Christoph Jan KUELLS "Ecohydrological principles in economic models of water ...Global Risk Forum GRFDavos
This document discusses 4 key ecohydrological principles for modeling water resources in drylands:
1. The response of dryland ecohydrology is slow due to long time scales and residence times of hydrological systems.
2. Dryland ecohydrological systems are nested hierarchical systems with different scaling properties than agronomy and meteorology.
3. Ecohydrological processes have strong feedbacks and non-linear responses, as actions can change the overall system.
4. It is important to balance the cycles of water and solutes to achieve sufficiency, sustainability, efficiency and resilience, as seen in the water and solute cycles of an example system in Windhoek.
This document provides an overview of hydrology and its applications. It defines hydrology as the science of water, and discusses the hydrological cycle and its components. It notes that only 0.69% of the world's total water is fresh water. The document also explains the continuity principle/water budget equation used to describe water circulation. Finally, it discusses some practical applications of hydrology, such as water supply, irrigation, hydropower, flood control, erosion control, navigation, and weather forecasting.
This document provides an overview of hydrology and water resources. Some key points:
1. Only around 2.8% of the world's total water is fresh water, with about 2.2% as surface water and 0.6% as groundwater.
2. India's major river basins and their approximate water potentials are listed, totaling around 188 million hectare-meters.
3. Rivers in north India are perennial as they receive snowmelt runoff, while rivers in peninsular India depend on monsoon rainfall and often run dry outside monsoons.
4. The average annual rainfall in India is around 1,150 mm.

inp.PINS a link between GIS and Storm Water Management Model by Rui Daniel PinaMapWindow GIS
inp.PINS is an application developed to automatically link Geographical Information Systems (GIS) and Storm Water Management Model (SWMM).
SWMM is a public domain software, developed by the US-EPA, widely used for planning, analysis and design of drainage systems. As it is based on physical models, GIS with all the complex functions and modules available is extremely useful to characterize the SWMM base input model, and it is also a powerful tool to store, access, manipulate and visualize the SWMM inputs and results.
inp.PINS has been applied for floodplain mapping (delineation of flood hazard maps) and reveals to be an efficient way to link GIS with SWMM. The interoperability achieved is very effective for the analysis required, since the process leads to an excellent characterization of the catchment and all model inputs, and a better analysis of the modelling results, taking advantage of both GIS and SWMM capabilities at the same time.
inp.PINS is based on MapWinGIS.ocx and is now driven by the community needs the open source community is able to improve the capabilities, and also to make it even more flexible and this communication intends to present and discuss future developments on this project.
This document contains information to set up a stormwater drainage model using SWMM. It includes details on the subcatchments, nodes, conduits, rainfall data, and initial parameters. The model contains 7 subcatchments that drain to 11 nodes connected by 11 conduits and 1 outfall. The document provides tables of properties for each subcatchment, node, and conduit to insert into the model. It describes how to insert the rainfall data and run the model simulations to check results such as flow rates and water levels at each node.
This document provides a quick start tutorial for using SWMM (Storm Water Management Model) software. It describes creating a new project to model a 1.96 hectare urban catchment divided into three sub-catchments that drain into a network of storm sewer conduits and discharge into an open channel. The tutorial explains how to set up the project, draw the objects on the map, and assign properties to the objects.
The document discusses engineering hydrology, which uses hydrologic principles to solve problems related to water resource management and development. It defines engineering hydrology as studying the hydrologic cycle and its components like precipitation, evaporation, infiltration and runoff. Engineering hydrologists work on projects for water control, utilization and management by estimating maximum floods, droughts, water supply and more using statistical and modeling techniques. The key aspects of hydrology discussed are data collection, analysis and prediction.
This document provides an overview of using the Storm Water Management Model (SWMM) to model urban runoff quantity. SWMM can be used to simulate stormwater runoff, combined and sanitary sewers, and other drainage systems. It tracks flow rate, depth, and water quality over time. The document describes modeling runoff quantity using SWMM which requires data on physical catchment characteristics, rainfall, and infiltration. It also provides details on the study area, including subcatchment properties, junction elevations, and conduit lengths.
Flood Forecasting Technology Workshop, Dublin, Ireland
DHI provided a keynote presentation at the recent Flood Forecasting Technology workshop held at University College Dublin (UCD). The one day workshop described some of the internationally available flood warning platforms, suitable for use in Ireland, and provided an opportunity to discuss requirements with both potential users of warning systems and stakeholders who may use their outputs.
The document discusses the development of a storm water forecast system for Singapore using distributed hydrological modeling and radar rainfall data. Key points include:
- A distributed hydrological model (MIKE SHE) using radar rainfall data provided better water level forecasts than previous lumped models using rain gauge data alone, enabling lead times of 10-70 minutes.
- Validation against 11 rainfall-runoff events showed the distributed radar-based model produced more accurate runoff hydrographs and water level forecasts than the previous rain gauge-based model.
- The best forecast performance was achieved for heavy to moderate rainfall events with wide spread coverage, occurring away from the radar location with no attenuation effects and steady storm movement speeds. These types of
Smart Real-time Control of Water SystemsStephen Flood
1) Smart Real-time Control of Water Systems uses Model Predictive Control (MPC) and surrogate models to optimize control of complex urban water systems in real-time.
2) A full-scale test and implementation of this approach was conducted on the urban drainage system in Aarhus, Denmark.
3) Current work is ongoing to further develop the MPC-surrogate modeling framework and its application to integrated control of drainage systems and wastewater treatment plants under changing rainfall conditions.
Real time decision support system in reserrvoir and flood management system f...HydrologyWebsite
This document describes a reservoir operation and flood management system framework. It discusses challenges like meeting multiple water usage objectives, forecasting floods and inflows, and optimizing reservoir operations. Modern IT solutions help manage large data and make robust decisions. The framework includes data collection, forecasting models, dissemination of warnings, and optimization of reservoir operations both for short-term flood management and long-term planning. Case studies from India demonstrate how the system improves flood forecasting and allows more optimal reservoir operations to meet demands while minimizing downstream flood impacts.
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.

