Diving deeper into hydrology research often brings an epiphany: the equation "Storage = Input - Output" is merely the tip of the iceberg. Researchers encounter complexities like parameterizations, as well as biases and errors within datasets. Surprisingly, these critical issues aren't widely discussed as fundamental guidance for graduate studies. Therefore, choosing a dataset is just the beginning; it's equally important to master the appropriate tools for data processing. Given the importance of such issues, Sanaa Hobeichi, Matthias Bittner, Joana Reuss and myself are convening a workshop at #EGU2024 on "Best Practices for Global Analysis of Water Cycle Components: Connecting-the-Dots", particularly crafted to empower graduate students and early career researchers within the realm of hydrology and its related domains. Scheduled on 18 Apr, 16:15–18:00 (CEST), our workshop will cover many critical concepts such as #scaling issues, #errors in observational versus modelled datasets, and #closure problem in hydrology will be discussed with examples of academic #blunders from the past. So, if you are planning to attend #EGU2024, either in Vienna or online, consider dropping-by. For more info, please visit: https://lnkd.in/gBXwVbai #EGU2024 #Hydrology #DataScience #AcademicBlunders

I was reading a book named *Applied Hydrology* by Ven Te Chow, and found a brilliant explanation of hydrologist position: “This is a professional scientific position with their objective to study interrelationship and reaction between water and its environment in the hydrologic cycle. These positions have the functions of investigation, analysis, and interpretation of the phenomena of occurrence, circulation, distribution, and quality of water in the Earth's atmosphere, on the Earth's surface, and in the soil and rock strata. Such work requires the application of basic principles drawn from and supplemented by fields such as meteorology, geology, soil science, plant physiology, hydraulics, and higher mathematics.” This quote captures the multidisciplinary essence of hydrology and its importance in understanding water’s role in our environment. Highly recommend this book for anyone passionate about water resources! #Hydrology #WaterResources #AppliedHydrology #VenTeChow #WaterCycle #Meteorology #SoilSciences #HydrologicalCycle #WaterManagement #EnvironmentalEngineering

📢 📢 📢 Our master student and teaching assistant Lazar Filipovic from Institute of meteorology, Faculty of Physics, Belgrade (Institut za meteorologiju) presented his📈 research within poster session 👉 Mediterranean climate regions of the world: climate change, #variability and #extremes; #impacts and #adaptation at the 💙 European Geosciences Union (EGU) General Assembly 2024 💙 💡Comparison and analysis of #drought indices SPI & SPEI for #Belgrade Quantifying the intensity of a drought is not an easy task, as one has to take into account multiple parameters, for example rainfall 🌦, temperature 🌡 , soil water content 💦, etc. Numerous indices have been developed to tackle this issue, and some of the most widely used are standard precipitation index (#SPI) and standard precipitation evapotranspiration index (#SPEI), which, as the name implies, standardize precipitation and evapotranspiration over a point for a certain time period and use that as a reference for an estimate of available water. 🎯 The goal of this work is to analyze these drought indices for a long-term time period, take a look at their correlation and compare them with available records.  The theoretical difference between the two indices is in the fact that SPEI takes (potential) evapotranspiration into account, while SPI does not. Since sufficient measured evapotranspiration data was not available, potential evapotranspiration was used, calculated by the Thorntwaite method (taking into account temperature and geographical position). 🤔 Check the results, abstract and 🔎 poster presented in the supplementary materials in the following link 👇 https://lnkd.in/d7gdGC99 #EGU #EGU24 #extremes #geosciences #climate #climatechange #drought #science #climatology #meteorology #facultu #university #precipitation #temperature #SPEI #SPI #Belgrade

Book introduction: Hydrology: An Introduction 1st Edition (2005) by Wilfried Brutsaert Water in its different forms has always been a source of wonder, curiosity and practical concern for humans everywhere. Hydrology: An Introduction presents a coherent introduction to the fundamental principles of hydrology, based on the course that Wilfried Brutsaert has taught at Cornell University for the last thirty years. Hydrologic phenomena are dealt with at spatial and temporal scales at which they occur in nature. The physics and mathematics necessary to describe these phenomena are introduced and developed, and readers will require a working knowledge of calculus and basic fluid mechanics. The book will be invaluable as a textbook for entry-level courses in hydrology directed at advanced seniors and graduate students in physical science and engineering. In addition, the book will be more broadly of interest to professional scientists and engineers in hydrology, environmental science, meteorology, agronomy, geology, climatology, oceanology, glaciology and other earth sciences.

WHAT happens if you are too unsteady for the field trips of the South Australian Field Geology Club. WHERE do you go to get geology training if you are in the nursing home? WHEN does the changing world affect my investment portfolio? HOW do I match my tourism snaps to the geological theory? These are questions that have come to me in the last month from Australian Shareholders' Association members. Some investment sites don't help as they either require "sophisticated investor" understanding or just focus on the investment decision. As Fiona Balzer SFFin GAICD explains in the last Equity magazine, this is about reporting from competent persons in AusIMM or Australian Institute of Geoscientists (AIG) using the Australasian Joint Ore Reserves Committee standards. However, the money is made in selling out and analysis of sovereign risk in these days of ESG reporting is a requisite. One website, supposedly pitching geology to the investor, gave: "Lastly, we try to avoid [writing on] projects that are political hot potatoes or located in areas where local issues overwhelm the merits of the project." After a look around I found the Geoscience Australia Pathways videos from several years ago. They cover both mineral resources, infrastructure and hazards. ** Earth Science 101 ** Part 1 Introduction Part 2 Geological Time Part 3 Plate Tectonics Part 4 Rock Cycle ** Resources 101 ** Introduction Part 1 Mineral and Petroleum Systems Part 2 Exploring for Mineral and Petroleum Resources Add to these (in several languages): ** How … surveys work ** Airborne Electromagnetic (AEM) Magnetotelluric (MT) Passive Seismic Ideal for the perspective of Aged Rights Advocacy Service (SA) Inc. all videos have the advantage of having been presented to Canberra staffers, and so unlike the usual Geology education material, assume you have general knowledge and life experience.

I'm so thankful for WEST Consultants, Inc. enabling me to travel to Richland, WA to attend HydroML 2024 and present the work below. I enjoyed the HydroML symposium so much. I was able to make some new friends, connections, and learn a ton! As we continue to generate more and more data the role of ML and AI in managing Earth's resources will continue to grow. Here it is shown that XGBoost (a boosted regression tree) easily outperforms linear models, especially in more arid environments. It is also seen that coupling unsupervised and supervised machine learning methods can produce physically meaningful and interpretable results. With such a wide spectrum of methods now available (regression to deep learning to physically-based models) it is more important than ever to identify the methods fit for your purpose. With intermediate methods, such as XGBoost we get the benefits of not having to impose prior assumptions about the structure of the model as required in standard hydrologic modeling, while also getting interpretable results. #hydrology #machinelearning #civilengineering #waterresources

Excited to share that I am nearing the completion of my PhD in Environmental Engineering at Warsaw University of Life Sciences (Szkoła Główna Gospodarstwa Wiejskiego w Warszawie). Over the course of my academic journey, I have focused on hydrological modeling, climate change impact assessment, and sustainable water management solutions. However, there are still many new topics to learn and explore. I have no regrets about this incredible journey and am still eager to continue in the realm of Hydrology, learning from great researchers. #EnvironmentalEngineering #Hydrology #ClimateChange #Research #PhD #Water
