Agrohydrology and Biophysical Modelling

Currently, i am working on two research projects as the main PI.1. Development of a data driven nitrate leaching hazard index and BMP assessment tool for California, USA.2. Development of a pesticide fate and transport model that simulates pesticide concentrations in the groundwater for different scenarios of pesticide use

Working for the research project “Multiscale Interfaces in Unsaturated Soil (MUSIS)“ funded by the German Research Foundation (DFG). Describing the evaporative movement of soil water towards the soil-atmosphere interface with one-dimensional effective continuum-scale process models can be a valid approach under some conditions, but may lead to erroneous flow predictions under certain circumstances. The aim of this subproject is to explore in close collaboration with the partner projects… Show more Working for the research project “Multiscale Interfaces in Unsaturated Soil (MUSIS)“ funded by the German Research Foundation (DFG). Describing the evaporative movement of soil water towards the soil-atmosphere interface with one-dimensional effective continuum-scale process models can be a valid approach under some conditions, but may lead to erroneous flow predictions under certain circumstances. The aim of this subproject is to explore in close collaboration with the partner projects in the Research Group MUSIS (DFG FOR 1083) validity limits of the Richards equation for describing bare soil evaporation in particular during stage-two evaporation, where the soils unsaturated hydraulic conductivity and vapor diffusion in soil dominate the evaporation process.

Working for the research project "Hydraulic Processes and Properties of Partially Hydrophobic Soils" funded by the Niedersächsische Technische Hochschule (NTH).Soils that repel water are considered hydrophobic. In this project, we aim to obtain a quantitative description of the processes that govern water transport in hydrophobic soils. Experimental investigations about water in hydrophobic porous media will be combined with inverse numerical modelling of water transport.

In this project, we aim to obtain a quantitative description of the processes that govern water transport in hydrophobic soils. Experimental investigations about water in hydrophobic porous media will be combined with inverse numerical modelling of water transport. The project is located in the field of environmental sciences, and will contribute to knowledge about water and energy fluxes in the soil-plant-atmosphere continuum. This will help to assess the impact of climate change on the water regime of soils, with its consequences for ground water renewal, surface runoff, and vegetation dynamics. Show less
