A method for determining the optimal Sustainable Urban Drainage Systems (SUDs) combination at city scale is presented in this paper. A comprehensive set of SUDs categories comprising infrastructures aimed at either detaining and locally reusing or infiltrating precipitation are considered. A volumetric water balance is proposed for modelling hydrological processes in urban catchments. A multi-criteria approach combining a cost function and aims for both recharging aquifers and limiting runoff contribution to water courses is proposed to find the optimal SUDs combination. The water balance was run with each possible SUDs combination and the optimal set of SUDs was found. The method was applied to the Metropolitan Area of San Luis Potosí (Mexico). The optimal solutions in this case clearly promoted surface runoff detention and reuse over porous pavements and green roofs but they were sensitive to the considered costs. The SUD requirements to potential new urban developments for each catchment to comply with the original hydrological aims were also studied. The method requires customizing the cost function and using representative climatic data.

Urban Catchments

Surface waters and urban drainage systems are usually studied separately. However there are important interactions between both systems. Urban drainage systems can have an important impact on the surface waters, mainly at combined sewer overflows. On the other hand during periods of high water levels in a river, the runoff from the urban drainage system can be significantly influenced by backwater, which increases the probability of flooding in is not obvious, because the modelling tools for both systems are often hard to combine properly. To properly assess the probability of flooding for this kind of integrated water systems, different submodels are needed for both subsystems. In practice often one single model is used to describe the runoff to rivers despite the presence of urban catchments. The main objective of this study is to show the limits of this simplified approach. Furthermore, it is necessary to use continuous long term simulations, because of the differences in runoff behaviour. Detailed hydrodynamic models do not really fit for this purpose because of long simulation times and high demands in memory and disk space. Therefore simplified conceptual models are more useful.

The Impact

AbstractSustainable urban drainage systems are multi-functional nature-based solutions that can facilitate flood management in urban catchments while improving stormwater runoff quality. Traditionally, the evaluation of the performance of sustainable drainage infrastructure has been limited to a narrow set of design objectives to simplify their implementation and decision-making process. In this study, the spatial design of sustainable urban drainage systems is optimized considering five objective functions, including minimization of flood volume, flood duration, average peak runoff, total suspended solids, and capital cost. This allows selecting an ensemble of admissible portfolios that best trade-off capital costs and the other important urban drainage services. The impact of the average surface slope of the urban catchment on the optimal design solutions is discussed in terms of spatial distribution of sustainable drainage types. Results show that different subcatchment slopes result in non-uniform distributional designs of sustainable urban drainage systems, with higher capital costs and larger surface areas of green assets associated with steeper slopes. This has two implications. First, urban areas with different surface slopes should not have a one-size-fits-all design policy. Second, spatial equality must be taken into account when applying optimization models to urban subcatchments with different surface slopes to avoid unequal distribution of environmental and human health co-benefits associated with green drainage infrastructure.

Objetivo Comprender las percepciones y experiencias que usuarias de distintos servicios de salud han desarrollado respecto a las limitaciones sanitarias para la promoción de la Lactancia Materna.Metodología Investigación cualitativa con enfoque fenomenológico. Se aplicaron entrevistas en profundidad a 12 madres que habitan en una comunidad clasificada con alto nivel de marginación en San Luis Potosí, México, cuyos partos fueron atendidos en servicios de salud públicos, privados y de seguridad social. Se realizó análisis fenomenológico sobre las entrevistas trascritas en totalidad.Resultados Con independencia del tipo de atención sanitaria, las mujeres reciben poca capacitación para la lactancia durante la etapa prenatal y la mayor parte de esta ocurre de manera impersonal. La mayoría narra experiencias de exigencia y juzgamiento, más que de consejería, por parte del personal de salud.Conclusión La lactancia materna es contemplada como derivada de una decisión personal e individual, en la que no impacta la consejería del personal sanitario. Es necesario impulsar procesos de capacitación y sensibilización dirigidos a fortalecer las habilidades de acompañamiento para la Lactancia Materna en el personal de salud, con el fin de ejercer la función de consejería de manera asertiva.

El reporte de nuevos registros de distribución de especies incrementa el conocimiento biológico de la especie y del sitio donde se registra. Reportamos la presencia por primera vez del Martín pescador enano (Chloroceryle aenea) en Tamaulipas, dentro del Área Natural Protegida Laguna La Vega Escondida, en el paraje Casa de la Naturaleza. Aunque esta especie tiene amplia distribución desde el sur de México hasta el noreste de Argentina, este registro representa el encuentro más norteño para la especie en un ambiente acuático asociado al sistema lagunar del Tamesí, Tamaulipas, y amplía su distribución por más de 135 km de los registros de San Luis Potosí y a más de 160 km de los de Tuxpan, Veracruz.
