National Regional Sediment Management Workshop13-15 July, 2004 – Honolulu, Hawaii System-Wide Water Resources Research Jack Davis, ERDC Steve Ashby, ERDC
Overview • Describe Proposed GI R&D Structure for Systems • Emphasize Upland to Coastal Connections • Solicit Field Input for RSM/Ecological Demos • Solicit Field Input on R&D Needs • Data Collection, Information Management • Geospatial, Remote Sensing, Mapping/Survey • Others?
General Problem • The Nation’s water resources are impacted by watershed, coastal, and CE activities • Technologies for system-wide assessments for sustainable management are not readily available
Current GI R&D Program Flood and Coastal Navigation Environment Project oriented Discipline oriented Disconnected

Sub basin loadings determined Capability being built into HEC-RAS. Reaches defined hydraulically Sediment Impact Assessment Model Goal: Balance sediment system when sub-basin loadings change (e.g. due to grade control, bank stabilization) & predict resulting instabilities/stability in downstream channel reaches.

Linked Models for Watershed Management View of projected urban growth around Fort Benning showing increase (yellow and orange) in on-post areas where activities may generate noise complaints. Proposed for Atlanta (multi-county) – LEAM – HSPF – CE-QUAL-W2 Urban – Runoff – Lake Response
Modeling Approach • Graphical user interface (GUI) • Common visualization and data manulipation tools • Multiple computational models and modeling approaches supported • Empirically based, lumped parameter models • Physically-based, distributed spatial parameter models • Single event models • Continuous models • Integrates multiple data sources to automate model parameter definition • Integrates directly with GIS through ArcObject
