Most available hydraulic models presently used consider unit width approach in the design which does not exactly reflect the flow process in level basins. Selected surface irrigation simulation software based on zero-inertia models and mathematical models based on volume balance approaches were studied and compared with the experimental results for their accuracy in simulating the actual flow process in the basins. Zero-inertia models were found better in simulating the advance characteristics, while volume balance approaches performed equally well in predicting the time of application and percolation losses. An approach using combination of zero-inertia and volume balance, was suggested wherein advance characteristics derived from zero inertia may be directly used with volume balance approach for computing the management parameters.
