hThere are countless smuggler tunnels under the US-Mexican border. The tunnels are primarily located between Arizona and the Pacific Coast. The reason for this is because the western section of the US-Mexican border has many more towns and cities which lie up next to each other. To the east, New Mexico to the Gulf of Mexico, there are some border meeting points like Brownsville-Matamoros and El Paso-Ciudad Juarez, but these junctions are few and far between with desert separating towns by miles. What is also a greater hinder though is physical obstacles like the Rio Grande.
These tunnels are mostly used for drug smuggling but some are also used for human trafficking. This makes them a law enforcement concern. Geotechnology is playing a part in curbing use of these tunnels. Popular Mechanics has a feature on how the types of geotechnology being used. Everything from "standard" ground penetrating radar to measuring oh so slight changes in Earth's magnetic field can be utilized. The neatest one involves cosmic rays- it is so easy a 12 year old did it!

El Paso river? Do you mean the Riio Grande or Rio Bravo del Norte as it is called in Mexico?
