Setting Priorities On The Functional Status Of Hydraulic Structures In Mountainous Catchments, V. Juliette Cortes, Simone Sterlacchini, Thom Bogaard, Simone Frigerio, Luca Schenato, Alessandro Pasuto

International Conference on Hydroinformatics

The frequent inspection of hydraulic structures in mountain catchments is important due to the changing interaction among water-related processes that take place in the context of hydro-meteorological hazards such as debris flow and flash floods. At first level inspections, reports from survey protocols carried out by trained citizen-volunteers are combined to provide an index that represent the status of the structure. The survey protocols aim at identifying needs for cleaning of obstructions or to pre-screen potential problems for a second level inspection or more technical and detailed inspection. Thus, reports are focused on the functional status for the following parameters: …

Opensdm - An Open Sensor Data Management Tool, David Camhy, Günter Gruber, David Steffelbauer, Thomas Hofer, Dirk Muschalla

International Conference on Hydroinformatics

Exchange of scientific data and metadata between single users or organizations is a challenging task due to differences in data formats, the genesis of data collection, ontologies and prior knowledge of the users. Different data storage requirements, mostly defined by the structure, size and access scenarios, require also different data storage solutions, since there is no and there cannot be a data format which is suitable for all tasks and needs that occur especially in a scientific workflow. Besides data, the generation and handling of additional corresponding metadata leads us to the additional challenge of defining the "meaning" of data, …

Hydrological Impacts Of Climate Change – Challenges, Uncertainty And Limitations, Shreedhar Maskey, Yurong Hu, Anshul Agarwal, Dinesh Bhatt Aug 2014

Hydrological Impacts Of Climate Change – Challenges, Uncertainty And Limitations, Shreedhar Maskey, Yurong Hu, Anshul Agarwal, Dinesh Bhatt

International Conference on Hydroinformatics

How climate change impacts water resources in the future is an important question that all hydrologists want to have an answer. Climate prediction scenarios are available from many Global Circulation Models for the 21st century. These prediction datasets are typically used as input to a hydrological model for simulating impacts on hydrology, particularly river runoff, evaporation, and storage changes. Because hydrological models are usually run on a much smaller resolutions than climate models, the climate prediction datasets are usually downscaled to represent local climate for using in a hydrological model. The uncertainty in the GCMs, downscaling and hydrological models makes …

Bayesian Parameter Estimation Of Modified Bartlett-Lewis Rectangular Pulse (Mblrp) Poisson Cluster Model, Hyun-Han Kwon, Jang-Kyung Kim Aug 2014

Bayesian Parameter Estimation Of Modified Bartlett-Lewis Rectangular Pulse (Mblrp) Poisson Cluster Model, Hyun-Han Kwon, Jang-Kyung Kim

International Conference on Hydroinformatics

Stochastic rainfall generators or stochastic simulation have been widely employed to generate synthetic rainfall sequences which can be used in hydrologic models as inputs. The calibration of Poisson cluster stochastic rainfall generator (e.g. Modified Bartlett-Lewis Rectangular Pulse, MBLRP) is seriously affected by local minima that is usually estimated from the local optimization algorithm. In this regard, global optimization techniques such as particle swarm optimization and shuffled complex evolution algorithm have been proposed to better estimate the parameters. Although the global search algorithm is designed to avoid the local minima, reliable parameter estimation of MBLRP model is not always feasible especially …

A New Methodology For Deriving Regional Time Of Concentration Equations Using Gis And Genetic Programming, Soroosh Sharifi, Mahdi Razaz Aug 2014

A New Methodology For Deriving Regional Time Of Concentration Equations Using Gis And Genetic Programming, Soroosh Sharifi, Mahdi Razaz

International Conference on Hydroinformatics

Time of concentration (ToC) is the most frequently utilized time-scale parameter in hydrology which must be estimated accurately to ensure correct simulation of many different hydrological processes. Hydrologists have developed many empirical and semi-empirical methods for estimating ToC which are regional, watershed, and site-specific. Modellers are often confused by the number of ToC estimation methods and formulas and often select an equation without evaluating its correctness which leads to inaccurate simulation results. The importance of deriving and using regional ToC equations has been highlighted in many studies. In this paper, a methodology is proposed for deriving ToC equation(s) for watersheds …

Research And Application On The Coupled Method Of Remote-Sensing And Ground-Monitoring Of Reservoir Storage Capacity, He Zhu, Hongli Zhao, Yunzhong Jiang, Li Wang Aug 2014

Research And Application On The Coupled Method Of Remote-Sensing And Ground-Monitoring Of Reservoir Storage Capacity, He Zhu, Hongli Zhao, Yunzhong Jiang, Li Wang

International Conference on Hydroinformatics

Reservoir storage capacity monitoring is the basis of reservoir operation. The relationship curves of reservoir water level-area and water level-capacity are the significant parameters of storage capacity calculation. With the long-term operation, both on the bottom and bank of the reservoir have erosion and deposition, causing the relationship of water level-area and level-storage changes, which leads to inaccuracy of reservoir storage capacity calculation with the original curves. It is costly to revise the curves of reservoir water level-area and water level-capacity by ground measurement termly. A coupled Method of Remote-sensing and Ground-monitoring of Reservoir Storage Capacity is proposed in this …

Optimal Tank Design And Operation Strategy To Enhance Water Quality In Distribution Systems, Alemtsehay G. Seyoum, Tiku T. Tanyimboh, Calvin Siew

International Conference on Hydroinformatics

Water storage tanks are key components of water distribution networks (WDNs) and are primarily designed and operated to meet demand variations and pressure needs. However, the common practice in the design of WDNs is to incorporate large storage tanks that may possibly create long residence time. Long residence time is a major contributing factor for loss of disinfectant, increased formation of disinfection by products and microbial regrowth. Also, poor choice in tank geometry, location and operation can play a role in deterioration of water quality. Most of the previous approaches on optimisation of WDNs design and operation do not take …

Short-Term Hydropower Optimization Using A Time-Decomposition Algorithm, Jonathan R. Lamontagne, Jery Russell Stedinger Aug 2014

Short-Term Hydropower Optimization Using A Time-Decomposition Algorithm, Jonathan R. Lamontagne, Jery Russell Stedinger

International Conference on Hydroinformatics

Hydropower operations optimization models select a sequence of releases from one or more reservoirs that maximizes the expected benefit while honoring many social and environmental constraints. A 3-tiered time-decomposition algorithm is adopted to compute optimal sub-daily releases for the Harris Station reservoir in Maine, USA. This involves solving nested optimization models, each with a different planning horizon and time-step, where the longer-term planning models inform the shorter-term models. This allows for rapid optimization of short-term operations, while efficiently considering seasonal objectives and constraints. In the case study presented, 6-hr release decisions in a weekly model are made by iteratively solving …

High Performance Gpu Speed-Up Strategies For The Computation Of 2d Inundation Models, Asier Lacasta, Mario Morales-Hernández, Javier Murillo, Pilar García-Navarro, Reinaldo Garcia

International Conference on Hydroinformatics

Two-dimensional (2D) models are increasingly used for inundation assesements in situations involving large domains of millions of computational elements and long-time scales of several months. Practical applications often involve a compromise between spatial accuracy and computational efficiency and to achieve the necessary spatial resolution, rather fine meshes become necessary requiring more data storage and very long computer times comparable to the real simulated process (e.g. 1 month of real-time simulation may require 1 month of computations approximately). Obviously, using conventional 2D non-parallelized models (CPU based) make simulations impractical in real project applications, but improving the performance of such complex models …
