ABSTRACT:

Welcome to the age of the Water Data Deluge – certainly the most amazing period in human history to be a water resources scientist or environmental engineer! It is a peculiar and amazing time characterized by the creation, on a daily basis, of massive quantities of data and information that dwarf the world’s complete water data catalog of only a decade or two earlier. It is a time when an individual scientist with the most basic and inexpensive hardware and software can build a data collection network that can generate a veritable flood of information about the environment. So, what do we do with all of this data? How do we store, retrieve, visualize, document, cite, and make sense of environmental observations that quickly grow from the hundreds of thousands of values to the millions of values? What do we do when these counts escalate into to the billions or trillions of observations? Certainly a new generation of cyberinfrastructure is needed to help manage and interpret such data. In the United States, the National Science Foundation has funded a series of projects and programs centered on improved scientific cyberinfrastructure with the goal of creating a large ecosystem of tools and technologies that can help address these problems. This presentation will examine two such projects presently underway at Brigham Young University, including HydroShare: a system for community collaboration and data sharing in the cloud; and Tethys Platform: open source tools for rapid development and deployment of water and environmental web apps.

ABSTRACT:

Environmental Modelling & Software (EMS) is a highly ranked (IF: 4.177) Elsevier scientific journal that publishes contributions, in the form of research articles, reviews and short communications, on recent advances in environmental modelling and/or software. The aim is to improve our capacity to represent, understand, predict or manage the behavior of environmental systems at all practical scales. The topical scope of EMS is intentionally broad, which has the effect of attracting many hundreds of submissions per year. However, a large portion of these submissions do not fit within the journal scope in terms of the type and quality of contribution. Indeed, EMS has become noted as one of the top “methods” journals in the environmental science field. As such the editorial board is seeking submissions that provide strong methodological advances in both modelling and software. In this presentation, Editor-in-Chief Dr. Dan Ames will discuss the scope of the journal and will share the 5 most common reasons why research articles are rejected from EMS. Many of these concepts are applicable to other scientific journals and can be used to help authors improve their publication success rate in generally – as well as in EMS specifically. This presentation was delivered in Nanjing, China on September 20, 2018.

ABSTRACT:

In view of the ubiquitous mobile-app concept that has taken hold over the past decade, whereby distinct, single purpose, modular applications are developed and deployed in a shared user interface (i.e. the phone in your pocket), we have created open source cyberinfrastructure that mimics this paradigm for developing and deploying environmental web applications using open source tools and cloud computing services. This cyberinfrastructure integrates HydroShare for cloud-based data storage and app cataloging, together with Tethys Platform for Python/Django based app development. HydroShare is an open source web-based data management system for climate and water data that is includes a web-services application programmer interface (API) to allow third party programmers to access and use its data resources. We have created a metadata management structure within HydroShare for cataloging, discovering, and sharing web apps. Tethys Platform is an open source software package based on the Django framework, Python programming language, Geoserver, PostgreSQL, OpenLayers and other open source technologies. The Tethys software development kit allows users to create web apps that are presented in a common portal for visualizing, analyzing and modelling environmental data. We will introduce this new cyberinfrastructure through a combination of architecture design and demonstration, and will provide attendees the essential concepts for building their own web apps using these tools.

ABSTRACT:

From the dawn of the internet, water resources data scientists and engineers have continually and boldly engaged with the challenge of developing and deploying interactive water data visualization and analysis web sites. This challenge is characterized by ever-changing internet technologies, new and endlessly varying programming languages and libraries, rapidly growing datasets, and increasingly complex analytical and modeling techniques. Indeed, the ideal water web site is always just out of reach because of these always changing tools and growing needs. It is likely that such challenges will exist for many future generations of hydroinformaticists. However, we reason that it ought to be possible to at least reduce the gap between what we can readily accomplish with existing tools and technologies and what our ideal might be. Towards this end, the Tethys Platform for water resources web apps has been developed. This platform combines a number of key visualization and data management technologies within a Django-based Python programming environment that simplifies deploying GIS-enabled water resources web apps. The system provides developers and users with an app portal, not entirely unlike the app paradigm that is common on tablets and mobile phones, where each app is developed, tested, deployed, and operated independently of other apps in the same portal. The app development framework includes OpenLayers map visualization, 52North geoprocessing capabilities, PostgreSQL database access, and a number of so-called "gizmos" that simplify user interface development. This presentation will give an architectural overview of the free and open source Tethys Platform and will illustrate the capabilities of the framework using several apps developed using the recently released Tethys version 2.0.

EPANET_2.0
Created: Jan. 31, 2018, 4:05 p.m.
Authors: Lewis A. Rossman ·

ABSTRACT:

EPANET is a computer program that performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks. A network consists of pipes, nodes (pipe junctions), pumps, valves and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species throughout the network during a simulation period comprised of multiple time steps. In addition to chemical species, water age and source tracing can also be simulated.

EPANET is designed to be a research tool for improving our understanding of the movement and fate of drinking water constituents within distribution systems. It can be used for many different kinds of applications in distribution systems analysis. Sampling program design, hydraulic model calibration, chlorine residual analysis, and consumer exposure assessment are some examples. EPANET can help assess alternative management strategies for improving water quality throughout a system.
