PC IHACRES (Identification of unit Hydrographs And Component flows from Rainfall, Evaporation and Streamflow data) PC-IHACRES uses a transfer function / unit hydrograph ( UH) approach to catchment-scale (lumped) rainfall-runoff modelling, developed jointly by the Institute of Hydrology (now CEH) and the Centre for Resource and Environmental Studies at the Australian National University. PC-IHACRES applications include investigations in small catchments instrumented for special studies, regional studies using readily-available data for large catchments, and quality assurance of strategically-important streamflow and rainfall records. PCSWMM 2000 This program is a decision support system for the US EPA's Stormwater Management Model (SWMM4). It utilizes the SWMM4 core processes and also provides a Geographic Information System ( GIS) with optional links to existing GIS/AM/FM/CAD databases.

The comprehensive PCSWMM 2000 can be used for solving problems ranging from small BMP installations to continuous hydrology, hydraulics and quality simulation of major/minor drainage systems. PLOTHYD version 1.3 for Windows With PLOTHYD the user can create and/or modify up to six hydrograph files at a time and produce consistent prints and plots of their data. The program provides statistics on the data to reduce error or evaluate data.
Rational Method Hydrology Small Area Rainfall Run Off Programs. Interactive user input file for easy file entry.
Built in hydraulics for subsequent design of structures. SCSHYDRO This program is a rainfall-runoff model based on U.S. Department of Agriculture Soil Conservation Service ( SCS) hydrologic procedures.
A modern replacement for TR-20. SMADA for Windows SMADA is a hydrology package which consists of a number of separate executable files. These programs work together to allow hydrograph generation, pond routing, storm sewer design, statistical distribution and regression analysis, pollutant loading modelling, matrix calculation and others.
STATS This program can be used to reduce large volumes of time series data to a few meaningful statistics or curves. The program will perform the following analyses: Duration curves, annual maximum events, annual minimum events, departures of monthly and annual values from respective means and annual volume duration exchange of high and low events. Streamflow Toolkit 2.0 This program gives users the ability to obtain various graphical presentations and statistical summaries of stream flow and water conditions at any gauging sites across Canada. Romans 3:23. STORMS 2000 With STORMS 2000 the user can create design storms (Chicago, SCS, AES, Huff, or User defined), create a database of IDF curves, generate IDF curves using the GEV distribution, determine the return period of observed events, and plot storm data or IDF curves on report ready charts. The program includes a database of more than 1200 Canadian meteorological stations.
SWMHYMO version 4.02 SWMHYMO can use single rainfall events (observed or synthetic) or continuous rainfall records to simulate the transformation of rainfall into surface runoff. Computed hydrographs can be routed through pipes, channels or stormwater control ponds and reservoirs. In urban areas, the effective capture rates of catchbasins and the effects of surface storage in street low points can also simulated. TOC TOC computes overland time of concentration using a combination of the Kinematic Wave Formula and the Green & Ampt method. The technique was developed and published by Dr. TR-55, Urban Hydrology for Small Watersheds version 2.0 This US SCS (U.S. Soil Conservation Service now the Natural Resources Conservation Service ( NRCS)) computer program was developed to calculate storm runoff volume, peak rate of discharge, hydrographs and storage volumes required for floodwater reservoirs.
The procedures are applicable in small watersheds, especially urbanizing watersheds in the United States. Unit Hydrograph Method Large Area Rainfall Run Off Software. Rainfall isohyetal data and the soil, development types (pervious ratio) are automatically area averaged for soil antecedent moisture conditions- required for most counties. Flood Hydrograph and Volume Calculations output. Export to ROUTE program for HEC-1.
Visual OTTHYMO version 2.0 Visual OTTHYMO version 2.0 (VO2) is a single event hydrologic model used to simulate hydrographs by modelling rainfall, infiltration, runoff and routing through a watershed. The hydrographs generated are based on unit hydrograph theory and can be used for uncalibrated or calibrated modelling studies.
The model is an appropriate design tool for use in projects such as watershed studies and stormwater management design. WMS (Watershed Modeling System) WMS is a comprehensive environment for hydrologic analysis. It is developed by the Environmental Modeling Research Laboratory of Brigham Young University in cooperation with the U.S. Army Corps of Engineers Waterways Experiment Station (USACE-WES). WMS merges information obtained from terrain models and GIS with industry standard lumped parameter hydrologic analysis models such as HEC-1 and TR-20. Terrain models can obtain geometric attributes such as area, slope and runoff distances.
Many display options are provided to aid in modeling and understanding the drainage characteristics of terrain surfaces.
