Marte AQVAMarte AQVA
Need GstarCAD Version: GstarCAD 2010 or higher
Marte is the comprehensive software package for modeling and design hydraulic networks. Developed and commercialized by DEK, it is a powerful and reliable tool for engineers specialized in design and management of hydraulic networks.
In the process of developing and maintaining a complex system, the modeling of the network is a key part: customers must be supplied in a secure, reliable and efficient way at any time. Any decisions regarding this process may have a strong impact on anybody is involved in the process itself.
In this scenario, Marte has become more and more important for many Italian companies as an efficient tool for the analysis and the design of distribution networks.
Based on AutoCAD and Microsoft Access, it delivers powerful data managing and plotting features and simplify integration with third-party solutions.
The advanced calculus features of Marte and the possibility to make accurate models of the network behaviour can be the value added and the successful key in the actual scenario of integrated hydraulic services.
Extended period simulation for water distribution networks
The Epanet code
Epanet is the Marte AQVA code for performing extended period simulation of hydraulic and water quality behaviour within pressurized pipe networks. Epanet is really useful for professionals involved in the management of water distribution networks. With Epanet you can investigate flow rates in pipes, pressures in pipe junctions and levels in each network tank at any time during the simulation.
Epanet is developed by US EPA Water Supply and Water Resources Division.
The Epanet code, besides performing an hydraulic analysis of the network, allows to simulate the quality behavior of network. It provides the following water quality modeling capabilities:
Water age: provides a simple, non-specific measure of the overall quality of delivered drinking water; modeling the changes in the age of water throughout a distribution system. The code treats age as a reactive constituent whose growth follows zero-order kinetics with a rate constant equal to 1, this mean that each second elapsed the water is 1 second older. New water from reservoirs, tank or source junction enters the network with an age of zero.
Source tracing: source tracing tracks over time what percent of water reaching any junction in the network had its origin at a particular junction. The source junction can be any junction in the network, including tanks or reservoirs. Internally, the code treats this junction as a constant source of a non-reacting constituent that enters the network with a concentration of 100. Source tracing is an useful tool for analyzing distribution systems drawing water from two or more different raw water supplies. It can show to what degree water from a given source blends with that from other sources, and how the spatial pattern of this blending changes over time.
Growth or decay of a substance: track the growth or decay of a substance by reaction as it travels through a distribution system. Reactions can occur both within the bulk flow and with material along the pipe wall.
