The results show that using Latin Hypercube sampling, the uncertainty of accumulated reservoir sediment volume is 37% for total time periods and 31% for wet and dry periods, and in Harr's method the uncertainties are 38% and 23% respectively. The effect of each uncertain factor, both individually and in combination, on the uncertainty of accumulated reservoir sedimentation through time were examined for Shahar Chai Dam in Iran.

Sensitivity analysis was conducted to examine the importance of various factors on the uncertainty of accumulated reservoir sedimentation. The following table summarizes the names of -dimensional hypercubes. It is a regular polytope with mutually perpendicular sides, and is therefore an orthotope. It is a closed, compact, convex figure whose 1- skeleton consists of groups of opposite parallel line segments aligned in each of the spaces dimensions, perpendicular to each other and of the same length. Latin Hypercube sampling and Harr s probabilistic point estimation method were used to quantify the uncertainty of accumulated reservoir sedimentation through time. The hypercube is a generalization of a 3- cube to dimensions, also called an -cube or measure polytope. In geometry, a hypercube is an n -dimensional analogue of a square ( n 2) and a cube ( n 3 ). To evaluate suspended sediment and bed load for some hydrometric stations, in addition to using the total time period, the field data were separated into wet and dry periods. In estimating reservoir sedimentation and accumulation, a number of uncertainties arise, including the quantity of streamflow, sediment load, sediment particle size and specific weight, trap efficiency, and reservoir operation. One of the problems that affects hydroinstallations and reduces the useful life of dams is sedimentation in the reservoir.
