      abstract = {Accumulations of floating debris in reservoirs can have  negative impacts on the safe operation of a dam. Thus,  adequate spillway design in view of driftwood is of  paramount importance. Herein, investigation of driftwood  blockage with a reservoir flow approach was conducted. A  laboratory facility was used to evaluate blockage of  artificial stems at an ogee crested spillway equipped with  piers. With a systematic approach, the effect of blocked  stems on the head at a reservoir was qualitatively  investigated. Experiments with manually blocked stems were  performed to study the effect a blockage can have on the  reservoir head. Experiments releasing 200 stems were  performed to study jam shapes and their probability to  cause a head increase. It was found that similar blocked  volumes of stems had different effects on the head increase  in the reservoir and were dependent on whether stems were  in contact or not with the spillway crest. It was also  found that an increasing head tends to decrease the  blocking probability but not linearly.},
