Prof P P Mujumdar's group published a new article in Nature Scientific Reports. The article examines concurrent meteorological droughts and heatwaves.

Abstract: The impacts of concurrent droughts and heatwaves could be more serious compared to their individual occurrence. Meteorological drought condition is generally characterized by low rainfall, but impact of such an event is amplified with simultaneous occurrence of heatwaves. Positive feedback between these two extremes can worsen the rainfall deficit situation to serious soil moisture depletion due to enhanced evapotranspiration. In this study, the concurrence of meteorological droughts and heatwaves is investigated in India using Indian Meteorological Department (IMD) high resolution gridded data over a period of 60 years. Significant changes are observed in concurrent meteorological droughts and heatwaves defined at different percentile based thresholds and durations during the period 1981–2010 relative to the base period 1951–1980. There is substantial increase in the frequency of concurrent meteorological droughts and heatwaves across whole India. Statistically significant trends in the spatial extent of droughts are observed in Central Northeast India and West Central India; however, the spatial extent affected by concurrent droughts and heatwaves is increasing across whole India. Significant shifts are identified in the distribution of spatial extent of concurrent drought and heatwaves in India compared to the base period.

Job Location: Noida
Modeler – Hydrology or Water Resources, RMS  - NOIDA


RMS is the world's leading provider of analytics and decision science solutions for the quantification and management of catastrophe risks.  The models and consulting services of RMS are used by hundreds of insurance and reinsurance companies, hedge funds, corporations, and governments to assess a wide-range of natural and man-made perils such as - earthquake, flood, windstorm, terrorism, and disease pandemic.  RMS continues to grow and diversify to service and meet the requirement of its clients through research and technology innovation and superior client service.  The company's strength lies in its ability to use and develop the skills of its people across a wide remit of business activities.


The Model Development Department at RMS is responsible for the development of models to assess the risk from natural and man-made catastrophes. A group in Noida works in close collaboration with colleagues in Europe and US, to help quantifying catastrophe risk across all of RMS's products and services.

Objective of the role

Looking for a skilled scientist/technical specialist as catastrophe risk modeler, or a similar role to be a part of model development team that develops probabilistic flood models. He/ she should have an in-depth understanding of hydrodynamics, hydrology, hydraulics, and a good understanding of the integration of data and models. He/ she should have good problem-solving and communication abilities and adapt to work in a quick-paced and project oriented environment.

Key Accountabilities

·         Responsible for understanding, analyzing & developing hydrological models for development of flood hazard model, loss model, calibration and validation
·         Communication and interaction with colleagues in global offices
·         Responsible for research driven process enhancement initiatives in flood modeling
Experience Required

·         Sound knowledge of hydrological and hydraulic processes and modelling
·         Command in one or more of the programming languages: Python, R, FORTRAN, MATLAB
·         Knowledge of C#, C++, JavaScript would be valued
·         Linux/Shell scripting for data management
·         Experience working with large datasets
·         Basic knowledge and interest in catastrophe risk insurance industry
·         D. or Post Graduate in Water Resource Engineering/Hydraulics Engineering/Hydrology with 3 to 5 years or research or industry project experience from a reputed institute

Indian Institute of Remote Sensing (IIRS), a Unit of Indian Space Research Organisation (ISRO), is a premier institute for capacity building and research in the field of remote sensing and geoinformatics. IIRS invites applications for the posts of scientist/engineer-SC.

Can anyone tell me what is the difference between Seasonal and Interannual variation with some suitable example ? I have searched a number of places but the definition of the terms are not clearly stated.

Data / Orbiting Carbon Observatory 2
« on: September 12, 2014, 08:30:55 PM »
This a new satellite launched on 2nd July 2014. Earth satellite mission designed to study the sources and sinks of carbon dioxide globally.

Researchers who study the interaction of plants, carbon and climate are eagerly awaiting data from NASA's upcoming Orbiting Carbon Observatory-2 mission on a nearly invisible fluorescent glow emitted from the chlorophyll contained within plants. Hence this can also be useful for hydrologists.

The first link below talks about the mission. The second one describes the alternative use that it can be put into.

Dear Sat and all moderators

I have an Idea:
Once a person joins the forum, if they can be automatically directed to the Introduction board, as a part of being a member, we will easily get to know who has joined and they will get a feel how to post and better familiarize with the forum.

Secondly, the forum is slow I feel, can we do something about it ?

Hello All

We need to make the forum more active and increase the number of meetings.
Let us all first make sure that all the present students of the WREE group have joined the forum.
Secondly we should start inviting our alumni in the forum and publicize the facebook page (
