Comparison of Temporal Rainfall Distributions for Near Probable Maximum Precipitation Storm Events for Dam Design
The Natural Resources Conservation Service (NRCS) has assisted local sponsors with analysis, design and construction of approximately 26,000 of the 80,000 dams in the National Inventory of Dams. Many of these dams are reaching their design life and require rehabilitation. Rehabilitation efforts come at a time when NRCS is in the process of evaluating a potential change from a minimum 6-hour sto...
متن کاملestimating the probable maximum precipitation in the bakhtiari dam basin using the statistical and synoptical methods
the two main approaches for estimating pmp are the synoptic and statistical techniques that their results are often different and selection of the appropriate option is difficult. in the most previous researches the frequency factor in the statistical method has been considered equal to 15 which this is the ultimate limit of frequency factor and the corresponding pmp is became too large. in the...
متن کاملComparison of physical and statistical methods for estimating probable maximum precipitation in southwestern basins of Iran
The probable maximum precipitation (PMP) is the greatest depth of precipitation for a given duration that is physically possible over a given size storm area at a particular geographical location at a certain time of the year. In this study a physically based method was compared with a statistical procedure to calculate PMP in the southwest arid regions of Iran. In order to estimate PMP using a...
متن کاملUsing Probable Maximum Precipitation to Bound the Disaggregation of Rainfall
The Multiplicative Discrete Random Cascade (MDRC) class of model is used to temporally disaggregate rainfall volumes through multiplying the volumes by random weights, which is repeated through multiple disaggregation levels. The model development involves the identification of probability density functions from which to sample the weights. The parameters of the probability density functions ar...
متن کاملA probabilistic approach to the concept of Probable Maximum Precipitation
The concept of Probable Maximum Precipitation (PMP) is based on the assumptions that (a) there exists an upper physical limit of the precipitation depth over a given area at a particular geographical location at a certain time of year, and (b) that this limit can be estimated based on deterministic considerations. The most representative and widespread estimation method of PMP is the so-called ...
