| Sumario: | The most recent numerical models of urban drainage allow the integration of runoff from roads with the network of sewer pipes, thus evolving towards a holistic version of the system. A fundamental part of this integration is the capture of stormwater in urban drain inlets. These studies have recently increased, resulting in different methodologies to represent the uptake process and making it difficult to apply unified or general formulations. Therefore, this document intends to be a review of the most representative experimental and numerical studies on the capture of rainwater through grates. In addition, the review includes the proposed methodologies for estimating the flow captured by urban storm drains to define a starting point for new and complementary studies to be carried out by researchers, manufacturers, and operators involved in public drainage service systems. Particularly in Latin America, research on the subject is limited even though it is a highly urbanized region. In this context, this document has an additional interest in presenting a particular analysis of the concept of urban drainage in Latin American cities. HIGHLIGHTS
A review of the literature on the hydraulic capacity of drain grates.;
The review presents the methodologies for the estimation of the captured flow.;
We propose the characteristics of a general hydraulic test.;
The bibliographic review includes studies of 3D numerical modeling of grate inlets.;
A critical analysis is carried out on the current challenges of urban drainage for the globe and especially in Latin American countries.; |
