Technical Seminar:

Coastal Challenges to Flood Management in times of Climate Change

Organised by

HKIE EVD, CVD

Civil and Environmental Engineering Dept of the HK Polytechnic University

BSOMES

IAHR-HK

Date:         December 19, 2018 (Wednesday)

Time:        18:30 pm - 20:00 pm

Venue:      Room Y302, Block Y, The HK Polytechnic University

Programme Highlights:

Super-Typhoon Mangkhut 2018 caused high storm surges resulting in serious flooding in many low-lying coastal areas in Hong Kong. This reminds us of the inadequacy of our flood management infrastructure which has been well developed mainly for inland areas subject to rainfall induced floods. At the same time, with indisputable Climate Change, the mean sea levels are rising and storm surges will also be increased by more frequent Super-Typhoons due to increasingly warm Pacific Ocean temperatures. This seminar is to share the Speaker’s insights into the coastal challenges to flood management in times of Climate Changes. He will address coastal flood mitigation measures including emergency evacuation based on real-time sea level forecasting (by combining storm surge and astronomical tide predictions), coastal polders, storm surge barriers and floating structures. The last two measures are new to Hong Kong.

Lab Visit and BBQ Gathering (5th November 2016 Saturday)

The design and management of UWSS (Smart Urban Water Supply Systems) is currently limited by the range and resolution of data collection in the relatively inaccessible buried pipelines. Current methods fail to provide the diagnostic resolution needed for many practical problems. The Project Smart UWSS propose a comprehensive theme-based research program involving theoretical, laboratory and field studies to develop a new diagnostic paradigm for water supply network monitoring and fault detection. The findings will enable timely detection of UWSS system defects and proactive mitigation measures (Project website: http://smartuws.ust.hk/). We will be able to have a close look at their innovative system and new equipment under the guidance of the project members.

Statistically Based Approaches to Understanding Fluvial Bedload Sediment Transport

 

by

 

Professor Simon Tait
Department of Civil and Structural Engineering
?/span>The University of Sheffield, United Kingdom

 

Date:      September 22, 2016 (Thursday)

Time:     5:00 p.m. - 6:00 p.m.

Venue:   Room 6-12B, Haking Wong Building

               The University of Hong Kong        

 

ABSTRACT

The transport of bedload sediments in rivers is recognized to exhibit a casual and intermittent nature. This seminar will describe the results from a number of studies in which statistically based approaches have been used to understand and then develop models of the physical components of fluvial bedload transport.

Bedload transport can be split into three main mechanisms: entrainment, transport and deposition. Detailed laboratory studies have been undertaken to examine the stochastic behaviour of the entrainment and transport phase of bedload.?

 

In the first group of experiments incipient motion is considered a random process that requires an appropriate stochastic description. Laboratory tests examined the effect of near-bed turbulence on grain entrainment and theoretical treatments included the variation in stability of randomly configured bed particles due to local surface heterogeneity completed the investigation. Both laboratory and theoretical approaches were combined into a probabilistic framework based on the original Grass theory. The analysis provides additional insight, in terms of grain dynamics, into the physical aspects that determine the initiation of bedload movement. These insights suggest that, although the hydrodynamic forces acting on the sediment bed and the resistance to motion of the bed particles are two interdependent aspects of a unique compound process, these random mechanisms can be accounted for separately if the conditional independence hypothesis holds.


Detailed grain transport measurements were also used to develop a stochastic description of particle step lengths as a function of shear stress and particle size distribution.?The statistical descriptions of step length suggested that the bedload transport showed strong diffusive behaviour. A modified Exner approach is being developed and implemented to simulate the stochasticity of the diffusive behaviour of the bedload. This approach will attempt to reflect the stochastic behaviour observed in the laboratory and allows examination of the parameters that control such behaviour. The resulting simulated gran advection and diffusion were confirmed by experimental testing in both linear and annular flumes.

TOPIC: Many of the world’s large ecosystems are severely stressed due to population growth, water quality and quantity problems, vulnerability to flood and drought, and the loss of native species and cultural resources. Consequences of climate change further increase uncertainties about the future. These major societal challenges must be addressed through innovations in governance, policy, and ways of implementing management strategies. Science plays a critical role in helping define possible alternative futures that could be achieved and the possible consequences to economic development, quality of life, and sustainability of ecosystem services. Science has advanced rapidly during the past decade with the emergence of science communities coalescing around ‘Grand Challenges?and the maturation of how these communities function has resulted in large interdisciplinary research networks. This trend has been complemented by major advances in sensor technologies, data synthesis and mining to accelerate knowledge discovery. These factors combine to allow scientific debate to occur in a more open and transparent manner. The availability of information and improved communication of scientific and engineering issues is raising the level of dialogue at the science-policy interface. However, severe challenges persist since scientific discovery does not occur on the same timeframe as management actions, policy decisions or at the pace sometimes expected by elected officials. Common challenges include the need to make decisions in the face of considerable uncertainty, ensuring research results are actionable and preventing science being used by special interests to delay or obsfucate decisions.

