Summary of DISDATA
NAME
disdata - Data entry for fluvial sediment discharge program
(SEDDISCH)
ABSTRACT
DISDATA allows for keyboard entry and modification of measured
discharge and bed-material particle size data and storage into a
direct-access file for input to the SEDDISCH program.
METHOD
DISDATA allows the user to create, add to, modify, or list a direct-
access file that is read by SEDDISCH.
HISTORY
Version 1.3 1998/01/16 - Original program as ported and code clean-
up for use on UNIX workstations.
DATA REQUIREMENTS
Data are input interactively in a conversational fashion. The
following data are prompted for by DISDATA to form the SEDDISCH data
set:
measurement location
top width
mean depth
mean velocity
water-surface slope
water temperature
particle size, in millimeters, at which the 35, 50, 65,
and 90 percent by weight is finer (enter zero if not
required).
Bed-material particle size data are entered depending on the value
of the option code selected at the start of the run. One option is
that no size distribution data are to be entered. Zero values are
given to the percent-in-class variables for the size fractions. The
other two options are to enter the size data as percent-finer values
or as percent-in-class values.
SYSTEM REQUIREMENTS
DISDATA is written in Fortran 77. Generally, the program is easily
installed on most computer systems. The code has been used on UNIX-
based computers and DOS-based 386 or greater computers having a math
coprocessor and 1 mb of memory.
