WP3: Bottom-Up approach by the 3D models

WP3: Bottom-Up approach by the 3D models : from micro-spatial heterogeneity to fluxes

Coordinator: Valérie Pot -Main Participants: Olivier Monga, Philippe Baveye, Ruth Falconer, Frédéric Hecht, Philippe Parneaudeau, Patricia Garnier , Claire Chenu, Wilfred Otten, Catherine Hénault, 75% Post-Doc, Ruth Falconer will spend one week in Paris.

Objectives:  The objectives are twofold:

1- to calibrate and validate the 3D models on the set of measurements of biodegradationobtained in WP1 under different micro-environmental conditions (i.e., different pore architectures, water contents, organic matter distributions) given by WP2 and with different decomposer communities (bacteria vs fungi).

2- to build and run simulation scenarios exploring contrasted micro-environmental conditions that were not tested in the experimental WP1. The inputs of the scenarios describing micro-spatial heterogeneities (3D maps of pore architectures, water contents, organic matter and decomposers distributions give by WP2) and their outputs being the simulated global fluxes at the core scale of CO2, N2O, µB, DOC will be given to WP2 and WP4, respectively.
