Steep hillside download9/10/2023 ![]() ![]() The first thing I need to know is what kind of slope you’re working with. How to build a retaining wall on a steep slope Building a dirt retaining wall on a steep slope is one of the more difficult tasks for a home owner to do, but if you break it down into smaller easy-to-handle steps, then it should become easier. It’s tough because you have to overcome a lot of physical challenges to build one, and it’s often not easy. So let’s see how we can build a retaining wall on a slope…īuilding a retaining wall is tough. This is particularly important for hillside development (home building). Retaining walls are usually built to hold back earth and prevent it from erosion, to contain the soil in place and keep it from collapsing. Observe the amount of sediment at the bottom of each hill after the storms.A retaining wall is a structure that holds back onrushing land or water. Use the solo cup with the holes punched in the bottom to “rain” one cup of water on the first hill, then the second hill. ![]() Try to plan how to keep as much sediment on your hill. Work with your team to cover the hills with sand, then gravel. Each hill should be made out of two sticks of modeling clay. Procedure Work with your team to create two clay hills. ![]() Materials 4 bars of modeling clay – two for each “hill.” Two tin baking pans 1 cup of sand ½ cup of gravel 2 cups of water, one for each rain storm/hill 1 solo cup with 6 small holes punched in the bottom Do you think the hill with the steeper slope will have more erosion? Or will the hill with the less steep slope have more erosion? Hypothesis Use what you already know about gravity and forces.
