Px: Average of the rainfall data
N: No. of data
Tr: Return period (Year)
Px: Average of the rainfall data = Σpi/N
N: No. of data
SD= Sqrt(Σ(pi-px)2 / (N-1)
SD: Standard Deviation
PTr=px+KSD
PTr: Estimated max 24 hr rainfall for specified period
Tr
K=[ -(√6) /π] * [0.557 + (ln(ln (Tr / (Tr-1))]
P Tr3 = 62.21 + (0.27) 29.67 = 70.22 mm
P Tr5 = 62.21 + (0.73) 29.67 = 83.87 mm
P Tr10 = 62.21 + (1.32) 29.67 = 101.37 mm
P Tr25 = 62.21 + (2.06) 29.67 = 123.33 mm
P Tr50 = 62.21 + (2.61) 29.67 = 139.64 mm
P Tr100 = 62.21 + (3.15) 29.67 = 155.67 mm

Tc=0.01947L0.77S-0.385
Tc: Time of concentration (hr)
L: Length of the stream (m)
S: Slope
Q=(P-0.2S)2/(P+0.8S)
Q: Monthly Runoff (mm)
P: Monthly Rainfall (mm)
S: Detention
S= (25400/CN)-254
CN: Runoff Curve Number (from table)
QPeak=0.0208 AQ/Tp
QPeak : m3/s
A: Area in Hectares
Q: is in (cm) from equation (P-0.2S)2/(P+0.8S)
Tp=0.6Tc+ √Tc
Tp: Time to Peak in (hr)
Tp = 0.6Tc + √Tc
Tp = 0.6(1.292) + √1.292
= 1.91 hr

)Reservoir Sedimentation Calculation(
Universal Soil Loss Equation (RUSLE)
A= R*K*LS*C*P
Where:
A: Computed Soil Loss per unit area
(Ton/Hectar/Year)
R: Rainfall erosion index

Procedure of
Calculating Slope
Length Factor
1- Divided the Whole catchment to sub catchment
2- Calculate area for each Sub catchment area
3- calculate Slope length using equation below:

Design and Analysis by Prokon 2.6 software
Analysis of Earth Dam Slope Stability
1- Select Geotechnical
2- Select Slope BG
3- From Table No. (7), select U/S and D/S slopes

4- From Table No. (8), select α and β:
5- Draw Dam Section with scale, and draw lines ac-
cording to Figure No. (14), to get line of center of
Critical Slip circle, then chose center of critical slip
circle on line, at least two points over O1 and two
points under O1, then use coordinates, X,Y, and Radi-
us (R) on Prokon 2.6 to determine Factor of Safety for
each point:
