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.
