ABSTRACT Maintaining water availability and electric energy production are the major concerns for future in countries which extremely dependent on their resources like Brazil. The objective of this study was to assess impacts climate change streamflow therefore hydropower potential Grande river basin headwater region, Southeast For purpose, SWAT model used simulate hydrological behaviour headwaters under Representative Concentration Pathways 4.5 8.5 scenarios, obtained from Regional Climate...
Abstract Brazilian Cerrado biome is the largest and richest tropical savanna in world. In order to understand effects of climate changes on hydrology basins, this paper investigates hydrological impacts change throughout 21st century under different emissions scenarios streamflow droughts Sono, Manuel Alves da Natividade Palma located Cerrado. For purpose, SWAT model driven by downscaling HadGEM2‐ES MIROC5 global models associated with RCP4.5 RCP8.5 were used three time slices (2011–2040,...
This study investigates the applicability of Satellite Precipitation Products (SPPs) in streamflow simulations performed Brazilian Cerrado biome, which is one world’s biodiversity hotspots. Local data from ground observations were used as a reference for evaluating Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Analysis (TMPA) and Integrated Multi-Satellite Retrievals Global Measurement (IMERG). The Soil Water Assessment Tool (SWAT) was to simulate subbasin Tocantins river basin....
Abstract Understanding the spatiotemporal behaviour of soil moisture in tropical forests is fundamental because it mediates processes such as infiltration, groundwater recharge, runoff and evapotranspiration. This study aims to model dynamics an Atlantic forest remnant (AFR) through four machine learning algorithms, these represent important knowledge gap under conditions. Random (RF), support vector machine, average neural network weighted k‐nearest neighbour were studied. The abilities...
Soil erosion is one of the most significant environmental degradation processes. Mapping and assessment soil vulnerability an important tool for planning management natural resources. The objective present study was to apply Revised Universal Loss Equation (RUSLE) using GIS tools Verde River Basin (VRB), southern Minas Gerais, in order assess vulnerability. A annual rainfall erosivity map derived from geographical model adjusted Southeastern Brazil, calculating value each pixel. maps...
Land-use changes are considered one of the most important factors that affect water resources. The objective this study was to investigate potential impacts land-use on hydrological behavior Upper Grande River Basin, southern Minas Gerais state, Brazil, based different scenarios using SWAT model. For purpose, daily streamflow records from Macaia gauge station were calibrated and validated under current land-use. To assess change four developed following official environmental planning...
Indigenous people have historically suffered devastating impacts from epidemics and continue to lower access healthcare be especially vulnerable respiratory infections. We estimated the coverage effectiveness of Covid-19 vaccines against laboratory-confirmed cases among indigenous in Brazil.We linked nationwide vaccination data with flu-like surveillance records studied a cohort vaccinated aged ≥ 5 years between 18th January 2021 1st March 2022. considered individuals unexposed date they...
ABSTRACT Soil erosion is currently one of the main concerns in agriculture, water resources, soil management and natural hazards studies, mainly due to its economic, environmental human impacts. This concern accentuated developing countries where hydrological monitoring proper surveys are scarce. Therefore, use indirect estimates loss by means empirical equations stands out. In this context, present study proposed assessment Revised Universal Loss Equation (RUSLE) with aid Geographical...
ABSTRACT Soil erosion is one of the most striking environmental degradation processes, which its mapping and assessment an important tool for management activities natural resource in river basins, allowing managers to implement policies sustainable land use occupation. This work aimed apply Revised Universal Loss Equation (RUSLE) a GIS environment upper Iguaçu basin, located at Paraná State, order assess vulnerability water as well concentration dissolved solids suspension estimate solid...
Successful streamflow forecasts depend on an adequate performance evaluation of the hydrological model. In this study, responses were compared using two models, physic-based and semi-distributed, Soil Water Assessment Tool (SWAT) Variable Infiltration Capacity (VIC), input data from Verde River Watershed, located in Minas Gerais state southern Brazil. This is a study one most important headwater watershed regions Brazil (Mantiqueira Range). Both models suitable for simulation, with values R2...
Hydraulic projects and water management require reliable hydrological data. The Araguaia-Tocantins River basin, in addition to agricultural use, has great potential for hydroelectric exploitation. However, the streamflow monitoring network Araguaia basin is composed of only a few stations, resulting lack regionalization reference streamflows technique that can help circumvent this data, enabling estimation from easily obtainable explanatory variables. In context, objective study was develop...
Abstract Understanding both carbon and nitrogen temporal spatial inputs by rainfall in tropical forests is critical for proper forest conservation management might ultimately elucidate how climate change affect nutrient dynamics ecosystems. This study aimed to quantify the net precipitation contribution Atlantic Forest’s total (C) (N), identifying potential differences between these regarding (seasonal monthly) scales. Rainfall samples were collected before after interacting with canopy from...
A subjetividade no uso do modelo SWAT, que diz respeito à escolha de critérios para discretização espacial da área estudo em sub-bacias e geração das unidades resposta hidrológica (URHs) foi a questão motivou elaboração deste artigo. Foram comparados os resultados obtidos (vazões mensais) com o hidrológico SWAT na simulação mensal uma bacia hidrográfica 2030 Km2 drenagem (rio Grande, MG), adotando diferentes URHs sub-bacias. Foi observado configuração um maior número adoção múltiplas...
A modelagem hidrológica em bacias hidrográficas consiste numa das principais e mais modernas ferramentas para gestão de recursos hídricos dimensionamentos hidrológicos, no entanto, vários são os questionamentos quando estudantes profissionais se deparam com aplicações práticas um modelo hidrológico. Neste contexto, a presente Revisão Literatura tem por objetivo apresentar, língua portuguesa, uma breve visão introdutória às definições aos conceitos básicos hidrológica, fim fomentar sua...
Abstract Background Forests are important for governing local and regional water nutrient dynamics. Thus, studying precipitation-forest interactions is essential to understand the consequences of land-use climate change hydrological cycles. This study aimed quantify contribution net precipitation on Atlantic Forest’s total carbon (C) nitrogen (N), identifying potential differences between these chemistry inputs regarding temporal (seasonal monthly) spatial scales.

A estimativa precisa da evapotranspiração é essencial para o desenvolvimento de estudos hidrológicos, principalmente em âmbitos bacias hidrográficas. Todavia, os dados necessários a aplicação do método Penman-Monteith padronizado pela FAO (PM) nem sempre estão disponíveis. Neste sentido, necessário que métodos mais simples como Priestley-Taylor (PT) e Hargreaves (HG) sejam avaliados superar esta barreira instrumental. Por conseguinte, presente trabalho teve objetivo avaliar desempenho dos PT...
