ABSTRACT
In this study, HYMOS 4.0 software has been used to synthesize monthly flow series for
thirteen years in each of the twelve tributary subcatchments of the Betwa basin up to Rajghat.
The HYMOS 4.0 software uses Sacramento model to synthesize discharge data. Monthly
rainfall data for 14 stations from 1980 to 1992; ten daily discharge data for 2 stations (Basoda
and Rajghat) from 1980 to 1992 and daily evaporation data for 1 station (Sagar) from 1980 to
1992 has been used as input in the Sacramento Model. The Coefficient of determination and
NashSutcliffe Efficiency between observed flow at the Basoda and sum of six tributaries
synthesized discharge were found to be 0.862 and 0.837respectively. Similarly, The
Coefficient of determination and NashSutcliffe Efficiency between observed flow at the
Rajghat and sum of twelve tributaries synthesized discharge were 0.841 and 0.839
respectively. The difference between observed and synthetic discharge of Bina basin varies
from 1.79% to 11.62%. High values of Coefficient of determination and Nash–Sutcliffe
efficiency indicate that model can be successfully used for flow simulation in the Betwa basin.
Keywords: River basin planning, HYMOS, monthly simulation, synthetic discharge, water

1. Introduction
River basin development planning and management support integration of watershed,
groundwater, land use, river regulation (by dams, barrages), welfare improvement, healthcare,
and most aspects of development (Gourbesville, 2008). An obvious and often laborious first
step in the analysis, to support such planning and management, is the collection and
processing of available data on the physical properties of the system (Linden, 1989). Thus, in
planning and managing the water resources of a river basin, simulation model is needed to
estimate benefits and other impacts of an alternative and scenario development. Hydrological
Modeling System (HYMOS) is a processing system for hydrometeorological data which
arranges a convenient structuring of data and provides a large number of tools for processing
of data meeting the international standards, (WMO, 1985). The simulation of the rainfall
runoff process in a catchment aims at: fillingin and extension of discharge series; generation
of discharge series from observed rainfall; real time flood forecasting; and determination of
the influence of a changing land/water use.
There are ten River basins (Betwa, Mahi, Chambal, Sind, Ken, Tons, Sonn, Narmada,
Wainganga and Tapi) in Madhya Pradesh which provides irrigation and other benefits to the
state. A large number of medium and minor irrigation projects have been developed in the
state. However, these irrigation facilitating river basins are in a poor state, primarily due to
