FUSSIM2 version 5; new features and updated user's guide

Research output: Book/ReportReportProfessional

Abstract

FUSSIM2 is a two-dimensional simulation model for describing movement of water, solute transport and root uptake of water and nutrients in partially saturated porous media. It was documented in 1998. Since then new features have been included that aredescribed in the current report. The new features include: extension to the van Genuchten-Mualem description of the physical properties of the porous medium, reduction of evaporation of water at the soil surface, runoff, the Vimoke drain concept, phosphate adsorption and phosphate fixation, non-zero sink nutrient uptake, root growth described as a diffusion process, nitrification and denitrification, and soil temperature. Furthermore, a version in cylindrical coordinates is available, FUSSIM2 is coupledwith the organic-matter model MOTOR, and an expo-lineair growth and demand module is included in FUSSIM2 for special situations. This report includes an updated users' guide.
