Water balance complexities in ephemeral catchments with different land uses: Insights from monitoring and distributed hydrologic modeling [PDF]

open access: yes, 2016
Although ephemeral catchments are widespread in arid and semiarid climates, the relationship of their water balance with climate, geology, topography, and land cover is poorly known.

Analysis of the Accuracy Comparison of Five Different Models of Valiantzas Equation in the Estimation of Reference Evapotranspiration [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Evapotranspiration is one of the most important factors in hydrological cycle. Potential evapotranspiration is used to design in irrigation and drainage networks and hydrological studies (Davis & Dukes, 2010).

Mapping evapotranspiration variability over a complex oasis-desert ecosystem based on automated calibration of Landsat 7 ETM+ data in SEBAL [PDF]

open access: yes, 2019
Fragmented ecosystems of the desiccated Aral Sea seek answers to the profound local hydrologically- and water-related problems. Particularly, in the Small Aral Sea Basin (SASB), these problems are associated with low precipitation, increased temperature,

potential evapotranspiration

open access: yes, 2014
Contained within the 4th Edition (1974) of the Atlas of Canada is a set of three maps relating the effects and dependency of vegetation on environmental variables. One map shows the average annual potential evapotranspiration in inches from ground and plant surfaces for areas where there is a continuous vegetation cover and sufficient soil moisture for

Change in Aridity Index in the Mediterranean Region under Different Emission Scenarios

open access: yesEnvironmental Sciences Proceedings, 2023
In the present study, the spatial and temporal variability of the Aridity Index (AI) in the Mediterranean region during the 30-year period 1971–2000 is analyzed. The analysis is performed on a decadal timescale.

Optimal irrigation water allocation using a genetic algorithm under various weather conditions [PDF]

open access: yes, 2014
Growing water scarcity, due to growing populations and varying natural conditions, puts pressure on irrigation systems, which often are the main consumptive water users.

Evapotranspiration Mapping for Forest Management in California's Sierra Nevada [PDF]

open access: yes, 2020
We assessed the response of densely forested watersheds with little apparent annual water limitation to forest disturbance and climate variability, by studying how past wildfires changed forest evapotranspiration, and what past evapotranspiration ...
