Abstract

SIRMOD model is more suitable tools for evaluation of irrigation systems that must be tested and evaluated before use in practice. Sensitivity of SIRMOD to input parameters in three solution methods of Saint- Venant equation was evaluated with ±25% of input parameters variation. SENSITIVITY ANALYSIS results was shown, model is more sensitive to input parameters in ADVANCE phase and RUNOFF volume than other parameters (Slope, roughness coefficient and furrow geometry). Model in infiltrated water volume is more sensitive to infiltration equation coefficient and inflow respectively, than other input parameters. SIRMOD isn't sensitive to solution methods of Saint-Venant equation. Sensitivity of model is variable with soil type. The percent of input parameters variation isn't effective in sensitivity order. Therefore, the parameters must be measured with maximum accuracy consist on inflow and soil infiltration coefficients.
