ABSTRACT:

Studies of water and environmental systems are becoming increasingly complex and require integration of knowledge across multiple domains. At the same time, technological advances have enabled the collection of massive quantities of data for studying earth system changes. Fully leveraging these datasets and software tools requires fundamentally new approaches in the way researchers store, access and process data. The project serves the national interest by motivating a culture shift within the hydrologic and more broadly earth science communities toward open and reproducible software practices that will enhance interdisciplinary collaboration and increase capacity for addressing complex science challenges around the availability, risks and use of water. Project's CyberTraining approach provides virtual learning experiences throughout an academic year, with online learning modules oriented around a one-week in-person workshop (WaterHackWeek) that will focus on hands-on real-world research projects. These research projects are designed to serve the national interest by preparing for natural hazards such as floods, hurricanes and climate change, and to advance the nation's health by making tools and data accessible to health researchers, local governments, and citizens.

New cyberinfrastructure that emphasizes data sharing and open, reproducible software practices is currently in development, but requires a mode of knowledge transfer, or CyberTraining, that extends beyond currently available university curriculum. Project's aim is to ensure successful use of community cyberinfrastructure to 1) publish large datasets, 2) run numerical models, 3) organize collaborative research projects, and 4) meet journal requirements to follow open data standards. The activities take advantage of HydroShare, a National Science Foundation funded cyberinfrastructure platform, operated by the Consortium of Universities Allied for Hydrologic Sciences (CUAHSI), for sharing hydrologic data and models. The short-term goals are to develop new CyberTraining modules; the long-term goals are to have an annually recurring WaterHackWeek, to distribute curriculum CUAHSI to more than 130 member universities, and advance cyberinfrastructure education for the broader geoscience community. The use of the hackweek educational model extends the use of cyberinfrastructure to promote the progress of science by including a specific emphasis on graduate student training as instructors, training coordinators, and building research networks with data providers who are stakeholders outside of academia. For example, case studies include data and resource management by Native American tribal governments, Hurricane Maria data archive for research in Puerto Rico, improving flood forecasting, and tool-building using complex numerical models such as the National Water Model. This project allows to test the educational model in the water research community, in addition to connecting team's research and curriculum to annually recurring hackweeks in neuro, astro, ocean, and geo sciences. The team of researchers is actively engaged in experimenting with this new model, and in testing its efficacy through robust evaluation metrics. The proposed activities encourage collaboration and support for use of cyberinfrastructure at all stages of the educational pipeline and provides participants with opportunities for networking, career development, community building and design of open-source software tools.

ABSTRACT:

This collection contains legacy documents archived from CUAHSI's website during the 2021-2022 website migration. These documents pertain to the founding and mission of CUAHSI. Upon creation this collection will contain nine PDF documents, and may be added to again in the future if the need arises.

ABSTRACT:

The document included in this resource outlines the initial requirements, design, and implementation of what would become HydroShare. The document is titled "A CUAHSI DataCenter for Hydroinformatics: Draft Specifications", and was written in 2012 by Alva Couch. The scope of the document is as follows:

This document is not a complete proposal, nor does it attempt to scientifically justify the above missions of the datacenter. Instead, this document focuses upon the feasibility of accomplishing the above missions, the technical details of doing so, the design of the overall personnel and computing infrastructure necessary to do so, and the cost of that infrastructure.
This document is separated into three logically distinct parts: requirements, design, and implementation.
• The requirements section lists the overall requirements for the datacenter, including mission, relationship to prior work, and perceived high-level challenges of meeting the mission.
• The design section specifies how the datacenter will meet requirements via high-level capabilities, processes, and personnel roles.
• The implementation section describes policy decisions to be made in implementing the design, including a plan for overall sustainability of the datacenter.

