The study deals with the development of an operation policy for the Tawa dam. It adopts rule-curve based policy for conservation regulation of the dam developed for three levels viz. upper rule level, middle rule level (critical for irrigation) and lower rule level (critical for water supply and upstream use). The generated simulation model developed by the Water Resources System Group at the National Institute of Hydrology is used to simulate the system operation and to refine the rule curves.

The study deals with dam break analysis of Barna dam located in the state of Madhya Pradesh carried out using the popular National Weather Service Dam Break Flood Forecasting (NWS DAMBRK) model to assess the likely maximum flood discharge and elevation to be attained in Bareli township, 22 km downstream of the dam.

The report deals with estimation of evaporation losses from water surface in Tawa reservoir in Hoshangabad district of Madhya Pradesh. The study is third in the series of evaporation studies to assess the adaptability of different methods for estimation of evaporation from free water surfaces in semi-arid areas. The estimates of evaporation from free water surface obtained by four methods namely Penman, Kohler, Van Bavel and Morton are compared with observed pan values on monthly, seasonal and annual basis.

The study deals with identification of water quality monitoring sites on Kshipra river of Ujjain. The location of permanent sampling station is probably the most critical factor in a monitoring network which collects water quality data. If the samples collected are not representative of the water mass, the frequency of samplings as well as the mode of data interpretation and presentation become inconsequential.

The report presents infiltration studies of the year 1996-97 for the Bargi Left Bank Canal Command area of Narsinghpur district of Madhya Pradesh. Infiltration studies are mainly addressed to a variety of applications for managing water resources. The design of methods for estimation of flood mitigation and erosion control is often based on estimates of peak discharge derived from prediction of infiltration rate. Water conservation procedures require computation of cumulative infiltration to produce estimates of runoff yield.      

In this report, an application of kriging technique is presented for interpolation of groundwater levels in Sagar district of Madhya Pradesh. Groundwater management is important to meet the increasing demand for domestic, agricultural and industrial use. Various management measures need to know the spatial and temporal behavior of groundwater. Most of the groundwater models require the inputs to be available on a grid pattern. However in the field, these parameters are generally measured at random points. However, interpolation of parameters at the grid nodes is a prerequisite for using this data in groundwater modeling.

The report presents a hydrochemical study of the groundwater of Sagar, Madhya Pradesh carried out during 1996 to examine the suitability of water for drinking and irrigation purposes. Under the study, thirty-five water samples representing the shallow groundwater of the region were collected during pre-monsoon and post-monsoon seasons in the month of June and November 1996 respectively.

The report attempts to identify sampling sites for water quality monitoring in Narmada basin. The assessment of water quality conditions over a wide area with respect to time and space requires the monitoring of activities to be carried out in a network. The location of a permanent sampling station is probably the most critical factor in a monitoring network which collects water quality data. If the samples collected are not representative of the water mass, the frequency of sampling as well as the mode of data interpretation and presentation becomes inconsequential.

Dr. G. D. Agrawal Scientist and Rishi

Meeting Dr. G. D. Agrawal in his spartan, two room cottage in Chitrakoot, Madhya Pradesh, you would never guess what an accomplished and distinguished scientist he is – first Member-Secretary of the Government of India’s Central Pollution Control Board, former Head of the Department of Civil and Environmental Engineering at IIT Kanpur and a PhD from the University of California, Berkeley. The list goes on and on.

Yet this eminent professional sweeps his own floors, washes his own clothes and cooks his own meals. He retains only a few possessions and dresses in homespun khadi. At the age of 76, his main mode of transport within Chitrakoot is a bicycle and when he travels further afield, he goes by ordinary bus and second-class train. These are the deliberate choices of a devout Hindu whose deepest values are for simplicity and reverence for nature. Dr G.D. Agrawal is the doyen of environmental engineering professionals in India. Well past retirement, he continues to teach and inspire students as an Honorary Professor of Environmental Sciences at the Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, in Chitrakoot (M.P.).
