MULTI-CRITERIA EVALUATION (MCE) OF AQUIFER VULNERABILITY AND PROTECTIVE CAPACITY MAPPING USING AQUIFER VULNERABILITY INDEX (AVI) AND GOD MODELS: A CASE STUDY OF FUPRE
Abstract
This project work conducted an in-depth evaluation of aquifer vulnerability and protective capacity at the Federal University of Petroleum Resources, Effurun (FUPRE) using the Aquifer Vulnerability Index (AVI) and Geomorphology, Output, and DRASTIC (GOD) models. The study aimed to assess the susceptibility of the aquifer system to contamination and identify the natural defenses that can mitigate pollution risks. The evaluation revealed a complex landscape of vulnerability and resilience, with areas exhibiting varying levels of vulnerability and protective capacity.
The AVI mapping Identified regions with moderate vulnerability, highlighting potential risks of contamination from human activities such as agriculture and urban development. These findings underscored the need for targeted management strategies to safeguard water quality and protect the aquifer system from pollution sources. Conversely, the GOD model mapping predominantly showed low vulnerability index areas with minimal instances of moderate vulnerability, indicating the aquifer’s natural defenses against pollutants.
The combined assessment from the AVI and GOD models provided a comprehensive understanding of aquifer health and resilience, enabling stakeholders to prioritize conservation efforts and implement effective management strategies. Recommendations were proposed to enhance monitoring, promote stakeholder engagement, leverage natural protective capacities, and pursue research and innovation to support sustainable water management practices.
Overall, this project work highlighted the importance of proactive management, stakeholder collaboration, and data-driven decision-making to protect the aquifer system, maintain water quality, and ensure sustainable water resource management in the FUPRE region. The findings and recommendations presented in this study contribute to the conservation of the aquifer system and provide valuable insights for future research and management initiatives aimed at preserving water resources for current and future generations.
