Most of Punjab and Sindh consist of plain areas.
Plain Area
This plain is spread, in the South of Slat Range and in the East of Suleiman Range and Kirthur Mountain which is spread up to the Arabian Sea. This region is irrigated by river Indus, Ravi, Jhelum, Sutleg and Chenab. Hence it is called the indus plain. The point of Mithan Kot all other reivers join Indus. The plain above Mithan Kot is called the upper Indus plain. The upper part of river Indus is made of teh soil brouth by rivers. So it is very fertile. There are a few rainfalls in it. There is a long chain of canals spread in this area which is unique in the world. Due to these effects good crops are produced over here. In this plain some hills are seen near Chiniot and Sangla Hill. These are not so high to obstruct roads and canals for irrigation. In the West of river Jhelum there is a desert of Thai. This is now irrigated by canals coming from Jinriah Barrage. Due to which a large part of Thai has been populated. There are many Doabas in this region, For Example Ban Doab, Singh, Sagar Doab, Neli Bar in district Multan and Sahiwal, Gunji Bar and Kuruta Bar. As soon as we go away teh plain became higher and higher. This raised region plain called Daras. In the north of Daras, the plains of Bannu and Peshawar are very fertile. Good crops are found here due to canals and tube wells. The important crops of its region are wheat, rice, cotton, sugar cane, tobacco and oil seeds.
The Lower Indus Plain
The region in the south of Mizhan Kot to the Arabian Sea is called the lower Indus Plain. It includes the most part of Sindh Province. This plain is very fertile. In the North of sindh many canals have been dug due to which good crops are produced. The people of this region are becoming rich day by day.The central part of sindh has been irrigated by canals to a large extent, but the eastern part is still desert. It is called the desert of Thar many arrangements are being made for teh progress of this region. Near Thatha, rever indus starts making Delta and is divided into many branches which afterwards fall in the Arabian Sea. During rainy season most of its part is flooded with water and bring large destruction.

Coastal Plain
The length of coastal plain of Pakistan is about 700 kilometers which starts from the border of Sindh with an Indian and ends at Pakistan and Iran in the West. The coastal areas of Pakistan are very important due to its geographical situation. Also the possibility of mineral oil in the sea has increased the importance of coastal regions.

In district sakasar its height becomes 1,500 meters. This is the reason of pleasant weather over here. Although the mountains of salt range are barren but are full or mineral wealth where the reservoirs of salt, gypsum, stone of calcium and coal are present. The famous Khewra Mine of salt is also here. In the north of Salt range is the plateau of Potwar its height is 300-600 meter. The land here is dry and stony. At certain place cultivation is done. Here the reserves of kersone oil are found. Two important rivers flow here. Among them rivers Swan is the larger one. Its valley is called Swan Valley and its famous for old civilization.
