“…In the past, this curve was usually approximated by using some empirical equations. For example, Akan and Antoun () and Graber () used a similar form of the storage–stage equation to model detention basins:

s = b h^{c}

where s is the storage of the detention basin, b and c are coefficients that are determined by the geometry and h is the stage. The values of b and c are considered to be constant values, although they may vary for different detention basins.…”

Abstract:The construction of stormwater detention basins is a best management practice to effectively control floods, to provide additional surface storage for excess floodwater and to compensate for the adverse effects of urban development. Traditional field-based levelling survey methods are very time consuming and subject to human-induced arbitrariness and error. This article presents an approach to modelling detention basins measured from light detection and ranging remote sensing data. A case study is illustrated by using the White Oak Bayou watershed of Harris County, Texas. The storage-stage curve obtained from the volumetric analysis is used in a modified detention basins routing model, which was developed by adding the weir structure control to the traditional hydrologic reservoir routing equations. The model simulation showed that the peak flow of the synthetic 100-year reoccurrence event was effectively reduced and delayed by the detention basins. The comparison with the simulation results from the traditional reservoir routing model suggested that previous studies using the reservoir routing model were likely to underestimate the flood reduction effect of detention basins. The sensitivity analysis of the parameters showed that the detention basin design and evaluation should pay more attention on the weir height and river channel's roughness.

Flood reduction constitutes an important characteristic of surface reservoir design. Thus, to ensure that minimum safety standards are met, the Safety Dams Act was approved in 2010. Many multipurpose surface reservoirs are aging and getting out of the current technical standards. In Ceará State, Brazil, there are several dams built for many decades, with spillways sized by empirical formulae which are currently outdated. This article contributes to improve the understanding of the morphological and hydrological factors involved in the process of damping floods in reservoirs and the development of a simple application method that estimates the damping, from such factors. To do so, hydrological simulations of several scenarios representative of reservoir and hydrographic basins configurations were performed. As a result, the impact of each parameter on flood damping was determined. A graphical method was proposed in which all the morphological parameters of the basin and the reservoir were aggregated into a single dimensionless parameter -the Reservoir Damping Index (Φ). With the value of Φ calculated, it is possible to estimate the damping capacity of the reservoir. This method can be used for the design of new reservoirs or for the verification of reservoir spillways already constructed with other methodologies.

“…The existing methods of sizing reservoirs relatively rarely take into account the hydrograph shape (Hager and Sinninger 1985, Akan and Houghtalen 2003, Hong 2009, Graber 2009), and in many methods it is disregarded (Baker 1979, SCS 1986. Moreover, numerous simplifying assumptions in various methods lead to a considerable difference in the obtained results (Szeląg and Kiczko 2014), which in practice hinders the selection of a method appropriate for calculating the required reservoir volume.…”

Abstract:The article presents a method of designing single-chamber rectangular detention reservoirs based on nomographs connecting the parameters and the shape of the infl ow with the reservoir hydrograph (triangular, described by the power function and described by the gamma distribution) as well as the hydraulic characteristics of the accumulation chamber and the orifi ce. The preparation of nomographs involved using the SWMM (Storm Water Management Model) program with the application of numerical calculations' results of a differential equation for the stormwater volume balance. The performed analyses confi rm a high level of similarity between the results of calculating the reservoir volume obtained by using the above mentioned program and using the developed nomographs. The examples of calculations presented in the paper confi rm the application aspects of the discussed method of designing the detention reservoir. Moreover, based on the conducted analyses it was concluded that the infl ow hydrograph described by the gamma distribution has the greatest impact on the reservoir's storage volume, whereas the hydrograph whose shape in the rise and recession phases is described by the power function has the smallest effect.Unauthenticated Download Date | 5/11/18 4:07 AM
