FORMATION TAPPED IN SHADCO WELLS
SECTION NO.3, SHOWING UMM ER RADHUMA
Irrigation Water Source
Cross Section showing Umm Er Radhuma Formation tapped in SHADCO wells
10. Sand Layer in Eastern Region is very thin With
a high infiltration rate of 30cm/hour.
Causes of Water logging in Irrigation Scheme.
1- Imprevious layer.
Excessive irrigation is required
because of high Evapotranspiration
rate
Due to excessive Irrigation, Water can not
percolate which results in the formation of
ponds in low lying areas.
Cross-section showing the Impervious Layer (Marl)
The preliminary excavation in several parts of
the project indicates a hard material
(hardpan) underlined the irrigation scheme and
causing the percolated irrigation water to rise
upwards forming water logged areas.
