Su, X, Liang, Q, Jiang, J (2023) Calibrating a 2D high-performance hydrodynamic model for fluvial process modelling along the Mekong River, The Vietnamese Mekong Delta (VMD), representing a highly complex hydrodynamic system, plays a major role in food security and socio-economic development in Vietnam. With ongoing climate change and rapid urbanization, the VMD is increasingly vulnerable to flood risk from multiple sources, e.g. driven simultaneously by fluvial, pluvial and coastal processes. It is essential to develop reliable modelling tools to simulate such compound flooding processes to support hazard risk assessment and management to inform the development of policies and effective strategies to sustain the delta development.To support reliable compound flood modelling and risk assessment in VMD, it is important to accurately predict the fluvial processes along the Mekong River. For large river and river network modelling, one-dimensional (1D) and quasi two-dimensional (2D) hydrodynamic models are commonly used. However, modelling overbank flow and flooding process over floodplains is out of the capability of these 1D or even quasi 2D models. These 1D or quasi 2D models are then integrated with a 2D inundation model through one-way coupling to predict the flooding processes in floodplains. The resulting one-way coupled models neglect the dynamic interactions between the flows in the river and floodplain as well as upstream and downstream domains, inevitable introducing model uncertainties that are difficult to quantified and controlled. Ideally, we can use a full 2D hydrodynamic model to simulate the entirely fluvial flooding process spreading from the river channels over to the floodplains. However, this approach has not been widely reported for large-scale application due to the prohibited computational cost of a 2D hydrodynamic model.In this work, we explore the possibility of calibrating a fully 2D hydrodynamic model, the High-Performance Integrated hydrodynamic Modelling System (HiPIMS), to reproduce high, medium and low flood conditions along the middle and lower reaches of Mekong River of 55 km, starting from the Kratie gauge in Cambodia to avoid tidal influence. The model is driven by inflow at Kratie and calibrated using the measurements of both water level and discharge available at 4 gauge stations (Can Tho, My Thuan, Chau Doc, Tan Chau). The Nash-Sutcliffe efficiency (NSE) is used to quantify prediction errors to support the model calibration process.. DOI: 10.5194/egusphere-egu23-16380.

Xia, X, Jarsve, K, Dijkstra, T, Liang, Q, Meng, X (2023) An integrated hydrodynamic model for flash flood and debris flow simulations, Climate change is forecasted to result in more frequent and intense storms, which in turn are likely to cause more flash floods and other hazardous processes in steep hilly and mountainous catchments. These flash floods are driven by complex and rapid overland flow responses to intense rainfall across these catchments. Where loose slope or valley-based deposits are available, flood water may mobilise these materials and transform into dynamic high-velocity, high-density debris flows that can pose significant threats to people, property, and infrastructure considerable distances away from the areas where these deposits are mobilised, exacerbating the already devastating situation caused by flooding. Hydro-dynamic models solving the full shallow water equations (SWEs) have shown great potential to reliably simulate the dynamics of overland flows and flash floods at catchment scales. However, simulating the transition from flash flood into debris flow is still technically challenging because of the difficulty of simulating erosion and deposition processes robustly. A reason is that the commonly used method for calculating erosion and deposition rate may suffer from singularity in the presence of vanishing velocity, which poses a major challenge for practical applications. In this work, we have developed a novel integrated hydrodynamic model for simulating flash floods and debris flows. Overland flows, change of debris concentration and bed elevation change are simulated simultaneously to model the transition between flash flood and debris flow. The overland flow processes are simulated by solving the full SWEs using a Godunov-type finite volume method. A novel method for calculating erosion and deposition rates is incorporated into the SWEs-based model to simulate the change of debris concentration and bed elevation change. The new method can maintain numerical stability and accuracy even in the presence of vanishing velocity. Therefore, the new model can effectively simulate the full process of rainfall-runoff-flooding turning into debris flows. Satisfactory simulation results have been obtained for both laboratory-scale and real-world test cases. The new model has the potential to be applied for flash flood/debris flow risk assessment and early warning.. DOI: 10.5194/egusphere-egu23-5869.

