Description

During Day 4 "Water quality and ecology" of the Delft3D User Days the latest advances in tools used for water quality and ecological modelling are presented. Delft3D water quality and ecology users will demonstrate the potential for analysing challenges in both freshwater and salt water systems around the world. The program offers a mix of lectures and hands-on training, all aimed at demonstrating capabilities and disseminating knowledge on the practical use of the tools and models.

“How do salt march ecosystems develop and why are they important?”

“How can we choose the best parameters for water quality models?”

“How can we estimate emissions of emerging contaminants when we have little in-situ measurement data?”

These types of questions are those being studied using a variety of models native to the open source Delft3D Suite and related Deltares software products. In some cases these water quality and ecology models rely on input from hydrodynamic or sediment models for information on flow fields or morphology and in others cases they act as stand-alone models.  The use of these integrated models has led to new developments, insights, and understanding for water management. By combining these water quality and ecological processes into other models within the Delft3D environment, the water quality and ecology modules enable investigators to quantify the processes relevant to aquatic ecosystems, and can help identify and explore potential solutions to environmental problems. 

On this day, we will focus on Water quality and ecology. The event will broken up into two parts seperated by a free lunch.

Presentations (09:00-12:30)

Water quality modellers from the Netherlands and abroad will share their case studies of new applications of water quality and ecological modelling software. Topics will include an emissions modelling framework for emerging contaminants, modelling the hydrodynamics and water quality of tropical lakes, and examining the ecology of salt marshes.

Break-out sessions (14:00-17:30)

Participants will be given the opportunity to participate in two 90 minute break out sessions that showcase some of the newest software tools being employed at Deltares. Topics may include methods to obtain and process remote sensing information with negligible computation power, the modelling of algae populations, and tools for modelling the interaction between vegetation and flow.

14:00 - 15:30 Break-Out Sessions 1
We invite participants to choose two workshops and have some hands-on experience with the software
14:00 - 15:30 Vegetation Modelling in Delft3D Flexible Mesh
With more attention for climate change impacts and sustainability, we get more and more questions on how (semi-) natural systems such as mangroves and saltmarshes can aid in the protection of coasts, and how such systems will develop over time under various forcing scenarios. Rivers pose us with similar challenges: we want valuable nature whilst staying safe from flooding. Such questions require the application of biogeomorphological models to quantify system behaviour and performance. Over the past years, in the framework of the Nature Based Flood Defense speerpunt, we incorporated advanced vegetation representation in DFM and Xbeach. Moreover, we created Python-based tools for the dynamic interaction between vegetation and physics using the fast and easy-to-use Basic Model Interface technique (BMI). In this course, we aim to give you an idea of what you can do with these tools and how to use them, and we would like feedback on what other functionalities you need for the applications you have in mind.
14:00 - 15:30 BLOOM for dummies - phytoplankton modelling with DELWAQ-BLOOM
Eww, that green goop in the water. What is it doing there? Can you do something about it? Let’s find out in the BLOOM II break out session! During this 1.5 hour workshop Tineke Troost and Lilith Kramer will introduce you to the BLOOM II module. BLOOM II focusses on cyanobacterial and algal growth in freshwater and marine water systems and is part of DWAQ. You will learn the basic concepts of phytoplankton growth and how to model it with BLOOM II. Also you will acquire some hands on experience with BLOOM II by setting up, running and checking a tropical application of this module in Deltashell.
14:00 - 15:30 Introduction to Google Earth Engine and Applications for Water Quality
Google Earth Engine (GEE) is a planetary-scale platform for environmental data analysis. It brings together over 40 years of historical and current global satellite imagery, and provides the tools and computational power necessary to analyse and mine that vast data warehouse. Current applications of GEE include: detecting deforestation, classifying land cover and land cover change, estimating forest biomass and carbon, water detection and mapping the world’s roadless areas. This break-out session will very briefly introduce GEE and explain its general workings. Participants will then be shown how to extract estimates of suspended particulate matter levels from a water body of their choosing (almost) anywhere on the globe. Participants will need a Google Earth Engine account if they wish to participate. They may apply for one here: https://signup.earthengine.google.com/

16:00 - 17:30 Delft-FEWS & water quality for dummies - Short intro to processing water quality monitoring data and visualization using html
Delft-FEWS is a software package developed by Deltares to provide an easy and modular way of setting up operational forecasting systems. Due to the modular approach Delft-FEWS allows you to plug in a wide range of data sources, models and data types. This can all be configured in the Delft-FEWS configuration files. In this Delft-FEWS Water quality breakout session some of the features of Delft-FEWS configuration will be explained based on several hands-on exercises and a short introduction by Delft-FEWS experts of Deltares. Delft-FEWS was originally intended for hydrologists and used for Flood Early Warning. Currently Delft-FEWS is used in over 40 countries over the whole world and has expanded its areas of applicability towards droughts, hydropower, coastal systems, water quality, data conversion, shipping, dredging and long term scenario studies.
