摘要：In the Brantas River System, Sengguruh is the first reservoir in the direction of the river flow. This reservoir functions to protect Sutami Reservoir from severe sedimentation. The effective storage capacity was about 24% of its initial storage. In order to restore the storage, dredging work at Sengguruh Reservoir must be carried out over the course of the year. To support the dredging, it is necessary to carry out technical work so that sediments in the temporary spoilbanks can be immediately hauled to another place and then are ready to be refilled. Hauling can be done optimally if the sediment condition in the spoilbanks is quite dry. Therefore, it is necessary to know how horizontal drainage can affect the sediment water content in the spoilbanks.
