13. PROBABILITY DISTRIBUTION FUNCTIONS APPLIED IN THE WATER REQUIREMENT ESTIMATES IN IRRIGATION PROJECTS
RESUMO A Espanha possui um terço de toda área irrigada da Europa. A área irrigada no país responde por 15% da área cultivada e quase 60% da produção agrícola nacional. O conhecimento da variabilidade espacial e temporal da evapotranspiração de referência (ETo) e da teoria probabilística dos eventos extremos é um ponto essencial para elaboração

14. Application of SAC-SMA and IPH II hydrological models in the Teles Pires River basin, Brazil
RESUMO A parametrização e a análise do desempenho de um modelo hidrológico permitem sua consolidação para avaliação de estratégias de gerenciamento de recursos hídricos e para previsão de eventos extremos. Nesse contexto, o objetivo do trabalho foi avaliar o desempenho dos modelos chuva-vazão Soil Moisture Accounting (SAC-SMA) e IPH II para pred

15. Application of indices for water resource systems stress assessment
RESUMO O presente artigo teve como objetivo apresentar uma metodologia para avaliação do estresse hídrico de sistemas de recursos hídricos por meio de índices. Neste caso, aplicou-se a metodologia proposta ao Sistema Cantareira, um dos principais sistemas produtores de água da Região Metropolitana de São Paulo (RMSP). Foram utilizados para esta aval

16. Using climate change models to assess the probability of weather extremes events: a local scale study based on the generalized extreme value distribution
ABSTRACT Regional climate models (e.g. Eta) nested to global climate models (e.g. HadGEM2-ES and MIROC5) have been used to assess potential impacts of climate change at regional scales. This study used the generalized extreme value distribution (GEV) to evaluate the ability of two nested models (Eta-HadGEM2-ES and Eta-MIROC5) to assess the probability of dai

17. SPATIALIZATION OF THE ANNUAL MAXIMUM DAILY RAINFALL IN SOUTHEASTERN BRAZIL
ABSTRACT Extreme rainfall can lead to heavy damage and losses, such as landslides, floods and agricultural productivity as well as the loss of human and animal lives. To mitigate these losses, water resources management policies are needed, among other goals, to study and predict the frequency of such events in a given region to minimize their harmful effect

18. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

19. Thermal profiles in pervious concrete during summer rain simulations
ABSTRACT Pervious concrete pavement systems may have many environmental benefits including the mitigation of heat island impacts. This mitigation is a complex combination of pervious concrete’s insulating capability and its ability to store water which may provide evaporative cooling. However, the introduction of water may also bring heat into the system,

20. Comparative study of tall building response to synoptic and non-synoptic wind action
Abstract Until the beginning of the 21st Century, the characteristics of wind for purposes of structural analysis and design, as reflected in wind codes worldwide, were based on the behavior of wind currents in the vicinity of the ground surface observed in so-called synoptic events. It was only recently recognized that the latter are not the only cause of w

21. Phenology of Promestosoma boggianii (Diplopoda: Polydesmida: Paradoxosomatidae) in a Neotropical floodplain
ABSTRACT Studies that address biodiversity and its supporting mechanisms in different ecosystems are fundamental to understanding the relationships between species and the prevailing environmental conditions within each habitat type. This study presents information on the phenology of Promestosoma boggianii (Silvestri, 1898) and its association with seasonal

22. Variabilidad de Baja Frecuencia de la Persistencia de la Temperatura en el Sudeste de Sudamérica
Abstract Eight reference stations in south-eastern South America are analysed to derive the auto-covariance and auto-correlations of maximum and minimum temperature. Through the analysis are observed oscillations of periods between 18 and 25 years in the series studied. These periodicities show changes over time, especially in the 1950-1970 period. The excep

23. Experiencias en la aplicación de la educación ambiental como herramienta para la adaptación al cambio climático en espacios comunitarios, en Holguín-Cuba
Climate change affects the living conditions of the population, generating negative impacts on community areas. The rising temperatures, increased intensity and frequency of extreme weather events and other effects, damage the economy, politics, environment and society. These effects can be controlled by an effective adaptation, is environmental education as

24. Short-term stability of estuarine benthic assemblages: are storms pattern-defining events?
Storms, associated with strong winds and heavy rains, are often the most severe physical disturbances in shallow coastal areas causing instability to sedimentary environments. We hypothesized herein that if storms influence short-term assemblage structure of macrofauna, then assemblages should change after storms, while remaining relatively stable over calm
