This study assesses precipitation deficits in the São Francisco River Basin using two decades of satellite-derived data, revealing longer and drier periods in 2008-2018, with the strongest deficit observed in summer and particularly impacting the upper part of the basin.
This study evaluates drought impacts in the São Francisco River Basin from 1961 to 2019, utilizing the Standardized Precipitation Index (SPI) based on INMET pluviometric data, revealing contrasting short-term drought occurrences between Upper and Lower São Francisco, with prolonged droughts observed in the Sub-Medium and Middle São Francisco regions, supported by Cluster Analysis demonstrating similarities in drought variables across different basin regions.
In this work, we assessed the importance of a conceptual representation of hydrological processes when modelling atmospheric circulation.
In this study, we used a land surface model integrated with a river routing scheme to analyze the hydrological alterations expected in the Tapajós River basin, a large portion of the Brazilian Amazon, caused by two environmental drivers: climate and land use.
This paper presents a study carried out in the Tapajós River (Brazil), a 477,000 km2 basin in South-eastern Amazonia, in which we analysed the role of annual land cover change on daily river flows.
In this technical note, we describe the integration of the Ecosystem Demography (ED2) model with a hydrological routing scheme.
This work describes the two-way coupling performed between the regional atmospheric model Brazilian Regional Atmospheric Modeling System (BRAMS) and the hydrological model MGB-IPH.
In this work, a first-order upwind and a high-order flux-limiter schemes for solving the advection-diffusion equation on unstructured grids were evaluated.
In this study, we focused on identifying the most important patterns of monthly time series after biomanipulation. Moreover, we tried to quantify how those variables are interconnected with each other.
In this study, this sugarcane expansion was mapped for the River Grande basin in the northern São Paulo, considering the real extension of the plantation area in 1993, 2000, 2007 using Landsat satellite images.
This study aimed to evaluate the effects of sugarcane expansion on surface runoff and evapotranspiration in the Rio Grande basin, Brazil, as concerns have raised on the effects of the replacement of native vegetation and traditional crops to sugarcane plantations may have on local hydrology and climate.
This study explores the short-, medium- and long-term impacts of expansion of the sugarcane plantation on the water balance of the Rio Grande Basin, Brazil, as estimated by changes in evapotranspiration, soil moisture content and surface runoff calculated by a hydrological model.
This paper presents an application of the model to the Guaíba River, including the region of the Jacuí River delta with its intricate network of channels and islands. Two methods for solving the transport equation were tested: one based on a central difference numerical scheme and another based on a high-resolution scheme.