 

These challenges are explored in the context of the California Bay-Delta system. California transfers water from the wetter northern part of the state to the drier southern part of the state through the Central Valley Project since 1940 and this was supplemented by the State Water Project in 1973. The scale of these activities is remarkable: approximately two thirds of the population of Californians rely on water from the Delta, these waters also irrigate up to 45% of the fruits & vegetables produced in the US, and about 80% of California's commercial fishery species live in or migrate through the Bay-Delta. This Delta region is a hotspot for biodiversity that provides habitat for 700 species, but is also a hotspot for the loss of biodiversity ?more than 25 species currently are listed by the Endangered Species Act. These conflicts have been compounded as California is currently experiencing one of the most severe droughts in recorded history. Understanding the decline of the fragile ecosystem of

the Bay-Delta system and the potential consequences to economic growth if water transfers are reduced for the environment, the California State Legislature passed landmark legislation in 2009 (CA Water Code SS 85054) that established “Coequal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem? The legislation also stated that “The coequal goals shall be achieved in a manner that protects and enhances the unique cultural,

recreational, natural resource, and agricultural values of the Delta as an evolving place.?Further, the State of California and Federal Agencies have stated that management decisions should be based on the best-available science. This presentation describes the challenges of integrating policy, management and scientific research and progress that has been made since 2009.

 

 

SPEAKER: Peter Goodwin serves as the President of IAHR and has just completed a federal appointment as Lead Scientist for the Science Program of the Delta Stewardship Council in California. He is the DeVlieg Presidential Professor of Civil Engineering and founding Director of the Center for Eco-hydraulics Research at the University of Idaho. His research interests include systems approaches to ecological restoration of river, wetland and estuarine systems.

Seminar Open-channel turbulence: recent advances and implications for river engineering and stream ecology


by Prof. Vladimir Nikora

 

6th Century Chair in Environmental Fluid Mechanics, School of Engineering, University of Aberdeen, UK

 

 

Date:           August 18th 2016, Thursday

Time:                     5:30 - 6:30 p.m.

Venue:        Room IAS2042, HKUST Jockey Club Institute for Advanced Study, Lo Ka Chung Building, Lee Shau Kee Campus, The Hong Kong University of Science and Technology

 

ABSTRACT: Open-channel flow (OCF, e.g., streams and rivers) occupies a special place in a family of turbulent flows. It may exhibit a set of properties that make this flow unique and exciting, i.e.: (1) flow boundaries (sedimentary bed and free surface) can be highly ‘deformable?and dynamic, constantly changing in response to varying flow; (2) channel surface may exhibit a complex hierarchical structure covering scales spanning 7-10 orders of magnitude; (3) aquatic biota may significantly influence flow and its boundaries; and (4) flow submergence (i.e., ratio of the flow depth to the height of prevailing roughness elements such as sediment particles, their clusters, bedforms, or benthic organ-isms) may be as low as 1-4. This talk will highlight the latest advances in studies of OCF turbulence, including turbulence statistics and coherent motions, with particular focus on ‘superstructures?(or ‘very large scale motions?up to 40-50 flow depths in length). This will be followed by consideration of turbulence effects in sediment transport, flow-biota interactions, and hydraulic resistance.

Seminar - Coupling of Urban Hydrology, Tunnels and Chicago Waterways Models


by Prof. Marcelo H. GARCIA

 

Professor & Director, Ven Te Chow Hydrosystems Laboratory

University of Illinois at Urbana-Champaign

 

 

Date:           August 16th 2016, Tuesday

Time:                     6:00 - 7:00 p.m.

Venue:        Room IAS2042, HKUST Jockey Club Institute for Advanced Study, Lo Ka Chung Building, Lee Shau Kee Campus, The Hong Kong University of Science and Technology

 

