Landslide Barrier Experiment Outcomes

The video tutorial demonstrates a landslide test to observe the impact of barriers on preventing damage. The process involves setting up rocks and twigs, placing houses, and pouring water to simulate rain. Various barriers are constructed and tested for effectiveness in preventing sliding and damage. Observations are made on the success and failure of different setups, highlighting the importance of proper barrier construction.

What is the primary objective of the landslide test introduced in the video?

• To measure the speed of water flow

• To assess the damage caused by a landslide

• To calculate the weight of rocks

• To determine the height of the barrier

What materials were initially used to set up the landslide test?

• Sand and water

• Rocks and twigs

• Bricks and cement

• Plastic and metal

What was the purpose of tilting the setup during the experiment?

• To test the strength of the barrier

• To make the houses slide faster

• To simulate the effect of gravity

• To increase the speed of the landslide

What was added to the bottom of the setup to prevent the houses from sliding?

• A plastic sheet

• A wooden fence

• A barrier made of sticks and rocks

• A layer of sand

What was the result of the initial barrier test?

• The houses slid despite the barrier

• The barrier collapsed immediately

• The barrier was too strong to test

• The houses remained stable

What was the new strategy to prevent landslide damage in the second attempt?

• Using heavier rocks

• Constructing a barrier behind the houses

• Adding more water

• Building a taller barrier

What was the outcome of building a barrier behind the houses?

• It caused more damage to the houses

• It partially worked but houses still slid

• It successfully stopped the landslide

• It had no effect on the landslide

What was the final method used to try and prevent landslide damage?

• Using a metal fence

• Building a rock wall with sticks

• Covering the area with plastic

• Increasing the slope angle

What was the main challenge faced with the rock wall method?

• The wall was too short

• The ground was too wet

• The wall was too heavy

• The ground was too dry

What was the overall conclusion of the landslide experiment?

• Only natural barriers work

• Properly constructed barriers can reduce damage

• Barriers are ineffective against landslides

• Landslides cannot be prevented
