Hydrology Newsletter

It is a pleasure to invite you to join the Hydroinformatics Bundle , a curated set of very short‑term courses designed to help you confidently apply modern data and computational tools to real‑world water and environmental problems. What the Hydroinformatics Bundle includes The Bundle brings together multiple compact submodules that cover the breadth of hydroinformatics: Foundations of Hydroinformatics Core ideas linking hydrology, hydraulics and informatics in an integrated framework. Artificial Intelligence for Water Systems Using AI and machine learning for prediction, simulation and optimization in surface and groundwater systems. Nature‑Inspired and Classical Optimization Genetic algorithms and other optimization methods for multi‑objective and multi‑attribute water resources decisions. GIS and Remote Sensing in Water Resource Management Spatial analysis, map creation and satellite‑based assessments for watershed, groundwater and flood studies. Surfer and Visualization Tools for H...

Dear reader, I hope this message finds you well in your work on water resources and environmental engineering. Over the past few years, I have been building the HydroGeek Newsletter as a focused space for sharing insights, tools, and updates related to hydrology, water treatment, GIS-based analysis, and multi-criteria decision making. I am now expanding HydroGeek with a dedicated section on job openings and higher education opportunities specifically relevant to water resource engineers, hydrologists, and environmental professionals. This includes academic positions, research fellowships, project and consultancy roles, PhD/MTech admissions, international scholarships, short courses, and summer schools that align with our domain. My aim is to create a like-minded community where we can: Stay informed about new career and research opportunities in India and abroad. Learn about upcoming calls for applications, funding schemes, and collaborative projects. Share information on suitable pos...

Dear reader, I hope you are doing well and finding time to stay curious about water, climate, and our changing environment. As June 2026 draws to a close, I wanted to briefly share what policymakers, researchers, and practitioners across the world are talking about in the water resources domain, and how these conversations connect to our ongoing discussions in HydroGeek. This month, there has been renewed attention on climate-linked extremes and the need for more adaptive and holistic water management, especially in vulnerable regions facing floods, droughts, and water quality degradation. Editorials and policy notes emphasize integrated approaches that combine hydrological modelling, nature-based solutions, and better governance to deal with compound risks rather than treating floods, scarcity, and pollution as separate problems. These themes resonate strongly with our regular focus on watershed-scale planning, GIS-supported assessment, and multi-criteria decision making for priorit...

1.TOPSIS is best described as A single-objective optimization method for continuous design variables A compensatory MCDM method for ranking finite alternatives across multiple criteria A simulation technique for stochastic hydrologic models A clustering algorithm for grouping similar alternatives 2.In TOPSIS, the Positive Ideal Solution (PIS) represents The alternative with the smallest Euclidean norm in the decision space A hypothetical alternative with the best performance on every criterion The real alternative that appears first in the decision matrix The average of all alternatives over all criteria 3.The Negative Ideal Solution (NIS) in TOPSIS is The worst-performing actual alternative in the dataset A hypothetical alternative with the worst value of each criterion The alternative with the largest index in the matrix The alternative that violates the most constraints 4.For benefit-type criteria (to be maximized), the PIS component is taken as The minimum observed val...
