    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. [citation needed] In North America, surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern.   Drainage basin boundaries and the main stream, as computed by watershed analysis, are shown in a map view of the topography in Fig. Fig.2 2 a. The outlet (endpoint) of the stream corresponds to one of the craters superimposed on the channel.

Relationships among streamflow, drainage basin, and channel characteristics by Michael Ying-Luen Tsang Download PDF EPUB FB2

Morphometry of drainage networks Relation of morphometric parameters and river flow. The functional relationships among various network characteristics, including the relationships between discharge on the one hand and drainage area, channel width, and length of main stem on the other, encourage the continued exploration of streamflow in relation to basin geometry.

QUANTITATIVE MODELING OF THE RELATIONSHIPS AMONG BASIN, CHANNEL AND HABITAT CHARACTERISTICS FOR CLASSIFICATION AND IMPACT ASSESSMENT CMER PROJECT Prepared for the AMBIENT MONITORING COMMITTEE Timber, Fish and m Prepared by JOHN F. ORSBORN, P.E. Department of Civil and Environmental Engineering.

Most of the precipitation that falls within the drainage area of a stream's USGS monitoring site collects in the stream and eventually flows by the monitoring site. Many factors, some listed below, determine how much of the streamflow will flow by the monitoring site. Imagine that the whole basin is covered with a big (and strong) plastic sheet.

Drainage basin BASINS, CHANNELS, AND FLOW CHARACTERISTICS OF SELECTED STREAMS IN CENTRAL PENNSYLVANIA By LUCIEN M.

BRUSH, JR. ABSTRACT The hydraulic, basin, and geologic characteristics of 16 selected streams in central Pennsylvania were measured for the purpose of studying the relations among these general characteristics andCited by: Streamflow measurements are commonly based on water level measurements that are converted to a discharge rate using a rating curve (see Fig.

).The rating curve is constructed based on a sample of streamflows measured using the (time-consuming) velocity–area method and their corresponding water level (concurrent streamflow and water level data sample is termed gauging).

1. Introduction. Source-to-sink studies focus on the drainage basin, the depositional area, and the relationship between these two domains (Sømme et al., ), and can give important insights into the erosional-depositional budgets and provide information for basin-fill assessment (Allen et al., ).To better understand the basin fill, the sedimentary successions are subdivided into.

streamflow characteristics might be estimated at any ungaged, natural- flow site from and channel characteristics book presently available long-term streamflow records.

Another purpose of the study was to determine the topographic and climatic drainage-basin characteristics most effective for explaining the site-to-site variations in streamflow. of drainage basins to basin-runoff characteristics have been described by Langbein (, p.

The topographic parameters considered important in these studies were: area, channel slope, stream pattern, average basin width, mean length of travel (channel length), and mean relief measured from gaging station.

Many stream-flow characteristics are related either directly or indirectly to topographic features. It would seem, however, that the The fact of relationship between the time distribution of discharge during a flood and the size, shape, and gradient of a drainage system Drainage-basin characteristics: Am.

Geophys. Union Trans., No. Drainage-Basin Characteristics 3 Drainage-Basin Characteristics Topographic and meteorologic characteristics of a drain-age basin affect streamflow from the basin. The characteristics that were used in this study to evaluate the drainage-area ratio method were drainage area, main channel slope, and precipita-tion.

Network Characteristics in Suburbanizing Streams WILLIAM L. GRAF Department of Geography, University of Iowa, Iowa City, Iowa Analysis of hydrologic, geomorphic, and suburbanization data from a small instrumented drainage basin near Iowa City, Iowa, indicates that channel networks are radically altered when suburban.

New hydrological insights for the region. A combination of 3–6 explanatory variables – chosen among annual rainfall, drainage area, perimeter, elevation, slope, drainage density and latitude – is sufficient to predict a range of flow metrics with a prediction R-squared ranging from 84 to 95%.The inclusion of forest or paddy percentage coverage as an additional explanatory variable led to.

The Zhanghe Reservoir in Yangtze River basin plays a key role in fulfilling the crop water requirements of the irrigation area in its downstream region. This study employs the SWAT (Soil and Water Assessment Tool) model to simulate the variations of Zhanghe Reservoir inflow.

Implication of relationships among suspended sediment size, water discharge and suspended sediment concentration: the Yellow River basin, China transportation and deposition in both drainage basin and river channel.

This is because at low discharges, the streamflow is baseflow supplied by groundwater, and the sediment it carried is the.

River - River - Streamflow and sediment yield: Rapid variations of water-surface level in river channels through time, in combination with the occurrence from time to time of overbank flow in flat-bottomed valleys, have promoted intensive study of the discharge relationships and the probability characteristics of peak flow.

Stage (depth or height of flow) measurements treat water level. A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and are no official definitions for the generic term river as.
