6. When did the most leakage occur through Layer 5? How much?
7. How do these two layers differ with regard to type and leakage values generated?
8. Based on the results of this simulation, is the design of this landfill acceptable from an
environmental standpoint? Discuss.

Location Two: Miami, FL

Step 2: Entering Weather Data
A. Precipitation Data:
● Press <Enter> to select the highlighted default option for the precipitation data
● Use the arrows on the keyboard to select Florida

Miami

C. Solar Radiation Data:
● Use the right arrow again to select the Synthetic solar radiation data
● Select Florida and then Miami

D. Evapotranspiration Data:
● Select Florida, then Miami and press Enter to enter these default data
● Specify an evaporation zone depth of 10 by scrolling to that cell and typing in the
value
● Also specify a maximum leaf area index of 4.2
● SAVE the changes that you have made by pressing F10 and Y (yes) for each of the menu
items — type your name into the “file” cells

Step 3: Entering the Soil Data
● Press 2 on the main menu screen to begin editing the Soil Data
● Press Page Down to create new
● Enter 40 acres for the landfill area and change the area able to be drained to 95% and
leave the latter box with the default value by pressing Page Down
● Next you must enter data regarding the layer and soil types for a total of three layers

First Layer:
● Enter 2 for the first layer type, a leachate recovery layer
● Press <Enter> to specify layer thickness and enter 20 in.
● Press F6 to find the default soil data provided by the HELP program
● Scroll down to Municipal Waste (900pcy) and press Enter — this will add the default
data to your table
● Next scroll over (press Enter) and enter a value of 0.5 for the initial moisture (vol/vol)

Second Layer:
● Enter 4 for the second layer type, a geomembrane liner
● Enter a layer thickness of 8 in.
