What are non-structural mitigation measures for tsunami?
Non-structural mitigation measures for tsunamis include early warning systems, community education and preparedness programs, land use planning and zoning regulations to restrict development in high-risk areas, vegetation buffers such as mangroves to reduce wave energy, and building codes that require structures to be designed to resist tsunami forces.
What are non-structural mitigation measures for cyclones?
Non-structural mitigation measures are:- a.) Hazard mapping:- a hazard map will illustrate the areas vulnerable to the cyclone in any given year. it is a effective mitigation tool. b.)Land use control designed so that least critical activities are placed in vulnerable areas.Location of settlements in the flood plains is of utmost risk.Vulnerable areas should be kept for parks,grazing or play grounds. c.)Cyclone fore casting and warning :- better forecasting for cyclones ,early and timely warning to the people who are likely to be affected leads to better preparedness and reduced impact to life,property, livelihood and livelihood and infrastructure.
What are the non structural mitigation for cyclones?
Non-structural mitigation for cyclones includes strategies that do not involve building physical structures but instead focus on preparedness and community resilience. This can involve improving early warning systems, conducting public education campaigns on cyclone safety, and implementing land-use planning to restrict development in high-risk areas. Additionally, developing emergency response plans and promoting community-based disaster risk management can enhance resilience against cyclonic events. These measures collectively aim to reduce vulnerability and enhance the capacity to respond to cyclones effectively.
What are the structural and non structural mitigation measures for landslides?
Structural and non-structural mitigation of landsliderisk in road connections: the integration of monitoringand early warning devices in the Scascoli Gorges(northern Apennines, Italy)The Scascoli Gorges (25 km south of Bologna, Savena River Valley) display an intrinsicstructural predisposition to slope instability, due to stratigraphic and tectonicfeatures, resulting in several landslide bodies of different types and sizes. In particular,both the left and the right cliffs of the Gorges have been affected by huge rock fallsinvolving weathered and fractured sandstones. The rock fall events recorded in the lastfew years are impressive: on October 15th, 2002 a rock volume of about 20.000 cubicmeters detached from the left cliff, damming the Savena riverbed and completelydestroying 150 meters of the Fondovalle Savena provincial road. On March 12, 2005a rock slope failure of 30.000 cubic meters occurred, developing as a toppling-rockfall that, again, dammed the river and destroyed the road for a length of about 100 m.Despite the fact that the road represent an important connection from the upper part ofthe valley to the city, in both cases, no accidents and casualties were recorded.From 2005 onwards a large civil protection plan was set up in order to design protectionand consolidation works, and to manage the risk posed to the road on the elementsat risk, both directly and indirectly (people, road, economic activities etc.). Site characterization,in situ monitoring, slope stability analyses and alarm system, in the frameof residual risk assessment and management after the 2005 event, are here discussed.After the last major rockfall event and the first emergency response (removal of fallenblocks), two main sources of risk threatened the road in the Scascoli Gorges. One wasthe risk that single rock blocks resting on unfavourably orientated joints (volume inthe order of dm3 to 100m3) would detach from the cliff and impact the road. The otherwas the risk associated with an overall failure of the rock cliff such occurred in 2002and 2005 (volume in the order of 105m3). In order to reduce the hazard and to drop therisk below an acceptable level, both structural and non-structural mitigation measureswere combined.The first mitigation measure consisted of slope flattening and benching aimed to reducethe driving force in the cliff affected by the 2005 rockfall. Slope was excavatedby blasting and heavy ripping to an average slope of approximately 50°. Slope profilinghad the double positive effect of increasing the global safety factor of the rockslope and grading the slope away from the road, thus reducing the hazard related tosingle rockfalls. Furthermore, a rockfall barrier with an energy absorption capacity of1000 kJ was installed at mid-slope where the cliff was still too close to the road (10-15m). Structural measures also included the construction of a earth wall at the toe of thecliff, the protection of river banks against undermining, and the rebuilding of the roadsubgrade using large rock blocks fastened with concrete and stainless steel nets.Non-structural mitigation measures consisted of an automated monitoring system andof a cable alarm system. The monitoring system is composed by three electrical crackmetersinstalled across major discontinuity planes and one thermometer. The data arecollected every four hours, stored in the field and retrieved weekly via GSM. The alarmsystem was installed along the road guard rail and it consists of a cables pair coupledwith a current detector. Whether an interruption of the current flow is detected, thesystem turn on two red traffic signal signs placed at the entrance of the Gorges andsend an SMS alarm to nominated mobile phone numbers.The efficiency of the mitigation measures were evaluated in terms of risk reduction.The level of risk from rockfall was quantified by considering the following hazards:i) impact of a rock on a moving vehicle, ii) impact of a rock on a stationary vehicle;iii) impact of a vehicle on a stationary rock that is obstructing or blocking the road.The overall risk level was computed as sum of the probabilities of single accidentsmultiplied by the probability of death. By comparing the overall risk before and afterthe works, we demonstrated that the adopted mitigation measures have successfullydecreased the level of risk and that the level of residual risk is well below the valuescommonly selected for acceptable risk.
What are non metric measures?
Feet, pounds, gallons.
What are the structural and non structural mitigation for earthquake?
Structural mitigation measures for earthquakes include building reinforcements such as base isolators and bracing, while non-structural measures include securing heavy furniture, installing automatic gas shut-off valves, and creating emergency plans. Both types of mitigation aim to reduce damage and ensure safety during seismic events.
Structural and non structural mitigation of drought?
The structural and non structural mitigation of drought is the displacement of people. Death of livestock and plants is another structural and non-structural mitigation of drought.
What is non structural mitigation?
displacement of people
What are mitigation strategies for flood?
there are two types; structural and non structural
What are two general approaches to flood mitigation?
Two general approaches to flood mitigation are structural and non-structural measures. Structural measures include the construction of levees, dams, and floodwalls to physically block or redirect floodwaters. Non-structural measures involve planning and policy strategies, such as land use zoning, floodplain management, and improving early warning systems to reduce vulnerability and enhance community resilience. Both approaches aim to minimize the impact of flooding on people and property.

What do you understand by mitigation why is it important give three examples of non- structural mitigation?
mitigation efforts help the people by creating safer communites and reducing loss of life and property is called mitigation
What are the structural and non structural mitigation strategies of a tsunami?
Structural Mitigation:- • Increase the river dike heights • Evacuation routes identification • Retrofitting of vulnerable structures for tsunami resistance • Engineered structures • Tsunami water breaks • Sea walls & coral reefs Non structural Mitigation:- • Public Awareness • Hazard mapping & vulnerability analysis • Risk identification, zoning & mapping • Training of all concerned • Land Use Management • Tsunami warning system

What are the mitigation strategies for floods?
Mitigation strategies for floods include the construction of flood control structures such as levees and dams, implementing land-use planning to avoid building in flood-prone areas, improving stormwater management systems, and promoting early warning systems and emergency preparedness. Additionally, restoring natural floodplains and wetlands can help absorb excess water and reduce flood risk.
