Abstract: A Field investigation was studied the differential and unusual movements of the construction joints for Al-Shamiya barrage structure located in the south of Iraq. Based on the field observations, three cases considered to identify the causes of barrage problem; vibrations, sedimentation and river meandering phenomena. The systematic procedure was followed to analysis and obtain the collected data of all cases. Special vibration device (VIBRATION METER VT:8204) used to test and records the data in different locations of the barrage body. The limitations of the vibration values for Al-Shamiya barrage were recorded between (0.6-0.65) mm/s. The suspended sediment load was calculated in the upstream of Al-Shamiya barrage using the Acoustic Doppler Current Profile device. The data collected within the selected period are analysed and calculated the total load of about 2200 tons of sediment resting on the U/S barrage bays. The obtained results compared with the barrage design data (safety limitations) to suggest sound recommendations to solve such a problem.
