To evaluate how the erosion and runoff process' work, one would conduct a Rainfall Simulation. Doing a simulation, one comes to comprehend various types of land management and the infiltration that occurs according to how the land is used. The land used in this lab consists of thick cover and low cover. The plots are mainly covered in grass and were dry before the simulation took place. At about 3 o'clock in the afternoon on a very windy day at the Texas A&M field the simulation began. The soil was dry when beginning the lab and samples were taken to find out its infiltration rate. The area of the plot was 3 meters squared and the infiltration rate was taken from there. This rain simulation lab is specifically conducted to gain experience in learning about the infiltration process and sediment yield. Knowing these specific types of objectives one can then fee off of results of this lab to make their land healthy.
The information for the Rainfall Simulation lab can be found on pages 11-1 through 12-2 of the Spring 2002 Range and Forest Watershed Management Lab Manual.
The rainfall simulation lab began with two groups of students who each had a plot and
These percentages were pure estimation that determined what the chances were of a raindrop actually hitting a certain type of vegetation cover rather than going straight into the soil.
To conclude the lab, clipping of the vegetation for its weight and separation is necessary. Using garden scissors and clipping all forbs, grass, and picking up litter they are then all separated and placed in bags.