Jiang, J and Liang, Q (2023) Evaluating the feasibility and performance of Nature-based Solutions in Can Tho, Vietnam, Can Tho, the largest city in the Mekong River Delta, is experiencing rapid urbanisation that is causing many typical urbanisation-related issues, including the increasing flood risk. The flooding area has expanded from 30% to 50% of the total city area due to urbanisation and climate change. Due to the low topography and poor capacity of drainage systems, the city may sometimes remain inundated for up to three hours after the rain event has ended. It is essential to develop effective and also sustainable management strategies for the city to mitigate risk of flooding, especially surface water flooding caused by extreme heavy rainfall.Nature-based Solutions (NbS) are proposed and widely promoted globally as a sustainable strategy for managing flood risk and creating other benefits. For flood risk management, NbS can help a city reduce surface runoff and subsequently release pressure on drainage systems through infiltration and interception, thus mitigating flood risk. Numerical modelling has been widely used to support the design and assessment of NbS. Conventionally, NbS modelling is achieved by integrating a hydrological model with NbS simulation modules though a one-way coupling method. Such models are incapable of fully describing the rainfall-runoff-flooding processes dynamically interacting with NbS measures, and therefore can only provide limited information such as temporal and spatial variation of runoff removal rate for NbS design and evaluation.In this work, a 2D hydrodynamic flood model is adopted and further developed by coupling with compatible NbS simulation approaches to overcome the existing NbS restrictions. The new modelling framework is applied in Can Tho city to evaluate the feasibility and performance of different NbS against various evaluating metrics. The simulation results indicate that green roofs, rain gardens, and bio-retention cells can effectively reduce inundation area, flow rate, and runoff volume to protect localised infrastructure and key buildings under certain rainfall scenarios. However, dramatic change of flow velocities is observed near the key infrastructure and structures following the implementation of a rain garden, posing higher risk to pedestrians and vehicles. In-depth analysis of the hydrological performance of bio-retention cells further indicates that their designed capacity is not sufficiently exploited due to the inappropriate installation location, further demonstrating the advantage of the proposed model for better planning and design of NbS to achieve optimised performance..

Qin, H and Liang, Q (2023) Development of a Coupled Human And Natural Systems (CHANS) Modelling Approach for flood risk assessment and management, Keywords: CHANS modelling, inundation model, agent-based model, risk assessment, flood risk managementFlooding is the most wide-spreading natural hazard threatening people’s lives and properties worldwide. In recent years, rapid urbanisation and more frequent weather extremes have led to increased risk of flooding, evidenced by the costly summer floods occurred in Europe and China in July 2021 and, most recently, the deadly event affecting most areas across Pakistan. Effective flood risk management is essentially needed to protect people’s lives and properties.Human activities may significantly influence flooding processes and the subsequent risk. However, few flood risk assessment and management practices directly consider human activities and social dynamics. This study aims to develop a Coupled Human And Natural System (CHANS) model to simulate the human-nature interacting processes during a flood event, which is subsequently applied to assess flood impact and evaluate the effectiveness of different disaster management options. The CHANS modelling framework is implemented by coupling the in-house High-Performance Integrated hydrodynamic Modelling System (HiPIMS) and an agent-based model built on the Flexible Large-scale Agent Modelling Environment of the Graphics Processing Unit (FLAMEGPU). The agent-based model simulates the complex behaviours of individuals and households reacting to the dynamic flooding process predicted by HiPIMS. The new CHANS modelling framework is tested by simulating the household damage caused by the 2015 Desmond flood in the 2500 km2 Eden Catchment in England, and the simulation results are consistent with the data released in government reports. The model is further applied to explore the role of early warning and sandbagging in mitigating flood impacts. The validated CHANS flood risk modelling and assessment framework is further applied to the City of Can Tho in the Vietnamese Mekong Delta to assess compound flood risk taking into account dynamic household vulnerability and explore different risk mitigation measures..

