Environmental tracer methods have been used to quantify groundwater discharge to rivers for the past few decades. A number of different tracers have been used in these studies, including individual ion. projects, especially in small urban streams is dependent on the accurate estimation of the channel-forming discharge. Among the different types of channel-forming discharges, effective discharge (Qe) is the only one that incorporates sediment transport mechanics in its estimation : Asif Quader. subterranean discharge of ground water to sea – first approximation study for orissa Conference Paper (PDF Available) March with 44 Reads How we measure 'reads'. A new analytical method was proposed for groundwater recharge and discharge estimation in an unconfined aquifer. The method is based on an analytical solution to the Boussinesq equation linearized in terms of h 2, where h is the water table elevation, with a time-dependent source by:

Chemical, biological and physical properties of surface water and groundwater are indeed different. In the transition zone a variety of processes occur, leading to transport, degradation, transformation, precipitation, or sorption of by: Equivalent pipe is a method of reducing a combination of pipes into a simple pipe system for easier analysis of a pipe network, such as a water distribution system. An equivalent pipe is an imaginary pipe in which the head loss and discharge are equivalent to the head loss and discharge File Size: KB. applying the different methods is given in Appendix III. Part 11 discusses the application of crop water requirements data in irriga-tionproject planning, design and operation.. Part II. 1 deals deriving the field water balance, which in turn forms the basis for predicting and peak irrigation supplies for general planning Size: 2MB. The hydrological approach requires the consideration of the recharge-discharge cycle of subterranean waters; the water-exchange conditions in the subsurface reservoir; the physical properties of the water-bearing formations; the hydraulics of the aquifer, that is, the hydraulic gradients, velocity of flow, storage capacity, water-yielding ability, static, dynamic, and perpetual water resources, by:

METHODS FOR ESTIMATING GROUND-WATER SUPPLIES the principal species, and,to determine the rate at which they dis­ charge water. Holes should also be dug to investigate the root habits of different species of plants and to determine to what depths their roots extend to reach the capillary fringe and feed on waterCited by: Methods used include geochemical tracers (primarily radon and radium isotopes), water budgets, numerical models, and direct measurements (e.g., seepage meters), and except for the water budget approach, no universal method by: flood-estimation methods, a study using two different flood-estimation methods was made by the U.S. Geological Survey in cooperation with the Iowa Highway Research Board and the Highway Division of the Iowa Department of Transportation.
