This study focuses on evolving an integrated water management plan (IWMP) for Shimla City (erstwhile summer capital of British India). Presently it is the state capital of Himachal Pradesh. Total water demand (2014) is 58.46 million litres per day (MLD) against system capacity of 54.54 MLD. The present deficit of 3.92 MLD (2014) may amplify to 59.01 MLD in 2051. Resource assessment in the ...

Giardiasis is the most commonly reported intestinal parasitic infection in the United States. Outbreak investigations have implicated poorly maintained private wells, and hypothesized a role for wastewater systems in giardiasis transmission. Surveillance data consistently show geographic variability in reported giardiasis incidence. We explored county-level associations between giardiasis ...

Quantifying groundwater availability depends upon sound methods and the use of integrated models. To determine availability or sustainable yield, the influence of scientific uncertainty from key sources, such as anthropogenic recharge, must be considered. This study evaluates uncertainty in recharge interpretations on the modeled available water balance for an urban case in Texas, USA. Analyses ...

Assessment of pollution risk requires the assimilation of spatio-temporally variable data on water quality parameters. This paper describes a GIS user-interface program coupled with a water quality index (WQI) model that was developed and built to assess water quality in the Sg. Buloh river basin. Fifty-two water sampling stations were selected for this study, and the WQI model considers ...

European Centre for Disease Prevention and Control (ECDC) commissioned a team of scientists to assess the change in vulnerability of EU Member States to infectious disease over the next fifty years as a result of projected changes in climate. Vose lead the modelling part of the project, developing a range of indices that allowed ‘heat maps’ to be produced showing regions down to ...

During the formation of a frazil-generated ice cover, ice bridging can occur along sections of rivers that are geomorphologically suited (e.g. very sinuous, narrowing channel width, low gradient bed slope) to arrest the flow of ice pans. Bridging may occur at several locations along the river independently from one another with separate ice cover formations occurring simultaneously. ...

A methodology for indexing river environmental condition was developed and applied to 269 subsections of national rivers located in the Republic of Korea, based on a river management perspective. The resulting index has been called the River Environment Index (REI). To develop the methodology, a total of 32 factors related to a river's environment were initially investigated, from which ...

This paper introduces Japan's institutional efforts on city–level information systems and geospatial databases in various historical phases in the context of urban planning and e–government. The study of urban planning information systems and geospatial data building has been led by the national government from the beginning since 1970s. However, single purpose GISs, such as UIS in ...

This paper describes and demonstrates the integration of two geospatial decision–support systems for natural–hazard risk assessment and management. Hazus is a risk–assessment tool developed by the Federal Emergency Management Agency to identify risks and estimate the severity of risk from natural hazards. The Land Use Portfolio Model (LUPM) is a risk–management tool ...

There is a large class of modeling problems where the complexity of the underlying phenomena is overwhelming and hence the accuracy of mathematical models is limited. Our approach to this class of problems is to design frameworks that bring together physically based and data-driven models, and incorporate the tacit knowledge of experts by providing visual exploration and feedback capabilities. ...

Uncontrolled dissemination of geospatial data may have grave implications on national security and personal privacy. Geospatial data can be considered sensitive based on attributes such as the location, resolution and the time of capture, etc. As such, authorisations associated with this data also possess spatial and temporal attributes. The main contribution of this paper is to improve the ...

Irregular patterns of precipitations from temporal as well as spatial perspectives not only cause destructions but also waste surface water resources. Hence, controlling surface water and leading the flood to underground stores improve the efficiency of water usage. Selecting appropriate sites for optimal use of water floods is ...

In modern time, the ability to explore the oceans has been inextricably linked to the evolution and development of marine technology. Over the past 20 years, the steady evolution of hardware design has resulted in increased sampling rates, data volumes and resolutions. Furthermore, improvements in the manufacturing of marine technology have decreased the overall cost of hardware which has ...

This article approaches sustainability study via geospatial analysis. By mapping two sustainability datasets (Ecological Footprint, 2003 and Environmental Sustainability Index, 2005) the article first assesses the current state of sustainable development world wide. The incompatible pictures presented by the two datasets imply their conflicting views on sustainability. To comprehend the ...

 ABSTRACT The Massachusetts Department of Conservation and Recreation (DCR) is a state agency which owns and maintains parks, conservation and watershed land, and roadways. They are regulated as a non-traditional MS4 stormwater municipality under the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II program. To satisfy the ...

 The CAP reform by decoupling subsidies from production levels and liking them to the protection of the environment is promoting a cleaner agriculture and a more sustainable use of resources. Agricultural subsidies are now linked to application of statutory minimum requirements (SMR) and cross compliance. Farmers willing to go beyond SMR can get additional payments through Rural Development ...

Technical Area 21 (TA-21) is a former processing area located on a 0.5 square mile mesa top at Los Alamos National Laboratory (LANL), New Mexico. A series of threedimensional (3D) geospatial models were developed to support ongoing and future environmental restoration activities. Mining of lithologic, geophysical, infrastructure, and analytical data sets was completed to construct 3D site ...
