Floods, Flash Floods and Dyke or Dam Failure in Balochistan

Southern parts of Balochistan have always been prone to flash floods. Torrential rains during the monsoon season lead to flash floods almost every year in the districts of Turbat and Gwadar. Shadikor dam near the town of Pasni, usually spills during the season, causing havoc to people, livelihoods and property downstream. The floods are usually worst in three ‘Tehsils’ -Dasht, Ormara and Pasni, in Gwadar district, they caused extensive damage to houses, standing crops, orchards, livestock and water supply schemes affecting thousands of people and settlements while cutting and damaging road networks. There are over 300 dams in Balochistan, many of them have been constructed along the irrigation plains as check dams and delay action dams. The check dams recharge underground water and serve as a source of potable water for the surrounding areas. In the coastal regions of southern Balochistan, dams have bursted in previous years due to heavy rains. Their collapse has led to flooding leaving thousands homeless, destroying hundreds of acres of agricultural land, and causing massive damage to infrastructure. In previous cases, flooding washed away sections of the Makran Coastal Highway, a major transport link, as well as destroying numerous roads and bridges. Telephone and power networks have al so been severely disrupted. Most of the affected areas during the rain season is usually inaccessible for several days, leading to need for relief assistance through other means. The affected districts usually are Pasni, Gwadar, Awaran, and Lasbella. On 10 February, 2005, Shadikor Dam bursted after more than two weeks of heavy rains. Over 130 persons were reported killed. Pasni Township was severely a ffected with over 5,500 people trapped in floodwater and many houses destroyed. Some 40,000 acres of standing crops were completely destroyed due to the dam burst.

Preliminary Monsoon 2015 Outlook for Pakistan

Using local, regional and global data sets up to April, a Preliminary Monsoon 2015 Outlook for Pakistan is prepared for June-July-August. Its salient features are given below:

  1. Pre-Monsoon showers are expected during second fortnight of June and monsoon will attain its normal rhythm gradually toward the end of July.
  2. In general, 2015 monsoon is expected weaker than normal, therefore less than normal rain is foreseen during June-August.
  3. Monsoon rains will mainly concentrate in AJK, Northeast Punjab and upper KP embedded with extreme precipitation events sometimes exceeding 200mm per day.
  4. Models are indicating some heavy falls in catchment of Kabul River in Pakistan and Afghanistan due to interaction of westerlies and monsoon currents.
  5. Due to less cloudiness and relatively clearer skies in GB, glacier melt rate will be higher. A careful operation of dams will be required to avoid the synchronous peak flows.
  6. In Sindh and Balochistan, rainfall during the period is expected to remain much less than normal which may aggravate the drought conditions in Thar and Cholistan.

CYCLONE ALERT Potential Cyclonic Activity in Arabian Sea

In Arabian Sea, the persistence of clouds shows an area of convection with a potential of development of a cyclonic circulation over there. Sea surface temperatures and upper air analysis also point toward the development of a deep low pressure area. The numerical models are continuously indicating such cyclonic activity in Arabian Sea at a distance of 1600 km south of Pakistan coast in next couple of days.
