Stormwater source control regulation: a hydrological comparison of alternative policies
Stormwater source control regulations are rapidly diffusing in many countries. Most of these are provisions that limit runoff rates at the parcel-scale, although some references indicate some negative side effects, at the catchment-scale, for this form of regulation. In this paper, we compare, at that scale, the effects of several runoff rate and runoff volume provisions, using a hydrological m...
متن کاملThe impact of stormwater source-control strategies on the (low) flow regime of urban catchments.
Stormwater management strategies increasingly recognise the need to emulate the pre-development flow regime, in addition to reducing pollutant concentrations and loads. However, it is unclear whether current design approaches for stormwater source-control techniques are effective in restoring the whole flow regime, and in particular low flows, towards their pre-development levels. We therefore ...
متن کاملReflection in Nursing Education: Why and How?
Introduction: Nursing education should develop autonomy, critical thinking, open-mindedness and sensitivity to others. Reflection seems to be an effective strategy for developing such capabilities in nursing. Therefore, this narrative review study was carried out to explore reflection in nursing education. Methods: Using keywords like reflecting, reflection and nursing reflection, FarsiandEngl...
متن کاملSand Control: Why and How?
October 1992 nPerils of sand production. At worst, sand production threatens a well. Voids can form behind the pipe, causing formation subsidence and casing collapse. The well may also fill with sand and cease flowing. Or the surface equipment may be catastrophically damaged by erosion or plugging. For help in preparation of this article, thanks to: Bob Elder, Chevron UK Ltd., London, England; ...
متن کاملHydrographs’ attenuation in sewers. Effects on stormwater source control regulation
In this paper we propose an empirical approach to quantify the hydrographs’ attenuation in sewers. The purpose is to evaluate attenuation’s consequences for the scale-transfer between the parcel and the catchment in urban settings, and in particular for stormwater source control (SC) regulation. In fact, SC regulation practices often consider this scale-transfer by a linear approach. We draw a ...
