What's new in Hicalc
V1.4 ?
HiCalc is now available in two
versions

HiCalc Light (all functions
included in previous releases) HiCalc Full (new features,
such as export data, detailed analysis of gradually varied
flow, etc.)
HiCalc 1.4 will recognize
registered users of previous versions and will work in "Light"
mode. To upgrade to HiCalc Full you can buy a registration
code at http://www.istec.com.uy/hicalc .
This version represents a major
change in the software and includes the following new
features:

Incorporates Windows type help,
containing definitions, a brief HiCalc's manual as well as
some advice in the use of HiCalc.

HiCalc's design is changed to
multiple forms interface, which allows to work
simultaneously in different forms and to visualize the one
that the user wishes.

Data processing. Reducing to a
minimum the possibility of abrupt closings by erroneous data
entered.
New features in HiCalc
+ For the case of Gradually
Variable Flow (GVF) the results include all the hydraulic data
in the intermediate points including alternate and conjugated
depths (HiCalc Full only). + These data can be exported to
a text file delimited by ";" that it can easily be exportable
to spreadsheets software (HiCalc Full only). + Is possible
to plot (screen and printer) the behavior in the channel of
anyone of the hydraulic parameters (HiCalc Full only) +
Incorporates the calculation of conjugated depths from the
momentum.
What's new in details of
algorithms and the modelling
+ The algorithms are much more
efficient and stable. + Controls the input data to model
GVF, must move away of zero, the maximum depth, critical and
normal depth at least one equal distance to the permissible
error + Controls exhaustion of curves to arrive at
some from the extreme depths with warning for the
user
Frequently asked questions:
What's and what for is applicable
this program?
Hicalc is a software package to
quickly solve open channel flows with rectangular, trapezoidal
or cylindrical section. Solves steady situations of Uniform
Flow (example: infinite channels) and/or Gradually Varied Flow
(example: backwater curves). It is not possible to be applied
for Space Varied Flow (example: lateral dumps) or Quickly
Varied Flow (However solves hydraulic jump and energy
transitions). This program was developed in Visual MS BASIC
6.0 and works under MS Windows 95 or superior. The
program that you can download is free to use and the copy
distribution is allowed. However, register code distribution
is forbidden. Comments and suggestions: mailto:webistec@movinet.com.uy
Why to register your copy
of Hicalc?
When you register your copy, you
will receive a user name and password that allow you to run
HiCalc in Full mode. You will be able to solve trapezoidal and
circular channels, export data, get detailed analisys of
gradually varied flow, plot and print the behaviour of the
most important hydraulics parameters.

Example
1
Calculate the depth (flow height)
of water that circulates around wide a rectangular channel of
5 m of width and slope angle of 1V: 2H, when the flow is 20
m^3. The flow is subcritical or supercritical? The slope of
the channel is 3 by thousands and de roughness Manning’s
coefficient is 0.022
Answer:

First that is due to do it is
to define the geometry of the channel. Introducing "2" in
"Side Slope Angle" and selecting convert, we observed that
the angle of the slope corresponding to a slope 1V:2H
corresponds to 26 degrees 56min. In addition, to add "5" in
"Base Width".

Then, we introduce the data of
slope (0.003), Roughness Manning’s coefficient (0.022) and
Flow (20) and click on "Calculate" at "Uniform Flow
Depths".

We obtain that the critical
depth is 1.02 and the normal depth is 1.20. Therefore, in
conditions of regime it uniforms the depth is of 1.202. As
the normal depth is major who the critical depth, then the
flow is supercritical.

If it is desired to obtain
other parameters corresponding to the channel of the problem
and with the corresponding depth (by example: 1.202 ms), we
go to "Hydraulic Parameters", wrote "1,202" and we selected
to calculate! And one obtains the most important parameters:
Tension, Area, Wet Perimeter, etc.
