Chapman Alaskan River Forecast Center NOAA, National Weather Service Anchorage, Alaska ABSTRACT Frequent requests to compare current river flow to the normal flow, when to expect spring breakup, when to expect the highest flow of the year, etc., led to a statistical analysis of daily flows at all Alaskan stations for which sufficient discharge records were available. Some of the results were plotted and are presented graphically for quick-look reference. For any given day of the year, the mean flow and the flows that are exceeded ten percent and ninety percent of the time were plotted. The values were taken from a log-normal distribution computed for each calendar day. Examples illustrate some of the uses and interpretations of the graphs. INTRODUCTION Hydrologists in the Alaskan R4ver Forecast Center are frequently asked such questions as: Is today•s flow on the Kenai River higher than normal? When does breakup occur on the North Slope? When would the flow on the Tanana River be expected to be less than 25,000 cfs? The answers to these and other questions are used to make decisions ranging from trivial to critical, some involving large financial risk. They are used in planning activities such as commercial navigation, construction, mining, aerial photography, surveying, moving heavy equipment across ice, recreational boating, fishing, documentary and news photography, and others. The purpose of this report is to present full-year hydrographs of the mean flow for each date, the flow that can be expected to be exceeded nine times out of ten on average for each date, and the flow that can be expected to be exceeded only one time in ten. A secondary purpose is to demonstrate, by examples, how to interpret the hydrographs for guidance in answering questions like the above. METHOD For a given date, say June 15, all the June 15th flows for the number of years of record constitute a sample. No reference to this kind of data set was found in a search of the literature; hence no recommended distribution function was found. Several distribution functions were tested for applicability. The log-normal distribution was selected for a number of reasons, the primary reason being that it fit most samples reasonably well. The Smirnov-Kolmogorov ~-test (Reference 1) for goodness of fit was applied, and very nearly 100 percent of the results were within acceptable limits. Those few that fell outside the limits were thought to be caused by samples not representative of their respective populations. The mean and standard deviation were computed using the equations (Reference 2): x =E.: N s = ru:x 2 ) -(L:x2~/~] 0 •5 L N - 1 where x = logarithm of flow N = number of items in data set ~ = mean logarithm S = standard deviation of logarithms Flows that would be exceeded 10 percent and 90 percent of the time were computed using the equation: log Q10 =! + 1.282S log Q90 =X -1.282S where Qlo = flow that would be exceeded 10 percent of the time Q90 = flow that would be exceeded 90 percent of the time The values 1.282 and -1.282 were obtained from standard tables of area under the normal distribution curve. Thus, for each date, three discharge estimates were obtained and plotted. Some hydrographs contained many sharp peaks and varied greatly from day to day. In most cases this was caused by unrepresentative, small samples from short records, resulting in poor estimates of the true mean, Q10 , etc. Some smoothing was appropriate, but had to be limited so as not to mask features such as the sharp upturn at spring breakup. This limited smoothing was done by taking the sample not only from the record of flows for the given date, but also for the day before and the day after. Thus, for a 5-year record, 15 flow values would be associated with each date; and those 15 values would constitute the sample. Those values would not all be independent; they would only be five triplets of independent items. Nevertheless, this procedure accomplishes desirable smoothing, and has its greatest effect on small 2 samples. It was recognized that a 5-year record is usually too small to yield reliable results from statistical analysis; however, the smoothing procedure tends to make each day's statistics approach its bracketing days• statistics as it seems reasonable to assume would be true of the population's statistics. Five years of record was therefore selected as the minimum. For simplicity, February 29th was skipped (or leaped) as not being very important with regard to flows in Alaska. All the work, from looking up the flow records to plotting the results of the statistical analysis, was done by computer. No adjustments based on judgement were made. INTERPRETATION OF HYDROGRAPHS Shown on the hydrographs in figures 1 and 2 are features that are in common with many other locations in their respective areas. It can be properly deduced that the flow on any given date will lie between the bounding graphs eight times out of ten. If the flow were outside the bounds, the event would be notable, at least. It is not correct to interpret the highest point of the 10%-of~the-time hydrograph as the 10-year flood. The 10-year flood is usually much higher, sometimes several times higher. Conversely, the opposite may be true of the 90%-of-the-time hydrograph and the 10-year drought.

More Examples of Hydrograph Interpretation. 4 Despite the smoothing procedure described earlier, many of the hydrographs still exhibit sharp peaks. It seems reasonable that the graphs derived from the populations instead of the samples would be smooth and would likely pass through something like the middle of the zig-zags. In general, that would be true, but examination of some notable peaks suggests caution. In the examples in figure 2, it was thought that the large September peak at Cooper Landing might be unduly influenced by the record jokulhlaup of 1974, and the August peak at Fairbanks might similarly be a result of the famous 1967 flood. Omitting these events from the samples and recomputing the hydrographs did indeed produce differences. The peaks were only slightly smaller, however, and that suggests that the peaks shown are fair estimates of the true values and should not be smoothed out. On the other hand, the very sharp peak on the Chakachatna River hydrograph (page 43) was caused entirely by one event -one that may occur only once in a geologic age and would be extremely unlikely to recur on the same date. Properly, it should have no influence on a 10%-of-the-time hydrograph. Incidentally, this is one of the very few samples not satisfactorily fitted by a log-normal distribution, which explains the false dip in the 90%-of-the-time hydrograph directly below the sharp peak in the top graph.
