Attached is a status report on the WHFS site-specific model.
Keep in mind that this model is not intended to produce forecast
hydrographs with the accuracy or completeness of NWSRFS. It is intended
as a local, PRELIMINARY, assessment for significant site-specific
events while keeping support and use costs at an acceptable level.
It definitely performs better than the headwater table
approach and if it will provide at least similar results as other
site-specific models used around the country, it is a step in the
right direction. We realize that not all RFC's provide site-specific
guidance to their WFO's and that not all WFO's have a site-specific
A word about the rainfall-runoff equations used in this model.
They are based on the MBRFC API model, These were selected because
our headwater tables are defined using those equations and should
be adequate for purposes of this model version. As more performance
data is collected, other rainfall-runoff relationships can easily
I am considering a conference call among the RFC's in 2 weeks
or so to discuss the concept if you think that would be helpful.
In the mean time, feel free to contact me with comments and questions.
PLEASE remember, this is a beginning, not full-blown site-specific
model. We need to provide an initial WHFS model and get some feedback
before we know what improvements are required. Thank you.
