Ocean HDPE Liner (400 micron) was selected to act as a barrier within the pavement and drainage system, delivering enhanced subgrade moisture control, drainage efficiency, and containment performance under extreme dynamic loads, fuel exposure, and environmental variation. ...
For water companies in England and Wales, the primary takeaway is that enforcement action will not be pursued provided strict conditions regarding reporting and long-term remediation are met.Key compliance detailsThe EA guidance is valid now, and expires on 31 March 2030All infiltration reduction plans (IRPs), and measures must be included in draft Drainage & Wastewater ...
Sector MR-10 is located next to the dunes, which form a natural barrier to water run-off coming from the mountains (on the West) to the sea (on the East). The drainage system planned for this development aims to replicate the natural hydrologic cycle, using Sustainable Urban Drainage Systems (SuDS), knowned as well as LIDs or BMPs, through the development, and ...

Inlet efficiency is a requirement for characterizing the flow transfers between surface and sewer flow during rain events. The dual drainage approach is based on the joint analysis of both upper and lower drainage levels, and the flow transfer is one of the relevant elements to define properly this joint behaviour. ...
The model was used to examine the hydraulic performance of a number of groundwater drainage scenarios. A cost analysis was carried out and a specific annual cost function was introduced. Moreover, a multi–criteria analysis was conducted to select the most relevant drainage scenario. The analysis shows that the ...
This study employs a data set of 23 river flow time series from Sefidrood Drainage Basin, Iran, to examine regional hydrological drought based on the low flow index 7Q10. Hierarchical agglomerative cluster analysis was used to divide the 23 gauging stations into two homogeneous drought regions based on the similarity of the binary drought series. 7Q10 was ...
Metropolitan Colliery being one of such mines, has experienced difficulties in reducing gas content within the available drainage lead time; as the coal seam would not drain even with additional drainage boreholes. A research study using coal permeability testing and microstructure analysis was carried out to investigate the hard–to–drain ...

The central objective of this project has been the full study of Tunisia's drainage tunnels. The inventory, analysis and heritage evaluation of Tunisia's ‘qanats’ have been possible through the application of a particular methodology during four annual sessions of fieldwork and analysis in the geographic information ...
There is increasing awareness about uncertainties in the modelling of urban drainage systems and, as such, many new methods for uncertainty analyses have been developed. ...
Urban drainage systems are frequently analysed using hydraulic modelling software packages such as InfoWorks CS or MIKE-Urban. The use of such modelling tools allows the evaluation of sewer capacity and the likelihood and impact of pluvial flood events. Models can also be used to plan major investments such as increasing storage capacity or the implementation of sustainable urban drainage ...
Flood analysis of urban drainage systems plays a crucial role for flood risk management in urban areas. ...
The services undertaken by Hydro-Logic included site reconnaissance, hydrological analysis, drainage design and preparation of an FRA. The shallow gradient of the existing site meant that there was limited runoff from the site and localised areas that were waterlogged. The hydrological analysis required an assessment of the likely increase in ...
As the pressure gradient was increased, both the altitude dependence and non–uniformity of contact angles decreased, and the mean curvature of the drainage and imbibition interfaces increased and decreased, respectively. ...
In continuing these efforts, the City initiated the City-Wide Storm System Master Plan (the Study) in 2002 to evaluate the impact of current and future development on the existing storm drainage system. The Study Area, illustrated on Figure 1, encompasses 27 sq.km (11 sq.mi) of land within the City’s boundaries, as well as external lands that drain into the City’s ...

In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty ...
The second model approach consists of the simplified reservoir model. The analysis used a parsimonious bespoke model developed in previous studies. For the uncertainty analysis, the Generalised Likelihood Uncertainty Estimation (GLUE) procedure was used. ...
The objectives of this study are to introduce a new urban flood modelling procedure that is able to reflect system interactions with hydrology, verify that the new procedure operates well, and underline the importance of considering the complete water cycle in urban flood analysis. A physically-based and distributed hydrological model was linked to a drainage ...
The objective of this case-study analysis was to investigate how site-specific decisions can be improved by transforming a long-term multiple-crop yield-map dataset into profit maps that contain economic thresholds representing profitability zones. ...
