      A regional low flow frequency analysis in the north of Iran using L-moments was carried out. Low flow events have been represented by the 7-day annual minimum series and the L-moments approach was used to assign these data into homogenous regions. According to the homogeneity measure and climatic properties, two subdivisions were found – one in the west of the study area Cited by: The flow duration curve is described here, because the stream health estimation using the eco-deficit and eco-surplus method uses it. A flow duration curve illustrates the percentage of the time, i.e., the probability, that flow in a stream will equal or exceed a particular value. A basic flow duration curve measures high flows to low : Narayanan Kannan, Aavudai Anandhi, Jaehak Jeong.

LOW-FLOW AND FLOW-DURATION CHARACTERISTICS OF ALABAMA STREAMS by J.B. Atkins and J.L. Pearman ABSTRACT Estimates of minimum 7-day average discharges with recurrence intervals of 2 and 10 years for continuous-record gaging stations are presented in this report. Low-flow frequencyCited by: 2.

Feaster and Kathryn G. Lee Abstract Low-flow statistics are needed by water-resource engineers, planners, and managers to protect and manage the water resources of Alabama.

The accuracy of these statisticsCited by: 1. Estimates of minimum 7-day average discharges with recurrence intervals of 2 and 10 years for continuous-record gaging stations are presented in this report.

Low-flow frequency discharge estimates for partial-record stations are also presented. These discharge estimates were computed by relating base-flow discharge measurements at the partial- record stations to daily-mean discharge.

Updating Low-Flow Statistics at USGS Streamgages and Regionalization of Selected Low-Flow Characteristics for Alabama Streams. INTRODUCTION. As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig.

Monthly streamflow statistics have been computed on the individual daily mean streamflows of selected continuous-record stream-gaging stations.

They may be found here: Low-Flow Characteristics of Virginia Streams. Curves describing flow-duration have been developed. This report presents selected low-flow and flow-duration characteristics for sites throughout Ohio.

These sites include long-term continuous- record stations with streamflow data through water year (October 1 to September 30) and for low-flow partial-record stations with measurements into water year The characteristics presented for the long-term continuous-record.

Low-flow characteristics have been determined by the USGS at streamgages in Indiana (Fowler and Wilson, ). Low-flow statistics investigated in that report include the 1- 7- and day. This report shows that differences in geology affect the low-flow ends of flow- duration curves of streams in adjacent basins.

Thus, duration curves aro use­ ful in appraising the geologic characteristics of drainage basins. method for adjusting flow-duration curves of short. In a study of flow-duration curves for Connecticut streams, Thomas () found low flow to be related to the percentage of the drainage basin that is overlain by stratified-drift deposits.

Information on the areal distribution of stratified drift may provide a method to estimate ground-water contributionCited by: Predictive equations for the harmonic mean flow; the 7-day, 2-year low-few (7Q2); and the 7-day, year low-flow (7Q10) of ungauged Texas streams are developed using multiple regression analysis.

Intermittent and ephemeral streams are characterised by natural extended periods of zero flow, which may generally be perceived as the ‘lower bound’ of low-flow hydrology.

The comprehensive literature review performed by Smakhtin () is a benchmark study on low flow hydrology in which low flow was discussed in all aspects.

For characterizing and evaluating low flows, flow duration curves, recession analysis, low flow indices and frequency analysis have frequently been used (Bayazit & Onoz ).Frequency analysis has focused on fitting a theoretical Cited by: 5.

Introduction. Characteristic values of low flow discharge are needed for a number of purposes in water resources management and engineering including environmental flow requirements, water uses and discharges into streams, and hydropower operation (Smakhtin, ).The interest usually resides in characteristic low flow values that represent the long-term average behaviour of low flows Cited by: A flow-duration curve is often used to provide a common base for comparison of streams of different sizes (Graf, ).

A flow-duration curve for a site is developed by plotting the discharge as a function of the percentage of time the flow is exceeded. Low flow analysis Water level and flow control.

Low flow conditions in rivers and streams are of fundamental importance to the ecological status of the change in the seasonal pattern of flows, for example due to exploitation of a groundwater source or abstraction of water from the river, may lead to irreversible changes to the stream ecology.

For specific comparisons of low-flow characteristics, a single point I LAFAYETTE NION on the low-flow cuive is often used, such as the 2-year or year 0 0 i 9 r r s O recurrence interval.

The map shows the location of streamflow gaging I1,E A stations and the value of the 7-day, year low flow in cubic feet persecond for each.Basin characteristics that are generally considered to be fixed through time, for example, elevation, soil type, and physiographic province, are referred to as “immutable” variables.

All basin characteristics were spatially aggregated by the National Hydrography Dataset plus version 2 (NHDPlusV2) by: 3.The relative contributions of quickflow and baseflow components changes through the stream hydrographic record.

The flood or storm hydrograph is the classic response to a rainfall event and consists of three main stages (Figure 1): (i.) Prior low-flow con ditions in the stream consisting entirely of baseflow at the end of a ry perio ; (ii.)File Size: KB.
