The North Coast Karst Aquifer System of Puerto Rico is the most productive aquifer of the island. Same characteristics that makes it highly productive, makes it vulnerable to contamination. This research assess potential ...

Este trabajo presenta una metodología basada en la aplicación de técnicas en sistemas de información geográfica (SIG) con el objeto que puedan ser utilizadas en la delineación de áreas de cabecera para ríos de Puerto Rico, ...

Red Light Running (RLR) is a potentially severe safety issue at signalized intersections. To determine the driver reaction at the end of the green period at signalized intersections, a RLR study was performed using 32 ...

This study evaluated the behavior of concrete filled FRP tubes (CFFT) subjected to moisture absorption condition. Accelerated aging by means of hygrothermal process was conducted to predict long-term mechanical behavior ...

This project consists in the analysis and design of reinforced concrete cantilever retention walls. The purpose of this analysis and design is to develop construction drawings, as shown in Apendix 3, and have them ready ...

During a seismic event, structural damage may result from the vibration of the structure in response to ground shaking at its foundation. The assessment of structural damage after a seismic event is required to identify ...

Volume Delay Functions (VDF) are formulas developed to describe the functional relationship between travel time and traffic flow in a travel demand model considering the available capacity of the facility. VDF’s are the ...

Highway designers and transportation officials in Puerto Rico are beginning to consider the design and installation of modern roundabouts as an alternative to traditional at-grade intersections. The modern roundabout has ...

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 ...

This thesis presents the analysis of the structural behavior of steel oil storage tanks exposed to fire. This study focuses on determining the deformed configurations and the critical buckling temperatures of storage tanks ...
