Knowledge of the way perturbations propagate and/or attenuate along free-flow irrigation delivery systems is crucial for monitoring and effectively operating a system. With this knowledge sections of the canal system which are identified as sensitive to flow perturbations should be targeted for more frequent inspection and operational decisions than others. The steady-state hydraulic approach f...

Field crop production must adapt to the challenges generated by negative consequences of climate change. Yield loss caused abiotic stresses could be counterbalanced increasing atmospheric CO2 concentration, but C3 plant species and varieties have significantly different reactions CO2. To examine responses wheat, barley oat enrichment in combination with simulated drought, a model experiment was...
