Hydraulic analysis of El Mahmoudia canal

Abstract

Egypt is facing increasing challenges in the water sector driven by the increased demand for water and increased pressures on the water resources of the River Nile. Due to the water challenges in Egypt, a number of integrated water management projects are starting to take place in order to improve the irrigation and drainage management and to increase the efficiency of irrigated agricultural water use and services. One of the projects adopted by the Ministry of Water Resources and Irrigation to face this problem is the Integrated Irrigation Improvement and Management Project in old lands to increase the efficiency of water use and achieve the optimum benefit. The main objective of the present paper is to study the hydraulic analysis of El Mahmoudia canal which is an important canal in the West Delta. The canal feeds Alexandria and El Beheira governorates with drinking and industrial demands in addition to irrigating about 120,000 Hectares. The results of a hydraulic model study are presented in this paper in order to identify the most effective physical interventions. An ISIS one dimensional hydraulic model was used to integrate the canal supplies and demands to assess the sensitivity of the water balance and canal performance to trends in demands. The canal is used to meet demands from Alexandria and hence the growth in municipal demands has been an important constraint on the management of water levels in the canal. The study has been developed to explore the sensitivity of the canal to key assumptions and parameters and therefore provides a valuable tool for establishing a strategy for on-going canal monitoring and a framework for managing the dynamics in water resources.

The pieces of the smallholder puzzle: The add‐in role of farmers' characteristics in irrigation improvement projects in the old lands of Egypt

“…Such impact assessments are often grounded in assorted sampling methods that focus on representative areas. Some of them indicate that their views rest on a sole case of the study area and are not meant to draw any general conclusion (El-Agha et al, 2011;Moghazy et al, 2014;Osman, Bakeer, et al, 2016). Others attempt to capture a larger picture and reflect on the overall situation of areas developed under irrigation improvement programmes (Depeweg & Bekheit, 1997;Elshorbagy, 2000;Abou Kheira, 2009;Water Management Research Institute, 2009;Kotb & Boissevain, 2012;Dutta, 2013;Mostafa & Fujimoto, 2015;Awwad et al, 2016;Molle et al, 2016).…”

Ecoepidemiology and Potential Transmission of Vibrio cholerae among Different Environmental Niches: An Upcoming Threat in Egypt

“…Sites 5 and 6 comprise the northwest to the Rosetta branch, where the El-Mahmoudeya canal runs about 77 km to meet the freshwater drinking and irrigation demands of several municipal, agricultural, and industrial activities as well as fisheries in El-Behaira ( Figure 5 , site 5) and Alexandria provinces, Egypt ( Figure 5 , site 6). In the Rosetta Estuary, the freshwater of the Nile ends 30 km upstream of the sea, where it releases excess water into the Mediterranean Sea [ 50 , 51 ].…”

Hydraulic Performance of Improved Irrigation System

“…In the third scenario, each valve will irrigate the served area in two consecutive days. Table (6) show the schedule of all valves of mesqa no. 1for the three scenarios of operation for 14 hours of operation per day.…”

“…Hydraulic models can be used to simulate the flow depth and discharge in irrigation canal network over space and time and thereby can help in understanding the hydraulic behavior of such system, Kumar et al [4]. Many researchers studied one-dimensional free surface flow with a spatially varied discharge, among them are Moghazy et al [6], Zerihum [16]. Misra [5] developed a mathematical model for the analysis of spatially varied flow in an irrigation canal.…”
