This work aims to answer whether climate change is a precursor to updating the rain equations developed in different regions of Brazil. The methodology was based on a Systematic Review of the existing literature, made through the "Periódicos Capes" portal. The results showed that in some cities, there are no rain equations and not enough rain measurements available, so, in these cases it is not possible to study Climate Change and the formulations of Rain Designs. However, in places where data are available, the need to update the Rain Design equations are evaluated using recent historical rainfall data, and it was found that these changes could be explained by climate change.

O custo das geotecnologias estão se tornando mais acessível. A capacidade de gerar mapas em tempo real, com acesso ubíquo e aplicativos baseados em plataformas geocolaborativas desenvolvidas para os mais diferentes propósitos estão se multiplicando, permitindo aos usuários gerar, compartilhar, e coletar informações sobre o espaço geográfico. Mesmo assim, as geotecnologias empregando o Sistema de Informações Geográficas (SIG) ainda são limitadas entre as polícias militares ambientais brasileiras. Essa falta de difusão das geotecnologias ocorre devido a ausência de treinamento específico, requerendo um constante aperfeiçoamento desses profissionais. O estágio atual da evolução da geotecnologia por meio da computação em nuvem, design centrado no usuário, e geocolaboração exigem que estruturas de comando e controle repensem suas estratégias. Várias plataformas estão disponíveis e abertas para desenvolvedores criarem aplicativos com essa tecnologia. Este artigo analisa a potencial aplicabilidade da geocolaboração nas atividades de fiscalização ambiental, por meio de um estudo de caso no CPAm/PMERJ. ; El costo de la geotecnología es cada vez más accesible.

La etapa actual de la evolución de la geotecnología a través de la computación en la nube, el diseño centrado en el usuario y la geo-colaboración requiere estructuras de comando y control para repensar sus estrategias. Hay varias plataformas disponibles y abiertas para que los desarrolladores creen aplicaciones con esta tecnología. Este documento analiza la aplicabilidad potencial de la geo-colaboración en actividades de vigilancia ambiental a través de un estudio de caso en CPAm/PMERJ. ; The cost of geotechnologies are becoming more accessible. The capacity to generate real-time maps with ubiquitous access and applications based on geocollaborative platforms developed for the most diverse purposes have been multiplying, allowing users to generate, share, and collect information about geographical spaces. Even so, the geotechnologies employing geographic information system (GIS) are still limited among the Brazilian environmental military police. This lack of geotechnologies diffusion occurs due to the absence of specific training, requiring a constant update from these professionals. The current stage of evolution on geotechnology through cloud computing, user-centered design, and geocollaboration demands the police command-and-control structures to rethink their strategies. Several platforms are available and open for developers to create applications under this technology. This article analyzes the potential applicability of geocollaboration in environmental inspection activities, through a case study in the CPAm/PMERJ.

This article presents a literature review about urban floods, with a specific analysis concerning the Macaé River basin in Rio de Janeiro, Brazil. The main topics of the study are: (i) legal framework of water resources management; (ii) overview of urban floods in Brazil, focusing on the city of Macaé; (iii) methods of control and mitigation of urban floods; (iv) hydrological and computational modeling applied to the study of floods; and finally, (v) characterization of the Macaé River basin, with an emphasis in the context of floods and inundations. The research confirms the relevance of flood studies for the region, both by the expressive record of flooding events and by the lack of recent investigations about this issue. According to the current trend practiced in flood management, proposals for the city should be based on integrated interventions that consider the peculiarities of the basin. Compensatory techniques and the renaturalization of rivers and streams are two prominent approaches to this context. The modeling of the basin and the simulation of these measures can provide data that will support the basin management plan and the work of other relevant public institutions.
