HYDRODYNAMIC STUDY OF NILE RIVER USING 1D MODEL
Yasmeen Samir Sayed Hassaneen;
Abstract
Many studies to predict water surface profiles of Nile River downstream Aswan Dam were widely carried out. However, most of these studies were concerned to part of the river (single reach), with rare studies of the Nile River as a whole.
The study in hand was carried out to identify the occurred variations in water surface levels through the whole Nile river flowing in the Nile valley from downstream of Aswan Dam to upstream of the Delta barrages taking into consideration all hydraulic structures constructed through the river including barrages, bridges and lateral structures.
One dimensional mathematical model is built using HEC-RAS software, which was the most suitable to execute the Longitudinal water surface profile for a natural river channel. The daily records of flow discharges and the corresponding water surface levels in addition to the bathymetric survey along the four reaches in the year 2006 were utilized to predict the suitable manning’s coefficients to be applied to the hydraulic model to simulate the consequent river actual conditions.
For calibration process, a steady state simulation for each of the four reaches was conducted separately was built by passing the flows for high demand period (June), average demand period (April) and low demand period (January) which are:
