Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]

open access: yes, 2020
The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

Crop coefficients, growth rates and quality of cool-season turfgrasses [PDF]

open access: yes, 2015
Determination of crop coefficients (Kc), the ratio between actual (ETa) and reference evapotranspiration (ET0), is necessary to schedule irrigation. Our objective was to determine Kc, turf quality and growth rate under daily irrigation to field capacity (

Deriving potential evapotranspiration from satellite-based reference evapotranspiration, Upper Tekeze Basin, Northern Ethiopia

open access: yesJournal of Hydrology: Regional Studies, 2022
Study region: Zamra catchment, Upper Tekeze Basin, Northern Ethiopia. Study focus: Direct field estimates of potential evapotranspiration (PET) remain a challenge, because they are expensive and have limited spatial representativeness.

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.

Impact of potential climate change on plant available soil water and percolation in the Upper Danube basin [PDF]

open access: yes, 2010
The soil root zone of the land surface provides plants with water for transpiration and therefore biomass production and its excess water percolates downwards and ultimately recharges the groundwater aquifers.

Urbanization Effects on Reference Evapotranspiration [PDF]

open access: yesJournal of Korea Water Resources Association, 2007
The effects of climatic changes owing to urbanization, geographical and topographical conditions on Penman-Monteith reference evapotranspiration, and energy and aerodynamic terms of Penman-Monteith reference evapotranspiration have been studied. In this study, 56 climatological stations including the Seoul metropolis in South Korea have been selected ...

Development of the crop coefficient for capsicum (Capsicum annum L.) under protected structures

open access: yesJournal of Agrometeorology, 2016
The study was undertaken to determine the crop water requirement and crop coefficient for capsicum (Capsicum annum L.) at plasticulture farm of CTAE, Udaipur, Rajasthan under four small protected structures; (i) shednet house (ii) insectnet house (iii ...

Radiation Balance and Partitioning of Latent and Sensible Heat Fluxes Over a Lime Orchard in Eastern Amazon [PDF]

open access: yesRevista Brasileira de Meteorologia, 2023
We investigate the balance of radiation and energy over a lime orchard in Eastern Amazon and how it relates to environmental conditions. We found that lime trees aged between 6 and 7 years old reflect 11.0% to 14.5% of incoming shortwave radiation, and ...

Assessment of crop water requirement of field pea (Pisum sativum L.) in foothills valley areas of Manipur, North East India

open access: yesJournal of Agrometeorology, 2021
The purpose of this study was to assess the evapotranspiration in field pea (Pisum sativum L.) in foothills valley areas of Manipur using the Hargreaves-Samani equation to predict the plant water demand. The crop coefficient (Kc) values ranged between 0.
