SCOPE OF RESERVO I R SYSTE~' FORHUlA TIO~1

The systems vi ewpoi nt adopted herei n focuses on the phys i ca 1

representation of the system and the system performance, in partic-

ular hydrologic and economic performance. For the present discus-

sion the social, political, institutional and environJ:1ental aspects

are assumed to act on the system (determining acceptable perfomance

criteria and alternatives) rather than comprising integral parts of

the analysis.

The physical representation of alternative systems is deter-
mined by the potentially useful reservoir sites, and locations
(termed control points) for which the systems are operated. Potential
reservoir sites are determined by analysis of the physical configura-
tion of the topography, physical and geologic characteristics of
the landscape and their proximity to potential damage centers. For
purposes of system formulation, a reservoir site is therefore
characterized by a physical location (distance from points of
interest), site storage-elevation relationship and the construc-
tion, operation and maintenance costs necessary to create the reser-
voir for a range of flood control storages. The stream system com-
prises a second important ele~ent in the physical configuration of
systems. The stream system can be characterized by the "topology"
(where water flows from and to) and hydrologic routing criteria that
