Overview

What is he best known for?

The fields of study he is best known for:

  • Irrigation
  • Hydrology
  • Groundwater

His primary areas of investigation include Hydrology, Soil water, Water uptake, Soil science and Pressure head. His Soil water study combines topics from a wide range of disciplines, such as Atmosphere and Plant growth. His study in Soil science is interdisciplinary in nature, drawing from both Water balance, Sink and Evapotranspiration.

Water balance is a subfield of Geotechnical engineering that Reinder A. Feddes investigates. His Sink research is multidisciplinary, incorporating perspectives in Root function, Root system and Moisture. Reinder A. Feddes incorporates Pressure head and Hydraulic conductivity in his research.

His most cited work include:

  • A remote sensing surface energy balance algorithm for land (SEBAL)-1. Formulation (2024 citations)
  • Simulation of field water use and crop yield (1351 citations)
  • Simulation model of the water balance of a cropped soil: SWATRE (552 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Hydrology, Soil water, Soil science, Water content and Evapotranspiration. His study on Groundwater, Irrigation and Drainage is often connected to Transpiration and Pressure head as part of broader study in Hydrology. His work in the fields of Soil water, such as Hydraulic conductivity, Loam and Soil test, overlaps with other areas such as Water extraction.

His Soil science study integrates concerns from other disciplines, such as Water balance and Reduction. His study on Water content also encompasses disciplines like

  • Evaporation which connect with Atmospheric sciences,
  • Remote sensing and related Latent heat and Sensible heat. His work carried out in the field of Evapotranspiration brings together such families of science as Moisture and Soil physics.

He most often published in these fields:

  • Hydrology (37.63%)
  • Soil water (34.41%)
  • Soil science (26.88%)

What were the highlights of his more recent work (between 2002-2020)?

  • Hydrology (37.63%)
  • Evapotranspiration (18.28%)
  • Soil water (34.41%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Hydrology, Evapotranspiration, Soil water, Water content and Soil science. The concepts of his Hydrology study are interwoven with issues in Grassland and Soil horizon. Reinder A. Feddes merges Evapotranspiration with Simulation modeling in his study.

He has included themes like General Circulation Model and Aquifer in his Soil water study. His work in Water content addresses subjects such as Water balance, which are connected to disciplines such as Soil texture. The Hydraulic conductivity and Leaching research Reinder A. Feddes does as part of his general Soil science study is frequently linked to other disciplines of science, such as Water uptake, therefore creating a link between diverse domains of science.

Between 2002 and 2020, his most popular works were:

  • Water productivity analysis of irrigated crops in Sirsa district, India (90 citations)
  • Parameterizing the soil - water - plant root system (83 citations)
  • Increasing water productivity of irrigated crops under limited water supply at field scale (83 citations)

In his most recent research, the most cited papers focused on:

  • Irrigation
  • Hydrology
  • Groundwater

Reinder A. Feddes mostly deals with Hydrology, Evapotranspiration, Water content, Irrigation and Water balance. In his study, which falls under the umbrella issue of Hydrology, Soil gradation and Hydraulic conductivity is strongly linked to Soil horizon. Reinder A. Feddes integrates many fields, such as Evapotranspiration and Land cover, in his works.

The Water content study combines topics in areas such as Sugar beet, Sowing, Fodder and Irrigation district. In his study, Remote sensing is inextricably linked to Irrigation management, which falls within the broad field of Groundwater. Reinder A. Feddes is interested in Hydrus, which is a branch of Soil water.
