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 ...

New Jersey Uses GIS, EQuIS to Collect Site Remediation Data

Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the ...

Geographic information systems (GIS) for participation: the future of environmental GIS?

The conventional uses of geographic information systems (GIS) in environmental management have been criticized for being undemocratic and avoiding the social dimension of these issues. To address these criticisms, new participatory approaches are being developed by the GIS community. These new techniques involve the integration of conventional spatial data and mental maps showing communities' (or ...

Data Sharing – a Case of Shared Databases and Community Use of On-Line GIS Support Systems

Data management is becoming increasingly simple and complex at the same time. The challenge is to effectively use the increasing number of tools available to manage increasing amounts of environmental information for purposes of data capture, analysis, display, sharing and storage. Government is no longer the main collector and provider of data. Community groups possess vast amounts of data ...

An approach to quantifying rainwater harvesting potential using imagery, geographic information systems (GIS) and LiDAR data

Geographic Information Systems (GIS) software is used to analyze rainwater harvesting potential in Escambia County, Florida, USA. The approach presented can be replicated using LiDAR data, and the infrared spectrum of National Agriculture Imagery Program (NAIP) imagery. GIS surface maps are analyzed in combination with local utility consumption data to determine potential reductions in potable ...

A GIS-based methodology to delineate aquifer recharge areas

A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

Mapping the results of mobile network monitoring: a GIS solution

Most of us are familiar with the 'can you hear me now' commercial - a spectacled technician from a major wireless carrier moves about with a dedicated team testing the voice clarity of the network. Geographic information system (GIS) technology (Foote and Lynch, 2011), together with the use of existing data collection hardware, allows analysts to map results of mobile networks both accurately and ...

Application of GIS to Plan Long-Range Water Supply Facilities by Linking Land Use and Water Billing Data of City of Cape Coral in Southwest Florida

This paper describes the application of a land use based approach to prepare a long-range forecast of water supply demand for the city of Cape Coral in southwest Florida. There are two common approaches to forecast water demand: (1) use of population projections; and (2) analysis of future land use planning. The South Florida Water Management District (SFWMD), as required in 2002 Legislation, has ...

Risk assessment and GIS in natural hazards: issues in the application of HAZUS

The use of HAZUS is being encouraged by FEMA (Federal Emergency Management Agency) as jurisdictions are being forced, by regulation, to perform more sophisticated planning and risk assessment. HAZUS is a multi-hazard risk assessment tool that is available to public sector free of charge, and runs on the ArcGIS platform. The promotion, however, does not mean that HAZUS is a wonder drug, one that ...

Spatial analysis of water quality using a combination of GIS and statistical software

GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between ...

Study of water-table behaviour for the Indian Punjab using GIS

The state of Punjab (India) has witnessed a spectacular increase in agricultural production in the last few decades. This has been possible due to high use of fertilizers, good quality seeds and increased use of water resources. This increased demand of water resources has resulted in extensive use of groundwater in the central districts of the state and surface water (canals) in South-West ...

A GIS-based assessment of the Byzantine water supply system of Constantinople

Despite the extensive archaeological surveys carried out in the last decades, little attention has been paid to one of the longest water supply systems of ancient times – the Byzantine water infrastructure which fed Constantinople from the mid-late fourth century ad. This work uses modern satellite terrain data and Global Positioning System (GPS) data to assess this system and provide an ...
