Abstract
This MS thesis entails an experimental and analytical study of a slope failure that occurred in the city of Mayagüez after a heavy storm on June, 2005. The slope failure case history is considered a representative event of the recurring shallow landslides that often occur in residual soil slopes of Western Puerto Rico. The experimental component of this work involved field reconnaissance, surveying of the failed slope, geotechnical drilling and testing, soil sampling, laboratory testing, long term field monitoring of rainfall, soil moisture, and soil suction. The study also included laboratory tests to evaluate the soil-water characteristic curve. The research also included an analytical component to investigate the triggering mechanism of the slope failure.

Esta tesis de maestría trata de un estudio experimental y analítico de un talud fallado en la ciudad de Mayagüez, PR luego de una lluvia fuerte en junio del 2005. El deslizamiento se considera como un evento representativo de los deslizamientos superficiales que ocurren frecuentemente en pendientes con suelos residuales en el oeste de Puerto Rico. El componente experimental de este trabajo envolvió reconocimiento de campo, agrimensura del talud fallado, muestreo, pruebas de laboratorio, monitoreo a largo plazo de lluvia, succión, y contenido de humedad. La investigación también incluyó un componente analítico para investigar el mecanismo de falla del talud.
