b
380 structures are coming under the purview of the flood plain area of Rispana river spread over 77.7 hectares from Shikharfal to Mothrowala in the capital Dehradun. These include kutcha and pucca houses and shops. The cabinet on Tuesday gave the green signal to the proposal to issue the final notification of the flood plain area of Rispana. After the notification is issued, pillars will be installed by the irrigation department for demarcation in the flood plain area.
In Uttarakhand too, flood plain areas of rivers are being notified in sequence of the orders of the National Green Authority. In case of flood in the river, how much area can be engulfed by its water is called the flood plain area.
To notify it, the maximum impact area of flood in 100 years and 25 years is assessed. Flood plain areas are notified on this basis. In this, no work including permanent construction can be done which obstructs the flow of water. If any work is necessary, then permission will have to be taken for it.
Efforts were started two years ago
Efforts were started two years ago for the flood plain area of Dehradun’s Rispana river, which is now going to flourish. The flow area of Rispana is 22.5 km from its origin Shikharfal to Mothrowala. On both its banks, 77.7 hectares has been declared as flood plain area as per the assessment of the frequency of flood in 100 years and 72 hectares as per the last 25 years.
The spread of the river has been estimated from 9.97 meters to 100 meters. If we look at the frequency of 25 years, the maximum flow of water in this river has been 35 cumec in Shikharfal and 208 cumec in Mothrowala. As per the frequency of 100 years, it has been 71.5 cumec in Shikharfal and 364 cumec in Mothrowala.
