Review of Day 1

Modules

Watershed Setup, Network, Simulation

Configurations

selection of projects

Reservoir Networks

~90% of your model – all the details

Alternatives

combinations of a network and selected timestep, initial conditions, inflows, operation sets, 

Computation Points

where we want to share output with other models, points of interest

place them:

  • where you have gages
  • where you want to add local inflows
  • confluences
  • upstream and downstream ends of reaches & reservoirs

they become junctions in your network

Stream Alignment

river system

Lookback

initial conditions

  • can be a time series or constant
  • new options: guide curve, function of inflow/outflow

Note that ResSim typically does not calculate mass balance during lookback.  it just blindly follows the lookback settings you give it.

Zones 

  • division of reservoir into elevation-based subsections.  operations may vary from zone to zone.
  • zones are defined by the top of an elevation curve
  • bottom zone is inactive (also called dead pool).  there are no outlets available there
  • you could have an operational inactive zone where 
  • top of conservation is where ResSim 

Guide Curve

  • top of zone

8 Project Purposes

  • fish and wildlife
  • recreation
  • navigation
  • water supply
  • flood protection
  • hydropower
  • irrigation
  • water quality

Operational Goals

  • based on project purposes
  • power plants and other things have their own constraints 

Flood Control Objective

  • #1 objective = save the dam 
  • don't make downstream flooding worse
  • reduce damages
