The recent rains in Mumbai coupled with high tide of 1st August gave us a chance to have a first hand experience of their expertise. When given the likely timings of High tide on 1st August as well as the stretch prone to inundation, project director of Disaster Management in ISRO was kind enought to divert a Canadian Satellite and take snaps of the area of concern and National Remote Sensing Agency was kind enough to give a preliminary study of terrain using Digital Terrain Mapping. ISRO also has bandwidth availability for VSAT communicatin during disasters (as well as telemedicine) which is linked with cabinet Secretariat, PMO and other monitoring areas. I am sending the report to DFCCA to upload on the site as well a few pictures taken from Canadian Satellite of the focus areas. I am sure my colleagues will certainly think of utilising ISRO's services for satellite imaging, track alignment pattern, remote sensing of scraps lying by the side of tracks, VSAT bandwidht etc. Suggestions are welcome. Warm regards scmitra

Mumbai suburban is prone to floods especially after Grant Road due to poor outlets and if high tides combines with the rains; then we had it. Having had the opportunity to see 26/7 rains and ensuing floods, what you have done deserves and pat on the back. I wish this could be followed up. I am sure DEN/Tracks would be interested only if Sr.DENs could take some interest. I am sure this would long term rewards. This has other implications. The gradients we keep talking about and stalling; which Sr.DMEs keep crying about can be seen in real light. One example. A gradient has been certified as1 in 150, but stalling keep happenning with Gajraj also. Sr. DME alleges that gradient is not 1 in 150. Sr DEN says it is. AEN also gives a certificate and everyone else says it is not. This could be seen in the application you suggested. One question, how does one ask a satellite to move and go around a corner and check a particular band of land? Is it like a car? Regards Vivek Tripathi Sr. DFM, RJT

Space agencies world over have quid pro quo arrangements with other agencies of the world for aid during time of disasters. At that time Canadian satellite was in the zone from which Indian territory was 'zoomable' and hence its camera were configured.Hence what I meant by 'diverting the Canadian satellite' was basically remotely managing/configuring the onboard camera of that satellite which had Indian subcontinent at its 'zooming zone' so that target area could be viewed better. Hope to have made myself clear. scm Last Edited By: scmitra 08/28/08 01:04:40. Edited 1 times.

The diagnosis proposed by the report seemed to pertain mainly to Mumbai to predict acccumulation of water on the track during the monsoons and high tides. In Bilaspur division, we have a tough ghat section route in the Bilaspur-Anuppur section. The problems in the section which are crucial to train safety are boulder fall, bank slips and the formation of cess pools by the side of the track which results in the water seeping into and weakening the formation. Does ISRO have a solution whereby such areas can be identified during the monsoons and remedial action be taken by the engineers? The area prone to these problems is only about 50-60 km long and the stretches prone to these problems have been more or less identified. The strengthening of such areas is also a part of their monsoon preparation. But heavy rainfall on certain days can aggravate the problem in certain areas and information through remote sensing can help in rushing men and material to such sites for taking appropriate remedial action. Kindly provide the addresses, e-mail ids of the scientists concerned in ISRO and NRSA so that I can ask my Sr.DEN (Co) to contact them for providing detailed information on this subject.

I am sure they might be able to help, thugh the extent would be conveyed to me only when they have understood the requirement. I have forwarded this request to Head, Disaster Management, ISRO. I will mail you his id and numbers. Thanks for evincing interest. scm

Anything which increases the throughput and train safety is extremely useful to the Railways in general and our division in particular. This is because the unrestricted movement of freight traffic is crucial in increasing our loading and reducing detentions. I went along with the sectional Sr.DEN (also a good personal friend) on push trolley in the ghat section during the summer and came to know about the problems they face during the monsoons and what preparations they make to counter them. I think if they can help detect those areas which I mentioned in my earlier post, it will help the engineers go about their task in a more systematic manner. Ananth Sr.DFM/BSP
