Abstract
Hydraulic simulation models could be suitable tools for understanding the hydraulic characteristics of irrigation systems. In this study HEC-RAS model will be tested in terms of error estimation and used to determine canal capacity potential. Thiba main canal reach in Mwea Irrigation Scheme (MIS), approximately 100 Kilometers North East of Nairobi City was selected. MIS being a model scheme in the country, its contribution to food security and growth of the sector is inherent. Sluice gates and trapezoidal canals are amongst the structures in the Thiba main canal reach system. HEC-RAS model will be calibrated and validated using two sets of observed discharges, gate openings and water levels. Due to its minimal estimation errors, HEC-RAS model would be appropriate in evaluation of canal hydraulics steady state conditions to improve on scheme performance.
