Applying Modern Surveying Techniques and Simulation Models for The Rehabilitation of Main Canals in Egypt: Case Study – El-Bagoriya Canal تطبیق تقنیات المسح الحدیثة ونماذج المحاکاة الهیدرولیکیة لإعادة تأهیل الترع الرئیسیة فی مصر دراسة حالة - قناة الباجوریة

Abstract

El-Bagoriya canal is a main canal in the Middle Delta and it is the main water source for West Kafr El-Sheikh irrigation directorate. As originally a natural canal, El-Bagoriya canal has specific characteristics that affected its hydraulic performance, and which resulted in a problem in conveying required water supply to downstream irrigation directorates. With the installation of two new municipal stations on the canal, there was a plan to dredge the canal inside El-Monofiya irrigation directorate to increase its hydraulic capacity. A research project was conducted to help the irrigation directorate implementing the dredging in the best way. The research activities included surveying the cross sections using modern surveying techniques, using ArcMap program to develop contour maps from the surveyed points and derive cross sections from these counter maps. The activities also included using the simulation model to check the original situation, the suggested dredging scenario, and the actual dredging. The results showed that the suggested dredging could improve the flow inside the investigated reach from 53.5 m3/sec to 64.5 m3/sec while maintaining minimum water slope inside the reach. Actual dredging could improve the flow inside this reach to 57.5 m3/sec while maintaining the same water slopes.
