recipient reservoirs in real time can provide systems which can solve the
conundrum.
For management of floods, the real-time data is an obligatory requirement.
Wherever the stream is provided with reservoirs of adequate capacity, the issue of
handling the flood safely through the reservoir while maintaining safety and
integrity of the controlling structures is of utmost importance. The operations also
provide the valuable insights about the flood situation downstream and disaster
management operations planning. Critical issue in flood disaster management on
the part of a water resources professional is to provide as long a warning time as
possible for implementing the disaster management operations. Inundation
assessments are another aspect of the assessment of damages that may have
occurred and prioritization of areas for directing relief and rehabilitation operations.
Real-time data collection and transmission has become relatively easy with the
advent of modern satellite-based telemetry and other telecommunication networks
with improved transducers and measurement technologies. Starting in 1997, CWC
has implemented a telemetry network which spans over almost the entire country
and its neighbourhood wherever the bilateral arrangements exist.
In Himalayan regions, the dangers of flash floods occurring due to formation of
land slide dams across streams and also the dangers of breaching of glacial lakes
have been mounting from some time. Assessment of the volumes stored behind
such landslide blockages or in the glacial lakes is of utmost importance for
assessing the dam break floods. Remote sensing technologies with greater spatial
resolutions coupled with digital terrain models have proved to be very good tools
for disaster preparedness and management in the affected areas. Efficient predictions in case of Satluj (2004), Bhote Kosi Nepal (2014) and Zanskar basin (2015)
have prevented loss of lives and damages to costly infrastructures, and the
methodologies have shown maturity. Availability of real-time data coupled with a
pre-computed simulation proves of great value.

Water-Related Database
A comprehensive database is the need of the hour for all the problems of allocation,
planning, implementing and operating the projects. The question therefore arises
that why such a database is not available so far. There are many reasons for
persistence of this problem.
