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
