My Story

Joe Szilagyi is a research hydrologist and professor in the School of Natural Resources. He is associated with SNR's water faculty and has been at UNL since 1997.

His main research interests include the interaction of surface water and groundwater, hydrological forecasting, regional-to-continental-scale analysis of the hydrologic cycle, and the effect of climate change on it. One of his current research projects involves estimating watershed-to-continental-scale evapotranspiration (ET) by standard meteorological measurements and 1-km resolution Moderate Resolution Imaging Spectroradiometer (MODIS) daytime land surface temperature data. Recent research involving estimating riparian ET from diurnal changes in the stream-flow rate and in the groundwater level are important to the state and nation. His work helps citizens, agricultural producers and decision makers understand how groundwater and surface water communicate with each other, and how ET is distributed in space over the watershed, which helps in local and catchment-scale water management tasks and irrigation-impact studies.

He also has an example of his work in regional ET estimation with CREMAP in this website site's data section.

Drought Year (2002)

The distribution of ET over the Elkhorn watershed in a drought (2002) year.

Wet Year (2007)

The distribution of ET over the Elkhorn watershed in a wet (2007) year.

The distribution of ET over the Elkhorn watershed in a drought (2002) and in a wet (2007) year. Note how the rangelands of the Sand Hills in the western part of the watershed become much drier in a drought year than the rest, mostly irrigated soybean and corn, of the catchment.
