Statistical approaches and hydrochemical modelling of groundwater system in a small tropical island
The aquifer of Manukan Island of Borneo, Malaysia had been found to be affected by seawater intrusion associated with excessive groundwater exploitation. This research attempted to characterize the chemistry of an impacted zone in the island using factor analysis (FA), cluster analysis (CA) and a hydrochemical model package (PHREEQC). The factor scores were used to plot the spatial map and to ...

White paper on Willowstick technology used for mapping and modeling groundwater systems
1.0 Introduction Willowstick Technology (the “Technology”) delineates and characterizes subsurface aqueous systems in complex hydrogeologic settings. It has consistently proven valuable in: 1) the diagnosis of seepage through earthen dams and levees; 2) characterizing groundwater infiltration into surface and subsurface mines; 3) tracking pollution plumes influenced by groundwater ...

Integrated fuzzy framework to incorporate uncertainty in risk management
Integrated Fuzzy Relation Analysis (IFRA) model is proposed for risk assessment involving multiple criteria. The model is an integrated view on uncertainty techniques based on multi-valued mappings, fuzzy relations and fuzzy analytical hierarchical process. Integration of system simulation and risk analysis using fuzzy approach allowed incorporating system modelling uncertainty and subjective ...

Integration of Subsurface Data Management and GIS to Facilitate Model Calibration
Abstract The development of numerical codes, as well as pre- and post-processors to support these codes, has made the discipline of groundwater modelling increasingly more automated and efficient. The value of such modelling is reliant on the site-specific data used to build and calibrate the models. The integration of EarthSoft's EQuISÒ Geology and any of several popular modelling environments ...

Integrating GIS and Groundwater Modeling Technologies for SWAPP Development
Groundwater Modeling and GIS Technologies: Powerful Tools for Data Integration and Analysis Groundwater modeling and Geographic Information System (GIS) technologies are useful tools for developing a Source Water Assessment and Protection Plan (SWAPP) to assist planners in protecting groundwater ...

Ranking of conceptualized groundwater models based on model information criteria
Modelers typically test alternative conceptualizations of a groundwater system because the ‘true’ hydrogeological model of the system is unknown, and the observed data are limited. This study elaborates on how to rank different conceptualizations of a groundwater system by using selection techniques and criteria that make a balance between complexity and accuracy of models. ...

Preliminary assessment of the impacts of deep foundations and land reclamation on groundwater flow in a coastal area in Hong Kong, China
Many coastal areas have been intensively urbanized because people living and working on or near coastlines are increasing. Land reclamation from the sea and high-rise buildings are common approaches to satisfying the growing needs for more housing and other land use. Coastal areas are usually the ultimate discharge zones of groundwater systems. Using a coastal area in Hong Kong as a case study, ...

Sustainability of Arizona’s few remaining perennial streams.
Mother Nature made water simple. In general, water comprises a continuum in whatever phase or phases it may occur. If you take some here, you have less somewhere else. Arizona law does not readily account for this simple concept; rather it arbitrarily divides water into different classes to be regulated as if the classes were somehow distinct and separable. This creation of different classes of ...

Homeland Security for Drinking Water Supplies
As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...
