Effective Communication of Your Computer Modeling Efforts - Hydrology and Hydraulics

This paper presents efforts by the Dam Safety Toolbox - Model Communication Study Group to develop guidance for communication of computer modeling efforts specific to hydrological and hydraulic modeling. Phase I of the project, and this paper, focus on information that should be determined and communicated in advance of analysis. Depending on the complexity of the project, the modeler should be prepared to discuss the following topics with the dam owner and regulator in advance of initiating a modeling effort:
•Detailed model purpose and justification.
•General assumptions and modeling approach (e.g., software selection, parameterestimation, data sources, etc.)
•Rainfall source, events modeled, infiltration loss estimation method, runoff convolutionmethod, channel routing method, sub-basin delineation criteria.
•Validation and/or calibration approach (e.g., historical events, previous modeling efforts,sensitivity analyses, etc.)
•Regional dataset comparison, reservoir response to historic floods, pool of record.
•Anticipated level of effort and schedule.
•Possible outcomes / expected outcomes.
