Let's solve the problem step by step:
---
### **Step 1: Calculate Change in Water Storage Each Month**
The change in water stored in the basin each month, ΔS, can be calculated as:
\[
\Delta S = P - E - Q
\]
Where:
- \(P\) = Precipitation (mm)
- \(E\) = Evapotranspiration (mm)
- \(Q\) = Runoff (mm)
Let's calculate it for each month:
| Month | P | E | Q | ΔS = P - E - Q (mm) |
|-------|---|---|---|---------------------|
| Jan |250| 5 |150| 250 - 5 - 150 = **95** |
| Feb |205|25 |110| 205 - 25 - 110 = **70** |
| Mar |165|30 | 80| 165 - 30 - 80 = **55** |
| Apr | 50|50 | 5| 50 - 50 - 5 = **-5** |
| May | 5|80 | 0| 5 - 80 - 0 = **-75** |
| Jun | 0|100| 0| 0 - 100 - 0 = **-100** |
| Jul | 0|150| 0| 0 - 150 - 0 = **-150** |
| Aug | 5|70 | 0| 5 - 70 - 0 = **-65** |
| Sep | 10|60 | 0| 10 - 60 - 0 = **-50** |
| Oct | 55|20 | 10| 55 - 20 - 10 = **25** |
| Nov | 65|10 | 15| 65 - 10 - 15 = **40** |
| Dec |190| 5 |120| 190 - 5 - 120 = **65** |
---
### **Step 2: Calculate Cumulative Water Storage**
Assume initial storage is zero at the start of January. Add each month's ΔS to get cumulative storage at the end of each month.
| Month | ΔS (mm) | Cumulative Storage (mm) |
|-------|---------|------------------------|
| Jan | 95 | 95 |
| Feb | 70 | 95 + 70 = 165 |
| Mar | 55 | 165 + 55 = 220 |
| Apr | -5 | 220 - 5 = 215 |
| May | -75 | 215 - 75 = 140 |
| Jun | -100 | 140 - 100 = 40 |
| Jul | -150 | 40 - 150 = -110 |
| Aug | -65 | -110 - 65 = -175 |
| Sep | -50 | -175 - 50 = -225 |
| Oct | 25 | -225 + 25 = -200 |
| Nov | 40 | -200 + 40 = -160 |
| Dec | 65 | -160 + 65 = -95 |

### **Step 3: Answer the Questions**
**a) Month with Largest Water Storage**
- **March** (end): 220 mm (largest cumulative storage)
**b) Month with Smallest Water Storage**
- **September** (end): -225 mm (smallest cumulative storage)
**c) Difference in Water Storage (mm and m³)**
- Difference = 220 - (-225) = **445 mm**
- Convert mm to m³ over 120 km²:
- 445 mm = 0.445 m
- Area = 120 km² = 120,000,000 m²
- Volume = 0.445 m × 120,000,000 m² = **53,400,000 m³**
**d) Likely Climate Type**
- There is high precipitation and high evapotranspiration, with a distinct wet and dry season.
- This pattern is typical of a **humid tropical climate**.
