Similar to most countries, the Brazilian water resources management considers topographically delineated catchment as a territorial unit for policy implementation. Yet, previous studies have shown that catchments are not hydrologically isolated, and topographic limits often neglect the groundwater boundaries. Thus, studies on effective catchment ar...
Inherent errors in tipping bucket flow meters may limit monitoring data reliability. In this work, we perform the static and dynamic calibration of four large tipping buckets, apply different regression curves and investigate the possible measurement error sources. The volumetric capacity (static calibration) of each piece of equipment was determin...
General Circulation and Earth System Models are the most advanced tools for investigating climate responses to future scenarios of greenhouse gas emissions, playing the role of projecting the climate throughout the century. Nevertheless, climate projections are model-dependent and may show systematic biases, requiring a bias correction for any furt...
Automated soil moisture systems are commonly used in precision agriculture. Using low-cost sensors, the spatial extension can be maximized, but the accuracy might be reduced. In this paper, we address the trade-off between cost and accuracy comparing low-cost and commercial soil moisture sensors. The analysis is based on the capacitive sensor SKU:S...
Introduction: Runoff measurement and monitoring is a laborious, time-consuming, and costly task. Additionally, common runoff monitoring usually primarily provide water level, requiring information on the stage-discharge relation. Automatic equipment such as flow meter tipping bucket (TB) is a potential option to simplify and provide continuous runo...
The Brazilian Savanna (Cerrado) is the second‐largest South American biome that corresponds to almost two‐third of the national agricultural production. Extensive agricultural‐driven land‐use changes have significantly altered the landscape, causing increased soil erosion. Furthermore, projections of climate change effects on the Cerrado raise conc...
Changes in land cover and land use (LULC) are one of the main drivers of erosion and runoff. How ever, most research has relied on short-term observations and only focused on one or two land cover types. We investigated the long-term trade-off between common agricultural land covers (sugarcane, pasture, and soybean), runoff, and soil loss rates. We...
In recent decades, distributed temperature sensing (DTS) has emerged as a
robust technology for environmental applications, enabling high-resolution
temperature measurements along fibre optic cables (FOCs). The actively
heated fibre optic (AHFO) method is employed to monitor soil moisture (θ, m3
m-3), wherein the soil temperature subsequent to the...
The Natural Resources Conservation Service Curve Number method (NRCS-CN) is the most widely used approach to estimate runoff from rainfall events. However, the main uncertainties in the method remain in the use of an initial abstraction ratio (λ) standard value of 0.2 and discrepancies between computed and standard tabulated Curve Number (CN) value...
The assessment of flood vulnerability is a complex task that involves numerous uncertainties. Within this context, sensitivity analyses are crucial to better understand the variability of vulnerability index outcomes according to different input parameters. The present study sheds light on the importance of assessing the sensitivity of different cr...
The present work proposed serious games through a simplified water balance as a water resources management tool to assist in decision-making on problems such as the current strong migratory flows. In this pedagogical proposal, five Brazilian hydrographic basins were evaluated considering different scenarios of water demands, soil storage capacity,...
Brazil is seen as a potential world breadbasket in which an increase of around 40% in its current production is expected by the year 2050 to attend food demand imposed by world population growth. The disorderly intensification of agriculture results in erosion, losses and exhaustion of soil nutrients, abandonment of the area, and opening of new agr...
The increase in water demand and droughts have exacerbated water inequalities and weakened the economy worldwide. Nonetheless, droughts alone do not justify the severity of water scarcity events, leading to public water rationing and restrictions. It is of paramount importance to obtain a better understanding of how public perceptions of and attitu...

Yet, previous studies have shown that catchments are not hydrologically isolated, and topographic limits often neglect the groundwater boundaries. Thus, studies on effective catchment ar...
This paper evaluates the calibration effectiveness for estimating monthly average flow using the SWAT model in a watershed located at Espírito Santo state in Brazil. Six methodologies were tested, which differ from each other by varying calibration parameters, size of historical series and number of sub-basins associated with the process. SWAT-CUP...
Considering the economic and environmental damages caused by soil loss, it is clear the necessity of information about the effect that vegetation has on soil loss rate. The present paper uses the Revised Universal Soil Loss Equation with the objective of investigating soil loss under a native vegetation recovery (Atlantic Forest) and present condit...
Purpose
The most common methodology to estimate erosivity is using rainfall data obtained from rain monitoring stations. However, the quality of this estimation may be compromised due to low density, operational problems and maintenance cost of rainfall monitoring stations, common problem encountered in developing countries such as Brazil. The obje...
In-situ hydrological monitoring is essential for a proper decision-making process and modelling. Efforts have been made in Brazil to carry out field activities at the basin scale, but how complete and comprehensive are those studies? Where are they located? How long have they been carried out? What are the main findings? To answer these questions,...

Modelos hidrológicos, como o Soil and Water Assessment Tools (SWAT), são poderosas ferramentas para o gerenciamento de recursos hídricos. Entretanto, seu uso depende de muitos dados de entrada, comumente oriundos de bases internacionais e nacionais não realísticas. Dentre os dados de entrada, informações pedológicas em níveis regionais e locais são...
The uncertainties present in hydrological models have made them difficult and often impossible to apply. This work evaluated the sensitivity of input parameters in the SWAT model used for the modeling of average monthly flow-discharge in the Jucu River Basin, located in the southeast portion of the state of Espírito Santo, Brazil. Sensitivity analy...
Landslide is a disasters typology that result in serious material and immaterial damage for society. In order to initiate the research on factors which may influence landslides in the Guandu river basin (ES), secondary data were taken from landslide scars and correlated to six physiographic factors: distance to roads, distance to rivers, slope , ra...
Soil loss estimation in a rural watershed using the revised universal soil loss equation Abstract Soil loss, caused by the impact of raindrops and shear stress from the runoff, is a natural process of particle detachment which has worsened in the last century due to anthropogenic activities. Thus, the revised universal soil loss equation was couple...
