to control erosion on slopes is by using plants. The roots of plants act as natural ways to hold in the round and soil and anchor the soil. Planting on a slope can be more difficult. Turf grass. Some have argued that turf grass might be the best defense against soil erosion.
What is the best defense against erosion?
Turf grass. Some have argued that turf grass might be the best defense against soil erosion. Turf grass helps to bind the soil together as each grass plant has an extensive root system. In fact, up to 90% of the weight of a grass plant is in the roots.
What is Erosion and What are the Causes?
Erosion is when the top soil is swept away by natural or man-made forces. Wind, water, and ice all play a part in erosion. It can be caused by natural forces or can be man-made.
What is riprap in construction?
Riprap. A riprap’s goal is to is to slow and divert the flowing water. This process uses rough, loose stone on an embankment slope to prevent erosion. Granite is typically used and ins placed about 6-8 inches wide each.
What is a terrance in a retaining wall?
Terrance. This is the process of adding in a stair-step up the slope. Each layer allows you to place plants between the steps. The idea of the Terrance is that the water won’t run off, but soak into the soil. The retaining wall can be made of timber, stone, concrete, or precast concrete block.
Why are hills and slopes important?
These added dimensions can be helpful to separate a home form a busy street, add extra privacy. However, these hills can also be susceptible to erosion and runoff that is hard to control and the damage that soil washing away can cause is devastating.

How to prevent erosion of a slope?
One of the simplest ways to do this is to create open ditches or drains by simply digging along the slope at regular intervals. Use of pipes and gutters is also very effective, and work just as well as natural drains when designed and installed properly.
How to stop erosion on steep slopes?
If this is the case, you should consider building terraces to help slow down erosion as the vegetation takes hold. Terraces can be made out of anything, from wood to concrete blocks to bio-mechanical solutions like the C ascadia Green Wall that uses Filter Soxx with natural mulch/seed filling and geogrid for structural stability. The beds that are created by the terraces can then be used to plant vegetation such as ornamental plants or grass.
What is compost erosion control blanket?
Compost erosion control blankets act similarly to mulch products but provide organic nutrients that promote vegetation growth, even in areas where germination, moisture management and irrigation could be challenging.
How to stop soil erosion?
Plant Grass and Shrubs. Grass and shrubs are very effective at stopping soil erosion. This is primarily because plant roots tend to hold soil together, making it harder to erode. The leaves of the plants also help to reduce the velocity of raindrops falling on the ground, making it harder for them to dislodge the soil and erode it.
Does soil stay put on steep slopes?
For the most part, soil will stay put. However, on steep slopes and embankments, there is the elevated risk of erosion. It is essential to put as much effort as possible into actions that will stop the soil from washing away. This is because not only could this make the area that has been eroded barren, but it could also adversely affect water ...
How to stop erosion on a slope?
Another method for stopping slope erosion is to build terraces on the slope. By building terraces, you create level areas of ground down the slope with the use of retaining walls. The terrace will have the appearance of large steps going up the slope.
How to stabilize soil on a slope?
One of the easiest ways to limit erosion and stabilize the soil on the slope is by planting vegetation on the slope. Almost anything will help. You can plant trees, shrubs, grass, and ground cover plants. The roots of the plants help to hold the soil in place, so that when it does rain, not as much is washed down the slope.
What causes erosion on a hill?
Soil erosion on a slope or a hill is a natural phenomenon caused by the pressure of water draining down the slope and pushing against the soil. Trying to stop it may seem like trying to hold back the sea, but it actually can be done effectively.
How to strip landscaping?
An effective practice is to alternate rows of beds and rows of grass. If you do plant grass, make sure it is accessible by a lawnmower or it could get out of hand. Also, make the rows as level as possible, as this will have the greatest effect on stabilizing the slope.
What materials are used for retaining walls?
You can use a variety of materials for the retaining walls, including stones, bricks, landscaping timbers, and concrete. Because building terraces is labor intensive, it may be better to spread the project over several years or hire a professional.
How to divert water from a slope?
You can do this by digging channels to carry the water flow, or you can use pipes to direct the water. First, you must observe the path of the water during the rainy season. By knowing the way the water naturally flows, it will be easier to divert it. Mark the path the water takes so it will be easy to find when the time comes; don't trust your memory. You can use stakes or flags to mark the path.
Can you hold back erosion?

Before you cultivate your land or undertake any construction projects, assess your land for erosion potential. Checking vegetation, drainage, and considering climate will all help you avoid any problems with erosion later on.
How to restore flat land to its natural state?
