“…This choice allows us to keep the same parsimonious approach for the modeling of both the rural and urban basins. In facts, several studies suggest that the transfer function of an urban basin is not unique, the complexity of the different pathways leading to deviations from the Horton law in a certain extent (Berthier et al, 1999;Rodriguez et al, 2003Rodriguez et al, , 2005. Despite structural heterogeneities that are inherent in urban areas, the simplified model adopted here captures flow variations in both the river and sewer network.…”

Keywords:Urban hydrology Modeling Sewer catchment Case study s u m m a r y A parsimonious model of flow capable of simulating flow in natural/engineered catchments and at WWTP (Wastewater Treatment Plant) inlets was developed. The model considers three interacting, dynamic storages that account for transfer of water within the system. One storage describes the ''flashy'' response of impervious surfaces, another pervious areas and finally one storage describes subsurface flow. The sewerage pipe network is considered as an impervious surface and is thus included in the impervious surface storage. In addition, the model assumes that water discharged from several CSOs (combined sewer overflows) can be accounted for using a single, characteristic CSO. The model was calibrated on, and validated for, the Vidy Bay WWTP, which receives effluent from Lausanne, Switzerland (population about 200,000), as well as for an overlapping urban river basin. The results indicate that a relatively simple approach is suitable for predicting the responses of interacting engineered and natural hydrosystems.

“…In urban areas, peaks are mainly driven by direct runoff on impervious areas and sewer routing (Chocat and Cabane, 1999;Rodriguez et al, 2003). Overland flow on a 10 2 -10 3 m scale, according to Blöschl and Sivapalan (1995), corresponds to temporal scales smaller than one hour.…”

International audienceThe number of stormwater source control (SC) regulations adopted by local authorities is rapidly growing in many countries. We can expect that, in the near future, the hydrologic behavior of many urban and periurban catchments will reflect this diffusion. This paper discusses SC regulations through two complementary approaches: starting on three French case-studies, it analyzes how regulations are developed today and identifies a set of shortcuts in policy-making practices. Then, the hydrologic model of a periurban catchment in the Paris region is used to test the impacts that these regulations can produce if widely applied. The main finding is that inertia in policy-making, driving a singular focus on flow-rate based regulations, can produce negative impacts in the long-term. Further efforts on volume-based regulations are advocated, both in terms of research and policy-making. © 2012 Elsevier B.V. All rights reserved

“…Furthermore, urban areas can alter the transport of nutrients and other contaminants to surface water bodies [Interlandi and Crockett, 2003], which result in increased primary productivity [Smart et al, 1981] and impaired water quality. There have been many studies assessing the impact of agricultural activity on non\point contaminant sources [Puckett, 1995;Ekholm et al, 2000;Sharpley et al, 2001;Andraski and Bundy, 2003], but relatively few comprehensive studies characterizing the effects of urbanization on watershed scale hydraulic response and water quality [Rodriguez et al, 2003;Carle et al, 2005].…”

[1] Effective control of nonpoint source contaminants in runoff from urbanized watersheds requires knowledge about the locations of runoff source areas under a variety of conditions. Physical monitoring of spatially variant processes, such as runoff production form variable source areas, is time-consuming and expensive. Thus modeling the processes may provide a valuable cost-effective alternative. In this paper we adapt and validate a variable source model for an urban watershed to predict areas of the landscape prone to elevated soil moisture levels and saturation excess runoff. We modified the soil moisture distribution and routing (SMDR) model to simulate hydrologic processes in an urban upstate New York watershed by considering the impact of impervious surfaces, hydraulic control structures (detention basins), and land use on the water balance. In our model, infiltration excess runoff from impervious surfaces infiltrates in the surrounding soils. Simulated and observed streamflow agreed well, and more importantly, the distribution of soil moisture levels and overland flow throughout the watershed were well predicted. Removing urban features from the model resulted in substantially lower peak stormflows than observed, and the base and interflows increased accordingly. Both modeled and measured distributed results indicated that the more urbanized areas of the study site had both higher soil moistures and runoff losses due to shallower soils, greater upslope contributing areas, and a larger area of impervious surfaces generating runoff. The model results helped identify processes that describe how urbanization impacts integrated and distributed hydrology, which provides useful information for targeted water quality management.
