Flood management methods can be structural or non-structural: Structural flood management (i.e: flood control) is the reduction of the effects of a flood using physical solutions, such as reservoirs, levees, dredging and diversions. Non-structural flood management includes land-use planning, advanced
For a flood risk assessment to be written, information is needed concerning the existing and proposed developments, the Environment Agency modeled flood levels and topographic levels on site. At its most simple (and cheapest) level an FRA can provide an indication of whether a development will be allowed to take place at a site.
While flood control aims mainly on reducing or preventing the negative effects of floods, IFM aims on reducing the overall risk by means of land and water resources management with the goal of maximizing the benefits from the use of flood plains and minimizing the damage and loss of life due to flooding in a sustainable manner.
Flood flows in urban environments have been investigated relatively recently despite many centuries of flood events. [20] Some researchers mentioned the storage effect in urban areas. Several studies looked into the flow patterns and redistribution in streets during storm events and the implication in terms of flood modelling. [21]
The project design flood peak discharges remained unchanged." [1] Once the project design flood was developed, flow rates at critical points are used to determine how high levees need to be, how deep the dredging needs to be, and the flowrates at which flood control structures need to be used.
The term disaster risk management (DRM) is often used in the same context and to mean much the same thing. That is a systematic approach to identifying, assessing, and reducing risks associated with hazards and human activities. DRM is more properly applied to the operational aspects of DRR: the practical implementation of DRR initiatives. [9]
Project NOAH (Nationwide Operational Assessment of Hazard) is the Philippines' primary disaster risk reduction and management program. Managed by the University of the Philippines , it was initially administered by the Department of Science and Technology (DOST) from 2012 to 2017.
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain ...
