The frequency analyses enabled estimation of daily discharges at selected exceedance probabilities (EP's), including the EP that was used in design of the flood- storage capacity of Pueblo Reservoir.

  [1] Wavelet analysis is used to identify and describe variability in annual Canadian streamflows and to gain insights into the dynamical link between the streamflows and the dominant modes of climate variability in the Northern Hemisphere. Results from applying continuous wavelet transform to mean annual streamflows from 79 rivers selected from the Canadian Reference Cited by: The results of the study are presented in a report by Sherwood and Huitger (). The database developed for this study consists of geomorphic, basin, and flood-frequency characteristics for 50 study sites in Ohio, of which 40 sites are near streamflow-gaging stations. Field surveys were done at each site to collect the geomorphic data.

Streamflow characteristics. [H C Riggs] -- Reliable estimates of streamflow characteristics are needed for planning, design, and operation of works for providing water supplies and for protection from flooding.

A low-flow frequency analysis using the annual minimum flow (AMF) and the deficit below threshold (DBT) approaches was carried out for 30 hydrometric stations across the province of New Brunswick.

This analysis focuses on parts of the country where streamflow is strongly influenced by snowmelt. Trends are based on the winter-spring center of volume, which is the date when half of the total January 1–July 31 streamflow (in the West) or half of the total January 1–May 31 streamflow (in the.

Systematic-Record Analysis The systematic-record analysis involves the computation of the mean, standard deviation, and coefficient of skewness (, S, and G, respectively) of the common logarithms of the annual peak flows in the systematic record.

Streamflow characteristics and methods for determining streamflow requirements for habitat protection were investigated at 23 active index streamflow-gaging stations in southern New England. Fish communities sampled near index streamflow-gaging stations in Massachusetts have a high percentage of fish that require flowing-water habitats for some or all of their life cycle.

Streamflow statistics are extensively employed for the management and development of water resources. The magnitude and frequency of streamflows in the Susquehanna River Basin (SRB) are often used by the Susquehanna River Basin Commission (SRBC) and other agencies for the purposes of water resources planning and management (SRBC, ).Cited by: 1.

Streamflow measurements are commonly based on water level measurements that are converted to a discharge rate using a rating curve (see Fig. ).The rating curve is constructed based on a sample of streamflows measured using the (time-consuming) velocity–area method and their corresponding water level (concurrent streamflow and water level data sample is termed gauging).

Frequency Analysis of Continuous-Time Signals Skim/Review The Fourier series for continuous-time signals If a continuous-time signal xa(t) is periodic with fundamental period T0, then it has fundamental frequency F0 = 1=T0.

Assuming the Dirichlet conditions hold (see text), we can represent xa(t)using a sum of harmonically related complex File Size: KB.

Then, a local flood frequency analysis is performed on the extracted maximum peak flow series. The proposed approach, referred to as regional streamflow-based frequency analysis (RSBFA), is applied to a case study in the province of Quebec, Canada.

Results indicate that the performance of the RSBFA approach is comparable to traditional by: 6. Then, a local flood frequency analysis is performed on the extracted maximum peak flow series.

The U.S. Geological Survey (USGS) has been measuring streamflow at thousands of streams for over a century. When extensive records of past streamflows exist, it is possible to see a pattern of streamflow variation by month and season. Books at Amazon.

Abstract An analysis was made to determine the amount of annual and seasonal water yield, flow duration, and peak flow frequency for seven major physiographic units in the northeast.

AU watersheds () in the northeast that were less than square miles in area, that had continuous records from toand that were not appreciably.Runs analysis is also a part of the first group of analyses. In this paper, we consider only the low flow series defined as the deviations of the flows below the median annual flow.

For each river we compute the frequency of run lengths below the median, run magnitude and run severity. Details are given in Part 1 (McMahon et al., c).Cited by: General features of ecological/environmental time series Components of a time series Frequency domain analysis-the spectrum Estimating and removing seasonal components Other cyclical components Putting it all together Introduction to Statistical Analysis of Time Series Richard A.
