Which type of rainfall is caused by mountains in the way?

What is peak rainfall mean?
The peak rainfall is the highest amount of rain in a place on a hydrograph.
What does the lag time showon a hydrograph?
It shows us the time between the peak rainfall and peak discharge. Peak rainfall is the highest rain amount. Peak discharge is the highest the water level reaches in the river.
Why is there a lag time between the peak rainfall and peak discharge on a hydrograph?
because there is
When was the peak rainfall?
500 years ago
How do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
Why the peak landslide activity occurs later than the peak rainfall activity?
Landslide activity happens when the hillside has become supersaturated from the peak rainfall activity and can no longer absorb any more water. The weight of the hillside, along with not enough anchoring trees or plant life to hold it, causes the slippage of the mud.
How can rainfall data help in the design of drainages?
during the design of drainage, the rainfall data provides the designer rainfall factor. the area of the site or tributary area is given. the volume of water within the tributary area is equal to rainfall depth and the tributary area also it helps to estimate time of concentration and peak runoff rate it is important to design of drainage

What is the benefit of an attenuation pond?
An attenuation pond is a pond which is designed to slow the passage of water from surface run-off to the ground/drainage system e.g. stormwater sewers. It does this by storing the run-off during times of peak flow i.e. heavy rainfall, and slowly releasing it at a controlled rate after the peak flow has passed.
