A theory for the design of conveyance systems, synthesizing with it the operation and management and set in an interdisciplinary mode is proposed. The theory involving eleven steps is required in the development of solutions for six basic problems hitherto inadequately addressed. These solutions are liven in the following six modules of the dissertation: -Optimal Turnout Area Module -Turnout Area Water Requirement Module -Project Scale Farm Design Module -Ground Water Interaction Module -Water Issue Strategy Module -Hydraulic Simulation Module.