This document discusses a hydrology project in India that uses a decision support system (DSS) to analyze water resource scenarios. The DSS integrates tools and databases to help decision-makers analyze alternatives and consequences without an in-depth knowledge of modeling techniques. It provides timely information and allows scenario analysis. The river basin is divided into sub-basins modeled using hydrological and allocation models within the DSS to estimate components like rainfall, recharge, flow, and allocate surface and groundwater resources. The DSS is used to analyze scenarios like reservoir filling likelihoods and risks of low water levels under different planned water allocation scenarios.

Data‐intensive hydrologic modeling: A Cloud strategy for integrating PIHM, GI...lleonardSlideShare
This document discusses using cloud computing to enable data-intensive hydrologic modeling. The goals are to rapidly prototype watershed models anywhere using large national datasets, perform real-time forecasting and analysis, and make models and software accessible via web services. Challenges include the computational intensity of modeling large datasets and distributing complex workflows. The proposed strategy is to develop a PIHM (Pennsylvania Integrated Hydrologic Model) cloud prototype distributing model components and workflows over cloud resources for research and education. This would allow processing large datasets, calibrating models by running hundreds of simulations in parallel, and making models and results accessible online.

DSD-INT 2023 Application of hybrid urban nowcasting in real time operational ...Deltares
Presentation by Mees Radema (Deltares, Netherlands) at the Symposium on Emulating 2D flood modelling, during the Delft Software Days - Edition 2023 (DSD-INT 2023). Wednesday, 27 September 2023, Delft.
The project aims to improve control and operation of a city's water distribution network in real-time using AMR data, hydraulic analysis, and alerts. Over 5,000 water meters connected to the network are monitored. Hydraulic simulations are run hourly to assess pressures, flows, and losses. Abnormal readings and water balances trigger alerts. Future integration of business intelligence is planned to analyze alerts and suggest actions using a knowledge base.
This document discusses how GIS technology is being used to manage large amounts of data for flood control projects in Mecklenburg County, North Carolina. It manages data from over 300 square miles of projects through a centralized database called CECAP. This process streamlines relationships between different agencies and consolidates data from various sources into a single location for easy access. The document provides two case studies that demonstrate how GIS is used to organize massive amounts of survey data, planning data, design data, and more for complex residential and urban stormwater retrofit projects.

