“…In addition, it makes sense from the results that the detention pond algorithm describing multiple outlets (weirs with 2 or more stages) pass more water through the structure at a given time than single stage weir outlet (Figure 4 and Figure 5). In addition, the pattern of detention pond outflow results looks similar to some of the published results from previous studies [12][13][14][15][16]. Therefore, it appears that the developed algorithm for the detention pond is working well.…”

Urban watersheds produce an instantaneous response to rainfall. That results in stormwater runoff in excess of the capacity of drainage systems. The excess stormwater must be managed to prevent flooding and erosion of streams. Management can be achieved with the help of structural stormwater Best Management Practices (BMPs). Detention ponds is one such BMP commonly found in the Austin, TX, USA. The City of Austin developed a plan to mitigate future events of flooding and erosion, resulting in the development and integration of stormwater BMP algorithms into the sub-hourly version of SWAT model. This paper deals with the development of a physically based algorithm for detention pond. The algorithm was tested using a previously flow-calibrated watershed in the Austin area. From the test results obtained it appears that the detention pond algorithm is functioning satisfactorily. The algorithm developed could be used a) to evaluate the functionality of individual detention pond b) to analyze the benefits of such structures at watershed or higher scales and c) as design tool.

Background: Osteoporosis is characterized by decreased bone density that leaves bones fragile and highly susceptible to fracture. Globally, 1 in 3 women and 1 in 5 men older than 50 will suffer from an osteoporotic fracture, and those individuals will experience a considerably higher risk of postfracture mortality than will the general population. Gentle, weight-bearing exercises such as yoga can help prevent or cease the progression of osteoporosis; however, there is insufficient data regarding which yoga poses present the least risk and are most beneficial to individuals with reduced bone density. Objectives: Review the extant literature about the risks and benefits to the spine of particular forms of movement and consider recommendations relative to the practice of yoga. Methods: A review of the PubMed, Medline, and Cochrane databases was conducted that identified manuscripts published between 1966 and 2011 about topics related to osteoporosis and spinal movement. Conclusions: Movements involving spinal flexion can increase risk for vertebral compression fractures; however, a combination of mild spinal flexion and extension may prove beneficial. Moderate, weight-bearing activities that strengthen the muscles supporting the spinal column, promote balance, improve posture, and enhance quality of life appear to be of greatest benefit. Ample evidence supports the importance of varied spinal movement for preserving the health and strength of the vertebral bodies. Exercise modifications suitable for high-risk individuals may be counterproductive for those at low risk for vertebral fractures. Yoga therapists are cautioned to not apply a one-size-fits-all approach when working with this population. Well-designed empirical studies are needed to further our understanding of which yoga poses present the least risk and are of greatest benefit to individuals with osteoporosis.
