speed of water arrival, time lag from various locations, flood
prediction techniques. Para 4 in this part deals with flood
warning regarding flood peaks, to assess the downstream
discharges to be communicated to Provincial Irrigation
Secretary. The anticipated discharge for downstream Guddu
is estimated at 600 000-1,200,000 cusecs in the Manual, the
ceilings for downstream Sukkur and Kotri are reduced by
100,000 cusec each, at 600,000-1,100,000 cusecs, and
400,000-1,000,000 cusecs, respectively. The Manual
specifies that as soon as the discharges at the three

obligations, was most crucial at critical stages of

documented. It also shows the bunds that received
prioritized attention and funds.
