Yamuna

In the light of the recent major floods in river Yamuna, the enclosed article that deals with the question and futility of man made structures like dams and embankments to control floods may be found useful.

But it is unfortunate that even this otherwise very insightful article does not reflect anywhere on the fact that the floods in monsoon months are natural events and should be acknowledged and planned for accordingly.

There is a need to better understand the phenomenon of floods and not to treat them as some kind of natural calamity requiring artificial man made safeguards.

It may be noted that Dr D K Mishra who has studied the floods in river Kosi for decades has been making these points for many years now. It is necessary to heed to people like him if we do not wish to invite more trouble in future.

The study deals with flood plain mapping in a part of Yamuna basin between Gangoh and New Delhi. A flood is a markedly high stage of flow in a river and may inundate adjoining lands, which is called the floodplain of a river. So, floodplain is land inundated by a flood of given frequency. Alternately it is also defined as flat land between valley walls.

Abstract

The study assesses the suitability of groundwater for drinking and irrigation use and examines the likely impact of Yamuna river water quality on groundwater. Delhi is faced with severe problems associated with groundwater quality and quantity. The quality varies spatially and seasonally, with depth and is primarily governed by the extent and composition of dissolved solids present in it. Surface water bodies play a role and the hydraulic gradient determines the lateral and vertical migration in the groundwater flow system.

Groundwater samples were collected through extensive field surveys covering entire Delhi area representing various geo-hydrological and land-use conditions. The data has been analysed with respect to BIS and WHO standards to examine its suitability for various uses. The area has a peculiar feature of infiltration of surface water to groundwater from river Yamuna and from various drains.

The study models the variations in water quality parameters of Yamuna river by means of stochastic approach using Central Water Commission’s monthly data for the period 1990-95 and makes projections for the year 1996. The results obtained for different water quality variables have been compared with the observed values and were found to be satisfactory. 

Delhi, India

I, Gopi Dutt, want to draw your attention to problem that Delhi has been facing since as long as 10 yrs now. I am talking about the pollution in Yamuna caused by devotional material, Polybags, Flowers etc. Our govt., different NGOs and now Maharaja Sri Sri Ravi Shankar have put their best efforts to clean up the river. We all have been trying to clean it up for the past 10 yrs but it hasn’t stopped yet. Does anyone have a plan to stop this that here is no further need to clean n re-clean the river? The problem is that we only create awareness that people should not pollute the river but there are no measures taken to stop this pollution.
