wave. Any wrong or mutilated picture of flood may result in increasing the difficulties and aggravating the situation. (iv) Infrastructure development The general public should be aware of the flood prone areas and may be discouraged to raising any structure within the area. Govt should mark & advertise flood prone areas through the print and electronic media for the information of the public. No utility services like gas, telephone, electricity should be provided in the flood prone areas particularly within the river banks. Proper record may be maintained regarding the raising of building in the specified areas. In the hilly areas where flash flooding usually creates havoc, construction of building should also be disallowed in the vicinity of the hill torrents paths. Similarly edges of the roads near rivers should also be banned for construction of any big structure like shopping centers, educational institutions, hotels, Govt office buildings etc. c:\documents and settings\administrator\desktop\cd material nust\international training workshop\session 5\2_sop pmd_51 pages.doc
FLOOD ROUTING THROUGH MANGLA RESERVOIR (CATEGORY-I FLOODS) 2 TO 5 LAC CFS Annexture -5A 1. Flood built up confirmation at EL 1202 feet 2. Balance inflow, outflow upto high flood limit 150,000 cfs 3. Watch till elevation rises to 1203 feet 4. If inflow still rising increase outflow to 250,000 cfs 5. Watch till elevation rises to 1204 feet 6. if inflow still rising increase outflow to 300,000 cfs 7. Watch till elevation rises to 1205 feet 8. If inflow still rising increase outflow to 300,000 cfs 9. Watch till elevation rises to 1206 feet 10. If inflow still rising increase outflow to 300,000 cfs 11. If reservoir level still rising with: Continue same outflow and a) Evidence of still rising with: then start reducing gradually as the situation permits. b) Evidenc4 of further flood buildup Open the main spillway to cater for inflow / outflow Note: Flood warning station data and FFD forecast shall be kept in view all the time. As soon as inflow hydrograph recession is confirmed the outflows should be reduced gradually for downstream relief, subject to the safety of the project. c:\documents and settings\administrator\desktop\cd material nust\international training workshop\session 5\2_sop pmd_51 pages.doc
