Long-term rainfall-runoff characteristics of a small southern piedmont watershed. Few studies have reported runoff from small agricultural watersheds over sufficiently long period so that the effect of different cover types on runoff can be examined.

We analyzed yrs of monthly and annual rainfall-runoff characteristics of a small ( ha) zero-order typical Southern Piedmont watershed in southeastern United by: Endale et al.

The study was conducted in the Yangou watershed (29°16′N to 29°17′N, °42′E to °43′E), which is located in the Jiangxi Eco-Science Park of Soil and Water Conservation, 5 km southeast of De’an county in Jiangxi province ().The area studied is characterized by a subtropical humid monsoon climate zone and a long-term annual precipitation of mm.

The quantitative analysis of the watershed is important for the quantification of the channel network and to understand its geo-hydrological behaviour. Assessment of drainage network and their relative parameters have been quantitatively carried out for the Chakrar watershed of Madhya Pradesh, India, to understand the prevailing geological variation, topographic information and.

The watershed contains a naturally regenerated second-growth forest on abandoned agricultural land, typical of the Piedmont. The analysis of rainfall-runoff for a watershed can be used to predict flood. The connection between rainfall and the runoff in a watershed is influenced by the physical characteristics of the watershed [1].

The physical characteristic response of the watershed toward rainfall forming surface runoff is formulated as surface. Storm runoff is a growing concern against a background of increasing urban densification, land-use adaptation and climate change.

In this study, a storm water management model was used to analyze the hydrological and water-quality effects of rain gardens (also known as bioretention cells) as nonpoint source control solutions in low-impact development (LID) practices for an urban catchment in.

This technique has been called runoff agriculture or water harvesting; the latter is usually used to indicate water collection for domestic use. The amount of water that can be collected during a rainfall event depends on rainfall characteristics such as quantity, intensity and distribution, and on the generating area such as size.

Surface water availability does not have an effect on rain-fed agriculture, but the effect on irrigated agriculture is very high in the Southern Mediterranean region because the model assumes that water availability controls irrigation (Fig.

The Central European region also shows some sensitivity if water availability is reduced. L.J. Bracken, in Treatise on Geomorphology, Catchment hydrological response and resulting flood generation are governed by a suite of complex interactions between basin characteristics, storm properties, and antecedent wetness conditions.

This chapter links soil water movement at the plot scale to runoff production at the hillslope scale through to flood generation at the catchment scale. Urban water balance (i.e., P+I=Q+ET+ S) (Grimmond et al., ) The rates and volumes of surface runoff from urbanized watersheds are expected to be greater due to soil compaction, vegetation.

José C.B. Dubeux Jr., Lynn E. Sollenberger, in Management Strategies for Sustainable Cattle Production in Southern Pastures, Runoff. Runoff is the water discharged into surface water bodies. When rainfall is greater than soil infiltration rate, surface runoff occurs.

Factors affecting runoff include rainfall intensity, slope, soil water storage capacity, and infiltration rate [12].

This Special Issue of Water is intended to give readers an overview of the environmental effects of urban stormwater pollution and how both centralized and decentralized facilities systems are being implemented to effectively manage and treat polluted stormwater runoff to protect the water environment.

The Special Issue will consider. Runoff potentiality of a watershed was assessed based on identifying curve number (CN), soil conservation service (SCS), and functional data analysis (FDA) techniques. Daily discrete rainfall data were collected from weather stations in the study area and analyzed through lowess method for smoothing curve.

As runoff data represents a periodic pattern in each watershed, Fourier series was. LONG-TERM RAINFALL-RUNOFF CHARACTERISTICS OF A SMALL SOUTHERN PIEDMONT WATERSHED-(Proceedings) Endale, D.M., Fisher, D.S., Steiner, J.L.

Long-term rainfall-runoff characteristics of a small southern piedmont watershed. First Interagency Conference on Research in the Watersheds. Rainfall-generated floods in the Arctic are rare and seldom documented. The authors were fortunate in July to monitor such a flood on the Upper Kuparuk River in response to a h duration rainfall event that produced a watershed average in excess of 80 mm.

Atmospheric conditions prevailed that allowed moist air to move northward over areas of little or no vertical relief from the. some water-quality and quantity data were collected for storm-water runoff from small watersheds having various land uses (agricultural-rural to high-density residential) and from wet- and dry-weather sampling of the main stem of Jones Falls and selected tributaries (Regional Planning Council, written commun., ).

A study of phosphorus accumulation and mobility was conducted in eight pastures in the Georgia piedmont, USA. We compared two potential grazing treatments: strategic-grazing (STR) and continuous-grazing-with-hay-distribution (CHD) from (Baseline) to (Post-Treatment) for (1) distribution of Mehlich-1 Phosphorus (M1P) in soil and (2) dissolved reactive phosphorus (DRP) and total.

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.

Runoff ponds should be designed to hold all the runoff from the controlled drainage area in a 90th percentile wet year. This size is easily calculated from rainfall records for the district, the area (m 2), and the runoff coefficient for the surface concerned.

As the main variable in the size of the retention pond is the size of the controlled. Runoff and soil loss were continuously monitored from May to April from four erosion plots ( m × m (24 ft × 40 ft)) in CT and four plots in NT under a corn (Zea mays L. Effect of spatial scale on RC was studied for 12 runoff plots (2 m by 15 m) and three small watersheds (– ha) in the highlands of Ethiopia using a total of day.

In-situ rain water harvesting, involves the use of methods that increase the amount of water stored in the soil profile by trapping or holding the rain where it falls, and it involves small movements of rainwater as surface runoff, in order to concentrate the water where it is required.

Water harvesting retains moisture in-situ, through.A study was conducted on the impact of forest clearance on discharge from newly established Hopea odorata plantations catchment ( ha).

The stands were two years old when this study commenced in year and the data collection was carried out for two years. The forested catchment (C3) was clear-cut during the preparation of the forest plantation and catchment C1 was left undisturbed.Surface Water Characteristics.

Streams flow relatively slowly to the Atlantic Ocean or the Delaware Bay. Natural lakes are rare to non-existent. Small water impoundments are common along the upper reaches of streams. Bogs, swamps, and salt marshes exist along the Atlantic Coast.

Bogs tend to be very acidic, mainly in the soils of the pine barrens.
