Consideración de los huracanes en el diseño de las estructuras en la República Dominicana

La gestión de riesgo, es un mecanismo de protección, que mediante la identificación anticipada de las acciones generadas por un evento catastrófico, ayuda a reducir de la vulnerabilidad y a identificar las medidas a tomarse para evitar o mitigar los impactos de estos eventos o desastres. A sabiendas de que la seguridad absoluta no existe, surge la necesidad de que las construcciones de hoy día deben ser adaptadas en función de las características de su entorno y los peligros que se presentan en el mismo. La sociedad moderna identifica su exposición al riesgo y exige que estos sean tratados de manera adecuada garantizando que la obra no suponga ningún tipo de amenaza. Este Trabajo de Fin de Máster está guiado a la identificación de aquellas acciones e influencias que representan un peligro para las estructuras de la República Dominicana por el paso de los huracanes. Con esta información será posible la creación de un catálogo de Riesgos y Soluciones, cuya finalidad sea reducir la exposición y vulnerabilidad de las construcciones frente a un evento catastrófico como lo es paso de un huracán. Para realizar la investigación se ha utilizado el “Método LOGRO”, el cual trabaja bajo tres distintos métodos de investigación, los cuales son la: La revisión de documentación, una sesión de tormenta de ideas y encuestas a expertos (Método Delphi). Ya realizada la investigación e identificados los riesgos, se han realizado una serie de catálogos de Riesgos y Soluciones, que faciliten la creación de un plan de gestión de riesgos, para garantizar un diseño estructural resiliente, en las zonas expuestas al paso de los huracanes en la República Dominicana. Risk management is a protective mechanism, which by the early identification of actions generated by a catastrophic event, helps reduce vulnerability and to identify the measures taken to prevent or mitigate the impacts of these events or disasters. Knowing that there is no absolute security, there is the need for the construction of today must be adapted according to the characteristics of their environment and the dangers presented herein. Modern society identifies their exposure to risk and requires that these are adequately addressed by ensuring that the work does not pose any threat. This Final Project Master is guided to the identification of those actions and influences that pose a threat to the structures of the Dominican Republic by the hurricanes. With this information it is possible to create a catalog of risks, and solutions aimed at reducing the exposure and vulnerability of the buildings facing a catastrophic event as it is a hurricane. To make research has used the "LOGRO method", which works low three different research methods, which include: The review of documentation, a session of brainstorming and expert surveys (Delphi method). And conducted research and identified the risks, there have been a number of catalogs and Risk Solutions that facilitate the creation of a risk management plan to ensure a structural design resilient in areas prone to hurricanes in the Dominican Republic

Riesgos de taludes y terraplenes en obras lineales de la República Dominicana

Partiendo de la idea de la concurrencia de un fenómeno y de las acciones que se deben llevar a cabo, se debe entender la Gestión de Riesgos como una determinación de relaciones entre lo que se asume como vulnerable, y la forma en la cual se estimará la probabilidad de un determinado hecho. A medida en que pasa el tiempo, se torna más importante el tema de vulnerabilidad y de riesgo a nivel mundial. La vulnerabilidad se vuelve más notoria ante la presencia de determinados peligros naturales como lo son los siguientes: deslizamientos de tierras, movimientos sísmicos, desbordes de ríos e inundaciones. (Pérez Soriano, 2014) La vulnerabilidad se ve en su mayoría más afectada por acciones antrópicas como lo son la construcción de viviendas en lugares de alto riesgo, como por ejemplo, viviendas en los taludes de obras lineales. Estas viviendas están condicionadas por la localización, el uso del suelo, la infraestructura, la distribución y la densidad de la población, su capacidad de organización, etc. La Gestión de Riesgos se vuelve cada vez más exigente en cuanto a la calidad de los servicios ofertados, además de también, cumplir con la responsabilidad jurídica que implica la concepción, diseño y construcción de taludes y terraplenes en obras lineales. (Pérez Soriano, 2014) El presente trabajo de investigación se centra en la identificación y valoración de los riesgos de taludes y terraplenes en obras lineales de la República Dominicana. De esta manera se busca disminuir el riesgo de la rotura o fallo de un talud o terraplén, y el número de víctimas que puedan ser afectadas por el mismo, concluyendo con un catálogo de riesgos para taludes y terraplenes en obras lineales. Based on the idea of the occurrence of a phenomenon and the actions to be carried out, Risk Management should be understood as a determination of relationships between what is assumed to be vulnerable, and the way in which the probability of a particular event will be estimated. The issue of vulnerability and risk becomes more important worldwide as time goes on. Vulnerability becomes more evident in the presence of certain natural hazards such as: landslides, earthquakes, overflowing rivers and flooding. (Pérez Soriano, 2014) It has become evident that vulnerability is mostly affected by human actions, such as the construction of housing in high-risk locations, for example, man-made slopes. These properties are conditioned by the location, land use, infrastructure, distribution and density of the population, organizational skills, etc. Risk management is becoming more discerning about the quality of the services offered, in addition to the compliance of the legal responsibility that the conception, design and construction of slopes and embankments in linear works require. (Pérez Soriano, 2014) This research project focuses on the identification and valuation of the risks derived from slopes and embankments in linear works of the Dominican Republic, in order to reduce the risks of failure of a slope or embankment and the number of victims who may be affected from it. Concluding with a risk catalogue for slopes and embankments in linear works.

