Unit 5: Mapping the Impact of 100 and 500-year Floods part of Flood Hazards
Most often, we characterize floods based on their return periods. Considering new land developments and the changing climate, what was once a 100-year flood may change over time. Thus, if we are going to experience ...

Unit 4: Hydraulic Modeling and Flood Inundation Mapping using HEC-RAS part of Flood Hazards
The flow or discharge value in a river does not mean much to a layperson or a decision maker because this flow can be insignificant on a big river but can be dangerous on a small creek. Thus, we must know how to ...

Unit 3: Channel Capacity and Manning's Equation part of Flood Hazards
A flood occurs when the flow rate in a river exceeds the capacity of a channel to transmit water downstream within its banks. How much water can a channel transmit? Answering this question requires measurements of ...

Extract Earth Observations using HydroGlobe part of Data and Model Driven Hydrology Education:Steps
The objective of this step is to download MODIS evapotranspiration data for a geographic region. This step is created for some testing purposes and should not be used for any instruction at this point.

Downloading Climate Data from the National Climatic Data Center (NCDC) part of Data and Model Driven Hydrology Education:Steps
This step demonstrates how to use the National Climatic Data Center's (NCDC) web interface to get 15 minutes interval historical precipitation data for a climate station in the United States. This step is ...

Downloading Historical Instantaneous Streamflow Data from USGS part of Data and Model Driven Hydrology Education:Steps
This step demonstrates how to use the United States Geological Survey's (USGS) instantaneous data archive (IDA) interface to get 15 minutes interval historical streamflow data recorded at a USGS gauging ...

Developing a Rational Method Hydrograph Model for the Urban Desert Southwest USA part of Data and Model Driven Hydrology Education:Steps
This spreadsheet based stormwater hydrograph modeling module applies the widely utilized Rational Method to estimate hydrographs and flooding for urban watersheds. The specific structure of the model is based on ...
