Developing a New HEC-1 Model
About the Tutorial
This tutorial includes important guides in the use of DDMSW such as accessing helpful documents from the Help menu, setting and updating project defaults, setting the paths for saving model input and output files, and how model data is created and established. Model development involves the establishment of the following datasets, which are entered manually: (a) rainfall; (b) soils; (c) land use; (d) sub-basins; (e) routing reaches; (f) diversions; (g) storage facilities, and (h) flow data. The procedure also includes the development of the model network that defines the relationship of the different hydrologic elements (sub-basins, routing reaches, diversions, storage facilities, and direct flow data) in the model. DDMSW builds the HEC-1 models for the six standard return periods hard-coded in the program (2-year, 5-year, 10-year, 25-year, 50-year, and 100-year) and generates the flow hydrographs and peak flows associated with those return periods.
Data Sets
Model development involves the establishment of the following data sets, which are entered manually:
- Diversions
- Flow Data
- Land Use

- Sub-Basins
Procedure
The procedure also includes the development of the model network that defines the relationship of the different hydrologic elements (including sub-basins, routing reaches, diversions, storage facilities, and direct flow data) in the model.

Developing a New HEC-1 Model Using GIS Shapefiles
About the Tutorial
This tutorial illustrates the development of a HEC-1 model using shapefile datasets from GIS. The datasets include rainfall, sub-basins, soils, land use, flow paths (L, Lca, or Tc), and routes. The procedure includes a guide in customizing the data fields for each dataset such as names, data types, and data lengths. DDMSW evaluates and compiles the model parameters from these shapefile datasets and create a HEC-1 model based on the model network created by the user. DDMSW creates six (6) models for six standard return intervals hardcoded in the program, namely, 2-year, 5-year 10-year, 25-year, 50-year and 100-year storm events.

Updating NSTPS Values for Channel Routing
About the Tutorial
This tutorial was developed to guide users in evaluating the NSTPS parameter (HEC-1 RS card's first field) for channel flow routing in HEC-1 using the Drainage Design Management System for Windows (DDMSW) program.
The input data file is an existing HEC-1 input file where normal-depth storage routing methodology is used. The implemented tool within the DDMSW program creates an updated HEC-1 input file that includes a refined set of NSTPS values updated from two successive model runs.

Importing HEC-1 Stand-Alone Input File
About the Tutorial
This tutorial outlines the approach for importing an existing HEC-1 model input file with the goal to use the reporting and graphing features of the Drainage Design Management System for Windows (DDMSW) program.
The HEC-1 model parameters in the resulting DDMSW project cannot be updated because the supporting land use, soils, sub-basin and network data sets are not included during the import. The resulting model can only be run for one storm event - the specific storm event that was defined in the original HEC-1 input file.
See Tutorial #23 (only for DDMSW 5.6.0) on “Import HEC-1 Model and Update Losses” for procedural guide on updating model loss parameters when supporting project datasets are available.

Customizing HEC-RAS Table for DDMSW
About the Tutorial
This tutorial outlines the procedure in customizing a HEC-RAS table identifying which hydraulic parameters are to be included in the table and the order they are created.
HEC-RAS can save the custom format defined by the user so that it serves as a template that can be accessed and used for future projects. The imported data can be used for river mechanics analysis that includes scour, sediment yield, riprap sizing, and launch-able riprap.

Developing a HEC-1 Model With Custom Storm Event
About the Tutorial
This tutorial outlines the method for creating a Project with Custom Storm Event.
The procedure for creating a Custom Storm Event project is the same as developing a HEC-1 project using the S-Graph. The only difference is that the rainfall uses a custom distribution and the rainfall event is not necessarily associated with any return period. The procedure allows the user to enter the Rainfall Distribution to use in the analysis as well as the total storm depth. The procedure applies only to the S-Graph and not to the Clark UH Method.