Current practices to identify, organize, analyze, and serve data to water resources systems models are typically model and dataset-specific. Data are stored in different formats, described with different vocabularies, and require manual, model-specific, and time-intensive manipulations to find, organize, compare, and then serve to models. This paper presents the Water Management Data Model (WaMDaM) implemented in a relational database. WaMDaM uses contextual metadata, controlled vocabularies, and supporting software tools to organize and store water management data from multiple sources and models and allow users to more easily interact with its database. Five use cases use thirteen datasets and models focused in the Bear River Watershed, United States to show how a user can identify, compare, and choose from multiple types of data, networks, and scenario elements then serve data to models. The database design is flexible and scalable to accommodate new datasets, models, and associated components, attributes, scenarios, and metadata.

The summary of the document is as follows:

Mathematical models are important tools to understand water in the continental Earth system, but none of the currently available models are adequately complete to tackle the diverse set of critical science questions facing society today. The large number of available models has limited collaborative development within the water sciences and limited interaction with sister disciplines, like the atmospheric and ocean sciences. This document outlines a plan to create a Community Water Model, which will be designed to provide the best available simulations of the hydrologic cycle and coupled water processes within the contiguous United States and adjacent watersheds. This will be accomplished by developing a modeling platform patterned after current multiphysics modeling software that has been optimized to solve problems related to water. The platform will provide the computational resources and access to data required to create a Community Water Model. The CWM will enable multiple workflow configurations to meet the wide range of objectives for which hydrologic models are constructed. It will be an open source code managed by the scientific community and it will grow in capabilities through contributions from the community. The Community Water Model can serve as the connection point for other disciplines that require prediction of continental water movement including general circulation, landform evolution, biogeochemical, vegetation, ecological and economic models.

The introduction of the paper is as follows:
The EarthCube goal of creating an infrastructure for managing and integrating knowledge across all
geosciences in an open, transparent and inclusive manner aligns well with the overarching goals for the
work that has been done in CUAHSI on Hydrologic Information Systems. CUAHSI has taken some steps
in this direction, but a lot remains to be done. This paper describes these steps and makes some
suggestions for the path ahead.

The purpose of this report is as follows:
Experience from the CUAHSI Hydrologic Information Systems project has shown that a multi-phase approach is needed to move from concept to a community facility. The conceptual phase must be followed up by a pilot phase to scope a project more precisely and to determine the best approach to delivering a service. The pilot phase is then followed by a developmental phase when the specific tools and services are “hardened” by testing them with a limited clientele to ensure reliability and operational readiness to serve the community. Only then have the necessary attributes of an operational community service been fully defined. This science plan summarizes the results of these interim community planning efforts.

The executive summary of the document is as follows:
The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) is continuing a major effort towards the development of a Community Hydrologic Modeling Platform (CHyMP)1
Over 30 participants attended the third workshop (see Table 1), and were invited based on their experience and expertise across a range of aspects of hydrologic modeling. Attendees from the U.S. and abroad represented universities, government labs and federal agencies. . A first, scoping workshop was held in March, 2008 [Famiglietti et al., 2008, 2009], and identified the need for a substantive, university-led community modeling activity in hydrologic science. A second workshop, Blueprint for a Community Hydrologic Modeling Platform (CHyMP) Workshop, further developed the community vision of CHyMP. This 3rd workshop, A Strategic and Implementation Plan, was held March 15 – 17, 2011 at the Beckman Center for the National Academies at the University of California at Irvine, to come to community consensus on how to move this vision forward. Sponsored by the National Science Foundation (NSF), the UC Center for Hydrologic Modeling and CUAHSI, the goal of this workshop was to identify concrete steps around several areas related to implementing a community hydrologic modeling effort.

ABSTRACT:

The purpose of this module is to give users the ability to perform simple, repeatable actions in Matlab online through its association with HydroShare, and demonstrate discovering and using data, and performing operations on data within the CUAHSI data ecosystem. To begin the module, download the instructions document.
This Module will also utilize the built in HydroShare library, which is used to communicate between CUAHSI’s Matlab online and HydroShare at the resource level.
In this module, learners will discover a resource in HydroShare that contains rainfall data and ready to use MATLAB code, and use MATLAB online to create a unit hydrograph. Students will then use MATLAB online to store the results of their analysis in the same Hydroshare resource, and go through the steps of sharing their results to a group.
