A Comparative Study on the Water Quality of Two Nilotic Canals in the Delta of Egypt

Elsayed A Khallaf, Galal M, Mohammad Authman MN and Zaid RA

The River Nile branches into irrigation canals, which extends for many kilometers (40 km to 85 km), where each represents a semi-independent ecosystem. Of those, Bahr Shebeen and Alkhadraweya Canals are present in the Minufiya Governorate, and extend through out other governorates in the Delta of Egypt. Water Quality data included the following parameters: total hardness, total dissolved solids, electrical conductivity, dissolved oxygen, pH, Cl, Mg, Ca, Zn, Mn, PO4, Fe, NO3, and Cu. These parameters were examined and discussed, for significant relationships for each Canal. The favorability of each ecosystem for fish is examined, on the basis of fish growth condition. Subsequently, Water Quality Index was discussed for those Canals, and a WQI is suggested.
