Water Simulation Packages (WSP)

CHECK-RAS, Version 1.4, is a program designed to verify the validity of an assortment of parameters found in the HEC-RAS hydraulic modeling program. This program can only be installed on computers with Windows 98/NT/2000/XP operating systems.

CHECK-RAS is available at FEMA web site.

H2OMAP SWMM Designer offers a very sophisticated optimization capability representing a major step forward for collection system modeling. With this capability, you can rapidly formulate and assess various reliable and cost-effective improvement solutions, which previously required a tedious trial-and-error approach or were not practical to even attempt. H2OMAP SWMM Designer leverages the power of advanced Genetic Algorithms optimization technology to automatically select the most cost-effective solution to flooding and pollution management, using a combination of pipe slope and size, storage, pumping and new piping to eliminate unwanted sewer overflows and achieve targeted system performance requirements. Performance criteria include maximum allowable depth to diameter ratio, minimum and maximum pipe velocities, and maximum head loss for force mains.

H2OMAP SWMM Designer is the ultimate tool to help engineers produce the best possible design and improvement alternatives with minimum effort and maximum cost savings. Its capabilities will greatly assist wastewater utilities in planning and designing reliable systems and optimizing their capital improvement programs - leading to healthier communities, cleaner beaches, and fish and shellfish that are safer to eat.

ModTech enables you to model groundwater flow and contaminant transport within a real-world geographic environment. ModTech has plenty of math power under its hood and - to extend the automotive metaphor - the steering and gear-box are pure Win-32: flexible, intuitive, and comfortable to the touch. This seamlessly integrated modeling & GIS environment enables you to:

• Design the model grid graphically or analytically
• Assign properties and introduce boundary conditions using a variety of methods
• Transform geographical objects or entire maps to model grids
• Visualize input parameters in 2D or 3D
• Run groundwater flow and contaminant transport simulations using common or proprietary solvers
• Automatically receive data for model calibration
• Display and interpret the modeling results in 2D and 3D
• Transform the modeling results to geographic objects
• Exchange input and output data with common GIS, CAD, and graphic formats

EPA’s Interactive Sampling Guide for Drinking Water Operators. Web conference. For Drinking Water Operators and others interested in learning about sample collection.

How many times have you pondered the question: “How do I collect that sample?” This webcast is for all new and veteran water system, technical assistance, and regulatory staff interested in learning about EPA’s interactive sampling guide for drinking water operators. The CD has four components:
1. Sampling Guide- In both video and powerpoint formats
2. Rule Wizard- a web-based program that allows the user to input
basic system information to generate the Federal sampling requirements
3. Case studies- Several case studies highlighting how other small
systems with detected contaminants dealt with their particular situation.
4. National Contaminant List- Easy download or view of the National
Contaminant List

ATS-Chester developed an interface to link EPA’s EPANET software with ESRI’s ArcGIS® software (it seems that it is an old version).

Applications:

• Water system modeling
• Water quality management
• Facility planning
• GIS integration
• User-friendly modeling

Features:

• Developed using ESRI’s latest ArcObjects technology.
• Adds a new toolbar to ArcGIS standard interface.
• Allows you to create and edit your EPANET model from inside GIS.
• Provides a synchronization tool to update existing models from GIS updates.
• Exports GIS layers as a backdrop for EPANET model.
• Allows displaying output results as a thematic map.
• ArcView 3.x version (AVNet also available).

MWH Soft released InfoWater UDF, a solution for unidirectional flushing of drinking water distribution systems. InfoWater UDF delivers helps in managing the systematic flushing of water distribution systems to remove stagnant water along with mineral and sediment deposits that accumulate over time - restoring hydraulic capacity and improving water quality.

The hydraulic carrying capacity of pipes deteriorates with age, proportionate to the corrosive nature of the water and surrounding soils. Precipitation, microbiological activity and corrosion may all form deposits on the pipe walls. These accumulations increase hydraulic roughness and reduce the cross-sectional area and hydraulic carrying capacity of the mains. A loss in carrying capacity can lead to low pressures and the inability to deliver fire flows, especially during high demand periods. Slow-moving water can also result in a loss of chlorine residuals at stagnant spots, creating a public health risk. Problems associated with water quality degradation are particularly acute in dead-end lines and low-demand portions of water distribution systems.
