title: HEC-HMS models of major rainfall induced floods in ungauged mountain basins of Colorado

description: This dataset includes the models used in the journal article entitled,
 "Parameter Estimation for Models of Major Rainfall Induced Floods in
 Ungauged Mountain Basins of Colorado," published in the Journal of
 Hydrology Regional Studies.  Hydrologic Engineering Center –
 Hydrologic Modeling System (HEC-HMS) models are included for the following
 river basins and major storms in the Front Range and San Juan Range of
 Colorado: North Fork of the Big Thompson river (1976 storm), Big Thompson
 River (2013 storm), South Boulder Creek (2013 storm), Bear Creek (2013
 storm), Cheyenne Creek (1997 and 2013 storms), Saguache Creek (1999
 storm), Vallecito Creek (1970 and 2006 storms), and Mineral Creek (2004
 and 2006 storms). In each case, the model produces streamflow hydrographs
 based on the provided precipitation hyetographs. For each case, calibrated
 and uncalibrated versions of the models are included. The models also
 include models that estimate the streamflow for design storms that were
 generated from the Regional Extreme Precipitation Study.
description: Each basin and associated historical storm has its own HEC-HMS
 project or folder.  All project folders have an arbitrary date in the name
 that is separated by an underscore “_” from the basin name. For basins
 where only one historical storm was modeled, the Regional Extreme
 Precipitation Study (REPS) design storms are included in the same HEC-HMS
 project as the historical storm. This organization applies to Bear Creek,
 Big Thompson River (BTR), North Fork Big Thompson River (NFBTR), and South
 Boulder Creek (SBC). Although Saguache Creek has only one historical
 storm, a separate HEC-HMS project was created for the design storms due to
 the initial project file sizes.  Basins where multiple historical storms
 were modeled include Cheyenne Creek, Mineral Creek, and Vallecito
 Creek. The HEC-HMS projects (folders) are as
 follows: 201910_Cheyenne1997:  Calibrated
 and uncalibrated basin models and results for the 1997 storm
 Bear_201909:  Calibrated and uncalibrated basin models and
 results for the 2013 storm and the design storms
 BTR2013_201909_CombinedSubs:  Calibrated and uncalibrated basin
 models and results for the 2013 storm and the design storms
 Cheyenne_201909:  Calibrated and uncalibrated basin models and
 results for the 2013 storm and the design storms
 MineralCreek_202012 (Version 4.8):  Calibrated and uncalibrated
 basin models and results for the 2006 storm and the design
 storms MineralCreek2004_202012:  Calibrated and
 uncalibrated basin models and results for the 2004 storm
 NFBTR_201909:  Calibrated and uncalibrated basin models and
 results for the 1976 storm and the design storms
 SaguacheCreek_202011 (Version 4.8):  Calibrated and uncalibrated
 basin models and results for the 1999 storm
 SaguacheCreek_DesignStorms (Version 4.8):  Calibrated and
 uncalibrated basin models and results for the design storms
 SBC_20191028:  Calibrated and uncalibrated basin models and
 results for the 2013 storm and the design storms
 Vallecito_202010:  Calibrated and uncalibrated basin models and
 results for 2006 storm and the design storms
 VallecitoCreek2004_202012:  Calibrated and uncalibrated basin
 models and results for the 2004 storm
 VallecitoCreek1970_202101:  Calibrated and uncalibrated basin
 models and results for the 1970 storm Each
 HEC-HMS project contains the calibrated and uncalibrated basin models as
 HEC-HMS basin models.  The historical and design storms are represented
 using HEC-HMS meteorological models. The precipitation gauge time series
 describes the sub-basin average precipitation for each historical or
 design storm and are used to construct the meteorological models. The
 observed discharge at the basin outlet is included as discharge time
 series.  Reach cross-sections and any reservoir relationships are stored
 as paired data. Separate control specifications are used for the
 historical storms and the design storms due to differences in the period
 of the simulation.  Simulation runs are available for each combination of
 basin model and meteorological model in the HEC-HMS project. 
description: The files should be opened using HEC-HMS, which is available from
 the US Army Corps of Engineers. The HEC-HMS projects are mostly in HEC-HMS
 Version 4.7 format, but a few have been updated for Version 4.8.  Although
 the models were built using the terrain processing in Version 4.7, the
 associated geographical information system layers have been removed to
 reduce the size of the HEC-HMS projects.  It is anticipated that all
 models can be run in Version 4.8 or later.
