The relative impact of urbanisation (urban sprawl), climate change (rainfall and evapotranspiration) and stormwater disconnection strategies (implementation of green infrastructure (GI)) on a peri-urban stream in the western suburbs of Lyon, France, was investigated using a distributed, physically based model (J2000P). Results showed that ambitious catchment-scale implementation of GI has the potential to mitigate some hydrological effects of urbanisation, especially a drastic reduction of combined sewer overflows. However, GI did not have a large impact on the stream flow regime, especially in the context of climate change, as the stream is dominated by non-urban contributions. Spatially distributed models have the capacity to inform river managers about the extent of implementation of GI needed to achieve given management goals and highlight some limitations of disconnection strategies. Indeed, while GI improved the resilience of sewer networks to global change, it was not sufficient to compensate for the effects of climate change on streamflow.

After becoming a capital city of Chhattisgarh state in 2001, the city Raipur in India has been rapidly growing in terms of population as well as areal expansion. With the process of urbanization and alteration of the natural drainage system, the existing stormwater drainage system became insufficient to drain the area, resulting in a higher risk of flooding. In this study, the effect of urbanization on the runoff generation and peak flow and their impact on the stormwater drainage system have been investigated. Digital land-use data from aerial photograph, satellite images and Differential Global Positioning System (DGPS) survey were used to detect and analyse the shift in land-uses since the evolution of Raipur city. For the same periods, total generated runoff and peak flow as well as flood-prone locations along the drainage network have been simulated. The results showed an increase in build-up area of 99.2, 22.0 and 0.6%, respectively. Agricultural areas increased by 210.8, 157.5 and 0.6%, respectively. Forests and tree covers almost completely disappeared. The higher share of build-up areas led to an increase in total runoff generation and peak flows. The maximum runoff increased by 87.92 x 10(6) L and maximum peak flows changed from 11.03 to 14.09 m(3)/s. The results show significant increase in runoff and peak discharge in the study area due to human intervention, since Raipur city started altering natural drainage system. Moreover, the model can be used for future flood forecasting in Raipur city, and the results from this study can be utilized to develop flood mitigation measured as best management practices in Raipur.

Comparative study of conceptual versus distributed hydrologic modelling to evaluate the impact of climate change on future runoff in unregulated catchments

The application of two distinctively different hydrologic models, (conceptual-HBV) and (distributed-BTOPMC), was compared to simulate the future runoff across three unregulated catchments of the Australian Hydrologic Reference Stations (HRSs), namely Harvey catchment in WA, and Beardy and Goulburn catchments in NSW. These catchments have experienced significant runoff reduction during the last decades due to climate change and human activities. The Budyko-elasticity method was employed to assign the influences of human activities and climate change on runoff variations. After estimating the contribution of climate change in runoff reduction from the past runoff regime, the downscaled future climate signals from a multi-model ensemble of eight global climate models (GCMs) of the Coupled Model Inter-comparison Project phase-5 (CMIP5) under the Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 scenarios were used to simulate the future daily runoff at the three HRSs for the mid-(2046-2065) and late-(2080-2099) 21st-century. Results show that the conceptual model performs better than the distributed model in capturing the observed streamflow across the three contributing catchments. The performance of the models was relatively compatible in the overall direction of future streamflow change, regardless of the magnitude, and incompatible regarding the change in the direction of high and low flows for both future climate scenarios. Both models predicted a decline in wet and dry season's streamflow across the three catchments.

Blue and Green Infrastructures (B&GI) are nature-based solutions considered as particularly efficient to reduce the potential impact of new and existing developments with respect to stormwater issues. In order to assess their performance at some large scales compatible with urban projects, adapted distributed rainfall-runoff models are required. The latest advancements of the Multi-Hydro platform have made possible the representation of such B &GI. Applied in a virtual new urban development project located in the Paris region, Multi-Hydro has been used to simulate the impact of B&GI implementation, and their ability to fulfil regulation rules authorizing the connexion to the sewer network. The results show that a combination of several B&GI, if they are widely implemented, could represent an efficient tool to meet regulations at the parcel scale, as they can reduce runoff volume about 90%.

Testing the Efficiency of Parameter Disaggregation for distributed Rainfall-Runoff modelling

A variety of hydrological models is currently available. Many of those employ physically based formulations to account for the complexity and spatial heterogeneity of natural processes. In turn, they require a substantial amount of spatial data, which may not always be available at sufficient quality. Recently, a top-down approach for distributed rainfall-runoff modelling has been developed, which aims at combining accuracy and simplicity. Essentially, a distributed model with uniform model parameters (base model) is derived from a calibrated lumped conceptual model. Subsequently, selected parameters are disaggregated based on links with the available spatially variable catchment properties. The disaggregation concept is now adjusted to better account for non-linearities and extended to incorporate more model parameters (and, thus, larger catchment heterogeneity). The modelling approach is tested for a catchment including several flow gauging stations. The disaggregated model is shown to outperform the base model with respect to internal catchment dynamics, while performing similarly at the catchment outlet. Moreover, it manages to bridge on average 44% of the Nash-Sutcliffe efficiency difference between the base model and the lumped models calibrated for the internal gauging stations. Nevertheless, the aforementioned improvement is not necessarily sufficient for reliable model results.

