The unplanned spread of cities across Pakistan is a significant issue that has spawned several grave problems, including urban floods. In light of the repeated devastation it causes, it has become vital to understand how to avoid floods in Pakistan and execute the necessary precautions.
Every year during the monsoon season, the nation is devastated by catastrophic floods.
The most intelligent property site in Pakistan, Park Green City, gives thorough information on actions that may be followed to mitigate the effect of future floods.
Flood-Prone Regions in Pakistan
Even though severe rainfall may cause floods at any time of the year, the monsoon season offers months of persistent precipitation. This is when floods catastrophes occur most often.
Not everything in Pakistan is affected by this disaster. There are certain regions that are afflicted by it for a variety of causes.
Heavy rains may create flash flooding in mountainous regions and urban flooding in plains, particularly in the main cities of Sindh, Punjab, Kashmir, and Khyber Pakhtunkhwa.
Multiple districts of Sindh, including Karachi, Hyderabad, Dadu, Larkana, Sukkur, Thatta, Badin, Tharparkar, and Jacobabad, are frequently affected by floods.
Balochistan, the largest province in Pakistan by land, is always in risk of floods. Recent flash floods induced by storms in the Lasbela region triggered the failure of two dams under water pressure, resulting in flooding in the province’s rural districts.
Key Considerations for Preventing Floods in Pakistan
In order to avoid floods in Pakistan, the government and the general public may take the measures outlined below. These include:
- Regular maintenance of storm drains
- Property arrangement for storage tanks
- augmentation of plantation
- The building of dams
- Maintaining a supply of dewatering pumps and equivalent equipment
Regular Maintenance of Storm Drains
Inadequately constructed drains may overflow during times of intense precipitation. Eventually, they may get blocked with debris, preventing water from draining correctly.
Maintaining clean storm drains may facilitate the disposal of surplus water and reduce the probability of it pooling on the ground.
Arrangement of Property for Storage Tanks
Proper regulations should be enacted to prevent government buildings and business chains from diverting surplus water onto highways.
The installation of water storage tanks (rainwater collection systems) is a straightforward method for controlling surplus water. These storage tanks may be readily erected in all cities, although Lahore and Karachi need them the most.
This will assist in urban floods prevention and groundwater management.
Government tree planting is a crucial action that not only improves the environment but also prevents floods. Eucalyptus and mangrove trees are very effective in preventing flooding.
Eucalyptus trees are fast-growing and effective pesticides. They are also known as the “thirsty tree” of nature because to their extensive root system. This aids with water absorption, similar to the way mangroves do.
By planting these trees near rivers, canals, and dams, they may assist lower the force of tidal waves, so guarding against flooding and tsunamis.
The building of dams
Dams are the best way to avoid flooding in any location, since they are the largest water storage facility for saving water for consumption.
Every year during the monsoon season, flooding occurs in Pakistan since the country lacks adequate dams. Across the nation, modest and huge dams must be constructed to hold surplus water and avoid future flooding catastrophes.
Stocking Dewatering Pumps and Similar Equipment
Dewatering pumps and other equipment required to drain water from roads, buildings, etc., should be readily accessible so that they may be used immediately after heavy rains in locations where they are required.
Methods for Preventing Floods in Pakistan
Using integrated flood control measures, the government of Pakistan has developed a strategy to manage the country’s annual floods.
These comprise structural and non-structural flood safety measures for preventing floods in Pakistan, taking into account the deficiencies identified in prior flood protection schemes. These guidelines are part of the National Flood Protection Plan-IV for the period 2015-2025.
Effective flood control plans include coordination between a variety of stakeholders, including local communities, flood victims, financing organisations, non-governmental organisations, and all levels of relevant government agencies (national, provincial, and local).
A comprehensive summary of flood control measures from the National Flood Protection Plan-IV is provided here.
Understanding the Difference Between Rural and Urban Flooding Prevention Techniques
Strategies for flood protection might vary depending on the kind of location. Traditional engineering methods, paired with distinct pipe networks, cannot be used in metropolitan environments without prior planning. These integrated systems may aid in the management of water drainage (sewer water and stormwater in the same pipe) and the catastrophic impacts of urban floods.
To combat flooding in semi-urban regions, urban drainage systems may be integrated with dams and other forms of storage systems.
However, approaches in rural regions might vary significantly. In such locations, there are less resources and nearly no adequate sewage management systems, allowing the residents to devise their own inventive solutions.
Building tiny ditches or a dike to channel water away from your land, for instance, is a smart practise. In locations where rural flooding occurs, sump pumps might be beneficial.
These little measures may go a long way toward averting disastrous scenarios during monsoon season’s catastrophic flooding.These strategies for preventing floods in Pakistan might significantly mitigate the devastation caused by flash floods now happening in the nation, if not eradicate them entirely.
