Research on improving an overland flow model is presented for urban pluvial flooding under the dual-drainage concept where sewer dynamically interacts with flow. This occurs during heavy storms when system surcharged. The becomes pressurised and increases by additional volume flowing out from sewer. To represent realistically, a new methodology was developed to automatically create network which can interact drainage system. Use made of high-resolution, accurate Digital Elevation Model data...
Image velocimetry has proven to be a promising technique for monitoring river flows using remotely operated platforms such as Unmanned Aerial Systems (UAS). However, the application of various image algorithms not been extensively assessed. Therefore, sensitivity analysis conducted on five different including Large Scale Particle Velocimetry (LSPIV), Large-Scale Tracking (LSPTV), Kanade–Lucas Tomasi (KLT-IV or KLT), Optical (OTV) and Surface Structure (SSIV), during low flow conditions...
The new simulation model, named SIPSON, based on the Preissmann finite difference method and conjugate gradient method, is presented in paper. This model simulates conditions when hydraulic capacity of a sewer system exceeded, pipe flow pressurized, water flows out from piped to streets, inlets cannot capture all runoff. In mathematical buried structures pipelines, together with surface channels, make horizontally vertically looped network involving complex interaction flows. this paper,...
The paper presents the development of field urban drainage modelling known as dual - an approach to rainfaill runoff simulation in which numerical model takes into account not only flow through sewer system, but also on surface. steps are described, and necessary data, assumptions used operations be performed using GIS discussed. simultaneously handles full dynamic equations system simplified surface flow. excess water (due limited capacity inlets or hydraulic head reaching ground level) is...
Previous experimental research on the effects of debris pier scour has focused primarily circular and rectangular piers with present just under flow free surface. Debris-induced around sharp-nose piers, which are typical masonry bridge effect elevation have seldom been studied before. This paper aims to fill this knowledge gap. It presents results from flume experiments investigating a shallow conditions angle attack relative being zero. Uniform sand is used as bed material. Debris modeled...

<p>Image velocimetry (IV) is a remote technique which calculates surface flow velocities of rivers (or fluids) via range cross-correlation and tracking algorithms. IV can be implemented camera sensors mounted on tri-pods, or Unmanned Aerial Systems (UAS). has proven powerful for monitoring river flows during flood conditions, whereby traditional in-situ techniques would unsafe to deploy. However, little research focussed upon the application such low conditions. The...
Lead time between rainfall prediction results and flood obtained by hydraulic simulations is one of the crucial factors in implementation real-time forecasting systems. Therefore, simulation times must be as short possible, with sufficient spatial temporal distribution modelling accuracy. One ways to reduce required run model increasing computational speed simplifying networks. This simplification can conducted removing changing some secondary elements using network techniques. The emphasis...
This paper presents the developments towards next generation of overland flow modelling urban pluvial flooding. Using a detailed analysis Digital Elevation Model (DEM) developed GIS tools can automatically generate surface drainage networks which consist temporary ponds (floodable areas) and paths link them with underground network through inlets. For different commercially-available Rainfall–Runoff simulation models, tool will needed to model runoff flooding accurately. In this emphasis is...
The number of automated measuring and reporting systems used in water distribution sewer is dramatically increasing and, as a consequence, so the volume data acquired. Since real-time likely to contain certain amount anomalous values acquisition equipment not perfect, it essential equip SCADA (Supervisory Control Data Acquisition) system with automatic procedures that can detect related problems assist user monitoring managing incoming data. A different anomaly detection techniques methods...
Sectorization of a water distribution network (WDN) into district metered areas (DMAs) is proven solution for proactive leakage control. Traditionally, WDN sectorization conducted by local experts using trial-and-error approach, often resulting in the identification arbitrary solutions. Some recently published methods try to improve automating process, especially optimization. Various criteria, constraints, and limitations are introduced, which fail consider issues faced poorly managed WDNs...
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow all regimes, is an approach that enables efficient numerical simulation of supercritical transcritical flows pipe/channel systems. However, as well certain errors within a single channel due incomplete equations, this technique also may introduce unwanted effects propagating across network both upstream downstream directions. These include:...
Advances in sensor technology and the possibility of automated long distance data transmission have made continuous measurements preferable way monitoring urban drainage processes. Usually, collected to be processed by an expert order detect mark wrong data, remove them replace with interpolated data. In general, first step detecting wrong, anomaly is called quality assessment or validation. Data validation consists three parts: preparation, scores generation interpretation. This paper will...

Abstract In water distribution network (WDN) modelling, nodal demand is the sum of flows taken by users associated with a computational node. User demands are not fixed in time; rather they stochastic. Hence, model parameter high uncertainty, which propagated throughout WDN model, thus also rendering output values (node pressures and pipe discharges) uncertain. Total inflow into can be accurately measured using flow meters. This paper investigates how knowledge system used as constraint...
To optimize the design of a water distribution network (WDN), large number possible solutions need to be examined; hence computation efficiency is an important issue. accelerate computation, one can use more powerful computers, parallel computing systems with adapted hydraulic solvers, hybrid algorithms, efficient methods or any combination these techniques. This paper explores possibility speed up optimization using variations ΔQ method solve hydraulics. First, was used inside evaluation...
Different methods have been developed in the past to formulate and solve steady-state hydraulics of a water distribution system (WDS). The most widely used method nowadays is probably global gradient algorithm (GGA). loop-flow (also known as ΔQ method) represents viable alternative GGA, especially when combined with suitably preprocessed network data. main advantage over GGA smaller number unknowns for, which coming from fact that real WDSs typically far less loops than nodes. A new...
Conventional urban drainage models deal with rainfall-runoff analysis under the effects of local storms. Additionally, areas are also vulnerable to floods caused by surface flows anthropogenic origin (main bursts for example) which need be modelled. In most cases commercially available relatively reliable when dealing free and pipe flow separately. However, system becomes surcharged, reliability strongly dependent on quality modelling interactions between underground sub-systems. At present,...