You’ll start with temporary groundcover to hold the soil together, then gradually move on to adding native plants that will restore the land to its naturally healthy state.
What is erosion in science?
Know about erosion. Erosion is a natural process that loosens and sweeps away soil and rock material. It is caused either by geological or man-made factors.
What is the term for the top layer of soil that is swept away by natural or man-made forces?
This article has been viewed 402,832 times. Learn more... Erosion occurs when the top layer of soil is swept away by natural or man-made forces, making it extremely difficult to grow any vegetation on the site. Erosion can turn once healthy, vibrant land into arid, lifeless terrain and further cause landslides and mudslides.
How to stop erosion in a gully?
Break up channels. A channel is a spot where running water cuts into the soil and forms a rut. By filling the channel with compost or manure, you will help prevent further erosion. If a channel increases in size with each rain, it can eventually form a gully, which is harder to address.
What are the two major classifications of erosion?
Geological erosion and man-made erosion are the two major classifications of erosion. [2] There are two major classifications of erosion: (1) geological erosion, and (2) man-made erosion. Geological erosion occurs naturally when the distribution of soils is disturbed in some manner, either through soil formation or soil removal. [3] ...
How does strategic rock placement help with erosion?
Strategic rock placement can help you maintain the positive, restorative effects of other erosion control methods by keeping soil protected from events like flash floods, high winds, and harsh, extreme sunlight.
Why use riprap on slopes?
Resloping your sloped areas with riprap is especially useful if you’re trying to re-establish vegetation, smooth out erosion gullies, and trap eroding soil more effectively and naturally.
What is the best slope for a rock terrace?
Rock terraces are better suited for properties where the slope incline is at least 30%. Make sure to stack terraces so that they’re slightly perpendicular to the hillside as this will allow for some run-off without eroding the soil of its nutrients.
Why is cobblestone used in driveways?
You may think cobblestone exists to make driveways and streets more aesthetically pleasing, but this type of stone has its use in erosion control. Its round-edged, interlocking configuration makes it the ideal rock type for allowing a natural stream of water, nutrients, and root systems to move through the soil unobstructed.
Why are rocks absorbent?
Most natural stones and rock types are absorbent because they’re porous and allow liquids to sink through. Non-absorbent stone might seem counterintuitive in this light, but it has its use.
What is the best way to bring soil fertility back up?
If you need to bring your soil’s fertility levels back up, erosion control blankets are a better choice. Your choice of the right rock type for your property depends on its physical orientation, and there are multiple options, each with a specific purpose.
How to build a retaining wall?
To build these retaining walls and place the rock, you’ll need to cut into the slope and create a level ground above and below the wall.
What is the best way to control erosion?
Plastic. Plastic is for bags, soda bottles, and children's toys. If you stuck those items on the hillside they would be about as attractive and effective for erosion control. (After a few years the plastic 'weed barrier', 'mulch' or 'erosion matting' has curled and is sticking up in amongst the weeds.)
How to make a slope into a storm drain?
The resulting steeper slopes can be readily accessed from the path below. Make sure you account for runoff across the slope on the path. The path can become a storm drain if it runs across the slope at an angle. That is ok, as long as you put some rocks and boulders along the inside of the path to slow the water and stop erosion as the water blasts across the slope in a down pour.
Why is mulch important?
The type of mulch, placed on top of the ground, is very important in the management of a slope susceptible to erosion. See the mulch page for appropriate types of mulch to us e. If you use the wrong type of mulch the plants will not grow very well, weeds could be introduced, and erosion could be increased!
What is the goal of feeding runoff off a slope onto your neighbor's slope?
The goal is to control the runoff in a way that does not cause further problems. Feeding the runoff off a slope onto your neighbor's slope is not drainage or damage control, it's a lawsuit.
How long does it take for a rock to drain?
Fill that hole you dug with water and time how long it takes for the water to drain. An hour or less is good; if 2-3 days, then the slope has a problem. Dig around some more and see if there's rock under it. Have a soil analysis down and look for sodium, boron or high calcium.
Why aren't ice plants appropriate for erosion?
These plants are not appropriate to control erosion on a slope because 1) they are alien plants and not part of our natural plant community, 2) they have very shallow roots. 3) they are heavy.
What happens to slopes after a fire?
Seeding slopes after a fire or grading does nothing but destroy the ecosystem for perpetuity. Bare, grass-covered or ice plant-covered slopes commonly load up to field capacity (and beyond), while slopes covered with a mix of native shrubs and trees and perennials rarely do (Patric).