Global and continental scale hydrological reanalysis datasets receive growing attention due to their increasing number of applications, ranging from water resources management, climate change studies, water related hazards and policy support. Until recently, their use was mostly limited to qualitative assessments, due to their coarse spatial and temporal resolution, large uncertainty and bias in the model output, and limited extent of the dataset in space and time. This research reports on the setup of a gridded hydrological model with quasi-global coverage, able to reproduce a seamless 39-year streamflow simulation in all world's medium to large river basins. The model was calibrated at 1226 river sections with a total drainage area of 51 million km(2) within 66 countries, using ECMWF's latest atmospheric reanalysis ERAS. A performance assessment revealed large improvements in reproducing past discharge observations, in comparison to the calibration used in the current operational setup of the hydrological model as part of the Copernicus - Global Flood Awareness System (GloFAS, ***), with median scores of Kling-Gupta Efficiency KGE = 0.67 and correlation r = 0.8. The simulation bias was also dramatically reduced and narrowed around zero, with more than 60% of stations showing percent bias within +/- 20%. Pronounced regional differences in the simulation results remain, pointing out the need for detailed investigation of the hydrological processes in specific regions, including parts of Africa and South Asia. In addition, observed discharges with high data quality is key to achieving skillful model output. The new calibrated model will become part of the operational runs of GloFAS in the next system release foreseen for Spring 2020, together with a near real time extension of the streamflow reanalysis.

Thermal-hydraulic considerations in urban drainage networks are essential to utilise available heat capacities from waste- and stormwater. However, available models are either too detailed or too coarse;fully coupled thermal-hydrodynamic modelling tools are lacking. To predict efficiently water-energy dynamics across an entire urban drainage network, we suggest the SWMM-HEAT model, which extends the EPA-StormWater Management Model with a heat-balance component. This enables conducting more advanced thermal-hydrodynamic simulation at full network scale than currently possible. We demonstrate the usefulness of the approach by predicting temperature dynamics in two independent real-world cases under dry weather conditions. We furthermore screen the sensitivity of the model parameters to guide the choice of suitable parameters in future studies. Comparison with measurements suggest that the model predicts temperature dynamics adequately, with RSR values ranging between 0.71 and 1.1. The results of our study show that modelled in-sewer wastewater temperatures are particularly sensitive to soil and headspace temperature, and headspace humidity. Simulation runs are generally fast;a five-day period simulation at high temporal resolution of a network with 415 nodes during dry weather was completed in a few minutes. Future work should assess the performance of the model for different applications and perform a more comprehensive sensitivity analysis under more scenarios. To facilitate the efficient estimation of available heat budgets in sewer networks and the integration into urban planning, the SWMM-HEAT code is made publicly available.

In this paper, a method for the dynamic modification of tooth width is used to optimize the problem of uneven loading of helical gears. Considering the meshing error caused by gear manufacturing, installation, time-varying meshing stiffness, clearance, and shaft bending, the distributed meshing transverse-torsion-pendulum nonlinear dynamic model of a helical gear pair is established. A method to modify the tooth width of the helical gear pair is proposed to optimize the uniform load characteristics of the tooth surface. Through the research of dynamic tooth width modification, the optimal modification parameters are obtained so that the dynamic load distribution of the tooth surface is uniform and the load distribution centre is close to the centre of the tooth surface, which reduces the swing phenomenon. During experimental testing, the swing vibration response of the modified gear is reduced by a maximum of 26.15%, the dynamic load coefficient is reduced by a maximum of 20.84%, and the stress distribution on the tooth surface is uniform.

From single fields to river basins: Identification of critical source areas for erosion and phosphorus losses at high resolution

Concentrations of phosphorus (P), the main limiting nutrient in freshwater ecosystems, need to be reduced, but this is difficult due to high spatial and temporal variations and limited resources. Reliable targeting of critical source areas, such as erosion-prone fields and parts of fields, is necessary to improve the cost efficiency of mitigation measures. We used high-resolution (2 m x 2 m) distributed modelling to calculate erosion risk for a large area (202 279 km(2)) covering > 90% of Swedish arable land. Comparison of model results with independent farmers' observations in a pilot catchment showed high spatial agreement. The modelled worst case scenario produced reasonable quantitative results comparable to measured 90th percentile values of suspended sediment (SS) loads at both field and small catchment scale (R-2 = 0.81, p < 0.001). Overall, loads of SS, especially during extreme episodes, strongly governed losses of unreactive P and total P at both field and catchment scale.

The Canadian prairies are dominated by numerous depressions, which can modify the lateral transfer of water to prairie streams. Few studies were conducted to simulate the pothole dynamics using their actual spatial distributions. This study proposes a computationally efficient Prairie Region Inundation MApping (PRIMA) model as a hydrologic routing model, for a more accurate and comprehensive storage dynamics simulation and inundation mapping in the prairies. PRIMA shows potential for simulating the potholes' extents when comparing its results with remote sensing data of pothole areas with an accuracy of 85% averaged over two prairie basins in Saskatchewan, Canada. PRIMA is three similar to eight times as computationally efficient as the recently developed Wetland DEM Ponding Model (WDPM). Due to its computational efficiency and ability to provide a good simulation of inundation extents, PRIMA shows strengths as a possible tool for pothole inundation mapping and storage dynamics simulations.
