Compendium on methods and tools to evaluate impacts of, and vulnerability and adaptation to, climate change
CALVIN (CALifornia Value Integrated Network)

Description
|
This is an economic-engineering optimization model of California’s inter-tied water supply system,
based on the US Army Corps of Engineers HEC-PRM software. Data on surface and ground water hydrology,
infrastructure connectivity and capacities, operating costs, economic values for water deliveries, and
environmental flow constraints are combined with an optimization solver to identify promising integrated
water management strategies coving surface water ground water, water conservation, water market, water reuse,
and desalination water management options.
|
|
Appropriate Use
|
This is a screening model for planning and policy purposes.
|
|
Scope
|
Models for US California, its sub-regions, and Baja California, Mexico.
|
|
Key Output
|
Costs, marginal economic values, and monthly water management decisions are provided for the time series of
hydrologic data provided.
|
|
Key Input
|
Surface and ground water inflows (time series), system connectivities and infrastructure capacities,
operating costs, economic values for water deliveries, water loss coefficients, evaporation rates.
|
|
Ease of Use
|
Not easy
|
|
Training Required
|
3-4 day course, plus prior modeling experience and familiarity with water management systems.
|
|
Training Available
|
Short courses are available from UC Davis, UABC-Ensenada, and several California consultants.

|
|
Applications
|
Statewide and regional water models of US California and Baja California, Mexico. Applications include:
valuing infrastructure expansions, water markets and transfers, conjunctive use, integrated resource
management, climate warming adaptation, adaptation to a repeat of a severe and sustained paleodrought, Hetch
Hetchy dam removal, Colorado River restoration, etc.
