In disaster-prone regions such as Chile, catastrophe models help (re)insurers to understand and quantify the risks facing their businesses. The 2010 (M8.8) Maule (Chile) earthquake highlighted the need for quantifying losses not only from primary perils (in this case earthquake) but also from secondary perils such as tsunamis, which contribute to the overall event losses but are not often modelled. This paper presents a new catastrophe model for Chile developed by Impact Forecasting (IF) in collaboration with Aon Benfield Research partners. The model has the capability to model losses due to earthquake (ground-shaking) and induced tsunamis along the Chilean coast …

International Conference on Hydroinformatics
The management of water consumption is hindered by low general awareness and absence of precise historical and contextual information. Effective and efficiency management of water resources requires a holistic approach considering all the stages of water usage. A decision support tool for water management services requires access to a number of different data domains and different data providers. The design of next-generation water information management systems poses significant technical challenges in terms of information management, integration of heterogeneous data, and real-time processing of dynamic data. Linked Data is a set of web technologies that enables integration of different data sources. …

New business and technology platforms are required to sustainably manage urban water resources [1,2]. However, any proposed solutions must be cognisant of security, privacy and other factors that may inhibit adoption and hence impact. The FP7 WISDOM project (funded by the European Commission - GA 619795) aims to achieve a step change in water and energy savings via the integration of innovative Information and Communication Technologies (ICT) frameworks to optimize water distribution networks and to enable change in consumer behavior through innovative demand management and adaptive pricing schemes [1,2,3]. The WISDOM concept centres on the integration of water distribution, sensor …

The Research On The Internal Flow Pattern Characteristics Of Steep Slope Tunnel, Xuehai Li, Wen Chen, Heng Li
International Conference on Hydroinformatics
More and more steep-grade tunnels are applied to the hydroelectricdevelopmentof the mountain rivers. The related research and prototype operation show that the hydraulic characteristics of steep-grade tunnel, such as discharge capacity, flow pattern, flow pressure etc. are different from that of slight-grade tunnel. In the article, based on the model test data of steep-grade tunnels in a lot of hydropower stations, the reasons why there are hydraulic characteristics difference existing between steep-grade tunnel and slight-grade tunnel are analyzed, especially about the influencing factors of free-surface-pressure flow and the related control measures. The research results show the influencing factors offree-surface-pressure flowinclude …

International Conference on Hydroinformatics
Adaptive management strategies are increasingly being used by resource managers to optimize complex water delivery systems at the scale of entire watersheds. A variety of models have been proposed to evaluate systems in a piecemeal approach that often times operate at different spatial and temporal scales and prove difficult to integrate with associated field data. In the Deadwood River system of Central Idaho, a series of cascading models was utilized to examine potential impacts of reservoir operations on endangered resident bull trout. Results from integrating limnologic, temperature, nutrient, hyporheic, and hydraulic models show that reservoir operations must remain dynamic depending …

Renewable energy usually refers to those natural sources of energy which are possible to use without diminishing the resource and the current European target is to source 20% of its energy from renewable sources by 2020. The marine current turbine (MCT) is an exciting proposition for the extraction of renewable tidal and marine current power. It is gaining momentum as a viable technology and is currently the subject of much attention and research. However, the numerical predication of the power performance of a marine current turbine under a free surface is difficult due to its complex geometry, fluid-structural interactions and …

Evaluating Alternative Water Allocation Policies Among Competing Users In Bow River Basin, Alberta, Canada, Wei Xu, Nader Khoshroo, Henning Bjornlund
International Conference on Hydroinformatics
Demand for water from rivers and aquifers for consumptive use has grown greatly due to population and economic growth and changing lifestyle and dietary habits. Consequently, aquatic ecosystems, especially in semi-arid and arid regions across the world, suffer adverse environmental impacts of over-extraction. Historically, Alberta’s water allocation system has been based on the first-in-time-first-in-right (FITFIR) system, granting the preference to the licensees based on the seniority of their licenses. In recent years, scientists, policy makers, and water users have raised questions whether FITFIR will continue to be the most appropriate allocation system to manage increasing scarce water resources in Alberta. …

International Conference on Hydroinformatics
This paper describes a hydroinformatic model for generating a Pareto set of LNG terminal layouts that are subject to uncertainty using a multi-objective genetic algorithm. The NSGAII is used to select parameters that propagate through a bespoke LNG terminal design algorithm which includes a Monte Carlo simulator to estimate the uncertainty in each concept. This allows the trade-off between cost and risk to be explored at the earliest stage of design. The results of a case study indicate that nearshore terminals typically have lower capital costs but higher maintenance costs and more uncertainty. The paper concludes that in the example …
Effects Of 2d And 1d Modeling On Mapping Aquatic Habitat Quality, Rohan Benjankar, Daniele Tonina, Jim Mckean
Effects Of 2d And 1d Modeling On Mapping Aquatic Habitat Quality, Rohan Benjankar, Daniele Tonina, Jim Mckean
International Conference on Hydroinformatics
The distribution of aquatic habitat at the organism scale, i.e. 1 by 1m or smaller is typically predicted from local physical characteristics of stream flow, bed, banks and sediment characteristics and a set of biological preference curves. The flow properties are typically predicted with numerical modeling whereas stream bed and bank characteristics defined from interpolated DEM generated by topographical surveys and field observations. Information on the effects of flow properties and streambed morphology due to numerical modeling dimensionality on aquatic habitat modeling is limited. Two-dimensional (2D) modeling is becoming the most popular method to map micro-habitat but its application is …

International Conference on Hydroinformatics
Many hydrologic modelers around the world use Soil Water Assessment and Tool (SWAT) to simulate hydrologic processes, water quality loadings and testing agricultural management scenarios. Once these tasks are complete including publication of results, the models generally are not published or made available to the public for further use and improvement. Although publication or sharing of models is not required for journal publications, sharing of models may open doors for new collaborations, and avoids duplication of efforts if other researchers are interested in simulating a particular watershed for which a model already exists. For researchers, who are interested in sharing …

Emeli 1.0: An Experimental Smart Modeling Framework For Automatic Coupling Of Self-Describing Models, Scott Dale Peckham
International Conference on Hydroinformatics
EMELI (Experimental Modeling Environment for Linking and Interoperability) is a modeling framework written in Python that was designed to explore the possibility of "smart modeling frameworks." As defined here, a smart modeling framework is one that makes it easy for users to couple reusable component models to create new, composite models through the use of a standardized model interface and standardized model metadata. Users make selections from a repository of component models that each provide a CSDMS Basic Model Interface (BMI) for self-description and model control. EMELI then (1) creates a framework object that serves as a container for the …
