IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Mathematical simulation of agriculture drainage water quality and quantity and its effect on el-nobaria canal
Author : S.A.K. HASSANIN1
ABSTRACT
El-Nobaria canal irrigates 1.076*106 feddans, in which eight potable water intakes take their water from it which
suffers from pollution by agriculture drainage water at seven locations. A 59% of such drainage water (DW) is
coming from ElNasr-3 main drain which tends to cause a deterioration of El-Nobaria canal water quality
downstream its outfall feeding all intakes (seven potable intakes and several branches) locating downstream km
(52,960) on El-Nobaria canal. The DRAINMOD/ DRAINMOD-N/ DRAINMOD-S models have been tested at the
field/field block scale using the field data of 2006/07 and 2007/08 to simulate outflow discharge, salinity and
nutrient load at catchment¡¯s agricultural outlets of El-Delengat Extension drain, El-Bostan drain, ElNasr-3 main
drain, and ElNasr-1 drain. Five measures are used to justify precision of the simulation results. A surface water
quality model, QUAL2K, has been calibrated and validated on El-Nobaria canal according to the field data during
summer 2007 & winter 2008, respectively. The study concentrated on salinity (TDS), nitrate-nitrogen (NO3-N), and
TN. The water quality of El-Nobaria canal was investigated to estimate the impact of drain discharged on its
quality. A proposed drainage reuse scenario is presented in this study to improve the water quality in El-Nobaria
canal & its branches especially at the potable water intakes.
