CHARACTERISTICS OF INUNDATION FLOW AND FORESEEN DAMAGE IN MOUNTAINOUS FLOOD PLAINS CAUSED BY FLOODS DUE TO PROBABLE MAXIMUM PRECIPITATION

Comparison 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...

Reducing Inconsistencies in Point Observations of Maximum Flood Inundation Level

Flood simulation models and hazard maps are only as good as the underlying data against which they are calibrated and tested. However, extreme flood events are by definition rare, so the observational data of flood inundation extent are limited in both quality and quantity. The relative importance of these observational uncertainties has increased now that computing power and accurate lidar sca...

Using 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...

A 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 ...
