Programs, Data, Devices andmethods Required



Purpose of the project

1) To predict the ood in the earliestpossible time

2) To minimize the ood by making proper

strategies3) And to store ater in our reser!oirs to the

ma" safe le!els

#) And to e!acuate and displace people ine"treme cases before any life loss$



%o the ood can bepredicted

•

&ollecting data related to the ri!er or 'allah (asin i$e$ Total area slop roughness in*ltration factor and minater carrying capacity of the ri!er at the critical point$

• +ined ma" o ,uantity and the min time for ma" aterconcentration by multiplying area of the basin by the

rainfall intensity hile considering other factors in!ol!ed• +ind the accurate rain fall intensity and transmit data to

the point of obser!er using ad!anced rain gauge

• Predict the situation automatically by comparing the ma"ater o and the ma" capacity of ri!er-'allah using ./

e"cel by using already feed data and transmitted data• 0eporting safe hen the o ,uantity is less then the

ma" capacity of ri!er otherise ring the bell of threat$

able to plan our reser!oirs and headork accordingly

• De may also pro!ide temporarysafety raising banks of the streams
