SIRDevelopment of Regional Curves Relating Bankfull-Channel Geometry and Discharge to Drainage Area for Streams in Pennsylvania and Selected Areas of Maryland SIREstimation of Baseline Daily Mean Streamflows for Ungaged Locations on Pennsylvania Streams, Water Years – The discharge records collected by the Geological Survey and other Federal, State, and private agencies at about 7, places in the United States are the records upon which flood-frequency studies are based.

Most of the records are short and the sampling errors are. The United States Geological Survey has a number of stream gages located throughout Pennsylvania. These estimate stream levels, discharges and record them over time.

This data is published on the web and many stations allow users to plot custom graphs. Get updated Pennsylvania river and stream levels from USGS here.

Effects of Urban Development on Floods. By C. Konrad. HYDROLOGIC EFFECTS OF URBAN DEVELOPMENT. Streams are fed by runoff from rainfall and snowmelt moving as overland or subsurface flow. Floods occur when large volumes of runoff flow quickly into streams and rivers.

EFFECTS OF URBAN DEVELOPMENT ON FLOOD DISCHARGE AND FREQUENCY. Climate variability (dry cycles to wet cycles) and land-use change play a significant role, but there is a large amount of uncertainty around the flood quantile estimates (the value of discharge corresponding to the year flood), particularly if there isn’t a long record of observed data at a stream.

A streamgage is a structure installed beside a stream or river that contains equipment that measures and records the water level (called gage height or stage) of the stream.

Streamflow (also called discharge) is computed from measured water levels using a site-specific relation (called a stage-discharge rating curve) developed from onsite water. RECORDS OF THE DEPARTMENT OF PUBLIC WELFARE. Discharge Books, The case book lists any affliction related to the patient’s previous health history, what was believed to be the predisposing cause of the illness, whether the patient had experienced any former illness, whether the present illness had been preceded by any.

StreamStats Application. StreamStats is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes.

The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, and then get basin characteristics.

(3) Estimates of flood frequencies and flood flows at the site of the proposed structure, including such information as can be reasonably obtained regarding actual rainfall and flood flow records on the stream. (4) An analysis of the hydraulic capacity of the proposed structure.

(5) A description of the purposes of the proposed structure. Flood discharge records relating to Pennsylvania streams by Pennsylvania (Book) 7 editions published between and in English and held by 74 WorldCat member libraries worldwide.

As more and more tributaries join together a larger stream network is formed and the master stream, the highest order stream in the system has a discharge that is the sum of all the tributary discharges. When flooding occurs, higher order streams take longer to build up to flood stage than lower order streams and longer for the flood to subside.

While these records may seem short in comparison with some discharge records, our aim is not to discuss or detect any long‐term climate‐related changes in flooding but to show how rapidly the local flood risk can change above NWS categories.

Trends in Flood Frequency. Although geomorphological methods of flood series extension have been widely used in the British uplands, records for Wales are restricted to a single catchment in the Brecon Beacons (Macklin and Rumsby, ) and a series of debris flows in one valley in Snowdonia (Winchester and Chaujar, ).The Cambrian Mountains, which form the central uplands of Wales (), have yet to be studied in.

P.O. BoxWest Trenton, NJ Phone (); Fax () Thanks to NJ for hosting the DRBC website. A discharge from a mine shall include a discharge which occurs after mining operations have ceased, provided that the mining operations were conducted subsequent to January 1,under circumstances requiring a permit from the Sanitary Water Board under the provisions of section (b) of this act as it existed under the amendatory act of.

The Johnstown Flood (locally, the Great Flood of ) occurred onafter the catastrophic failure of the South Fork Dam, located on the south fork of the Little Conemaugh River, 14 miles (23 km) upstream of the town of Johnstown, dam broke after several days of extremely heavy rainfall, releasing million cubic meters of water.

Nationally, USGS surface-water data includes more thanstation years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual field measurements at installations across the Nation.

Stream restoration 1 efforts utilizing a natural-stream design approach that emph asizes working in concert with natural stream. The stream can continually adjust its channel shape and path as the amount of water passing through the channel changes The volume of water passing any point on a stream is called the discharge.

Discharge is measured in units of volume/time (m 3 /sec). Cross Sectional Shape - varies with position in the stream and discharge. For economic and hydraulic efficiency, culverts should be designed to operate with the inlet submerged during flood flows, if conditions permit.

Bridges, on the other hand, are not designed to take advantage of submergence to increase hydraulic capacity even though some are designed to be inundated under flood.

TAKE ACTION. When a flash flood WATCH is issued Be alert to signs of flash flooding and be ready to evacuate on a moment's notice. When a flash flood WARNING is issued for your area, or the moment you realize that a flash flood is imminent, act quickly to save yourself. You may have only SECONDS.

Go to higher ground Climb to safety. Get out of areas subject to flooding. Each flood discharge (y-axis) is plotted against its probability of exceedance or recurrence interval on probability paper. The points are joined to form a flood-frequency curve or exceedance curve (see Figs and ).

Even without extremely long-term records, the curves are often projected to calculate discharge for a year event. Estimate of peak flood discharge rate. The center of the South Fork dam failed catastrophically more than 3 h after overtopping began. Dam breach methods have been used by other authors to estimate the peak discharge.

The scientific literature contains several estimates of peak discharge rate for the Johnstown Flood of For planning and insurance purposes, flood hazard based on historical flood records is typically assumed to be statistically stationary.

However, there is evidence that changes in climate and land cover are altering river flows [ Kundzewicz et al., ] and that changes in stream channel cross sections are altering local channel capacity. Stream Discharge Hydrograph. This is one of the most frequently created hydrographs.

It shows the change in discharge of a stream over time. The blue line on the hydrograph above shows how the discharge of the Tioga River changed between August 29 and September 5,   Gravel-bedded streams are thought to have a characteristic meandering form bordered by a self-formed, fine-grained floodplain.

This ideal guides a multibillion-dollar stream restoration industry. We have mapped and dated many of the deposits along mid-Atlantic streams that formed the basis for this widely accepted model. These data, as well as historical maps and records, show.

Records of the Committee on Rivers and Harbors () History and Jurisdiction. Authorized early in the 48th Congress in Decemberthe committee was given jurisdiction over subjects relating to the improvements of rivers and harbors and had the responsibility of reporting the river and harbor bill, which previously had been handled by the Committee on Commerce.

With a continuous global increase in flood frequency and intensity, there is an immediate need for new science-based solutions for flood mitigation, resilience, and adaptation that can be quickly deployed in any flood-prone area.

An integral part of these solutions is the availability of river discharge measurements delivered in real time with high spatiotemporal density and over large-scale.

p) precipitation records q) newspaper accounts of previous floods r) satellite photographs taken every ten years s) discharge data from stream gauges Answer: d Section: Difficulty Level: Remember/Understand Topic: Streams and Flooding In the accompanying hydrograph for major river, a flood was caused by a single episode of heavy rainfall.

The purpose of this page is to define floodways, a commonly used term in floodplain management. Definition/Description. A "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height.A collection of related records.

Datum: A fixed starting point of a scale. Channel of a stream plus any adjacent floodplain areas that must be kept free of encroachment so that the year flood discharge can be conveyed without increasing the elevation of the year flood by more than a specified amount (1 foot in most states.The method was applied to a group of records from 42 gaging stations in Nevada with many years of no flow and with many poorly defined flood‐frequency relations.

One‐ and two‐parameter models were developed in which much of the variance in peak discharge is explained by drainage area.
