DSD-INT 2017 Urban flood forecasting in central Shanghai (Pudong Area) - ZhangDeltares
Presentation by Weijun Zhang, Ewaters, at the Delft-FEWS - International User Days, during Delft Software Days - Edition 2017. Thursday, 26 October 2017, Delft.
This document summarizes a project to estimate the effects of salinity intrusion due to climate change and sea level rise on the Georgia and South Carolina coasts. The project integrated three models - a global circulation model, a watershed model, and artificial neural network estuary models embedded in decision support systems. The models were calibrated using historical data from two example estuaries - the Pee Dee River basin and Lower Savannah River. The calibrated models were used to predict salinity levels and intrusion events under different climate and sea level rise scenarios to assess vulnerability for coastal utilities. The method developed can help utilities evaluate risks from climate change using existing long-term, site-specific data and modeling tools.

This document discusses satellite-based monitoring of aquatic systems for forecasting and decision making. It describes EOMAP's capabilities for monitoring water quality parameters like turbidity, chlorophyll, and suspended matter using multiple satellite sensors. Validation studies on lakes show strong correlations between satellite and in-situ measurements. The methodology applies corrections to achieve independent, consistent measurements. Services include web applications for analyzing real-time and historical data. Case studies demonstrate applications for bathymetry, dredge monitoring, dam monitoring, and environmental impact assessment.
The document outlines the design of an active control outlet for a stormwater drainage basin in Pelzer, South Carolina. It discusses the background and rationale for the project, which is to improve stormwater management through an adjustable outlet that can be opened, partially opened, or closed based on weather forecasts and pond water levels. This aims to maximize pollutant retention time and better mimic pre-development flow conditions. The document reviews programming approaches to retrieve weather forecast data and integrate it into the control logic to adjust the outlet in real-time.
The document discusses modern approaches to flood forecasting. It begins by noting the importance of data collection and organization for hydrological modeling and forecasting. Key tools mentioned for hydrological modeling include HEC-HMS, SWAT, and SWMM. The document also discusses the importance of using multiple linked models to account for hydrological and hydraulic processes. Examples provided include systems used by ARPAE in Italy and the state of Iowa in the US. These contemporary approaches are characterized as using high-resolution data, multi-objective multi-process models, and cyberinfrastructure to run complex distributed hydrological models. However, the document notes that while such sophisticated systems provide valuable information, there are still open questions around verification at small scales

This presentation was given as part of the EPA-funded Catchment Science and Management Course focusing on Integrated Catchment Management, held in June 2015. This course was delivered by RPS Consultants. If you have any queries or comments, or wish to use the material in this presentation, please contact catchments@epa.ie
It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.

Rijkswaterstaat developed the IWP (Information System for Operational Water Management) to help operators manage water levels across the Netherlands. The IWP provides real-time data, forecasts, and operating advice to operators who control sluices and pumps 24/7/365. It is tailored for each region's needs based on workshops with operators. When fully implemented, the IWP will improve water management and reduce costs while preserving operators' expertise.
The document discusses the development of a Meteo Dashboard decision support system for planning offshore wind farm operations and maintenance. It includes forecasts of waves, currents and water levels from a hydrodynamic model. The dashboard collects and presents measured and forecasted meteorological and hydrodynamic data to support decision making. It has been piloted for RWE's offshore wind farms and includes databases, interfaces for measurements, forecasts from models, and tools to determine weather windows and validate data. The system integrates forecasts from hydraulic models with real-time and historical measurement data from met masts and buoys to provide visualized support for maintenance planning.
Modern tools and techniques can help address challenges in water data management. Water data management platforms use data sharing platforms to integrate data from multiple agencies in a standardized format. These platforms incorporate a hydrological geofabric to establish a single point of truth for water mapping, and use cloud computing to provide scalable access and analysis of large water datasets. For example, a demonstration showed how sensor data, water storage data, and river flow models could be integrated in a sensor cloud to help manage water sharing in a catchment.
The document discusses implementing a groundwater decision support system in Denmark. It describes a 4 step process for building an effective DSS: 1) Create a fast hydrological screening calculator, 2) Set up an intuitive screening paradigm, 3) Identify relevant screening parameters, and 4) Make it a joint effort across stakeholders. The resulting DSS, called BEST, provides a fast yet comprehensive analysis of potential impacts of groundwater extraction on hydrology, nature types, and riverine ecosystems to inform permitting decisions.
This project aims to reduce urban flood risk through an innovative solution called CENTAUR that integrates local sensor networks with data-driven control and a bespoke flow control device. The project brings together universities, SMEs, and water companies to test CENTAUR through full-scale pilot studies in Coimbra, Portugal, accelerating its commercialization. Initial proof of concept testing found CENTAUR can address current local flooding and potentially future flood risk, capturing 100% of flood volumes in simulated events. The project aims to develop the necessary monitoring and control hardware in the first year, with demonstration and implementation in Coimbra in the second and third years.

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Superpower Your Apache Kafka Applications Development with Complementary Open...Paul Brebner
Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!

Alluxio Webinar | 10x Faster Trino Queries on Your Data PlatformAlluxio, Inc.
Alluxio Webinar
June. 18, 2024
For more Alluxio Events: https://www.alluxio.io/events/
Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration
