Flow-tub model: A modified bathtub flood model with hydraulic connectivity and path-based attenuation

Methodsx (2023)

Kasmalkar I., Wagenaar D., Bill-Weilandt A., Choong J, Manimaran S., Lim T.N., Rabonza M., Lallemant D.

Bathtub flood models are efficient but may overestimate flooding. Hydrodynamic models are accurate but computationally expensive. We present bathtub models as a computationally efficient middle ground for large-scale flood risk analysis.

When floods hit the road: Resilience to flood-related traffic disruption in the San Francisco Bay Area and beyond

Science Advances (2020)

Kasmalkar I., Serafin K., Miao Y., Bick I. A.,Ortolano L., Ouyang D., Suckale J.

Flood-related traffic disruption is not limited to the areas of inundation but has regional, spatially extended impacts.

Traffic accidents and delays present contrasting pictures of traffic resilience to coastal flooding in the San Francisco Bay Area, USA

Urban Climate (2021)

Kasmalkar I., Suckale J.

Prioritizing travel efficiency in transportation adaptation planning may have adverse effects on road safety in the context of coastal flooding.

Integrating urban traffic models with coastal flood maps to quantify the resilience of traffic systems to episodic coastal flooding

MethodsX (2021)

Kasmalkar I., Serafin K.A, Suckale J.

Identifying potentially flooded roads is more complex than just overlying the road network on top of a flood map. We propose corrections to road geometry, elevation and the identification of road-creek crossings.

Shear Variation at the Ice-Till Interface Changes the Spatial Distribution of Till Porosity and Meltwater Drainage

Journal of Geophysical Research: Earth Surface (2021)

Kasmalkar I., Damsgaard A., Goren L., Suckale J.

Using a discrete element model we show how a glacier deforms the underlying soft sediment, leading to increased porosity, and potential changes meltwater flow and yield strength.

Spatial heterogeneity in subglacial drainage driven by till erosion

Proceedings of the Royal Society A (2019)

Kasmalkar I., Mantelli E., Suckale J.

Meltwaters films underneath ice streams may expand and evolve by carving into the sediment beneath, with implications for subglacial drainage.

Ergodicity and conservativity of products of infinite transformations and their inverses

Colloquium Mathematicum (2016) 

Clancy J., Friedberg R., Kasmalkar I., Loh I. ,Pădurariu T., Silva C., Vasudevan S.

Can there be an infinite-measure transformation T such that T xT is ergodic but T x inv(T) is not? We provide an example.

On the Sendov Conjecture for a Roots Close to the Unit Circle

Australian Journal of Mathematical Analysis & Applications (2014) 

Kasmalkar I.

Proves a special case of a very distinctive conjecture about complex polynomials that, if all the roots lie within the unit circle then every root is close to some root of the derivative.
