Summary

To calculate the water balance of an agricultural used landscape based on a deterministic site model one is faced with many soil, weather and plant parameters used within the nonlinear process models describing the water transport in the unsaturated zoneof the soil. Investigating évapotranspiration and ground water recharge our mathematical concept consists of classifying model soil columns (ms) with prescribed texture by régionalisation indicators (ri ε ℜn). The grouping tool is hierarchical cluster analysis by several (dis-)similarity measures.
