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

  • 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

  • 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

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

  • 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

  • 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

Okavango delta in flood

Okavango Delta in Flood

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

  • Acting without knowing enough, and learning.

  • Important management tool

  • Acknowledges incomplete understanding  

  • Iterative process

Adaptive management the process

Adaptive Management: the Process

  • 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

  • ·       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
