Drainage Basins, Channels, and Flow Characteristics of Selected Streams in Central Pennsylvania By LUCIEN M. BRUSH, JR. PHYSIOGRAPHIC AND HYDRAULIC STUDIES OF RIVERS GEOLOGICAL SURVEY PROFESSIONAL PAPER F A study of the influence of the geologic character of drainage basins upon the hydraulic. A retention basin should generally not be considered for contributing drainage areas of less than 10 acres. Critical concern is the presence of adequate baseflow to the pond. Should the pond become dry or stagnant, problems such as algae blooms and undesirable odors will arise. Regardless of drainage area, all proposed retention basins.

The objective of surface drainage is to improve crop growth conditions by providing timely removal of excess water remaining at or near the ground surface before the crops are damaged. Surface drainage is also needed to guarantee soil workability and trafficability, so preventing delays in soil preparation operations and harvesting, respectively.
All rivers receive a water supply and the area of land this comes from is known as a drainage boundaries of the basin are known as the drainage divide or watershed and will usually be marked by areas of higher land. Drainage basins have many different characteristics that influence how quickly or slowly the main river within them responds to a period of intense rainfall, these are. Drainage Basin or River Basins. A river drains the water collected from a specific area, which is called its ‘catchment area’. An area drained by a river and its tributaries is called a drainage boundary line separating one drainage basin from the other is known as the watershed.

A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. Watersheds can be as small as a footprint or large enough to encompass all the land that drains water into rivers that drain into Chesapeake Bay, where it enters the Atlantic Ocean.
Drainage basins of the principal oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans. Ocean basins. The following is a list of the major ocean basins: About % of the world's land drains to the Atlantic Ocean.
 In North America, surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern. Drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams.
For example, the total area drained by the Mississippi River constitutes its drainage basin, whereas that part of the Mississippi River drained by the Ohio River is the Ohio’s drainage. both of these basins ultimately drain to "A".
Ridges 2 and 3 separate basins that do not drain to "A". Thus, we find that ridge 1 marks the eastern side of the drainage basin. Tracing the rest of the perimeter is now a matter of choosing the correct ridges (Figure 1c).
Figure 1: Delineating a drainage basin perimeter. Area (A b. smaller watersheds called sub-basins. Each tributary contributes to overall streamflow for the entire basin. Oregon has 20 major river basins (see Figure 4.) All watersheds have an aquatic (or water) area, a riparian area, and an upland area.
Aquatic areas include standing waters like ponds, lakes, wetlands, bogs and running surface waters such. The drainage area for a river basin is measured in a horizontal plane enclosed by the drainage divide outlining the basin. In some cases river basins may have non-contributing sub-basins, or commonly called enclosed basins, where the runoff stays within the basin and not contributing to the larger basin surrounding the enclosed basin.
The definition of a small drainage basin as it will be understood throughout this paper is: an area bounded by topographic highs, parts being occupied by an impounded body oj surface water or by the outlet of a relatively 1 low order stream and having similar physio- graphic conditions over the whole of its surface.
Pond Drain – A pipe or other structure used to drain a permanent pool within a specified time period. Principal Spillway – The primary pipe or weir that carries baseflow and storm flow through the embankment.
Riser – A vertical pipe which extends from the. Benefits of drainage in relation to healthy soil and plant life Surface Drainage Benefits that occur due to the controlled removal of surface water by surface drainage systems are: 1. Erosion control.
Removal of surface water. Excess rain or irrigation water will naturally flow to areas of lower elevation. The maximum water surface elevation during the year, hour design storm will be and small storms, and they are used in this example.

It is not clear when the significance of the drainage basin was first appreciated, but in the 18th century Pierre Perrault calculated for the basin of the River Seine in France that.

All of the water that enters a river channel and eventually flows out of the drainage. Drainage water can be disposed directly to open surface water bodies, e.g., rivers, lakes, outfall drains, seas or oceans.
Wetlands, evaporation ponds and solar evaporators are used as discharge points where there is no direct outlet to one of the open surface water bodies mentioned above. The Drainage Basin A drainage basin, or watershed, is “the area enclosed by a topographic divide such that surface runoff drains by gravity into a river, lake, or other water body” (WSC ).
Drainage basins are often described as the area that contributes flow. ter the storm water drain. The second method is to slow down or detain the flow of large quantities of storm water so that the sediment settles out before reaching the storm drain.
This is accomplished by using some type of storm water detention measure (e.g., dry extended detention basins, wet detention ponds, sediment forebay ponds, etc.). Basins whose outlets have been designed to detain stormwater runoff for some minimum time to prevent downstream flooding. Provide quantity control, mowed regularly with concrete low-flow channels, dry except during and immediately following a storm event (typically 48 hours).
Basins can also treat stormwater runoff through settling of particles. The topography of drainage basins is a sensibly permanent characteristic which influences mainly the concentration or time distribution of the discharge from a drainage basin.
River systems differ in their efficiency as agencies for collecting and conducting water. In some systems, surface waters are quickly assembled, and the dis. A stream is a body of flowing surface water of any size, ranging from a tiny trickle to a mighty river. The area from which the water flows to form a stream is known as its drainage of the precipitation (rain or snow) that falls within a drainage basin eventually flows into its stream, unless some of that water is able to cross into an adjacent drainage basin via groundwater flow.

The term used for water that hits the ground and moves across the surface before coming in contact with a stream The meaning of drainage basin To learn more about drainage basins, you can.Position the retention pond at a strategic low point in the area it will draw from.
Gravity will be your best ally for speeding away runoff during wet times, so you'll want to put the pond in a spot that receives the full measure of that benefit.small basins and to include more data on lag time changes which result from land disturbance, in particular, urbanization.
In this regard, the study of small basins is important. The land plan- ner may be interested in the hydro- logic effects in a basin the size of a housing development or even a single house.
