By when? a streamlined approach to prioritizing and stabilizing creek crossings

ABSTRACT Colorado Springs Utilities (Springs Utilities) owns and operates over 1,500 miles of sanitary sewer pipelines throughout several watersheds in Colorado Springs, Colorado. Several of these pipeline segments cross or run parallel to major stream segments or minor drainage ways. In the summer of 2005, Springs Utilities embarked upon an aggressive program to identify pipeline segments ...

Understanding critical infrastructure failure: examining the experience of Biloxi and Gulfport, Mississippi after Hurricane Katrina

This article examines disaster recovery and resilience issues following a major hurricane. Two coastal communities were chosen for study following Hurricane Katrina in order to explore the issues in measuring and evaluating recovery and resilience. The communities were Biloxi and Gulfport, Mississippi. A mix of data sources was employed to determine effects on critical infrastructure on a ...

Integrating Bayesian networks and geographic information systems: Good practice examples

Bayesian networks (BNs) are becoming increasingly common in problems with spatial aspects. The degree of spatial involvement may range from spatial mapping of BN outputs based on nodes in the BN that explicitly involve geographic features, to integration of different networks based on geographic information. In these situations, it is useful to consider how geographic information systems (GISs) ...

Climate change case study

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 ...

Water recreation and illness severity

The health endpoint of prior studies of water recreation has been the occurrence of gastrointestinal (GI) illness. This dichotomous measure fails to take into account the range of symptom severity among those with GI illness, and those who develop GI symptoms but who do not satisfy the definition of GI illness. Data from two US cohort studies were used to assess use of ordinal and ...

Automating drainage direction and physiographic inputs to the CEQUEAU hydrological model: sensitivity testing on the lower Saint John River watershed, Canada

CEQUEAU is a process-based hydrological model capable of simulating river flows and temperatures. Despite an active user base, no facility yet exists for the automatic assembly and input of watershed data required for flow simulations. CEQUEAU can therefore be time-consuming to implement, particularly on large (≥104 km2) watersheds. We detail a new MATLAB toolbox designed to remove this key ...

Visualisation of the characteristics of mining subsidence with the consideration of topography: a case study in China

The existing three-dimensional visualisation of mining subsidence cannot fully convey the original landscape in the mining area. By using GIS and coupling the predicted result of subsidence in different mining stages with the original elevation data, a dynamic visualisation of mining process is approached, which could reflect geomorphologic features clearly. Furthermore, it visually shows the ...

Social–spatial structure of Beijing: a spatial–temporal analysis

In the past couple of post–reform decades of rapid urban growth of Chinese cities, Beijing experienced dramatic spatial and socio–economic transformation. This study aims to examine the evolution of Beijing's social–spatial structure in the transforming process over the past 20 years. We first collect and process Beijing's socio–demographic variables at the level of ...

Measuring sporadic gastrointestinal illness associated with drinking water – an overview of methodologies

There is an increasing awareness that drinking water contributes to sporadic gastrointestinal illness (GI) in high income countries of the northern hemisphere. A literature search was conducted in order to review: (1) methods used for investigating the effects of public drinking water on GI; (2) evidence of possible dose–response relationship between sporadic GI and drinking water ...

Giving Valves a Workout

Manual valve exercising is a time-consuming process, and one that poses risks of injury to employees and damage to valves. Valve-exercising technology is designed to automate the process, so that employees do not subject themselves to the strain of turning large or stuck valves, and so that only appropriate levels of torque are applied to valves. Automationhas the added advantage of enabling easy ...

Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg

Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain ...

Adaptive response and genetic instability induced in mice in vivo by low dose-rate radiation simulating high-altitude flight conditions

The effect of a low dose-rate high Linear Energy Transfer (LET) radiation that simulates the spectral and component composition of radiation fields formed in the conditions of high-altitude flights on mice in vivo has been investigated. The dose dependence, Adaptive Response (AR) and Genetic Instability (GI) in the bone marrow of generation F1 of mice born from males irradiated under these ...

Urban planning support systems in Japan: evolutions and implications

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 ...