Xiong, Y, Liang, Q, Wang, G (2023) Modelling the Dynamics of Multiple Floating Vehicles Driven by Transient Flood Waves, Many post-event field investigations of water-related hazards suggest that debris-enriched flow is much more destructive than water flow alone. However, the role of floating objects is rarely considered in the modelling or risk assessment approaches in practice. Existing modelling approaches are mostly focused on a single or limited pieces of debris. The interactions between the flow and multiple floating objects are not well explored and understood, and few modelling tools have been developed with the capability to simulate and predict these complex interactive processes.This work aims to present a two-way coupling numerical model for simulating the full-process dynamics of floating debris driven by flood waves, based on a finite volume shock-capturing hydrodynamic model solving the 2D shallow water equations and a 3D discrete element method (DEM) model. A multi-sphere method (MSM) is introduced to the DEM model to better capture the shape and size of floating objects. The coupled model estimates the hydrostatic and dynamic forces acting on debris directly using the high-resolution water depth and velocity predicted by the hydrodynamic model, efficiently and automatically capturing the interactive dynamics between transient water flow and floating debris. The model is able to simulate the full-process dynamics of floating debris, including vertical displacement, initiation, horizontal transport, depositing, interaction with and impact on structures.After being validated against experiment tests, the model is applied to reproduce a flash flood event in the coastal village of Boscastle, UK, in 2004. During the event, over 100 vehicles were carried by extreme water flow, which blocked and damaged a couple of downstream bridges, changed the pathway and extent of flooding, and finally moved with the flood water to the river mouth. The coupled model well predicts the flood dynamics, transport processes of floating vehicles, and their final locations. Further numerical experiments are caried out to discover and understand the process of floating debris blocking a bridge and the transport process and spatial distribution of different number of floating vehicles during the flood event. This model potentially provides a new and robust tool to more realistically assess flash flood risk and inform planning and design or urban buildings and infrastructure..

Tong, X, Liang, Q, Zhao, J (2023) A high-performance integrated hydrodynamic modelling framework for large-scale multi-process simulation, Coastal cities are prone to the risks from multiple hazards, e.g, compound floods driven simultaneously by interactive fluvial, pluvial and coastal processes. The overland flow and flooding process of a compound event may further erode soil, move and carry along debris of different size, and pick up and transport pollutants to create secondary hazards to exacerbate the flood impact on assets and environment. When assessing and managing multi-hazard risk, it is essential to have a modelling tool that can depict in detail the flooding and associated processes. However, the traditional flood models seldomly consider and simulate the interactive rainfall-runoff-flooding and associated secondary hazard processes.This work aims to develop and test a high-performance portable modelling framework to simulate the flooding dynamics triggered by multiple drivers, as well as the relevant cascading processes, to support more comprehensive multi-hazard risk assessment and management. To simulate the complex flooding dynamics from multiple sources, the High-Performance Integrated hydrodynamic Modelling System (HiPIMS) developed at Loughborough University is adopted. HiPIMS solves the full 2D shallow water equations (SWEs) using a Godunov-type finite volume method, implemented with novel variable reconstruction and source term discretisation schemes to handle complex domain topography and wetting and drying to achieve stable and accurate prediction. HiPIMS is further implemented on multiple GPUs to achieve high-performance computing to support large-scale high-resolution simulations. In this work, a new version of more compatible and portable HiPIMS is developed by adopting PyTorch (https://pytorch.org) to distribute GPU threads and reconstruct input data and internal variables, making it easier for interfacing with GIS tools and data pre- and post-processing. To ensure the new HiPIMS is extendable to incorporate new modelling components to achieve multi-hazard and multi-process modelling, the main model code is encapsulated to provide interfaces with easy access to hydrodynamic information, i.e, water depths and velocities, for model coupling. Git (a distributed version control system for programmers to collaboratively develop source codes) is further employed to support long-term flexible model development and maintenance.The capability of the new HiPIMS is demonstrated and confirmed by application to 1) reproduce a surface water flood event driven by fluvial and pluvial processes across the 2500km2 Eden catchment in England; 2) initiation and propagating process of floating debris driven by highly transient flood waves; and 3) wash-off, transport and deposition of non-point-source pollutants driven by rainfall induced overland and flood flows over urban surfaces..
