Reviews of current methodologies for the determination of the worth of hydrologic data indicate that each method has certain shortcomings. The simulation approach requires information concerning the statistical properties of the data that are not usually known. The Bayesian Approach often leads to mathematically intractable relations. The two approaches may be combined by defiing the data worth through simulation under the condition of assumed statistical properties and releasing the conditioning by making use of the prior distributions of the unknown statistics obtained from the Bayesian approach. This combined approach circumvents the problems encountered when either the Bayesian or the simulation approach is used exclusively. An example illustrates the use of the combined approach in evaluation of the worth of flood data in the design of highway crossings.
