“…In other hydrological disciplines, a sustainable approach is already being taken in urban areas to minimize anthropogenic influence on the environment. For example, urban planning with LID (Low Impact Development) and SUD (Urban Drainage Solutions) technologies seeks to reduce the risk of stormwater flooding [36][37][38]. Similar concepts should also be implemented to reduce the SUHI effect, as water and energy are critical and essential resources.…”

The subsurface beneath cities commonly shows a temperature anomaly, a so-called Subsurface Urban Heat Island (SUHI), due to anthropogenic heat input. This excess heat has multiple effects on groundwater and energy resources, such as groundwater chemistry or the efficiency of geothermal systems, which makes it necessary to investigate the temporal development of a SUHI. For this purpose, temperature profiles of 38 observation wells in the German city of Nuremberg were evaluated from 2015 to 2020 and the measured temperature changes were linked to the surface sealing. The results show that the groundwater temperatures changed between −0.02 K/a and +0.21 K/a, on average by +0.07 K/a during this period. A dependence between the temperature increase and the degree of sealing of the land surface was also observed. In areas with low surface sealing of up to 30% the warming amounts were 0.03 K/a on average, whereas in areas with high sealing of over 60% significantly higher temperature increases of 0.08 K/a on average were found. The results clearly emphasize that the subsurface urban heat island in its current state does not represent a completed process, but that more heat energy continues to enter the subsoil within the city than is the case with near-natural land surfaces.

“…When flow measurements are not available, calibration methods cannot be used to determine model parameters. Modelers referred to previous studies to estimate their parameter values e.g., [115]. When a distributed model distinguishing the different types of land covers and uses of a certain catchment area is calibrated, the obtained parameters could be considered as physical characteristics of these surface types, providing, therefore, the option of transferring them to other catchments with similar surface types.…”

Quantifying urban runoff during frequent rainfall events is a key element in quality management of urban water due to their high contribution to the annual runoff flow. This explains the growing interest among hydrologists in studying runoff flow on urban surfaces. In this paper, we review most of the experimental approaches as well as the modeling ones conducted in the literature to understand and estimate runoff flow on urban areas. This review highlights the incoherence between our current understanding of the hydrological behavior of urban areas during frequent events and our conception of the loss functions in the urban drainage models. Field studies provided more insight into the determinant processes occurring on the different surface types during frequent events with depression storage being a fundamental element varying between surface types and for the same surface type and infiltration process being relatively important on paved areas especially in their cracks that constitute preferential pathways for rainwater. Analyzing a wide range of urban drainage models showed that these elements along with the temporal evolution of the hydrological behavior of urban surfaces due to seasonal and state conditions are not fully integrated in the models’ structures, which were initially developed for heavy rainfall events. Adapting the assumptions of urban drainage models based on these new factors must improve the performance of hydrological models for frequent rainfall events.

“…Segundo Miguez et al (2018) e Kourtis et al (2018), os conceitos inovadores mais adotados para a readequação dos sistemas de drenagem têm por objetivo retardar o escoamento, de forma a propiciar o aumento dos tempos de concentração e a consequente redução nas vazões máximas.…”

“…Surgem, portanto, tecnologias que consideram outros aspectos do gerenciamento de águas pluviais, como: a qualidade do escoamento superficial; os aspectos paisagísticos; o valor recreativo; e a proteção ecológica da bacia. Essas soluções de drenagem têm sido amplamente aplicadas em diferentes partes do mundo e são denominadas de Soluções de Desenvolvimento de Baixo Impacto ou LID (Low Impact Development) (KOURTIS et al, 2018).…”

Ao longo dos últimos anos, o meio científico tem exposto suas críticas quanto à flexibilidade limitada das soluções convencionais de drenagem no combate às inundações urbanas. Atualmente, novas tecnologias têm surgido com intuito de garantir soluções sustentáveis ao gerenciamento urbano de águas pluviais, sendo chamadas de Desenvolvimento Urbano de Baixo Impacto (Low Impact Development-LID). Este estudo avaliou o uso desses dispositivos na bacia hidrográfica PD14 localizada na cidade de Teresina, Piauí, observando os efeitos de sua implementação para mitigação de escoamentos superficiais. O software PCSWMM foi utilizado para modelagem de LIDs do tipo telhado verde na área de estudo, considerando dois cenários diferentes de abrangência das LIDs modeladas. A partir da análise dos cenários modelados, observou-se a redução do volume total de água escoada variando entre 4,7 % e 12,13%, além da redução do pico de escoamento e atraso no início do deflúvio. Os resultados demonstraram a utilidade prática do uso de telhados verdes como medida eficaz de controle e mitigação do escoamento superficial em bacias urbanas.
