On The Importance Of Remote Sensing Data To Validate A Distributed Dynamic Vegetation Model Applied To A Semi-Arid Basin, Félix Francés, Guiomar Ruiz-Pérez, Marta Pasquato, Chiara Medici, María González-Sanchis, Tarcísio J. G. Fernandes, Antonio Molina, Antonio D. Del Campo

International Conference on Hydroinformatics

Efforts to better understand the components of catchments’ water balance have traditionally been one of the objectives of the hydrological community. Very few hydrological models incorporate vegetation development as state variable. This is beginning to change with the recognition by the hydrological community that biological processes play a key role in catchment’s water balance. In addition, some studies confirm that vegetation density controls most of hydrological processes in semi-arid regions. However, the most of the dynamic vegetation models are too complex to be coupled with hydrological models and they incorporate variables and inputs which are difficult to be estimated across …

Does Hyporheic Intensity Explain Spawning Site Selection?, Rohan Benjankar, Daniele Tonina, Jim Mckean, Daniel J. Isaak Aug 2014

Does Hyporheic Intensity Explain Spawning Site Selection?, Rohan Benjankar, Daniele Tonina, Jim Mckean, Daniel J. Isaak

International Conference on Hydroinformatics

Pool, riffle and runs are streambed features and important habitats for aquatic species. It is well-known that salmonid species utilize these streambed features as spawning site. Pools are characterized by deep water depth, low velocity and gentle water surface slope, whereas riffles are characterized by shallow depth, high velocity and steep slope. Past studies have used hydrodynamic model simulated hydraulic characteristics such as depth, velocity and shear stress to delineate these features. However, the magnitude of these hydraulic characteristics may vary significantly with the discharge and longitudinal slope of the stream. Additionally, these indexes still do not entirely explain the …

Considering The Effect Of Uncertainty And Variability In The Synthetic Generation Of Influent Wastewater Time Series, Mansour Talebizadehsardari, Evangelia Belia, Peter A. Vanrolleghem

International Conference on Hydroinformatics

The availability of influent wastewater time series is crucial for assessing the performance of a wastewater treatment plant (WWTP) under dynamic flow and loading conditions. Given the difficulty of collecting sufficient data, synthetic generation may be the only option. Usually, the main constituents of the influent time series (e.g. flow, COD, TSS, TKN) show periodic, auto-correlation, and cross-correlation structures in time. Therefore researchers have used statistical models (e.g. auto-regressive time series models) for random generation of the influent time series. However, these regular patterns in time could be significantly distorted during rain events (wet weather flow (WWF) conditions) in which …

Extending Occoquan Reservoir Water Quality Model For Stakeholder Involvement, Saurav Kumar, Adil Godrej, Thomas Grizzard Aug 2014

Extending Occoquan Reservoir Water Quality Model For Stakeholder Involvement, Saurav Kumar, Adil Godrej, Thomas Grizzard

International Conference on Hydroinformatics

There has been a paradigm change in water resource management as control of major point sources has improved, and recognition has grown of the importance of diffused pollution. Newer approaches, exemplified by watershed-scale management, emphasize stakeholder involvement to achieve better decision making through negotiation and compromise; and ultimately, better acceptance of final management solutions. Stakeholder participatory involvement in using complex water quality models to understand management scenarios and their impacts is, however, limited. Advanced receiving waterbody and watershed WQ models are complicated and require significant technical expertise in their understanding and use, which is a deterrent to non-expert stakeholder involvement. …

Predicting Iron And Manganese Accumulation Potential In Water Distribution Networks Using Artificial Neural Network, Prasad Devi Tumula, Ebenezer Danso-Amoako

International Conference on Hydroinformatics

In April 2010 the Water Services Regulation Authority in England and Wales, OFWAT, introduced the Service Incentive Mechanism (SIM) which rates water companies on their performance based on customer satisfaction and either reward or penalise them. In view of this, it has become extremely important for water companies to lower customer complaints due to drinking water discolouration; which is approximately 34% of all customer complaints. Presently, most water companies identify high discolouration risk regions in water distribution networks (WDNs) by selecting areas in the network with high Iron (Fe) and Manganese (Mn) concentrations from their random sampling.

Evaluating The Effectiveness Of Regulatory Stormwater Monitoring Protocols On Groundwater Quality In Urbanized Karst Regions, Daniel C. Nedvidek

Masters Theses & Specialist Projects

Non-point pollution from stormwater runoff is one of the greatest threats to water quality in the United States today, particularly in urban karst settings. In these settings, the use of karst features and injection wells for stormwater management results in virtually untreated water being directed into the karst aquifer. Currently, no policies exist specifically to provide water quality protections to karst environments. This study utilized a combination of karst stormwater quality data, along with survey data collected from MS4 Phase II communities, and an analysis of current federal, local, and state water quality regulations, to assess the need for karst-specific …

Examining Group Differences Between Suicidal Veterans Classified As Wish To Live, Ambivalent, Or Wish To Die Using The Suicide Index Score, Brittany D. Morris

Masters Theses & Specialist Projects

A persistent difficulty in the field of psychology is identifying which individuals are at the greatest risk for suicide. Veterans of the US Military are at elevated risk for suicide as compared to the general population. One approach for designating tiers of risk is applying the “Suicide Index Score” to discriminate individuals based upon their reported wish to live (WTL) and wish to die (WTD; Kovacs & Beck, 1977). Brown, Steer, Henriques, and Beck (2005) demonstrated those who indicated a complete WTD and no WTL were at greatest risk to die. The current study expanded on previous research by using …

Developing An Integrated Modelling System For Blue-Green Solutions, Christos Makropoulos, Evangelos Rozos, Cedo Maksimovic

International Conference on Hydroinformatics

Blue-green interventions represent the next level of integration for sustainable cities: that of an integrated urban water and urban green design, operation and management. The key concept is that a more holistic approach would present a win-win scenario, in which urban green would be utilized as infrastructure for water services (e.g. mitigating urban floods) while urban water infrastructure would be used as a source of irrigation for urban green, increasing their performance in a range of services including amenities, reducing heat island effects and increasing ecosystem services. However, this focus on integration brings into sharp relief another need: that of …

A Harmonized Vocabulary For Water Quality, Simon J.D. Cox, Bruce A. Simons, Jonathan Yu Aug 2014

A Harmonized Vocabulary For Water Quality, Simon J.D. Cox, Bruce A. Simons, Jonathan Yu

International Conference on Hydroinformatics

Interoperability of water quality data depends on the use of common models, schemas and vocabularies. However, terms are usually collected during different activities and projects in isolation of one another, resulting in vocabularies that have the same scope being represented with different terms, using different formats and formalisms, and published in various access methods. Significantly, most water quality vocabularies conflate multiple concepts in a single term, e.g. quantity kind, units of measure, substance or taxon, medium and procedure. This bundles information associated with separate elements from the OGC Observations and Measurements (O&M) model into a single slot. We have developed …
