Oral Presentation

Introduction

Surfactant and foam processes have been widely used in enhanced oil recovery from the petroleum-bearing geological formations [1, 2] and in-situ subsurface remediation from shallow formation and aquifer [3, 4].
This study investigates the potential of using surfactant and foam processes for the in-situ remediation of shallow subsurface NAPL phases within a field in a US/Korea...

311. The importance of accurate evapotranspiration forecast for crop irrigation: A global sensitivity analysis of two model case studies

Oral Presentation

A reliable forecast of potential evapotranspiration (ET$_0$) and precipitation can be used for precision crop irrigation. A multi-objective evolutionary algorithm (MOEA) optimization followed by a sensitivity analysis (SA) of a crop model (HYDRUS-1D) for two case studies was performed in order to assess the crop model sensitivity to weather forecast accuracy. A $\pm$5 % of ET$_0$ relative bias...

507. Multiscale Modeling of Direct Contact Membrane Distillation: Macroscopic Modeling and Pore Scale Modeling

Oral Presentation

Membrane distillation (MD) using porous hydrophobic membranes finds applications in various areas such as desalination of seawater, industrial wastewater treatment, and pharmaceutical separation of mixtures. In this study, a direct contact membrane distillation (DCMD) module with commercially available polytetrafluoroethylene (PTFE) membranes (GE-Osmonics/0.22um and MS-3010/0.45um) is...

559. The impact of drought-induced root and root hair shrinkage on root-soil contact

Mr Patrick Duddek (ETH Zurich, Physics of Soils and Terrestrial Ecosystems)

(MS2) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Increasing the contact area between roots and soil, root hairs are hypothesized to be a key plant strategy facilitating nutrient and root water uptake. Although future agriculture will have to deal with an increasing water and nutrient deficiency, there is still a lack of knowledge regarding root responses to soil drying. In particular, the effect of drought stress on root-soil contact remains...

711. Modelling rhizosphere water movement in whole plant models

Daniel Leitner (Simwerk)

(MS2) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Plant productivity is directly influenced by water and nutrient uptake. Therefore, functional-structural root models need to accurately describe rhizosphere processes. Such models will enable better agricultural management strategies and improved root trait selection for plant breeding. Due to their complexity functional-structural root models are hard to analyse. In Schnepf et al. (2020)...

282. EUTROPHICATION CONTROL TREATMENTS AND SEDIMENT POROSITY

Dr Anne M. Hansen (Mexican Institute of Water Technology)

(MS2) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Different land uses and wastewater discharges from point and diffuse emission sources result in accumulation of nutrients, or eutrophication of lakes and reservoirs, and water quality not meeting standards for different uses. Consequently, 70% of the approximately 300 lentic water bodies monitored in Mexico are in a eutrophic or hypereutrophic state [1]. Different methods have been proposed...
