Résumé partiel
A linear-dynamic programming model capable of determining the optimal allocation of a multi-aquifer system and crop production in Al-Hassa area was developed and tested. The multi-aquifer system was visualized as a bi-aquifer system including : Neogene-Dammam, and Umm-Er-Radhuma. Most emphasis was given to development of the Umm-Er-Radhuma aquifer. The linear-dynamic programming model consisted of three interrelated steps : i)a parametric linear programming model step (PLP) ; ii)a groundwater flow model step (GF) ; and iii)a dynamic programming model step (DP). The main objective of the study was to develop and test a preliminary model that could be used to determine the most efficient use of the multi-aquifer system for crop production in Al-Hassa area. The model was tested with surface, sprinkler, and trickle irrigation systems. More specifically, this study attempted to : i)determine the optimal crop mixes that would give the highest annual net social benefits ; and ii)determine the consequences of the future development on the piezometric heads in Al-Hassa area ; and iii) determine the optimal temporal investment and resource utilization decisions that give the highest discounted net social benefits.
