This document lists and briefly describes several pieces of software used in hydrology, including for groundwater modeling, hydrologic simulation, channel measurement, river assessment, chemical mixture analysis, stormwater management, watershed modeling, and creating specialized graphs for groundwater studies. It also poses two questions about lag times between runoff and baseflow peaks and what might cause a stream's discharge rating curve to change.

2. * Hydrology software for groundwater
modeling and hydrologic simulation.
 WaterCAD
 WaterCAD is an easy-
to-use hydraulic
modeling application
for the analysis, design,
and operation of
water distribution
systems

3.  RIVERMorph
The RIVERMorph® software is a
database oriented software
system geared towards channel
measurement data
collection/storage, reference
reach data collection/storage,
river assessment/monitoring and
engineering applications
including natural channel design

4.  Chemical Mixtures
Software (Linux/Win)
Version 1.0,
2013/07/01
The chemical mixtures
software is a collection
of computer programs
for investigating the
composition,
occurrence, distribution,
and potential toxicity of
chemical mixtures

5.  MIDUSS
MIDUSS offers a
complete solution for
stormwater
management,
design, and analysis.
Since 1984 MIDUSS
has been a
completely
interactive program.

6. WMS 8.4
The Watershed Modeling
System (WMS) is a
comprehensive graphical
modeling environment for
all phases of watershed
hydrology and hydraulics.
WMS includes powerful
tools to automate
modeling processes such
as automated basin
delineation, geometric
parameter calculations,
GIS overlay computations

7.  GW_Chart (Windows) Version 1.29.0.0, 2015/11/29
GW_Chart: a program for creating specialized
graphs used in groundwater studies.
 Feq (DOS/Sun) Version 4.1
Interactive Hydrologic Analyses and Data
Management
 PULSE (Win), 2007/01/29
Model-Estimated Groundwater Recharge and
Hydrograph of Groundwater Discharge to a
Stream
 NSS (Win) Version 6.1, 2015/05/06
National Streamflow Statistics program
 NFF (Win) Version 3.2, 2003/04/30
National Flood Frequency program

8. The lag time between the run off peak and
the base flow peak are different why?

9. What might cause the stream discharge
rating curve for a specific stream to
change?
