Abstract:The present study critically reviews the synthetic unit hydrograph (SUH) methods available in hydrologic literature. The study reveals that the traditional methods of SUH derivation, e.g., Snyder, SCS, traditional methods like Snyder and TS method that does not yield satisfactory results, and their application to the practical engineering problems is tedious and combursome. On the other hand, probability distribution functions (pdfs) based SUH methods are easy to apply, and easily meet the UH criterion, i.e. the area under the curve is unity, and rely on a stronger mathematical base and sounder hydrologic perception. The recent pdfs used for deriving UHs in ungauged catchments, address the SUH shapes with more flexibility than the earlier pdfs proposed by [1] for SUH derivation.

The developed relationships are given as n = 5.53 1.57 +1.04 for 0.01< <0.35; COD = 1 And n = 6.29 1.998 +1.157 for 0.35; COD = 1 (30) Finally, the scale parameter K can be derived from Eq.

“…The resulting hydrograph is shown later in this paper where it is labeled as the "inflow hydrograph" (see Figure 5). The gamma distribution has been shown to be useful for characterizing hydrographs (McCuen and Bondelid, 1983;McCuen, 1989;Kessler and Diskin, 1991), but the only motivation for using it in this study was convenience. Interested readers should refer to the paper by Kessler and Diskin (1991) for a good discussion regarding the use of the gamma distribution.…”

This paper looks at the use of off‐line detention systems as a means of stormwater management. Conventional detention basins are typically designed and built as in‐line systems in which all runoff is directed to the basin. Off‐line systems are designed so that only a portion of the runoff is directed to the basin. Several simulation experiments were run to examine the behavior of in‐line and off‐line systems designed to reduce the peak flow from a developed area to the pre‐development level. The results demonstrate that off‐line systems require considerably less storage than in‐line systems to achieve the same management goal. The results also show that off‐line and in‐line systems have significantly different flow‐duration characteristics with the off‐line system generally producing lower flows over longer periods. Unfortunately, off‐line systems may exacerbate downstream flooding problems, especially when used in the upper portions of a watershed. Nevertheless, an off‐line system can be an alternative to in‐line detention in many cases.

“…The use of a phi-index (CP -index) method in effective rainfall calculations is also well-known (e.g., Kibler, 1982). The S-graph rept'esentation of the unit hydrograph (e.g., McCuen and Bondelid, 1983;Chow and Kulandalswamy, 1982;Mays and Coles, 1980) can be used to develop unit hydrographs corresponding to various watershed lag estimates. The S-graph rept'esentation of the unit hydrograph (e.g., McCuen and Bondelid, 1983;Chow and Kulandalswamy, 1982;Mays and Coles, 1980) can be used to develop unit hydrographs corresponding to various watershed lag estimates.…”
