1. Numerical Simulation of Debris Flows of the Catastrophic Event of February 2019 in Mirave - Peru
Resumo Os fluxos de detritos são fenômenos geofísicos provocados por chuvas torrenciais, que ocorrem em áreas montanhosas, e se caracterizam pelo desprendimento de materiais de declives e de leitos de rios e seu consequente arraste água abaixo através de bacias e córregos. Os fluxos de detritos carregam consigo, em geral, lodo, água e rochas, e podem

2. Puls method for events simulation in a lot scale bioretention device
RESUMO Biorretenção é uma técnica aplicada para tratar e reduzir o escoamento superficial gerado em áreas urbanas. Embora essas instalações apresentem processos complexos, um modelo simples com poucos parâmetros pode ser útil para seu projeto. Este artigo relata uma aplicação do método Puls como uma ferramenta quantitativa de simulação de biorr

3. Aproveitamento de água de chuva no meio urbano e seu efeito na drenagem pluvial
There is an increasing interest from the society in rainwater harvesting and use in urban areas, due to the benefits that this practice provides, such as: economic, environmental and urban flooding control. This interest may be perceived by the emergence of government regulations and increased availability of specific products in the domestic market for the

4. Transporte de glifosato pelo escoamento superficial e por lixiviação em um solo agrícola
Glyphosate was determined in runoff and leaching waters in agricultural soil that received an application of active ingredient and was exposed to simulated intensive rain conditions. The concentrations decreased during the simulation period and the concentrations of the runoff were higher than those achieved in the samples of leaching waters. The concentrati

5. Simulação experimental da interação vento-chuva / Experimental simulation of the wind-rain interaction
Simultaneous occurrences of the combined action of rain and wind in different types of structures have been observed around of the world in the last 20 years. This mechanism has been causing curiosity to engineers and researchers due to their jeopardizing consequences to constructions. In these last twenty years people has been seeking for a way to simulate,

6. Modelagem da dinâmica de crescimento de uma Floresta Ombrófila aerta do estado de Rondônia / Modelling of growth dynamics of tropical rain forest of State of Rondonia, Brazil.
A model of the growth dynamics of forests was developed applying Bertalanffy growth model (BGM) y=a[(1ebt)c] for individual trees. Based on linearized relationship with diameter and height equation LnH=b0+LnD and volume equation V=b0Db1Hb2 mutually compatible equations for diameter, basal area, height and volume were generated, adjusting parameters a and c o

7. Numerical simulation of the rainfall diurnal cycle over the amazon basin during the rainy season / Simulação numérica do ciclo diário da precipitação sobre a bacia amazônica durante a estação chuvosa
The diurnal cycle is the climatic mode directly modulated by surface forcing. Numerical models fail to simulate it, especially over the continental areas during the warm season. Previous studies show that in the Amazon Basin the maximum rainfall is simulated around four hours before to the one observed with rain gauges. Thus, this work emphasizes the importa

8. Precipitation forecast aided by weather radar for early warning system of urban floods / Previsão de chuva com auxílio de radar de tempo visando a um sistema de alerta antecipado de cheias em áreas urbanas
To reduce human and material losses during floods it is feasible to concisely study the rainfall forecast as the main part of an early warning system. The use of weather radar information, when linked to physically-based forecast models, can contribute for monitoring and forecasting of intense rainfall episodes. Thus, the rainfall forecast, based on using of

9. Remoção de resíduos de fungicidas por meio de chuva simulada e de irrigação em batateira e tomateiro / Removal of fungicides residue by simulated rain and irrigation in potato and tomato
The aim of this study was to evaluate the removal of mancozeb (Mn), mancozeb NT (NT), and copper hydroxide (Hc) residues from potato and tomato leaflets by rain and/or irrigation. Under controlled conditions different intensities of simulated rain (0, 30, 40, 60, and 97 mm / h), duration (5, 10, 20, and 40 min) and time of drying of the sprayed fungicide sus

10. Contribution of different energy systems for rowing on the water and on different rowing ergometers / Contribuição dos sistemas energéticos na água e em diferentes ergômetros de remo
Rowing is a sport that can be subject to environmental conditions as it is practiced outdoors. Wind, rain and cold climates can disturb or even impede the execution of rowing on the water. For that reason, indoor rowing is considered to be an important means of training. The most used form of indoor training and evaluation of athletes is the rowing ergometer

11. IMPLEMENTATION AND EVALUATION OF METODOLOGIAS TO FORECAST FOR ÃNDICES REGIONAL RAIN INDEX IN THE RAINY SEASON IN REGION SEMI-ÃRIDA OF NORDESTE OF BRAZIL / AplicaÃÃo e AvaliaÃÃo de Metodologias para PrevisÃo de Ãndices Regionais de Chuva no PerÃodo da Quadra na RegiÃo Semi-Ãrida do Nordeste.
This study presents the application and evaluation of two distinct forecast systems Seasonal Regional Rainfall Indices on the Semi-Arid Northeast of Brazil and Basins of the Cearà State Regions. In the first case a set of numerical simulations (1971-2000) obtained from system forecast based on the theory of dynamic downscaling is used as data to input in th

12. Modelagem de lixiviação do herbicida picloram atraves de lisimetro de drenagem sob vegetação de Brachiaria decumbens / Modeling of picloram herbicide leaching in a lysimeter under Brachiaria decumbens vegetation
Picloram is one of the most used herbicides in the control of weeds in pastures areas, especially the ones of difficult eradication. Many are the stories of wells and springs contamination with herbicides residues as a result of its leaching in grounds. Due to the lack of knowledge and available data on the destination of the picloram in brazilian grounds, r
