PULSE: Model-Estimated Ground-Water Recharge and Hydrograph of Ground-Water Discharge to a Stream PART: A computerized method of base-flow-record estimation RECESS: A method for analysis of streamflow recession. The mean annual recharge of Al-Khazir Gomal Basin was estimated as a basis for decision makers regarding the renewability and sustainability of groundwater.
For this purpose, two approaches were used: hydrograph analysis and water table fluctuation (WTF). The long-term mean daily stream-flow records of Al-Khazir River (–) were used to estimate Cited by: A.

Certainly the most common method of assessing ground water discharge to streams is to separate a stream hydrograph into baseflow and quickflow and then assume that baseflow represents ground water discharge (Winter, ).
If hydrographs are not available, current meter measurements may be taken under low-flow conditions, and the difference in Cited by: Model-estimated ground-water recharge and hydrograph of ground-water discharge to a stream / (Reston, Va.: U.S. Dept. of the Interior, U.S.

The GFLOW model domain includes all major drainage basins in the vicinity of the Bayfield Peninsula, ranging from the Bois Brule River in the west to the Bad River in the east (fig. Other surface-water features include Lake Superior to the north and several lakes and streams to the south.
Optimal hydrograph separation (OHS) uses a two-parameter recursive digital filter that applies specific conductance mass-balance constraints to estimate the base flow contribution to total streamflow at stream gages where discharge and specific conductance are measured.
OHS was applied to U.S. Geological Survey (USGS) stream gages across the conterminous United Author: Sydney S. Foks, Jeff P. Raffensperger, Colin A. Penn, Jessica M. Driscoll. Hydrograph separation techniques range in complexity from graphical approaches that separate the hydrograph into base flow (a proxy for groundwater discharge to streams) and runoff components using only a record of stream discharge (e.g., recession curve [Barnes, ] or digital filter [Nathan and McMahon, ] methods), to two‐component Cited by: Base flow (b) and runoff (Q Stream – b) estimates served as proxies for groundwater and runoff discharge to the stream, respectively, and are hereafter referred to as groundwater discharge (Q GWD) and runoff discharge (Q RO).
Lumping of many different flow paths into these two end‐members is a simplification of the system, necessitated by Cited by: Therefore, we replaced the ground-water component of SWAT with the more detailed and sophisticated ground-water simulator MODFLOW.
The linkage between the two programs is shown schematically in Fig. 3, and is intended to represent the significant interactions among a watershed and its stream network and the associated aquifer according to the Cited by: The activities eligible for the grant program include research, planning, ground water assessments, demonstration programs, enforce- ment, technical assistance, and education and training to protect the quality of ground water and to prevent contam- ination of ground water from nonpoint sources of pollution.
Carmel watershed, the model- estimated groundwater phosphorus concentration is mg/L. The GWLF manual provides estimated backgroundgroundwater phosphorus concentrations for ≥90% forested land in the eastern United States, which is mg/L. Consequently, about 60% of the groundwater load ( lbs/yr) can be attributed to naturalFile Size: 2MB.
Understanding ground water flow on an aquifer or basin scale became possible with the analog model in the s. Improvements in computer technology in the s and s led to the development of digital computer models or numerical models of.

High seepage loss rates along a stream are indicative of focused groundwater recharge [Winter et al., ].Seepage controls mixing between surface water and groundwater, which is important for biological cycling of .Unlike past work that considers estimates of groundwater recharge and river flow as measures of supply, we use precipitation as the renewable water supply endogenous to the area, and consider natural and human uses of this water.
The reliance on imported river water or mined ground water is exposed in the process.
