Damage with system = $4.2 - $1.47 = <<4.2-1.47=2.73>>$2.73 billion.
#### 336000001. A hydrologist measures a rivers flow rate, which increased by 15% from 500 cubic meters per second to a new rate due to seasonal rains. What is the new flow rate?
The initial flow rate is 500 cubic meters per second.
The new flow rate is 500 + 75 = 575 cubic meters per second.
A geotechnical engineer analyzes a slope with a failure surface area of 150 square meters. If the shear strength is 250 kPa, what is the total shear strength of the failure surface?
The shear strength per square meter is 250 kPa.
A hydrologist studies a reservoir that loses water due to evaporation at a rate of 3% of its volume per week. If the initial volume is 1,000,000 cubic meters, what is the volume after two weeks?
The initial volume is 1,000,000 cubic meters.
A hydrologist monitors a lake that gains 12% more inflow due to a storm, increasing from 800,000 cubic meters. What is the new inflow volume?
