Modeling of the human brain is done at two levels, a macroscopic, inter-
neuronal level and a microscopic, intra-neuronal level. With the former, vari-
ous models have been proposed in the literature for artificial neural networks
(ANN) dealing with such specific brain functions as function approximation,
pattern recognition, classification and control. In modeling at a microscopic
level, energy transfer across the cells without dissipation is conjectured in bio-
logical matter. This idea has led to construct models for water reservoir opera-
tion, which can assist water resources system analyst in selecting compromise
strategies for water release from the reservoir. Multilayer Feed forward networks
such as Back-propagation with Levenberg-Marquardt Algorithm (BPLM) and
Recurrent Neural Network (RNN) model as inter and intra neuronal architec-
tures are formed. The aim is to find a near global solution to what is typically
a highly non-linear optimization problem like reservoir operation. The main
reason for this study is due to the research results

on back-propagation (BP)
technique and its performance. The case study used in this paper to demon-
strate the effect of these architecture geometry and various internal parameters
is that of deriving operational policy for the river Vaigai in south of Tamil Nadu
in India.
1. Introduction
Learning denotes changes in the system that are adaptive in the sense that
they enable the system to do the same task or tasks drawn from the same
population more effectively next time. The primary objective of the reser-
voir operation is to maintain operation conditions to achieve the purpose for
which it has been created with least interference to the other systems. In this
paper, integration of surface and groundwater available is made use of as
resource available for water meeting irrigation demand of the basin. Effects
of inter basin transfer of water between Periyar and Vaigai system is also
carefully studied in determining release policies. The inter-basin transfer
of water not having negative environmental impacts is a good concept but
that should also have social and cultural consideration, price considerations
and some environmental justice considerations. There are significant water-
sharing conflicts within agriculture itself, with the various agricultural areas
