Assessment of hydraulic changes due to construction of a barrage in the Shatt Al-Basrah canal using one dimension model (Mike 11)

Abstract

Shatt Al-Basrah is an artificial Canal, started in 1971 and completed in 1983. It was established to reduce flood and drain the excess water during the flood seasons, as a canal alternative to Shatt al-Arab during the Iran-Iraq war. It delivers water to the Zubair area and Al Faw town for agricultural purposes. A deterioration of the water quality of the canal was occurred due to many reasons; most importantly was the close of the canal at the junction of Garmat-Ali which is affected by the semidiurnal rhythm of the Arabian Gulf. There is a regulator located at about 22 km from the head of the canal. The main purpose of the canal is to control water drainage during flood and mitigating the effects on both sides land. In this paper the canal was simulated by the existence of controlled barrage on the water way, closed during the flood tide time and opened at the ebb tide. The simulation results after calibration of the mathematical model with field measurements, matched with high accuracy. The tidal effects on the canal can be determined, and the rehabilitation of the canal and water management in the surrounding areas can be preformed. The results indicate the sensitivity of the mathematical model to predict the measurements of water level, volume of water, flow speed of the current, discharge, downstream and upstream direction of discharge and the effect of tidal range at any point along the canal at the closure and opening of the regulator

Ecological study of zooplankton in the Shatt Al-Basrah canal, Basrah-Iraq

“…Shatt Al-Basrah river is an artificial canal opened in 1983 to transfer the flood water from Al-Hammar marshes into Khor Al-Zubair and then to the Arabian Gulf (Al-Aesawi, 2010). The canal is connected to the so called the third River, which is also an artificial canal constructed to carry waste irrigation waters from the middle and southern region of the Mesopotamia.…”

“…The canal is connected to the so called the third River, which is also an artificial canal constructed to carry waste irrigation waters from the middle and southern region of the Mesopotamia. Shatt Al-Basrah canal is located between (47º 45′ 00″ & 47º 49′ 00″ E) and (30º 18′ 00″ & 30º 39′ 00″ N), it started from Harrier at Qarmat-Ali, north of Basrah and runs south east to connect with Khor Al-Zubair (Al-Aesawi, 2010).…”

Total dissolved solids modeling in the Shatt Al-Basrah canal, using Mike 11

“…The inflow rate in the upstream of the canal in this period was about 60 m³/sec. The downstream tidal data for this period can be shown in Figure (3) (Al-Aesawi, 2010).…”

“…The hydrodynamic properties in Shatt Al-Basrah canal had been studied by Al-Aesawi (2010) by apply one dimensional model using Mike11 software. This work aims to simulate the variations of the hydrodynamics conditions and TDS distribution in the Shatt Al-Basrah canal in two different time periods by using one dimensional hydrodynamic model.…”

Simulation of Interaction Between Groundwater and Surface Water in Safwan-Zubair Area, South of Iraq

“…There are many studies conducted in this field (the interactions between groundwater and surface water), Jolly et al (2008) conducted evaluation of groundwater-surface water interactions in dry/semi-dry wetlands and the ramifications of salinity for wetland ecology [2]. Fleckenstein et al ( 2010) presented a study on groundwater-surface water interaction [3], the studied area in European Geosciences Union (EGU) General assembly was held in Vienna, and the researchers adopted numerical models to discover hypotheses and to improve new concept of models of GW-SW interactions.…”
