Multilevel Approach for Optimizing Land and Water Resources and Irrigation Deliveries for Tertiary Units in Large Irrigation Schemes. I: Method
(American Society of Civil Engineers, 2005)This paper presents the area and water allocation model (AWAM), which incorporates deficit irrigation for optimizing the use of water for irrigation. This model was developed for surface irrigation schemes in semiarid ... -
Multilevel Approach for Optimizing Land and Water Resources and Irrigation Deliveries for Tertiary Units in Large Irrigation Schemes. II: Application
(American Society of Civil Engineers, 2005)The resource allocation model, area and water allocation model, incorporates the concept of deficit irrigation through a variable depth irrigation approach, VDI. It uses this to allocate land and water resources optimally ... -

Multilevel Calibration of Furrow Infiltration and Roughness
(American Society of Civil Engineers, 2005)A stepwise multilevel scheme is developed to sequentially calibrate infiltration and roughness parameters for free-draining furrow irrigation systems. The scheme is one dimensional at each level, thereby simplifying ... -
Influence of Loss Model on Design Discharge of Homogeneous Plane
(American Society of Civil Engineers, 2005)By applying the kinematic wave method to a homogeneous, rectangular overland plane, the influence of the constant and proportional-loss models on the design discharge are examined. The examination shows that with the use ... -
Using Modified Bellani Plate Evapotranspiration Gauges to Estimate Short Canopy Reference Evapotranspiration
(American Society of Civil Engineers, 2005)Modified Bellani plate atmometer has been offered as an alternative and simpler technique to combination-based equations to estimate evapotranspiration (ET) rate from green grass surface. However, there is a lack of ... -
Coupled Surface-Subsurface Flow Model for Improved Basin Irrigation Management
(American Society of Civil Engineers, 2005)The availability of a process-based coupled surface-subsurface model can lead to improved surface irrigation/fertigation management practices. In this study, a one-dimensional zero-inertia model is coupled with a one-dimensional ... -
Multiple-Model Optimization of Proportional Integral Controllers on Canals
(American Society of Civil Engineers, 2005)Canals or open channels that convey water often consist of pools in series separated by control structures. Successful implementation of water-level control with these structures using decentralized proportional integral ... -
Hydraulic Analysis of Multidiameter Center-Pivot Sprinkler Laterals
(American Society of Civil Engineers, 2005)Analytical equations for direct hydraulic analysis of a multidiameter center-pivot lateral with and without an end gun were developed. The pressure head profile along the multidiameter center-pivot lateral is described by ...
