The Indus alluvial plain of Punjab and Sindh provinces in Pakistan is of Quaternary age and is similar to the Ganges alluvial system of India and Bangladesh. The sediments of the plain have their provenance in the western Himalayas and are brought down by the River Indus and its tributaries. The alluvial deposits are widespread and thick (Smedley, 2005) and mostly form unconfined aquifers. However, in contrast to the Bengal basin, the aquifers are relatively oxic (Mahmood et al., 1998 Tasneem, 1999). The area also differs in having a more arid climate and greater proportion of Pleistocene deposits with greater apparent connectivity between the river systems and the aquifers (Smedley, 2005).

Residual and sedentary soils Residual soil is collected from the small, second order, drainage basin (< 100 km2) at a suitable site above its alluvial plain and base of slope, where alluvium and colluvium are respectively deposited. The residual soil may be developed either directly on bedrock or on till, as is the case in glaciated terrains. Residual soil distributed by agricultural activities should be avoided where possible since the top soil is usually affected by human activities. It is important to ensure that the material collected is residual and not transported material such as coluvium or alluvium. 

A floodplain sediment, representing the alluvium of the whole drainage basin will be collected from the alluvial plain at the lowermost point (near to the mouth) of the large catchment basin (1000 - 6000 km2). 

An overbank sediment, representing the alluvium of the small drainage basin will be collected from its alluvial plain near to the confluence point of the small, second order, stream (< 100 km2) with the main, third order, river. 

A study in the Mississippi River Delta (Figure 30.1) during 1995-1997 included surface water samples collected primarily from Steele Bayou, Deer Creek, and Big Sunflower River, which are part of the Yazoo River Basin. This is Mississippi s largest river basin and is divided almost equally between the Mississippi alluvial plain, an intensive agricultural area of soybean, cotton, and rice production, and the uplands, which generally consist of forests, pastures, and small farms (Coupe et al., 1998).

About 80 per cent of ROK are in regions where the altitude of the summit ranges from 300 to more than 1,000 meters. The land bears a strongly dissected relief reworked by numerous erosion cycles. The low lands include both coastal plains clayey materials and the continental alluvial plains and valley flood plans of the interior. 

Downstream of v.Kerki its water is consumed due to irrigation and is lost by evaporation in the flooded alluvial plain.
