The type of facilities goes from uncontrolled dumpsites to highly engineered facilities with leachate and gas management.
Urban infrastructure is a multifaceted concept that goes beyond a set of engineered facilities, utilities, and systems.
Sanitary landfills are not dumps; they are carefully planned and engineered facilities designed to control leachate and methane and minimize the risk of land pollution from solid-waste disposal.
This information and understanding will assist in identifying opportunities and guiding the development of engineered facilities for the sequestration of CO2 by means of mineral carbonation.
Practicing engineers can use this model for approximate estimation of the tensile strength of unsaturated granular soils without experiments and for precise design or analysis of most engineered facilities relying on the unsaturated granular soils in the vadose zone.
Through a series of experimentation over years, an innovative cultivation system has been developed recently in China where clustered solar-energy, plastic-roofed, engineered facilities are built on nonarable to produce fresh vegetables year round, season after season.
Landfills receiving a mix of waste, including organics, have developed dramatically over the last 3 4 decades; from open dumps to engineered facilities with extensive controls on leachate and gas.
The performance assessment of civil engineering structures and systems subjected to earthquakes must account for the substantial uncertainties in the seismic demands and the nonlinear behavioral characteristics and capacities of complex engineered facilities.
It is widely recognized that the most rational way of assessing and reducing the risks of engineered facilities and infrastructures subject to natural and man-made phenomena, both in the design of new facilities and in the rehabilitation or retrofitting of existing ones, is Performance-Based Design, usually indicated by the acronym PBD (but a better term would be "Performance-Based Engineering").
While it is recognized that resilience of a community must be supported by individual buildings and engineered facilities, the relation between community resilience goals and minimum performance criteria of individual structures enabling such goals through engineering practices does not yet exist.