Modelización de las fallas activas para la estimación de la Peligrosidad Sísmica. Aplicación Metodológica en Haití

The development of this Master's Thesis is aimed at modeling active for estimating seismic hazard in Haití failures. It has been used zoned probabilistic method, both classical and hybrid, considering the incorporation of active faults as independent units in the calculation of seismic hazard. In this case, the rate of seismic moment is divided between the failures and the area seismogenetic same region. Failures included in this study are the Septentrional, Matheux and Enriquillo fault. We compared the results obtained by both methods to determine the importance of considering the faults in the calculation. In the first instance, updating the seismic catalog, homogenization, completeness analysis and purification was necessary to obtain a catalog ready to proceed to the estimation of the hazard. With the seismogenic zoning defined in previous studies and the updated seismic catalog, they are obtained relations Gutenberg-Richter recurrence of seismicity, superficial and deep in each area. Selected attenuation models were those used in (Benito et al., 2011), as the tectonic area of study is very similar to that of Central America. Its implementation has been through the development of a logical in which each branch is multiplied by an index based on the relevance of each combination of models. Results are presented as seismic hazard maps for return periods of 475, 975 and 2475 years, and spectral acceleration (SA) in structural periods: 0.1 - 0.2 - 0.5 - 1.0 and 2.0 seconds, and the difference accelerations between maps obtained by the classical method and the hybrid method. Maps realize the importance of including faults as separate items in the calculation of the hazard. The morphology of the zoned maps presented higher values in the area where the superficial and deep zone overlap. In the results it can determine that the minimum values in the zoned approach they outweigh the hybrid method, especially in areas where there are no faults. Higher values correspond to those obtained in fault zones by the hybrid method understanding that the contribution of the faults in this method is very important with high values. The maximum value of PGA obtained is close to Septentrional in 963gal, near to 460 gal in Matheux, and the Enriquillo fault line value reaches 760gal PGA in the Eastern segment and Western 730gal in the segment. This compares with that obtained in the zoned approach in this area where the value of PGA obtained was 240gal. These values are compared with those obtained by Frankel et al., (2011) with those have much similarity in values and morphology, in contrast to those presented by Benito et al., (2012) and the Standard Seismic Dominican Republic

