  • Characterization of the hydraulic performance of a gully under drainage conditions

    During rainfall events with low return periods (1–20 years) the drainage system can provide some degree of protection to urban areas. The system design is based not only on good hydraulic performance of the surface and the sewer network but also on their linking elements. Although the linking elements are of utmost importance as they allow the exchange of flow between the surface and the ...

  • Gully and overland modeling during extreme events

    Consultants JBA have been involved in modeling gully and overland flows during extreme events as part of the Interreg IIIB NWE (North West Europe) ’urban water’ project, which is being undertaken by Renfrewshire Council in Scotland. Research for this project was commissioned following flooding in 1994 and 1999. The project takes a strategic look at urban flood risk management on a large scale, ...

  • An experimental and computational investigation of performance of the Green Gully for reusing stormwater

    A new stormwater quality improvement device called ‘Green Gully’ has been designed and developed in this study with the aim of reusing stormwater for irrigating trees and other plants. The main purpose of the Green Gully is to collect road runoff/stormwater, make it suitable for irrigation and provide an automated network system for watering roadside plants and irrigational areas. This paper ...

  • Evaluation of Changes in Water Quality and Urban Runoff in the Buck Gully Watershed, California, through the use of Weatherbased Irrigation Control

    ABSTRACT The Buck Gully watershed is located in the Newport Coast area of California. Buck Gully is located in a coastal canyon which drains into an area designated as a State Water Quality Protection Area (formerly Area of Special Biological Significance). The adjacent coastal land is designated as a Critical Coastal Area. The upper portion of the watershed is in the Newport Coast area, and ...

  • The role of settling velocity formulation in the determination of gully pot trapping efficiency: comparison between analytical and experimental data

    Roadside gully pots are the connecting points between surface runoff and the underground drainage network; therefore they can be considered as the most superficial component of urban drainage systems. Gully pots are supposed to trap particulate matter washed off the catchment surface, but also to collect and convey stormwater into the network. The continuous accumulation of particulate matter ...

  • Responses of streamflow and sediment load to climate change and human activity in the Upper Yellow River, China: a case of the Ten Great Gullies Basin

    Soil erosion and land desertification are the most serious environmental problems globally. This study investigated the changes in streamflow and sediment load from 1964 to 2012 in the Ten Great Gullies area of the Upper Yellow River. Tests for gradual trends (Mann–Kendall test) and abrupt changes (Pettitt test) identify that significant declines in streamflow and sediment load occurred ...

  • Experimental and numerical investigation of interactions between above and below ground drainage systems

    This paper presents the results of the experimental and numerical investigation of interactions between surface flood flow in urban areas and the flow in below ground drainage systems (sewer pipes and manholes). An experimental rig has been set up at the Water Engineering Laboratory at the University of Sheffield. It consists of a full scale gully structure with inlet grating, which connects the ...

  • The efficiency of asset management strategies to reduce urban flood risk

    In this study, three asset management strategies were compared with respect to their efficiency to reduce flood risk. Data from call centres at two municipalities were used to quantify urban flood risks associated with three causes of urban flooding: gully pot blockage, sewer pipe blockage and sewer overloading. The efficiency of three flood reduction strategies was assessed based on their effect ...

  • ArmorMax® is Solution for Alberta, Canada Transportation case study

    Background In Alberta Canada. Alberta Transportation identified two ditches. H614:02 north ditch and H894:04 east ditch that had experienced severe erosion. Both ditches service drainage needs for adjacent farmland that comprises hundreds of acres of land. The bed slopes on the two ditches averaged approximately 7%, which enabled the silty soils to easily erode even during modest storm ...

  • Overland flow computations in urban and industrial catchments from direct precipitation data using a two-dimensional shallow water model

    This paper presents the experimental validation and the application to a real industrial catchment of a two-dimensional depth-averaged shallow water model used for the computation of rainfall-runoff transformation from direct precipitation data. Instead of using the common approach in flood inundation modelling, which consists in computing the water depth and velocity fields given the water ...

  • Upgrading a municipal WWTP using AGAR® technology

    In view of EU directives for effluent discharge, it was required to upgrade the local sewage plant in the town of Marines, Valencia (Spain). The technology chosen for the project was AGAR® (Attached Growth Airlift Rector) of AqWise - Wise Water Technologies Ltd. La Entidad Pública de Saneamiento de Aguas Residuales (EPSAR) has promoted the implementation of the AGAR® system in the Valencian ...

  • Modeling overland flows in InfoWorks CS

    A new tool within InfoWorks CS v7.5 enables the presentation of flood depths within the bounds of a polygon, otherwise known as a flood compartment. The flood level can be extended throughout the boundaries of the compartment, allowing it to be matched against a ground model to calculate flood depth. The new tool does not alter the way in which flood calculations are undertaken, it is instead a ...

  • Past and future perspectives upon landscape instability in Cumbria, northwest England

    Abstract  Geomorphic and lacustrine evidence is used to identify phases of landscape instability in Cumbria, northwest England, British Isles. The temporal and spatial pattern of erosion is used alongside palaeovegetation data from across the region to elucidate the causes of landscape instability in the late Holocene. The lines of evidence include changes in sediment accumulation rate and ...
