Differentiable, learnable, regionalized process-based models with physical outputs can approach state-of-the-art hydrologic prediction accuracy [PDF]

Water Resources Research, 58 (2022), 2022
Predictions of hydrologic variables across the entire water cycle have significant value for water resource management as well as downstream applications such as ecosystem and water quality modeling. Recently, purely data-driven deep learning models like long short-term memory (LSTM) showed seemingly-insurmountable performance in modeling rainfall ...

Estimating potential reference evapotranspiration using time series models (case study: synoptic station of Tabriz in northwestern Iran)

Applied Water Science, 2022
The potential evapotranspiration is considered as an important element of the hydrological cycle, which plays an important role in agricultural studies, management plans of irrigation and drainage networks, and hydraulic structures.

Controls on the diurnal streamflow cycles in two subbasins of an alpine headwater catchment [PDF]

, 2015
In high-altitude alpine catchments, diurnal streamflow cycles are typically dominated by snowmelt or ice melt. Evapotranspiration-induced diurnal streamflow cycles are less observed in these catchments but might happen simultaneously.

Crop Evapotranspiration [PDF]

Agronomy, 2019
Evapotranspiration (ET) is one of the largest components of the water cycle, and accurately measuring and modeling ET is critical for improving and optimizing agricultural water management. However, parameterizing ET in croplands can be challenging due to the wide variety of irrigation strategies and techniques, crop varieties, and management ...

An overview of uncertainties in evapotranspiration estimation techniques

Journal of Agrometeorology, 2023
Accurate estimation of evapotranspiration (ET) is essential both at the regional and local scales for many management tasks. Numerous methods for estimating ET with various complexities and combinations exist which may be broadly classified as direct ...

Consistency between hydrological model, large aperture scintillometer and remote sensing based evapotranspiration estimates for a heterogeneous catchment [PDF]

, 2012
The catchment averaged actual evapotranspiration rate is a hydrologic model variable that is difficult to quantify. Evapotranspiration rates - up till present - cannot be continuously observed at the catchment scale.

Impacts of climate change on groundwater droughts by means of standardized indices and regional climate models [PDF]

Journal of Hydrology 603 (2021) 127154, 2022
This paper investigates the impacts of climate change on groundwater droughts making use of regional projections and standardized indices: the Standardized Precipitation Index (SPI), the Standardized Precipitation Evapotranspiration Index (SPEI) and the Standardized Groundwater Index (SGI).

Re-appraisal of the global climatic role of natural forests for improved climate projections and policies [PDF]

Frontiers in Forests and Global Change 6:1150191, 2023, 2023
Along with the accumulation of atmospheric carbon dioxide, the loss of primary forests and other natural ecosystems is a major disruption of the Earth system causing global concern. Quantifying planetary warming from carbon emissions, global climate models highlight natural forests' high carbon storage potential supporting conservation policies ...
