| Abstract | Irrigation water management is becoming more important, as
irrigation competes for limited water supplies, energy, and land as
throughout the world degrade and decline in productivity, because of poor
water management. Surface water resources of Pakistan are also limited.
However an underground water storage of immense potential is available
for exploitation. A significant increase in agricultura l production is
anticipated by irrigation management utilizing both the surface and
ground water resources.
The command area of the Rakh Branch Canal in the Lower Rechna Doab
has been selected as t he case study for which crop water requirements for
ten-day periods have been computed considering the existing cropping
pattern. The computation of t he reference crop evapotranspiration has
been done by Penman Method using the measured climatic data. Irrigation
water requirements are computed deducting effective rainfall as we ll as
ground water contribution from the shallow water table and then by adding
the operational wastes and deep percolation losses including routine
leaching. The overall irrigation efficiency is considered as 40 percent.
The ten-day irrigation water supplies are worked out from historic canal
deliveries at its headworks and from ground water reservoir with reference
to pumpage of public and private tubewel ls. I n light of computed
requirements and water availability, a cropping pattern with 150 percent
cropping intensity has been proposed for the command area. Irrigation
scheduling based on conjunctive use of surface and ground water aiming
at the delivery of the adequate amounts of water at the time of crop needs
for proposed cropping pattern has been suggested. |
