Floods and Drought
Floods and Drought
Natural hazards, such as floods and droughts, can have long-term impacts on communities. By mapping the extent of floods and studying how water managers can best manage water resources, the USGS Nebraska Water Science Center is helping mitigate the effects of natural hazards.

Assessing drought resilience of the South Loup River using age tracer, streamflow, and continuous water-quality data
Streams in the Loup River basin have a close hydrologic connection between groundwater and surface water. Groundwater springs are important hydrologic features that sustain the flow of the South Loup River. This study assesses the ability of these springs to maintain consistent flow of the South Loup River over periods of prolonged drought.
Groundwater/surface-water interaction near the confluence of the Elkhorn and Lower Platte Rivers
Recent droughts in Nebraska (2000–06; 2012–13) have amplified concerns about the long-term sustainability of groundwater and surface-water resources as well as concerns about the effect of groundwater irrigation on streamflow and water supplies needed to meet wildlife, recreational, and municipal needs. The Lower Platte River Basin-wide Management Plan is currently being developed jointly by the...
Flood Inundation Mapping
Flood inundation maps are a sequence of maps which show where flooding may occur at different stream levels. These maps can help communities prepare for, understand, and mitigate flood risks in their area.
