Motivation

requires integration of information from multiple sources

is data and computationally intensive

requires collaboration and working as a team/community

Data

Analysis

Models

Advancing Hydrologic Understanding

Grand challenge (NRC 2001): Better hydrologic forecasting that quantifies effects and consequences of land surface change on hydrologic processes and conditions

Floods and

Droughts

Data intensive models to understand and examine consequences, impacts and effects of land surface

and climate changes

From Larry Band

HydroShare Goals To provide a cyberinfrastructure platform for hydrologic

research to solve problems of size and scope not otherwise solvable using desktop computing through Software as a service Data as a service Models as a service Visualization and analysis services

To enable more rapid advances in hydrologic understanding through collaborative data sharing, analysis and modeling

To address community cyberinfrastructure needs

At its heart, HydroShare is a system for sharing Resources and Collaborating

Files and sets of files structured to represent a hydrologic process, model, or element in the hydrologic environment

Standard data models enhance interoperability and support functionality hydro value added

Tools that act on resources to visualize, modify and create new resources Encode standard/best practices

Summary1. A new, web-based system for advancing model

and data sharing 2. Access multiple types of hydrologic data using

standards compliant data formats and interfaces

3. Flexible discovery functionality 4. Model sharing and execution5. Facilitate and ease access to use of high

performance computing6. Social media and collaboration functionality7. Links to other data and modeling systems
