Australian Rainfall and Runoff, a design guide to flood estimation, recommends a method based on catchment area (tc = 0.76 A0.38) for calculating time of concentration to the catchment up to 250 km2 area (Pilgrim 2001).
A modified elutriation device is developed to measure particle settling velocity distribution for use in stormwater runoff treatment design and performance evaluation.
We present an urban runoff model designed for stormwater managers to quantify runoff reduction benefits of mitigation actions that has lower input data and user expertise requirements than most commonly used models.
It contains a daily time step distributed parameter continuous simulation surface runoff model designed to assist with determining Best Management Practices (BMPs), the setting of Total Maximum Daily Loads (TMDLs), and for risk and cost/benefit analyses.
Gajbhiye et al. 2013a, Mishra et al. 2013 design runoff curve number for Narmada Watershed (India).
In this application, we use the physical model to design runoff control measures to reduce concentrated flow causing gully erosion.
The case demonstrates how uncertainties in measurement and prediction of pollution runoff shape program design and participant perceptions.
They perform reasonably well for the reproduction of rainfall statistics and almost perfectly for the reproduction of runoff and storage design variables.
The drywell with this Ks= 1.01 × 10−3 m min−1 could easily infiltrate predicted surface runoff from a design rain event (∼51.3 m3) within 5760 min (4 d).
Short duration rainfall intensity in Taiwan has increased in recent years, which results in street runoff exceeding the design capacity of storm sewer systems and causing inundation in urban areas.
