The goal of the paper is to confirm relationships identified by a paper written in 2017 (Crow et al.) that relates antecedent soil moisture to runoff production. The paper investigates total runoff production during individual rainfall-runoff events in agricultural landscapes as a function of antecedent soil moisture, total rainfall, and vegetation cover for catchments in […]

The authors analyzed the results of the Land Surface Model and the Routing Application for Parallel Computation of Discharge. The authors took the results – which showed that enhancements were still possible for the programs – and investigated the source of the errors. Their research resulted in an improvement in model performance.   ElSadaani, M., W.F. […]

The authors propose a hydrologic evaluation framework for gridded rainfall products. The framework will aid in the compilation of rainfall data and lower the chance for errors with satellite rainfall products in hydrologic applications.   ElSadaani, M., W.F. Krajewski, and D.L. Zimmerman, River network based characterization of errors in remotely sensed rainfall products in hydrological applications, Remote […]

The analysis of unique rainfall-runoff data can offer more in-depth knowledge than the current internal spatial variability of small-scale runoff yield. Through the use of 12 unique hills, the authors intend to reduce the error of runoff data.   Chen, B., W.F. Krajewski, M. Helmers, and Z. Zhang, Spatial variability and temporal persistence of event […]

NEXRAD collects and stores rainfall data in a cloud, allowing the IFC to develop a program to retrieve the data and create a map. The map has the benefit of allowing researchers to choose a specific area of study.   Seo, B.-C., M. Keem, R. Hammond, I. Demir, and W.F. Krajewski, A pilot infrastructure for searching rainfall […]

Reflectivity measurements are one example of a measurement that can be taken from GPM, DPR, and NEXRAD radars. This study demonstrates the potential use of the NASA’s Global Precipitation Measurement (GPM) Dual-frequency Precipitation Radar (DPR) to examine ground radar (GR) miscalibration and other uncertainty sources (e.g., partial beam blockage).   Keem, M., B.-C. Seo, W.F. Krajewski, […]

A stochastic model was created to create high resolution surface soil moisture information.   Jadidoleslam, N., R. Mantilla,W.F. Krajewski and M. Cosh, Data-driven stochastic model for basin and sub-grid variability of SMAP satellite soil moisture, Journal of Hydrology, 2019 (in press).

We’re sorry—due to high registration, we are no longer accepting RSVP’s for daytime activities. BUT you can still join us for the evening social event and flood panel discussion at Big Grove Brewery—no RSVP required! Flood experts will highlight accomplishments over the past ten years, as well as discuss innovative, forward-thinking ideas for how to move […]

The central hypothesis of a nonlinear geophysical flood theory postulates that, given space‐time rainfall intensity for a rainfall‐runoff event, solutions of coupled mass and momentum conservation differential equations governing runoff generation and transport in a self‐similar river network produce spatial scaling, or a power law, relation between peak discharge and drainage area in the limit […]
