evaluation of base flow separation methods based on recession analysis
hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...
متن کاملEstimation of the base flow recession constant under human interference
[1] The base flow recession constant, Kb, is used to characterize the interaction of groundwater and surface water systems. Estimation of Kb is critical in many studies including rainfall-runoff modeling, estimation of low flow statistics at ungaged locations, and base flow separation methods. The performance of several estimators of Kb are compared, including several new approaches which accou...
متن کاملNonlinear analysis of flow recession curves
Flow recession curves of rivers are commonly simulated by the equation of a single linear reservoir which is determined by one parameter, the retention constant. In reality, however, retention-discharge characteristics are hardly linear and recession curves can be approximated only sectionwise by linear reservoirs with retention "constant" values which increase while discharge decreases. In the...
متن کاملRecession flow analysis for aquifer parameter determination
The recession flow analysis of Brutsaert and Nieber [1977] extended by Troch et al. [1993] to estimate aquifer parameters (saturated hydraulic conductivity and mean aquifer depth) is examined by means of a numerical model. It is found to be reliable for the estimation of the catchment-scale saturated hydraulic conductivity and mean aquifer depth. Increasing the complexity of the synthetic water...
متن کاملRelating low-flow characteristics to the base flow recession time constant at partial record stream gauges
[1] Base flow recession information is helpful for regional estimation of low-flow characteristics. However, analyses that exploit such information generally require a continuous record of streamflow at the estimation site to characterize base flow recession. Here we propose a simple method for characterizing base flow recession at low-flow partial record stream gauges (i.e., sites with very fe...
