Levee body seepage: a refinement of an expeditious procedure for fragility curves and vulnerability diagrams’ assessment

Extensive flooding can be the result of levee system failures most frequently caused by the piping process due to seepage. The proper description of the seepage line is affected by the difficulty of estimating the hydraulic parameters, mainly the soil hydraulic conductivity. Therefore, the development of simple methods for a quick analysis of extended levee systems is fundamental to identify ...

Position on Decision ‐/CP.20 Lima call for climate action and its Annex on elements for a draft negotiating text

About one quarter of all human induced emissions come from agriculture, forestry and other land use (AFOLU). A disproportional large part of these AFOLU emissions come from organic soils (peatlands) drained for agriculture, grazing, forestry or mining. This briefing provides recommendations to ensure that a new climate agreement provides strong incentives to reduce emissions from drained ...

NextGen GIS and the Environmental Database

Next Generation (NextGen) Geospatial Information System (GIS) and U.S. Department of Energy (DOE) Cold War legacy sites environmental records—spanning nearly 40 years—in the Environmental Database, are managed by the DOE Office of Legacy Management (LM). As key LM assets, these records must be managed and maintained efficiently and effectively. There are over 16 different applications ...

A river environment index for Korean national rivers: rationale, methods and application

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 ...

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 ...

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 ...

Land assessment for flood spreading site selection using geospatial information system

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 one of the most important factors in recharging underground water ...

Human-GIS interaction issues in crisis response

Geospatial information systems (GIS) provide a central infrastructure for computer supported crisis management in terms of database, analytical models and visualisation tools, but the user interfaces of such systems are still hard to use, and do not address the special needs of crisis managers who often work in teams and make judgements and decisions under stress. This paper articulates the ...
