Natural streams are always considered as an easy way to dispose-off many kinds of waste water effluent. Sewage water is discharged into the river at some places and under low flow conditions in river, the waste water in channel causes swear hazardous problems to the nearby communities. Thus, its very important to determine the quality and quantity interchanging from river to adjoining flow domain. Present study was conducted near River Ravi at Lahore.Overall results are presented in this technical book. This book certainly enhance learning among researcher, scientists, students and farm...

Groundwater is equally important to meet
the rapidly expanding need in agricultural sector and its
quantification is necessity for efficient and sustainable
groundwater resource development and management. The
availability of recharge estimation techniques differ
climatically and hence need a well-defined methodology for
presenting different recharge processes and its
adoptability after verification of results. Three methods
(Gravimetric, rainfall runoff and water table fluctuation)

Demand of food is increasing day by day
and performance of an irrigation system is associated with
infiltration characteristic of the soil. An extensive
irrigation system is being developed in Greater Thal Canal
area that has predominately coarser soils which results to
higher deep percolation losses than the losses in other
cultivated land. Soil amendments like bentonite have the
potential to be used in reducing infiltration rate and
improving the moisture within rootzone in irrigated