Using numerical modelling to regulate a growing aquaculture sector. Rebecca S...Stephen Flood
The document summarizes the use of numerical modeling to regulate Scotland's growing aquaculture sector. It notes that Scotland produces over 179,000 tons of farmed Atlantic salmon annually from over 400 licensed marine farms. Waterbody scale models are being used to better understand flow characteristics and the cumulative impacts of discharge from multiple farms within areas like Colgrave Sound, which has over 20 marine cage fish farms. The models analyze factors like percentage of areas exposed to discharges and impacted by single or multiple sources. They also provide insight into the local versus remote impacts of individual farm discharges. The modeling is helping to drive policy around defining environmental standards that address cumulative impacts at a waterbody scale for aquaculture discharges.
This presentation will cover the extensive application of hydraulic modelling on the national Catchment-based Flood Risk Assessment & Management (CFRAM) programme, as well as discussing the likely future modelling requirements for the detailed development of over 100 flood relief schemes programmed over the coming decade.

My experiences of learning to use MIKE. Jonathan Griffiths, ABPmer.Stephen Flood
"Jonathan will share his experience of learning to use MIKE software for coastal projects over the last 18 months. Previous to joining ABPmer, Jonathan was an oil spill modeller and used specialised spill models such as SINTEF’s OSCAR model, RPS ASA’s OILMAP model and BMT’s OSIS model. Jonathan has found learning to use MIKE a steep but rewarding learning curve. Jonathan will take about some of the differences between these models and MIKE, and the lessons he has learnt along the way."

Using numerical modelling to regulate a growing aquaculture industry. Ted Sch...Stephen Flood
Scotland is currently the largest producer of Atlantic salmon in the EU, and the third largest globally. Exports have doubled in the past decade to nearly £1 billion per annum, and the Scottish Government has specified targets for further expansion. SEPA is working with fish-farmers to help them comply with environmental legislation and to ensure that this growth is sustainable.
Modelling is used to predict the environmental impact of organic material and medicines, and to determine appropriate locations and biomass limits for fish-farms. Traditionally, these farms have been assessed and licensed in isolation, but numerical modelling is increasingly being used to investigate larger scale impacts, cumulative effects, and hydrodynamic connectivity between farms.
MIKE21 models of several water bodies have been developed, with the Particle Tracking module used to predict the spatial and temporal variation of SLICE, a sea-lice medicine. A sub-model of the Scottish Shelf Model developed by Marine Scotland has been converted from FVCOM and is being used to develop a screening tool for assessing the interaction between farms in the Highlands and Islands. By adopting risk-based modelling over a range of scales, SEPA can obtain a better understanding of the environmental impact of fish-farms, influence strategic policy decisions and support sustainable growth of the aquaculture industry.

An Introduction to the Environment Agency extreme offshore wave, water level ...Stephen Flood
This document provides an overview of new extreme coastal event datasets produced by the Environment Agency (EA) for use in flood risk analysis. The datasets were generated using multivariate extreme value modeling of offshore wave, wind and water level conditions, which were then transformed to nearshore conditions using wave modeling. The datasets include over 10,000 years of simulated extreme coastal events that can be used in both robust probabilistic flood risk analyses or simplified analyses. Guidance is provided on applying the datasets for local flood studies.
FAST Danube – Hydraulic and sediment transport modelling with MIKE 21 FM mode...Stephen Flood
The objective of the FAST Danube project is to propose navigation improvement solutions on the Romanian-Bulgarian common sector of the River Danube. The proposed technical solutions would ensure that the required navigation parameters (navigation channel width, depth and bend radius) are achieved at the specified lowest navigation water levels. This would enable safe navigation and transport activities on the Romanian-Bulgarian common sector of the River Danube throughout the entire year.
MIKE 21 FM hydrodynamic and sediment transport models have been developed to help understand the behaviour of the river and the reasons for the changes in river morphology, which result in constraints to navigation at the critical locations. The MIKE 21 FM models are required to support the selection of solution options by providing a first assessment of the relative performance of navigation improvement solutions in maintaining the required navigation fairway parameters. In addition, the MIKE 21 FM models will also provide outputs to support the assessment of the potential impacts of the solutions on navigation conditions and on the river environment. Furthermore, the models will also be used as tools in future management of the river in the project area.
This presentation will focus on the numerical modelling conducted with the MIKE 21 FM model within the FAST Danube project, and how the MIKE 21 FM models are used in the development of navigation improvement solutions and options appraisal process.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

36. Take home messages
• Urban drainage storm water models typically need high degree of detail to
resolve the flooding – it’s important, but data are available today
• Detailed models are slow, too slow – GPU and HPC technology is a game
changer
• With all this speed provided by GPU and HPC, the uncertainty in model set-up
and parameters can be assessed => use speed advantages from GPU
for uncertainty assessment
• Physically based, distributed hydrological modelling and distributed rainfall
can be used in coupled modelling to great effect