ABSTRACT: Chicago is a major world metropolis that has undergone significant levels of population and economic growth over a period of over 100 years. Along with this growth has been the accompanying growth of urban drainage infrastructure, which has reached a level of complexity that’s difficult to understand. Managing such an urban drainage system to achieve acceptable levels of performance and protection from urban flooding and water quality degradation is already a multi-billion dollar activity. Flooding in Chicago occurs at different hierarchical levels. At the first level the sewersheds can cause local (street) flooding when the storm discharge exceeds the capacity of inlets to the Combined Sewer System (CSS) system. At the next level, the CSS system can exceed its capacity and discharge to waterways, the occurrences of which are called combined sewer overflow (CSO) events, as well as to the residential basements, which causes basement flooding (a big issue in Chicago). The CSS system delivers water to the distributed set of treatment plants. When the capacity of the treatment plants (individually or collectively) is reached, overflow from the interceptor system bypasses to the deep tunnel (TARP) system. TARP has cost about $3.2B and provides enormous storage capacity to absorb the enormous volumes of water that occur during severe storm events. One can therefore view the entire Chicago drainage system as consisting of a hierarchy of transmission and storage systems, each of which is governed by capacity constraints, which act as thresholds or bottlenecks –flooding can occur at all of these levels. This presentation will showcase the urban hydrology and hydraulic models developed over the last decade at UIUC to manage the combined sewer system in Chicago, prevent flooding and geysering and the contamination of Lake Michigan-the main source of water for Chicagoland- during extreme hydrologic events.

TOPIC: Eco-hydraulics has become the growth point and one of the most active aspects of water sciences since 2000. China is stepping into a moderately developed country and pays more and more attention to aquatic ecology. Quite many eco-hydraulics problems become the main subjects of research and engineering projects. For instances, fish ladders and fish passages are designed and constructed on the hydro-power dams that constructed in the past decades. Algal bloom has posed a serious challenge to scientists and managers of rivers and lakes. Ecological restoration projects are going to be conducted on rivers and various measures are studied and compared for improvement of ecological conditions. In this talk, Prof Wang will talk about 1. Fish Hydraulics; 2.Invasion of Species into Canals and Water Transfer Tunnels; 3.Habitat Change due to Hydraulic Engineering; 4.Studies on Eco-sedimentation and 5.Restoration of Habitat.

 

SPEAKER: Dr Zhaoyin WANG is professor of the Department of Hydraulic Engineering of Tsinghua University, the Chairman of the Advisory Council of the International Research and Training Center on Erosion and Sedimentation (UNESCO). For his achievement, he won China National Science and Technology Progress Prizes on Vegetation-erosion Dynamics, Sedimentation Study in the Three Gorges Project and Water Resources Management of the Yellow River Delta. ASCE awarded him the 2011 Hans Albert Einstein Award for his unique contributions for understanding of hyper-concentrated flows, debris flows, watershed vegetation-erosion dynamics, stream ecology and restoration, and integrated river basin management.

            Date:   May 21, 2015 (Thursday)

            Time:  6:00 - 7:00 p.m.

            Venue: Room 6-12B, Haking Wong Building, The University of Hong Kong

 

 

ABSTRACT

 

This is a seminar on application of a newly developed flexible mesh model (D-Flow) for typhoon and storm surge in coastal land and water body. Due to the low altitude and frequent number of typhoons, the Pearl River Delta is under the risk of flooding induced by storm surge, which may cause loss of human life and damage to the infrastructures. This research aim to estimate the storm surge water level during typhoons, and to estimate the inundation area. Combining with the local land use data, it is possible to quantify the economic loss. The D-Flow has been calibrated against field data, and the inundation area is validated against satellite image during the typhoon storm (Utor, 2001). Results of this research will help to relief the human and economic loss, also improve the land use planning and sustainable development in the coastal and delta area.

Seminar - Simulation of Near-field and Far-field Dispersion of Pollutants in Coastal Waters (16February 2015, Monday)

 

by Dr. K. L. Pun

 

Vice Chairman, IAHR-HK; Head, Department of Civil Engineering, Chu Hai College of Higher Education.

 

 

 

            Date:   February 16, 2015 (Monday)

            Time:  6:30 - 8:00 p.m.

            Venue: HKIE Headquarter, Causeway Bay

 

 

 

PROGRAMME HIGHLIGHTS

 

Near-field models such as CORMIX, VISJET and VISUAL PLUMES take into consideration the entrainment due to plume momentum and buoyancy in the region near the discharge points. Far-field models such as Delft3D, EFDC and MIKE21/3 are multi-dimensional numerical models simulating advective and diffusive transport processes in coastal waters, and are usually the depth-averaged or layer-averaged models that cannot resolve the near-field dynamics of effluent plumes. The time and spatial scales of pollutant dispersion are short for near-field models and are large for far-field models. As such, the regions of concern by the near-field and far-field models are not the same.

 

This seminar introduces the basic concepts of both near-field and far-field models, and the limitations of the models and their applications. An overview of different approaches for coupling near-field and far-field models to improve accuracy of model predictions is presented.

 

This seminar is jointly organised by IAHR-HK and HKIE EV Division, CA Division and AMC.
