Application of GIS and AHP Analysis for the Delineation of Potential Groundwater Bearing Zones in Fractured Rock Aquifers
Birriel Christian, Gustavo A. (Polytechnic University of Puerto Rico, 2017)Groundwater extraction accounts for around 29% of Puerto Rico’s water demand. About 50% of the withdrawn water from aquifers serves the needs of “Non PRASA” communities mainly located in the central province of the ... -
Assessment of Geomorphic Characteristics and Analysis at the Existing Bridge Site in Puerto Rico
Moreno Isaac, Emanuel (Polytechnic University of Puerto Rico, 2023)The scour on bridges is considered one of the main reasons for bridge failures. Scour is the consequence of the erosion action that is caused by the water flow, which at the same time excavates and carries away material ... -
Case Study Through the Application of Value Engineering – Tunnel Construction
Ortiz Reyes, José L. (Polytechnic University of Puerto Rico, 2021)Value engineering is an effective approach used by many industries that aims to analyze a product or project to optimize it while reducing costs. VE does not just focus on cost reduction; its purpose is functional ... -
Change in the Precipitation Parameter Source and its Effect in Previously Designed Structures
Colón Collazo, Orlando J. (Polytechnic University of Puerto Rico, 2020)The impact of any development brings with it a series of changes to the environment that must be mitigated; thus, Hydrologic and Hydraulic Studies become necessary to bring solution at the design process. The ... -
