Pascal Benard: Projects

Completed Projects

  • A pore network model of soil hydrophobicity (DFG CA921/4-1)
    The objective of the project is to improve our understanding of the physical mechanisms that cause some soils to turn water repellent. Our hypothesis is that the microscopic heterogeneity of hydrophobic compounds explains why at given water contents and soil organic matter a soil turns suddenly from hydrophilic to water repellent. Such criticality can be explained using a percolation approach. [Details]

  • Rhizosphere wettability and implications for water availability to plants (VWZN 3152)
    This study deals with water flow through the rhizosphere during repeated drying and wetting scenarios, simulating the impact of drought events and irrigation. We focus on the effects of mucilage on water repellency in the rhizosphere. Our aim is to quantitatively predict the occurrence of water repellency in this region. Two modelling approaches will be combined to simulate the rhizosphere water dynamics. This project is realized in cooperation with Prof. Dr. Rony Wallach (Hebrew University of Jerusalem). Project Managers: Prof. Dr. Andrea Carminati, Prof. Dr. Rony Wallach Coworkers: Pascal Benard (PhD student), Ibukun Medahunsi (PhD student) [Details]
