What monsoon 2022 left for Balochistan? Balochistan needs speedy rehabilitation of canal system, examination of all dams

on 06/01/2023

Now that the sky is blue after an unprecedented spell of monsoon in Balochistan has come to an end, scars of such heavy downpours left on the province are becoming visible, and demand for a swift rehabilitation process in the province.
A presentation made by a senior engineer of Balochistan Engr. Nasir Majeed in a major moot of the Water Resources Thinktank of Pakistan Engineering Council (PEC) revealed that the monsoon rains which broke historic records of downpours severely damaged the canal irrigation system of the province.
Since this system is the backbone of the province and irrigates one million acres of land in the Naseerabad Division, Balochistan demands the restoration of the system immediately.
The moot in which another senior engineer of Balochistan Engr. Salam also participated in the province demanded that a team of Water Experts from the Pakistan Engineering Council (PEEEC) or well-reputed consultants at the national level may be constituted to review the hydrological and structural design parameters of all small and medium dams of the province to make recommendations for future planning by considering the climate change factor and recommend guidelines for the safety of the dams to sustain such abnormal rains.
The presentation further said:
A new Plan of Flood Management be developed/designed for low-lying & vulnerable areas which are always under threat, by considering all safety factors due to Climate Change.
The present capacity of the irrigation drainage canal is 2600 Cusecs, Which may be enhanced up to 6000 Cusecs to cater to flood water safely.
All the Hill Torrents hitting directly to the Canal system be properly managed through flood harvesting structures to mitigate damages.
It said Balochistan is highly vulnerable to climate change impacts given its inherent aridity and low and erratic precipitation. Severe droughts were recorded from 1973 to 75, 1998 to 2005, and 2009 to 2018.
The median annual rainfall ranges from just over 200 mm in the northeast to less than 50 mm in the southwest of the province. Generally, humidity is low ranging between 20-40%. So the Province falls in the arid zone.
Engr Nasir Majeed said all major dams and structures for storing water in Balochistan are safe. However, the rains have damaged many structures of these projects.
He indicated 19 works that he said should be taken on an emergency basis as restoration and improvement were required. These include the restoration and rehabilitation of three canals and a drainage system in Naseerabad, Jaffarabad, and Sohbatpur.
In Lasbela, the construction of Gagoo & Bela Town Protection Bund and the Rehabilitation of Tharrha Bund Bela Town is required.
In Harnai, Flood Protection Structure for Killi mirza and Killi lal khan, Killi ghareebad, Killi Marpani and Killi zawi, in Kech, Restoration and Improvement of Flood Protection Bund Left Bank of Kech Kaur, in Nushki, Restoration of Flood Protection Bund & Cunnet Killi Qadirabad and Restoration of Spillway Gazool Dam, Azdha Khol & Rako Dam, in Gwadar, Restoration of Ballar Dam Saddle Bund are required. Likewise, ten other restoration and rehabilitation works have also been indicated. – ER Report
