VOlM and AREA Records

,

,

The AREA and VOLM records provide the volume and corresponding surface area
points for a reservoir. Th~ VOLM and AREA records together constitute a tabular
representation of a capacity-area curve for a specitic reservoir (identitied in the RESX record).
Each volume point must have a corresponding area point. These records are required for each
reservoir. Each non-zero point on the VOLM record must be unique to avoid divide-by-zero
errors in the surface area interpolation subroutine. The tirst field in the VOLM or AREA
record contains the type specitication ('VOLM' or 'AREA'), and the following tields. in order,
contain reservoir number and a maximum of ten reservoir volume or area values in increasing
order. For each value of volume, there is a corresponding value of area. Fields are separated
by one or more spaces.

DEMN Records

Demand arcs withdraw water from the network. The tirst tield of the DEMN record
contains the type specitication ('DEMN'), and the following tields, in order. contain demand
number, demand name. node number at which demand occurs and 12 seasonal demand ranks.

DEeR Records

The Decree arcs function like Links except that their capacities are stated as a
cumulative amount over 12 months. The tirst tield of the DECR record contains the type
specitication ('DECR'), and the following fields, in order, contain decree number. decree
name, from node, to node. number of retills, and i2 seasonal ranks.

(NFL Records

Intlow arcs force water into the network. They generally represent tlow of a stream
entering the system. The first field in the INFL record contains the type specitication
('INFL'), and the following tields, in order, contain intlow number, intlow name and node
number at which intlow occurs.

RTFl Records

Return tlow arcs force water into the network. Return tlows are represented by a set of
records: the RTFL, RTNSOURCE and RTNFRACTS records. These records are used to .
assign return tlow destinations and to disaggregate return tlows from each source in both time
and space. The tirst tield in the RTFL record contains the record type specification ('RTFL').
The following fields, in order, contain the return tlow number, the node number at which the