Ciudades intermedias latinoamericanas ante modelos urbanos externos

En su proceso de crecimiento, las ciudades de América Latina y el Caribe (ALC) han tenido una vinculación histórica con la dinámica de implementación de herramientas, metodologías y proyectos urbanos, gestados en otros contextos, especialmente desde Europa (UE) y Estados Unidos (EE.UU). Desde la época colonial hasta hoy, la mayor parte de las ciudades de ALC han experimentado diversos tipos de influencia urbana externa, que han dejado huellas tangibles. Esta influencia ha ido variando a través de los años, desde la implantación directa de un modelo urbano, propia de la época colonial; hasta la importación de modelos urbanos total o parcialmente, de manera autónoma y ajena al origen de este. Actualmente, en ALC se han generado diversas iniciativas para abordar las necesidades urbanas desde sus especificidades, pero los instrumentos y proyectos vanguardistas utilizados en países desarrollados, siguen teniendo mayor fuerza de atracción y diseminación que las iniciativas vecinas. Se observa que las ciudades intermedias, que crecen con mayor velocidad que las grandes ciudades, también participan activamente en este proceso, aunque con otras limitaciones y condicionantes, diferentes a las encontradas en las grandes ciudades de la Región. ¿Por qué se produce esta dinámica?, ¿quiénes participan?, ¿cuáles son sus procesos?, ¿responden a las necesidades del complejo y diverso contexto urbano latinoamericano? Las Ciudades Intermedias Latinoamericanas ante los Modelos Urbanos Externos, es una investigación que aborda la dinámica de implementación de modelos de desarrollo urbanos1 exógenos, en ciudades emergentes que, en su proceso de crecimiento, tienden a repetir patrones de las grandes ciudades, y que en sí mismas, representan una oportunidad ante los desequilibrios territoriales de ALC. Esta dinámica, ha sido abordada por investigadores de diversas disciplinas, cuyos puntos de vista en muchas ocasiones no coinciden, pero revelan que estamos frente a una discusión de larga data, entre las visiones modernistas y las visiones identitarias de la historia urbana de ALC. Por ello, el trabajo recoge la evolución de los procesos de toma de decisiones, desarrollados bajo un efecto cascada (Global, Internacional, Regional, Nacional, Subnacional, Local), donde actualmente el nivel Local asciende a espacios del nivel Regional (ALC) e Internacional; pasando de meros receptores de políticas generadas en un plano superior derivadas de las relaciones geopolíticas y geoeconómicas de escala mundial; a ser sujetos proactivos del desarrollo de sus territorios. Para observar la concatenación de este proceso macro-disciplinar-micro (grosso modo), se plantea una herramienta metodológica de triangulación, desde la que se pueda visualizar el contexto en el que se produce la dinámica y como éste la condiciona. Con dicha metodología se abordará ALC como caso de estudio general, haciendo una aproximación al detalle en dos casos particulares: Ciudad Guayana (República Bolivariana de Venezuela) y Santiago de los Caballeros (República Dominicana). Estos casos, sumados a las observaciones de actores vinculados a la dinámica de transferencia de modelos urbanos, coadyuvarán en este esfuerzo de aproximación, para definir con más claridad un proceso que se incrementa y complejiza, en medio de la denominada “era de las ciudades”. ABSTRACT In its growth process, the cities of Latin America and the Caribbean (LAC) have had a historical link with the dynamics of implementation tools and engendered in other contexts, especially from Europe (EU) and the US methodologies (USA). From colonial times until today, most LAC cities have experienced various types of external urban influence that have left tangible traces. This influence has varied over the years, since the introduction of direct, typical of the colonial era; to import all or part independently and outside the origin of this urban model. Currently, in LAC they have generated various initiatives to address urban needs from its specificities, but notes that the instruments used in cutting-edge projects and developed countries, are still more attractive force and spread to neighboring initiatives. It is observed that the intermediate cities, which grow faster than big cities are also actively involved in this process, although with different constraints and other limitations to the big cities of the region. Why this dynamic occurs?, Who ?, which involved processes are ?, respond to the needs of complex and diverse Latin American urban context? Intermediate Latin American cities to external urban models, is a research that addresses the dynamics of exogenous implementation of urban development models in emerging cities in their growth process, they tend to repeat patterns of large cities, and represent a shot at LAC regional imbalances. This dynamic has been addressed by researchers from various disciplines, whose views often do not match, but show that we are facing a long-standing debate between modernists and identity visions on urban history of ALC. Therefore, the work shows the evolution of the processes of decision making, developed under a (global, international, regional, national, subnational, local) cascade effect, which currently stands at the Local level Regional level spaces (ALC) and International, from mere recipients of policies generated on a higher plane derived from the geopolitical and geo-economic relations worldwide; to be proactive in the development of their territories subject. To observe this process concatenation macro-micro-discipline (roughly), a triangulation methodology tool, from which it can view the context in which the dynamic occurs and how it affects what arises. ALC will address her as if general study, making an approach to detail two particular cases: Ciudad Guayana (Bolivarian Republic of Venezuela) and Santiago de los Caballeros (Dominican Republic). These cases, together with the comments of stakeholders involved in the dynamics of transfer of urban models, will assist in this effort approach to define more clearly a process that increases and more complex, amid the so-called "era of the cities".

Turismo y desarrollo sostenible en la provincia de Samaná, República Dominicana

El turismo en la República Dominicana se ha convertido en el motor económico del país, aventajando a actividades tradicionales como la agricultura y la manufactura. Esta transformación de la matriz productiva está sustentada, en gran medida, en la construcción de grandes hoteles en diferentes zonas litorales del país. El presente estudio se centra en la península de Samaná, área de reciente desarrollo turístico que es usada reiteradamente por el Estado dominicano como exponente del desarrollo sostenible, alcanzado a través del fomento del sector servicios. El objetivo principal es determinar la veracidad de esta afirmación, mediante la identificación y la caracterización de los principales impactos ambientales, sociales y económicos generados por la construcción de complejos hoteleros. Además, se analizará el cumplimiento de la legislación ambiental por parte de las empresas constructoras de grandes hoteles así como el rol del organismo estatal competente en la conservación del entorno natural.
