Abstract
Al Msharah River is one of the main controlled feeders of Al
Huwayza Marsh in addition to its importance in irrigation of the
nearby agricultural areas. A study for evaluating the hydraulic
performance of this river has been carried out to develop the ability of
the river to accommodate the increase of the required discharge for
feeding the marsh and agricultural projects. Achieving this objective
require carrying out field hydrological measurements, stage and
discharge, at a number of stations distributed along the river for period
of six months. A steady one dimensional hydraulic model has been
prepared to simulate the flow in this river using the HEC-RAS
software (Version 3.1.3). The calibration and verification processes of
the model have been carried out by making use of the field
measurements. The maximum allowable discharge of this river for the
present conditions has been found and the failure, flood, locations
have been specified along the river. The required cross sections to
develop the capacity of the river have been found considering the
marsh and agricultural requirements.
