Accumulation of sediment materials in reservoirs of dams is one of the great problems for all dams. The Voshmgir dam has encountered the problem since the beginning of the water collection. So that, now, after three decades after the start of its operation, agreat part of its useful storage has been demolished. The vita] and important issues of the country like watershed management, environment and the matters related to water resources development, make the removal of storage dam sediment a very important subject. Investigation of the origin, amount, place, removal and agricultural and industrial uses of the reservoir sediments of Voshmgir dam and the construction materials made from the sediments arc carried out by the results of the activities and research works in the area of recognition of mineralogical, physical and chemical characteristics of the sediment. By removal of the dam resevoir sediments, the useful storage volume of the dam increases, the volume of sediments decreases and the raw materials for production of the artificial materials like brick,tile and ceramic are provided. Probable use of sediments as raw materials for construction of artificial materials through mineralogical, physical and chemical tests on the sediments of Voshmgir dam are investigated. In physical tests, the density of particles, particle size distribution and Atterberg limits were determined. In chemical test by analyzing the samples, the percentage of carbonate, sodium chloride, organic materials and loss of ignition of samples were evaluated. Finally, adobe samples which were made by traditional and pressure methods, were under the compression, bending and water uptake tests. The results were compared with Iranian 1162, German DIN 1230 and 51070 standards. The uses of these sediments tar construction ofʹartificial raw materials have been confirmed.
