  • GIS-based modelling for the estimation of municipal solid waste generation and collection

    In the present paper, an innovative model for the estimation of municipal solid waste generation and collection is proposed. This model is part of an extended solid waste management system and uses a spatial Geodatabase, integrated in a GIS environment. It takes into consideration several parameters of waste generation, such as population density, commercial activities, road characteristics and ...

  • Using GIS for emergency management: a case study during the 2002 and 2003 flooding in south-east France

    Emergency management has always required tools to get geographic information from the affected area. The objectives are to have a general view of the theatre of operations with its geographic characteristics, troop's location, roads and railways, and fighting location. The emergency management of natural hazards is specific because it is necessary to evaluate the appropriate number of emergency ...

  • Innovative methodology of demand responsive approach for large-scale water supply and sewerage/on-site sanitation projects in developing countries using participatory GIS with high resolution satellite imagery

    International discussions on the demand responsive approach (DRA) started in the mid-1990s because past supply-driven approaches had led to the failure of many water supply and sewerage/on-site sanitation (WS&S/OS) projects in developing countries (DCs). DRA has already been adopted in many WS&S/OS projects targeting a certain rural or poor urban area(s) by using various demand assessment ...

  • 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 ...

  • Flood occurrence hazard forecasting based on geographical information system

    The application of Geographical Information system (GIS) in modeling flood and its prediction in catchments offers considerable potential. Several examples illustrate simple GIS techniques to produce flood hazard indices or its zonation using hydrologic-type models. Existing flood models can also be loosely coupled to a GIS, such as the HMS (Hydrological Modeling System) model. Forethermore, ...
