Usually large rocks are placed at the outlet of a culvert to prevent the concentrated outflow of water from eroding and moving sediment and delivering the sediment to larger creeks or undercutting the road.

Weathering and erosion cause both physical and monetary damage to property and environmental areas such as buildings and topsoil.
A type of metric symbol, inlet/outlet
Erosion increases when there is a flood and when land is plowed and there is no cover crop that would prevent wind erosion.
The four types or mechanisms of erosion are rill erosion, gully erosion, stream bank erosion, and sheet erosion. In sheet erosion a thin layer of the surface is removed. In rill erosion, small rivulets of running water gather together and cut small channels. In gully erosion, rills enlarge to form bigger channels too large to be removed by normal tillage. Finally, streambank erosion is the washing away of soil from banks of streams and rivers. Erosion is a natural, continuous process, but agricultural practices can speed erosion, resulting in lost soil, lost soil fertility, air pollution, and water pollution. Wind and water are the main agents that move soil.

The fox is in the culvert. The culvert is blocked at the other end.
" Step 1 Dig out the drainage ditch. Broaden the ditch to roughly twice the width of the culvert and angle the sides of the ditch. Dig about six inches out of the bottom, for the entire length of the culvert. Step 2 Fill the bottom six inches with gravel, maintaining the original level of the drainage ditch. The gravel will allow the culvert to settle evenly and allow for better drainage in the event that water flows around the culvert. Step 3 Place the culvert in the ditch, centering it in the gravel. There should be about one foot of excess length on each end of the culvert. Step 4 Fill in the sides next to the culvert with dirt, tamping the dirt down at regular intervals. Keep the culvert centered in the ditch while doing this; a crooked culvert will cause erosion on the walls of the ditch. Step 5 Cover the top of the culvert. Cover with at least 12 inches of dirt and tamp down well. Cover this with gravel to avoid erosion. Step 6 Tamp the sides of the fill down tightly, making sure they are angled in towards the top. Regular maintenance will be needed to keep the walls from eroding away." and that how u install it
Corrugate Metal Pipe Culvert.
The Big Culvert was created in 1870.
Erosion control is the term used in the practice of preventing or controlling wind and water erosion in agriculture, land development and construction.
Mechanical erosion control measures are implemented to minimize onsite and offsite impacts of these activities, as well as to rehabilitate degraded lands. Often, mechanical erosion controls are applied in combination with vegetative erosion control techniques.
False. Erosion control should begin before the first evidence of erosion. When building bridges over waterways, construction contractors are already devising ways to control erosion so the bridge does not fall into the water later on.
False
Sheet erosion can be prevented by mainting vegetation in the area
Erosion is a natural process. Humans contribute to erosion when they clear an area of plants. Plants help to keep the soil in place through their roots. Humans can help to control erosion by planting hillsides and slopes with erosion control plants.
There is enough room to put a navigable culvert through this side.
