o. Input data

(1) All data cards use the first two columns for identification.

(2) Most data cards are optional and can be omitted unless options
are desired (e.g., J3-J8, etc.).

(3) Input is coded into 8 column fields for all input except for
one optional flow data fonnat of 6 collJlln fields.

(4) A blank field is taken as a zero input.

(5) All cards used must be in correct order as shown on card
summary and control points must be in order of treatment in routing and
combining flows.

(6) Metric or English units can be used.

p. Output

(1) Input data card images and a rearranged labeled input summary are
provided unless suppressed. Tile following output will .be provided if requested:

(2) Flow data

(3) Results of system operation arranged in downstream sequence
for reservoirs and control points.

(4) Reservoir data by period.

(5) Reservoir releases and control point regulated flow by period.

(6) Summary of flooding in system for each flood.

(7) Summary of maximum and minimum values for all floods.

(8) Economic output.

(9) Summaries of expected annual damages for system, and of
reservoir and control point costs and system net benefits for flood control.

(10) Frequency curve printer plot.

(11) Hydrologic efficiencies based on mu1tiflood events.

(12) Computation of incremental local flows.

(13) Output error check.

(14) Printer plots forhydrographs at designated control points.
