Gravity Anomaly Over a Tunnel

This JavaScript application will produce synthetic gravity anomalies over a buried tunnel. You can use this script to design a gravity survey for the project described in the request for bid. The red circle in the graph below represents a tunnel with a specific radius, depth of burial, and density contrast, rho. The depth of burial of the tunnel can be varied by clicking with the up and down arrow buttons or pressing the up and down arrow keys on your keyboard. In addition to parameters that control the tunnel, you can also vary parameters that control gravity survey from which you will interpret observations. These parameters include the spacing between gravity readings, the number of gravity readings to be average at each station, and the expected standard deviation of the observed gravity readings.
