Background / Problem – The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and subsequent flooding. Flash floods are produced by summer thunderstorms. All of these flood types are compounded by two factors: the storm-sewer system in the City and the elevation of Cayuga Lake. The storm sewers drain to the nearby streams at points below the tops of the streambanks. Because the streamward ends of the storm sewers...
This dataset contains two-dimensional hydraulic models throughout the Willamette River, extending from the McKenzie River confluence, near Eugene, to the city of Newberg. The study reach is separated into five individual models to simplify tributary inflow boundary conditions and for run-time efficiency. These models were developed to assess juvenile salmonid habitat at streamflows ranging from typical low summer flows to roughly the median annual high flow along each reach. Steady-state streamflow conditions were simulated in an unsteady flow simulation by holding streamflow constant for longer periods of time. Underlying these models is a digital elevation model, which combines bathymetric lidar, collected in...

The intense demand for river water in arid regions is resulting in widespread changes in riparian vegetation. We present a direct gradient method to predict the vegetation change resulting from a proposed upstream dam or diversion. Our method begins with the definition of vegetative cover types, based on a census of the existing vegetation in a set of 1 x 2 m plots. A hydraulic model determines the discharge necessary to inundate each plot. We use the hydrologic record, as defined by a flow duration curve, to determine the inundation duration for each plot. This allows us to position cover types along a gradient of inundation duration. A change in river management results in a new flow duration curve, which is used...

The City of Mitchell, South Dakota is exploring ways to improve water quality in Firesteel Creek, which flows into Lake Mitchell. One possible way is to construct a wetland on City-owned land in the Firesteel Creek floodplain above Lake Mitchell, allowing sediment deposition and nutrient uptake by aquatic vegetation in the constructed wetland. In order for a constructed wetland to be designed, information on typical flows and water surface elevations of Firesteel Creek throughout the growing season must be considered. This data release documents datasets and procedures used to estimate that information for a study area encompassing the proposed location of the constructed wetland. Monthly duration curves of daily...

Digital flood-inundation maps were created by the U.S. Geological Survey (USGS) in cooperation with the Bandera County River Authority and Groundwater District and with the Texas Water Development Board for a 23-mile reach of the Medina River extending from Winans Creek to English Crossing, Texas. The flood-inundation maps represent a range of selected water-surface elevations at USGS streamflow-gaging station 08178880 Medina River at Bandera, Texas (hereinafter referred to as the “Bandera station”). Near-real time hydrologic data for estimating areas of inundation near the Bandera station are available from the USGS National Water Information System (NWIS) web interface (https://waterdata.usgs.gov/tx/nwis/) and...
The “Reconnecting Floodplains and Restoring Green Space as a Management Strategy to Minimize Risk and Increase Resilience in the Context of Climate and Landscape Change” project explores green infrastructure opportunities to manage flows, connections, and watersheds in order to improve both flood protection and ecosystem services. This project’s research specifically investigates how restoring floodplains would impact human welfare and environmental conservation. Its research objectives are addressed in two parts: 1) developing a hydraulic model to illustrate how changes in floodplain management may impact flooding along the Connecticut River, and 2) developing a geo-spatial model that demonstrates the distribution...

Summary The Hydrologic Simulation Program – Fortran (HSPF) was applied to the Illinois River Basin using the U.S. Environmental Protection Agency’s (USEPA) Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) system. Values of the HSPF model parameters were based on the calibrations of three representative watersheds within the basin. Over the 1985–1995 simulation period, monthly and annual mass balances correlated well with observed discharges at three gaging stations along the Illinois River. However, poor correlation of daily flows was due largely to the weakness of the HSPF model in routing dynamic flows through the complicated Illinois River system. To address this problem, a one-dimensional...
