Generalizability of machine learning models and empirical equations for the estimation of reference evapotranspiration from temperature in a semiarid region [PDF]

Anais da Academia Brasileira de Ciências
The Penman-Monteith equation is recommended for the estimation of reference evapotranspiration (ETo). However, it requires meteorological data that are commonly unavailable.

Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

Hydrological Processes, Volume 40, Issue 2, February 2026.
Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.

Explaining the evaporation paradox in Jiangxi Province of China: Spatial distribution and temporal trends in potential evapotranspiration of Jiangxi Province from 1961 to 2013

International Soil and Water Conservation Research, 2016
Evaporation acts as an important component and a key control factor in land hydrological processes. In order to analyze the trend of change on potential evapotranspiration from 1961 to 2013 and to discuss the existence of the evaporation paradox in ...

Changes in Dominant Streamflow Drivers as Network‐Scale Flow Regime Shifts From Intermittent to Ephemeral Across a Multi‐Year Drought

Hydrological Processes, Volume 40, Issue 2, February 2026.
Spatial variability in surface water activation and persistence decreased with ongoing drought. The importance of landscape attributes in explaining surface water presence decreased throughout the drought. Flow activation events after several years of drought were more closely associated with precipitation event characteristics than antecedent storage ...

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

Irrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

A new approach to estimating Mean Flow in the UK [PDF]

, 2002
Traditionally, the estimation of Mean Flow (MF) in ungauged catchments has been approached using conceptual water balance models or empirical formulae relating climatic inputs to stream flow. In the UK, these types of models have difficulty in predicting

Evaluation of CERES‐Maize Model for Predicting Yield, Evapotranspiration, Water Productivity and Drought Stress Indices Under Center Pivot, Subsurface Drip and Furrow Irrigation Systems With Different Irrigation Levels Simultaneously

Irrigation and Drainage, Volume 75, Issue 1, Page 372-389, February 2026.
ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Efficiency of methods for calculating class A pan coefficients to estimate evapotranspiration reference

Pesquisa Agropecuária Tropical, 2013
The class A pan coefficients (Kp) can be determined with several methods, most based on wind speed, relative humidity and conditions and extension of the border which circles the pan.

Long term trends of stand transpiration in a remnant forest during wet and dry years [PDF]

, 2008
Daily and annual rates of stand transpiration in a drought year and a non-drought year are compared in order to understand the adaptive responses of a remnant woodland to drought and predict the effect of land use change.
