Land and water resources allocation policies are imperative for sustainable natural resources management of an irrigation project. The groundwater resource of the irrigation system is very
complex and dynamic in nature. For understanding and managing these resources for future policy
development and implementation, mathematical modeling approach is highly essential. Therefore,
a three-dimensional transient groundwater flow model is developed using MODFLOW for
simulating hydraulic head, using available well data and general hydro-geological information. The
layer property flow (LPF) package of the MODFLOW model is used in the present study. The
developed model is applied to the Hirakud canal command (416 km2) of western Odisha. Transient
calibration of the groundwater flow model is accomplished by varying model parameters
(horizontal and vertical hydraulic conductivity, specific storage, specific yield, and recharge rate)
by matching simulated hydraulic head distribution with the groundwater levels observed data for
the period January, 2005 to January 2006. Trial and error method is adopted in the present study for
the calibration. After calibration, groundwater model is utilized for verification of the optimal
water allocation policy. Keeping the values of calibrated parameter fixed, model is run with
changing agricultural water demand to develop various scenarios of groundwater withdrawal policy
guidelines for agricultural water management of the study area. Thus, the model study served the
purpose of proper utiliziation of the groundwater resources precisely in a sustainable manner and
policy implementation of the study area.
