Dynamic Wave Simulation of Unsteady Open Channel and Surcharge Flows in Sewer Networks (saint-Venant Equations, Four-Point Implicit Finite Difference, Storm Sewer Drainage, Urban Hydrology)
Sewers are traditionally designed to operate under open-channel flow conditions. However, it is not uncommon that under high flows some or all of the pipes in a sewer network may change from open-channel flow to surcharge flow. For surcharge flow in a sewer there exist two techniques of …

Extracting curbside storm drain locations from street-level images
… or digital format. Access to these data for urban hydrologic and hydraulic modeling purposes may be limited by security protocols and/or the format in which the data may be available. The procedure described in this work uses a novel vision algorithm with Google Street View imagery to …

Quantitative precipitation forecasting (QPF) for surface water flood forecasting
… associated with meteorological forecasting and hydrology is a critical part of any integrated, interactive drainage system. The development of a dynamic surface water management system, based on the concept of Sustainable Urban Drainage System (SUDS) and coupled with a real-time extreme rainfall …

Using Geophysics and Terrestrial LiDAR to Assess Stormwater Parameters in Vacant Lots in Philadelphia
… and quality has become an important issue in urban hydrology. Impervious cover associated with urbanization increases surface runoff volumes and degrades the water quality of urban streams and rivers. Cities with combined stormwater and sewer lines such as Philadelphia, have been tasked with …

Observations and mechanistic modelling of the role of Aedes mosquitoes in dengue transmission in Singapore
… monsoons on the disease vectors; the impact of urban housing on spatial patterns of dengue transmission is explored; and mechanistic models are developed to simulate the seasonality of dengue occurrence in the city. The role of monsoons in shaping the seasonal pattern of dengue is investigated. …

Large-scale Process-based Urban Hydrological Modeling Framework
Urban flooding presents a significant global challenge, exacerbated by increasingly frequent extreme climate events and rapid urbanization. Mitigation efforts typically involve implementing various strategies to enhance stormwater storage and infiltration. However, the complexity of these …

The role of reliability in characterizing green stormwater infrastructure in urban areas
… to expand, the issues of flood control and urban water quality have risen to the forefront of modern sustainability challenges. Green infrastructure— the use of nature-based solutions to target, treat, and store stormwater at its source— has emerged as a possible solution. While green …

A framework for designing and optimizing green infrastructure network under uncertainty
Green infrastructure (GI) is becoming a common solution to mitigate stormwater-related problems. Despite wide acknowledgement of GI benefits, there is a lack of decision support tools that allow practitioners to interactively identify and evaluate the performance of small GI practices using …

Precipitation Estimation Methods in Continuous, Distributed Urban Hydrologic Modeling
… in hydrological modeling, particularly in small, urban watersheds which respond rapidly to precipitation and can experience significant spatial variability in rainfall fields. Few studies have compared QPE methods in small, urban watersheds, and studies which have examined this topic only compared …

Restoring the Lost Rivers of Washington: Can a city's hydrologic past inform its future?
… older U.S. cities, suffers the woes of rapid urbanization and aging infrastructure. The city's combined sewer and stormwater system dumps millions of gallons of raw sewage into the Anacostia and Potomac Rivers over 70 times annually during significant rain events. While many groups, both …

MONITORING STORMWATER INFILTRATION IN A VACANT LOT COMPARING TIME-LAPSE ELECTROMAGNETIC INDUCTION AND ELECTRICAL RESISTIVITY TOMOGRAPHY
Vacant lots in cities and surrounding urban areas can potentially be used for stormwater management because they are pervious. However, the extent to which vacant lots provide pervious cover to increase infiltration and reduce stormflow is poorly understood. The goal of this study was to develop …

Improved understanding and prediction of the hydrologic response of highly urbanized catchments through development of the Illinois urban hydrologic model (IUHM)
What happens to the rain in highly urbanized catchments? That is the question that urban hydrologists must ask themselves when trying to integrate the hydrologic and hydraulic processes that affect the hydrologic response of urban catchments. The Illinois Urban Hydrologic Model (IUHM) has been …

Influence of stormwater control measures on watershed hydrology and biogeochemical cycling
<p>Urban development replaces vegetation with impervious surfaces and natural drainage channels with pipe networks that quicken flow paths and alter hydrologic regimes. Additionally, the import of food, application of fertilizer to lawns and gardens, and heightened atmospheric deposition increases …

IMPACTS OF URBAN DEVELOPMENT PATTERN ON RUNOFF PEAK FLOWS AND STREAMFLOW FLASHINESS OF PERI-URBAN CATCHMENTS: ASSESSING THE PERFORMANCE OF PHYSICAL AND DATA-DRIVEN MODELS FOR REAL-TIME ENSEMBLE FLOOD FORECASTING
<p>Urban growth is a global phenomenon, and the associated impacts on hydrology from land development are expected to increase, especially in peri-urban catchments, which are newly developing catchments in proximity of growing cities. In northern climates, hydrologic response of peri-urban …

Aqua.Street.Scapes: Interpreting Natural Hydrologic Processes while Enhancing the Urban Streetscape
This project proposes a new urban aquifer strategy that utilizes stormwater to create a cascading plaza and an improved 'great street' in Washington DC. A system of urban aquifers is developed beneath the surface of the street, perched atop the compacted, impermeable soils below. This set of …
