How heavy rainfall causes problems in Pakistan?

How can heavy rainfall affect people?
Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.
How does monsoon affect Pakistan?
Monsoon season is a major weather system that brings a huge amount of rain (and thus freshwater) with itself. Monsoon winds carrying rainclouds enter Pakistan from east/north-east side and cause massive amounts of rainfall in north and northeastern regions of Pakistan.
What are the impacts of heavy monsoon?
Because regions with a monsoon climate have distinctly wet and dry seasons, they are prone to floods and droughts, both of which are hazardous to health. During summer monsoons, heavy rainfall can cause flooding.
Why does Pakistan have a lot of rain between June and September?
Following are the main factors that influence the weather over Pakistan.

What are the effects of too much rainfall?
Excessive rainfall can affect crop productivity in various ways, including direct physical damage, delayed planting and harvesting, restricted root growth, oxygen deficiency and nutrient loss, the researchers said.
Why is heavy rainfall bad?
Precipitation extremes create many safety hazards and health risks. Living with poor air quality and in damp conditions has been shown to increase health problems. These health problems include aggravation of asthma and other upper respiratory tract symptoms such as coughing and wheezing due to mold exposure.

Half of the annual rainfall occurs in July and August, averaging about 255 millimeters in each of those two months. The remainder of the year has significantly less rain, amounting to about fifty millimeters per month. Hailstorms are common in the spring.
What causes heavy rainfall?
More heavy rain is one of the hallmark signs of climate change. As the atmosphere warms, more water evaporates from soils, plants, lakes, and oceans. So when this additional water vapor condenses into precipitation, it leads to heavier rain — or when cold enough, heavier snow.
How Pakistan is affected by climate change?
In Pakistan, climatic changes are expected to have wide-ranging impacts, such as: reduced agricultural productivity, increased variability of water availability, increased coastal erosion and sea water incursion, and increased frequency of extreme climatic events.
How does heavy rainfall cause flooding?
Heavy rainfall – if there is heavy rainfall there is less chance of it being soaked up by the soil (infiltration ) so it runs off into the river. The faster the water reaches the river, the more likely it will flood. This will increase the flood risk, as the water will not be intercepted and flow into the river.
