Matt Pitt of Cranfield University has a deep interest in modelling hydraulic data and is part-way through a fascinating PhD project centred on the ways in which various tillage regimes affect the long-term properties of soil. “My research aims to assess if non-inversion tillage practices improve water transport in soil during and near saturation – where percolation leads to ...
These programs provide data to assess the distribution, concentrations and types of PFAS attributed to a range of sources within a region, such as a catchment, urban area or jurisdiction. The programs also incorporate reference site characterization. ...
With rapid urbanization, inundation-induced property losses have become more and more severe. Urban inundation modeling is an effective way to reduce these losses. This paper introduces a simplified urban stormwater inundation simulation model based on the United States Environmental Protection Agency Storm Water Management Model (SWMM) and a ...
Abstract Accurate prediction of flood extents in urban catchments is extremely difficult without having a 1d/2d integrated modeling approach. ...

Hydrology There are over 360 hydrologic nodes in the model. Three catchments potentially drain to a given node and are represented by the fish streets, mammal streets, and the residential areas. ...

The initial model build for this study included only 1D elements. The catchment was divided into 177 sub-catchments, runoff from these catchments was described using the Runoff method and the GreenAmpt infiltration method. ...

It was a unique opportunity to prove a computer model with data from an extreme event. We also wished to identify any difficulties modeling the event, improve the computer model and develop an efficient workflow. ...

Besides the outlined evaluation of the sediment transport behaviour of the pressure main, the collected data were used in the project to calibrate a sewer system model, including a water quality model for the catchment area, and as a contribution towards an early physically based sediment transport modelling in InfoWorks CS. ...
This paper describes Greater Copenhagen Utility's role in planning, coordinating and implementing Copenhagen's Climate Change Adaptation Plan and Cloudburst management strategy. Detailed hydraulic modelling of the seven catchments in the city resulted in the preparation of a cloudburst management plan with more than 350 interventions, at a budget of EUR 1.3 ...
Event-based rainfall–runoff models are useful tools for hydrologic design. Of the many loss models, the ‘initial loss-continuing loss’ model is widely adopted in practice. Some of the key limitations with these types of loss models include the arbitrary selection of initial moisture (IM) conditions and lack of physically ...
Over 80% of the new data cases were correctly classified by the trained DFA model. When applied to data cases from a mixed land-use catchment and downstream, the DFA model showed the greater impact of urban areas and rural areas respectively in the earlier and later parts of a storm event. ...
To assess the effect of three grid cell properties (size, mean slope of the surface and distance between centre of grid and observation well) on groundwater models' performances, a tropical karst catchment characterized by monsoonal season in Rote Island, Indonesia was selected. Here, MODFLOW was used to develop models with five different ...
Sewer level monitoring is undertaken in real-time and intelligent raingauges (smart sensors) combine with radio telemetry to inform a computer based catchment-wide water model. This decision support system provides advance notice for staff at the Eastney pumping station that diverts large quantities of water to storage tanks during periods of heavy rain. ...
Conceptual rainfall–runoff models are widely used to understand the hydrologic responses of catchments of interest. ...
Many rainfall–runoff (RR) models are available in the scientific literature. Selecting the best structure and parameterization for a model is not straightforward and depends on a broad number of factors, including climatic conditions, catchment characteristics, temporal/spatial resolution and model objectives. ...
The significance of spatial variability of rainfall on runoff is explored as a function of catchment scale and type, and antecedent conditions via the continuous time, semi-distributed probability distributed model (PDM) hydrological model applied to the Upper Lee catchment, UK. The impact of catchment scale ...
The standardized precipitation index (SPI) and standardized runoff index (SRI) are computed for several gauge stations in Panjiakou Reservoir catchment of Luanhe Basin, a drought prone region of North China. Based on the SPI and SRI time series, two different models, a weighted Markov chain model and a Volterra adaptive filter ...
The extreme cycles of flood and drought in the Poyang Lake catchment (China) place immense pressure on the region's water users and ecosystems. This study examines potential impacts of future climate change in the Poyang Lake catchment using the popular regional climate model, COSMO-CLM, and a distributed hydrological model, ...
The Storm Water Management Model (SWMM) has been an effective tool for simulating floods in urban areas, but has been seldom applied for river systems. In this study, a geographic information system (GIS)-based SWMM model was developed to authenticate the model's viability as a streamflow simulator for modeling floods in the Brahmani river delta. The model was set up using a Shuttle Radar ...
This issue has been investigated by coupling a wavelet artificial neural network (WA-ANN) precipitation model with a soil and water assessment tool (SWAT) model to assess the export of nonpoint source pollutants from the Liao River source area. The calibration and validation of these models are outlined. The WA-ANN models and the ...
