RiverWare is a General River and Reservoir System Modeling Tool that Meets These Requirements:

  • Multiple Uses - operational scheduling, forecasting, planning

  • Multiple solution methodologies - simulation,

    rulebased simulation, optimization

  • Operating policy expressed as data –

    create, view, change policies; see effects of policy on operations


Riverware is a general reservoir and river system modeling tool that meets these requirements
RiverWare is a General Reservoir and River System Modeling Tool that Meets These Requirements:

  • Easy to use – create complex physical process and policy models without writing computer code; point and click interface;

    Analyze results of model runs through GUI

  • Automatic Data Management Interface – import/export data from any source quickly

  • Extensible – add new features easily, reproduce results of old models

  • Supported / Maintained – new releases, user support, training


Object-Oriented Modeling Approach Tool that Meets These Requirements

  • Objects on Workspace Represent Features of the River and Reservoir System

  • Objects contain their own data

  • Objects contain their own physical process models

  • Objects know only about themselves

    - when they get a new value

    - how to use their data to simulate


Objects on the palette and their methods
Objects on the Palette and Their Methods Tool that Meets These Requirements

  • ReservoirsStorage (mass balance, release, spill)

    Power Reservoirs Level (+ tailwater, power, energy, eis)

    Sloped ( + wedge storage)

    Pumped Storage (+ pump/generators)

  • Confluence - mass balance

  • Canal - bi-directional gravity flow

  • River Reach - routing, water quality

  • AggDiversion Site - demands, consumption, return flow, available water

  • Water User - demands, consumption, return flow

  • Diversion - pumped or gravity diversion structure

  • Groundwater Storage - gw interaction for return flows, seepage, conjunctive use

  • AggDistribution Canal - calculates diversion schedules, routes flows

  • Stream Gage - input for river gage data; propagates flow value u.s. and d.s.

  • Thermal Object - economics of thermal power system

  • Data Object - user-specified data


Three solution approaches
Three Solution Approaches Tool that Meets These Requirements

1. Simulation

models physical processes for a variety of input/output combinations

(upstream/downstream; forward/backward in time)

2. Rulebased Simulation

simulation driven by user-specified operating rules (policy) expressed through an interpreted language

3. Optimization

linear goal programming solution


Usbr applications of riverware
USBR Applications of RiverWare Tool that Meets These Requirements

  • Colorado River – CRSS, 24-month study (stakeholders)

  • Lower Colorado EIS

  • San Juan – daily operations, EIS with USGS, BIA

  • Yakima – planning model

  • Upper Rio Grande – URGWOM with COE, USGS

  • Pecos – EIS with NMISC

  • Gunnison – policy analysis for environmental issues with NPS

  • Truckee River – accounting and daily operations

  • Umatilla – with BIA


Areas of ongoing usbr funded r d
Areas of Ongoing USBR-funded R&D Tool that Meets These Requirements

  • Water Accounting/Water Rights modeling

  • Enhancement to Rulebased Simulation to facilitate developing policy sets

  • Continued new physical processes and basin features modeled

  • Post processing and data connections


The okavango basin
The Okavango Basin Tool that Meets These Requirements


Okavango delta in flood
Okavango Delta in Flood Tool that Meets These Requirements


Sharing water towards a transboundary consensus on the management of the okavango basin
Sharing Water: Towards a Transboundary Consensus on the Management of the Okavango Basin

  • Joint proposal by NHI and IUCN to develop and test a transparent decision-making model (WEAP) in the context of the Okavango Basin

  • Build regional capacity to manage complex transboundary river systems and apply conflict management tools

  • Develop a set of key parameters necessary to monitor ecological trends in the basin


Adaptive management
Adaptive Management Management of the Okavango Basin

  • Acting without knowing enough, and learning.

  • Important management tool

  • Acknowledges incomplete understanding  

  • Iterative process


Adaptive management the process
Adaptive Management: the Process Management of the Okavango Basin

  • Define measurable goals and objectives

  • Develop a conceptual model

  • Generate hypotheses  

  • Explicitly disclose assumptions and uncertainties

  • Develop numerical model(s)

  • Design management interventions

  • Implement interventionsMonitor, and analyze results

  • Adjust management interventions accordingly

  • Design new interventions  


Lessons learned
Lessons Learned Management of the Okavango Basin

  • ·       Desired end conditions need to be clearly defined

  • ·Monitoring needs to be tied to specific goals

  • ·Our ignorance of ecosystems is uneven

  • ·Pragmatism is fundamental

  • ·“Battle of the Models”

  • ·Institutional Issues


Restoring aquatic ecosystems delivering on the promise of adaptive management
Restoring Aquatic Ecosystems: Delivering on the Promise of Adaptive Management

  • Analyze successes and pitfalls associated with adaptive management

  • Provide focused attention to further adaptive management practices - Yolo By-Pass, San Joaquin Basin, the Guadalupe River, and the Russian River

  • Advance the ability of NHI to assist in implementing adaptive management approaches in aquatic restoration
