The indicators may be combined into a single vulnerability index for a region or sector, and may be compared from one region or sector to another.

In Acapulco, vulnerability and hazard increased in recent years, and hence the frequency of flood events Fig. Journal of Geophysical Research: Natural Hazards56 1 Spatially distributed storm runoff depth estimation using Landsat images and GIS. The challenge is to determine the proper combination of vulnerability and hazard that yields the most adequate spatial and temporal representation of the disaster.

When this information is combined with a vulnerability estimate, those regions with a large probability of experiencing a flood are identified Fig. Structural vulnerability aflas measures would result in benefits for several region and communities, not only by reducing the number of natural disasters, but also by achieving sustainable development goals.

Natural Resources Conservation Service. Natural disasters should be examined within a risk-perspective framework where both natural hazards and vulnerability are considered. In general, they result from an intense hydrological cycle and increased human activities that involve changes in the environment. The trend in the number of days with precipitation above P95 shows that more frequent riesyos rainstorms are occurring riesgls a large area of the Mexican territory Aguilar et al.

April 17, ; Accepted: Cuenca model del Sistema serrano de La Venta Argentina.

Atmospheric data analysis No. An operational objective analysis system. There are other factors that increase the risk of flooding, which have not been examined here but that require special consideration. The vulnerability index to heavy rainfall was defined for catchment areas Fig. Computers and Electronics in Agriculture37 1 Inundaciones en el Estado de Veracruz.

United Nations Disasters Relief Coordinator. This requires finding creative ways to represent this effect when insufficient data is a limitation.

A risk-management approach should be followed —including landscape planning— for regions that are highly vulnerable to intense rainfall. DesInventar does not provide an actual account of the physical characteristics of floods, but serves as a flood-activity denapred.

Floods related to intense rains are becoming more frequent due to climate change e.

Flood processes and hazards. The midsummer drought over Mexico and Central America. INEGI, and In this way, it is through the spatial and temporal comparison of risk and flood frequency that the adequacy of vulnerability can be evaluated, since there are no historical records of the magnitude of floods for a cenzpred quantitative assessment.

Therefore, more floods are largely the result of human activities, given the important land-cover transformations.

Protección Civil :: Baja California Sur

On the other hand, the vulnerability to heavy rainfall depends on the physical conditions of the basins. The present study describes a methodology to quantify vulnerability and construct a risk model that spatially and temporally explains floods in recent decades.

Consequently, in this region the higher incidence of floods is primarily due to the increase in hazard activity. An increase in the number of floods in recent decades is more evident in the states close to the Gulf of Cenxpred, in the central Highlands including the Mexico City Metropolitan Areathe southern coast of the Aflas Pacific and parts of northern Mexico Fig. Disasters, development and environment In particular, the present analysis focuses on how the degradation of basins due to deforestation increases the risk of flooding when heavy rainfall occur.

Modelo Digital de Elevaciones – Continuo cenarped elevaciones mexicana 3. However, vulnerability to rainfall should also include factors such as the edaphic characteristics of soil, antecedent soil moisture condition AMCterrain slope, and watershed compactness, since these also cenaprec flood intensity. The number of floods Last forty years is higher in regions where physical vulnerability, related to the local orography and the presence of rivers, results in riesfos runoff.

AtmospheresD Increased watershed vulnerability due to land-cover changes is the primary factor leading to more floods, particularly over south-central Mexico.

Baja California Sur

The capability of the flood-risk model for Mexico was tested by comparing the observed and modeled frequency of floods for the period. The slope of the terrain influences the amount of runoff and flood-prone areas.

Atlaa 2 describes the data and methodology used in the study.
