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...
Droughts and floods are natural phenomena in the Amazon, arising from spatial temporal variability of rainfall distribution. However, anthropogenic climate change forest degradation, summed to large-scale climatic events, have intensified their frequency, intensity onset, pushing Amazon region a critical tipping point. The Madeira River, largest most significant tributary is particularly vulnerable these extremes. Notable droughts 2005, 2010, 2015-2016 2023-2024, alongside major 2014 2021,...
Soil and water conservation is a pressing global challenge, exacerbated by land use changes, cover transitions, extreme rainfall events. Rainfall plays pivotal role in soil erosion due to its ability detach transport particles. Understanding spatial temporal variability critical for devising effective strategies. erosivity studies typically focus on the RUSLE R-factor quantify monthly annual trends. However, these broader timescales may overlook event-based dynamics captured metrics like...
The heavy rains and floods that struck southern Brazil in May 2024 highlighted the vulnerability of population to extreme hydrological disasters, resulting 176 confirmed fatalities, around 40 people missing, over 422,000 individuals displaced. Flood Early Warning Systems (FEWS) are crucial tools for reducing flood-related damage fatalities. accurate prediction flood peaks their timing is essential effective evacuation planning. This study proposes an enhanced Long Short-Term Memory (LSTM)...
Effective monitoring and forecasting of flood events are key aspects early warning systems, especially in areas susceptible to frequent floods. In this context, Artificial Intelligence (AI) techniques have proven be a strong tool for enhancing such systems because they can capture non-linear processes genesis. AI models make accurate predictions with minimum processing time, thus providing alternative nowcasting. However, the quality quantity stations black-box nature machine learning (ML)...
ABSTRACT Since prolonged droughts have impacted Atlantic forests in Southeastern Brazil, further investigations to understand the effects of such stressful conditions their hydrological behavior are required. This study aimed assess changes water balance a semi-deciduous forest remnant and how responds droughts. The Standardized Precipitation-Evapotranspiration Index was applied identify (from 1961 2019) severity both year summer scales. Drought impacts on actual evapotranspiration,...
Information on evapotranspiration (ET) has the potential to clarify drought’s effects water balance of natural ecosystems. Here, we use a 6-year dataset present daily ET trends under different drought conditions in seasonally dry Atlantic Forest southeast Brazil as well environmental and biophysical controls. Generalized linear models (GLMs) were applied highlight main controls ET. Significant differences for not found (near normal, moderately dry, severely dry). responded positively net...
The interaction between the forest canopy and precipitation is a fundamental process for understanding hydrological cycle in forests. Physical models have been applied to estimate water interception, their efficiency has tested based on metrics used assess models. For eucalyptus plantations Brazil, more studies are needed rainfall interception model. Thus, we calibrated Gash model using two complete years of observation plantation southeastern Brazil. model’s parametrization was conducted 17...
This study was carried out in an Atlantic forest remnant Southeastern Brazil and aimed to spatially model the soil water content (SWC) net precipitation (NP) on a monthly time scale assess spatial behavior of these hydrological variables different seasons. NP is defined by summing throughfall stemflow, which have been collected after each rain event accumulated monthly. Soil moisture measurements were up depth 1.00 m then integrated obtain SWC. The exponential semivariogram fitted for both...
The rainfall-forest canopy interaction can impact on the chemical and physical rain-water features is expected that different forests will have effects throughfall quality parameters. This study aimed (i) to compare variables observed in both gross precipitation measured two forest stands (Atlantic semideciduous remnant - AFR, a Eucalyptus urograndis plantation EUP). Each stand was monitored with 8 internal rain-gauges one external rain-gauge, encompassing period from March 2015 2016....
O planeta vem sofrendo diversas mudanças no clima ao longo das décadas, sendo alvo de estudo para diversos pesquisadores em vários locais mundo. Dentre as clima, destaca-se aumentos na temperatura do ar devido, por exemplo, lançamento concentrações cada vez mais elevadas gases efeito estufa ocorrido nos últimos anos, oriundos principalmente atividades antrópicas, promovendo a nível global e regional ar. Também, tem-se observado alterações regimes pluviométricos alguns locais. Neste contexto,...
