Basic Water-Use Questions*
Where
does our water come from?
Where does it go?
What is the water used for?
Who is using it?
How much is used?
How
do these facts change over time?
* Grammar check deliberately ignored...

Conveyance
A conveyance is a link between two sites.
Conveyances are one way.

Slide 5
Conveyance-Based Data
Model
How should we represent water-use data and activities?
A Conveyance-based model can represent any water exchange activity
between two objects - and promotes network / pathway thinking
From A To B
Pairs of Sites are joined through unidirectional Conveyances for which
water Transfer Quantities are recorded
Site-Conveyance chains represent the Site-to-Site-to-Site transfers as a
network of interconnected sites of various types, tracking water from its
source to its final point of consumption or return
“Water-use” contains the infrastructure elements that interact directly with
the natural hydrologic system through withdrawals and returns, and also
includes the various treatment, distribution, user/application, collection,
consumption, loss, and gain entities.

Slide 6
NJWaTr Core Conveyance Model
Sites are paired to form unidirectional Conveyances for which Transfer volumes
are recorded. Sites have Locations and Owners, and some interact with water
Resources (surface- and ground-water)
Slide courtesy of Steve Tessler based on work by Steve Domber (NJGS)
Slide 7
The logical basis for our water-use data schema can
be thought of as a “link-node” system. (Tessler and others)

Conveyance-Based Data
Model
Simple Water Network
2 Sites, 1 Conveyance
A Site is any object that can
be the Source or Target of a
water Transfer.
A Conveyance defines the
Transfer direction and
anchors the Volume details.

A More Complex Water Network
14 Sites (5 Types, 3 Spatial Scales), 14 Conveyances (4 Types)
Any complex water network can be
represented by a collection of
Sites/Conveyances.
A ‘Site’ may also represent aggregate
objects, such as purveyor area or
‘county livestock’

Conveyance-Based Data
Model
** There are Two Main Classes of Sites **
Resource-Interactors – and then all the others
Resource-Interactors are those Sites that interact
with the hydrologic system and can be associated
with Water Resources (aquifers, rivers, lakes,
reservoirs). These are Withdrawal and Return Sites.
All Other ‘Sites’ are part of the controls and
infrastructure that manage the handling, treatment,
transfer, distribution, collection, uses, consumption,
and applications of water.
