FPS are monitoring stations that track the amount of water in streams and rivers across the Nation to meet long-term federal information needs. They are strategically positioned to serve as a backbone for the larger National Streamflow Network that is operated in cooperation with over 1, federal, state, tribal, and local agencies. Flooding is the most widespread hydrologic hazard in the United States and throughout the world. A recent compilation of data on events leading to declarations of disasters under the Stafford Disaster Relief and Emergency Assistance Act indicates that of the declarations during the period December to May , one-third were due to flooding (Godschalk et al., ).
Thematic GIS Data Sets for Water Resources Many USGS studies of water resources have used a Geographic Information System (GIS) to produce digital geospatial data sets for a wide variety of water topics.

Students use the USGS streamflow database to download measured stages and flow data. Working with these data, students use Excel to create several plots, including a stage-discharge rating curve. Students repeat this activity with an urban and a rural watershed to consider seasonal trends and land use effects. Get this from a library!

This interim report describes streamflow characteristics at each bench-mark site and identifies time trends in annual streamflow that have occurred during the data-collection period. The streamflow characteristics presented for each streamflow station are (1) flood and low-flow frequencies, (2) flow duration, (3) annual mean flow, and (4) the serial correlation coefficient for annual mean discharge.

Streamflow Q estimation in ungauged catchments is one of the greatest challenges facing hydrologists. Observed Q from to small-to-medium-sized catchments (10–10 km 2) around the globe were used to train neural network ensembles to estimate Q characteristics based on climate and physiographic characteristics of the catchments.
In total, 17 Q characteristics were Cited by: The “deficit-below-threshold” (DBT) method is applied to characterize low flows in terms of volume, duration and intensity at Canadian hydrometric stations. The volume, duration and intensity data series are fitted to six 2-parameter distributions, which are the generalized Pareto (gp), gamma, Weibull, log-logistic (llog), lognormal.
The latter highlights the need to benchmark both simulation and forecasting outputs from hydrological models, as done in this study, to fully understand and assess model performance. The raw ensemble streamflow forecasts show more skill than the deterministic (unperturbed GEFSRv2 member) forecasts across lead times of 1–7 by: 8.
1 Introduction. Streamflow is the volumetric discharge expressed in volume per unit time (typically cubic feet per second (ft3 /s) or cubic meters per second (m 3 /s)) that takes place in a stream or channel and varies in time and space. The streamflow characteristics of the stations are variable.
Some of the sites are dominated by steady ground-water flows, and others have snow-dominated hydrographs where a large part of the flow results from the melting of the annual snowpack. Given the selected streamflow characteristics and VIC model parameter sensitivity analysis by Demaria et al., three VIC parameters controlling the generation of surface and subsurface flow were selected for calibration (Table 1), including the variable infiltration curve parameter (b i), thickness of soil layer 2 (thick 2), and fraction of the maximum velocity of base flow at which nonlinear base flow Cited by: 1.
We use daily streamflow data from three gauging stations located within the study catchment (Lunz am See, Seebach, and Goestling, see Figure 2). An additional daily streamflow time series recorded at a nearby location (i.e., Opponitz) located downstream in the study network is also considered in the analysis, as explained in detail by: Reservoirs have been continuously built in the Poyang Lake Basin (PLB) for the local economy.
With pending removal and reconstruction of aging reservoirs and planning of new reservoirs in this area, it is advisable to evaluate the likely impact of the existing and alternative reservoir network layouts on the hydrologic regime for more effective water resources planning and management.
The Hydrologic Benchmark Network (HBN) consists of 37 watersheds that provide long-term measurements of streamflow and water quality in areas that are minimally affected by human activities.
In measurements of aquatic biology and soil chemistry were added to the network. The Watershed Characteristics Approach (WCA) is a hydrologic estimation model developed using a system-based approach focused on the regionalization of landscape characteristics to define unique.

Author: Keith J. Beven. A hydrograph is a graph showing the rate of flow versus time past a specific point in a river, channel, or conduit carrying rate of flow is typically expressed in cubic meters or cubic feet per second (cms or cfs).
It can also refer to a graph showing the volume of water reaching a particular outfall, or location in a sewerage network. Graphs are commonly used in the design of.

Joseph Poracsky. Portland State University ©Author: Matthew Lawton Wood.The disaggregated streamflow from the first model explained 69% of the streamflow variance, compared to 71% when the hybrid model was used. Based on the results, the proposed hybrid model that uses both SST and a forecasted JJAS seasonal rainfall as predictors achieves a marginally better forecasting skill of the UBNB weekly streamflow.
Abstract. The dynamics of hydrologic systems are governed by the interactions between climate inputs and the landscape. Due to the spatial and temporal variability in climate inputs and the heterogeneity in the landscape, hydrologic systems exhibit a wide range of : Bellie Sivakumar, Bellie Sivakumar.
