Understanding the Unpredictable Monsoon Flooding
The monsoon season (late June to early September) has traditionally been associated with heavy rainfall, leading to floods in the region. However, what has changed? Why are the floods now so unpredictable, resulting in greater loss of human lives, livestock, and property?
An expert of weather and water Dr. Hassan Abaas in the video below elaborates on these issues. Here are the key takeaways from the video.
* Weather fluctuations are a natural occurrence and have followed the same patterns for centuries.
* Rivers once flowed through their natural paths without causing destruction; however, urban expansion has encroached upon riverbeds.
* Climate change represents an increase in energy, resulting in more energy present on the planet.
* An increase in water vapor leads to the formation of heavy clouds, which can result in cloud bursts.
* The issue isn't the volume of rainwater but rather the intensity of rainfall over a short period.
* Pakistan does not face a water shortage; assumptions regarding a lack of water are unfounded.
* The Indus River is unique as its water sources are derived from glacier melt, snow melt, and rainfall, with a fourth source known as base flow. In the plains, flood water absorbed into the land joins the river after the monsoon, ensuring it never runs dry.
* The delta of the Indus River creates an ecosystem that mitigates land erosion.
As we continue to develop land, the riverbeds and other water sources are diminishing, leading to severe flooding.
*It is essential to exercise caution in our development plans and establish new land regulations.
* Pakistan requires water management experts, yet we currently lack qualified individuals. No universities offer master's level courses in hydrogeology.
* Pakistan’s water management specialists are primarily civil engineers or politicians, who do not possess qualifications in hydrogeology.
* It is not feasible for India to restrict more than 5% of Pakistan's river water due to geological factors; claims regarding water stoppage are misleading.
