A new release of the DC Water Design Extension is available from:

http://dcwaterdesign.sourceforge.net

The DC Water Design Extension is a free ArcView 3.x extension that integrates EPANET with ArcView.

The changes:

* Bug fixes especially to the start menu links

* Three new functions: Split Model, Merge Model, Extract Model





InfoSWMM Version 4.0

Friday 26 August 2005 @ 10:58 am

MWH Soft Ships InfoSWMM Version 4.0 for Comprehensive Urban Drainage Modeling. The company announced the worldwide availability of the V4 Generation of InfoSWMM for ArcGIS (ESRI, Redlands, CA).

As a full-featured urban drainage network analysis and design program, InfoSWMM delivers the highest rate of return in the industry. All operations of a typical sewer system - from analysis and design to management functions such as water quality assessment, pollution prediction, urban flooding, real-time control and record keeping - are addressed in a single, fully integrated geoengineering environment. The program offers users unprecedented power in managing urban runoff and wet weather water quality problems in combined, sanitary and storm sewers; optimizing BMP and LID designs; and meeting SSO and CSO regulations. The model also offers highly sophisticated Real-Time Control (RTC) schemes for the operational management of wastewater systems and hydraulic structures. The unparalleled performance modeling of InfoSWMM sets new benchmarks in scalability, reliability, functionality and flexibility within the powerful ArcGIS environment.

HAMMER Version 2

Sunday 7 August 2005 @ 12:15 pm

HAMMER is a free program I used a few years ago to simulate water hammer in a water pipe.

From HAMMER read me file:

HAMMER is a program which simulates the effects of water hammer in a reservoir and pipeline system in which a valve at the downstream end is opened or closed by the user. The program is a product of the Urban Water Systems Group, School of Civil Engineering, Queensland University of Technology.

The program solves the differential equations of transient flow in a simple pipeline with a reservoir at the upstream end and a valve at the downstream end. The aim of the program is to provide a demonstration of the effects of water hammer in a simple pipe, reservoir and valve system. The method of characteristics is used in the solution of the differential equations.

Darwin Designer team won honorable mention for the “Humies” Award

Monday 1 August 2005 @ 8:22 am

The Human-Competitive Awards, the “Humies”, are awarded to techniques of genetic and evolutionary computation that are competitive with the work of creative and inventive humans.

The Darwin Designer team, from Haestad Methods, won an honorable mention this year for their water distribution design genetic algorithm solver. The method is presented in “OPTIMIZING WATER SYSTEM IMPROVEMENT FOR A GROWING COMMUNITY”

Abstract:

To meet the water supply requirement in a growing community, system improvement alternatives needs to be identified to satisfy the increasing demand. This paper shows that the intelligent optimization modeling tool can assist practical engineers and decision-maker to optimize system expansions and prioritize the budget allocation of capital improvement program (CIP) for a real world water system. The water distribution system undertaken for study represents a community where the water consumption is projected to grow 30% in 15 years. Increasing consumption requires that the water system be improved to move water from sources into the growing areas. The criteria for enhancing the system capacity include satisfying the pressure requirement, the maximum allowable flow velocity and sufficient tank storage. The improvement task is to identify the feasible pipe routes and pipe sizes of the new pipes. Due to the complex interconnectivity and the large combinations of possible pipe routes/sizes, it proved technically impossible for experienced engineers to identify a feasible design solution. GA-based optimization design tool has been applied to forge the cost-effective system improvement solutions. The study shows that optimization modeling is a powerful approach for supporting and enhancing a sound decision-making process in water industry.
