direct runoff

These items direct runoff away from the foundation and minimize erosion caused by the water's impact.

That said, the process of separating "baseflow" from "direct runoff" is an inexact science.

It can be used with a unit hydrograph to derive the runoff rate from the direct runoff by convolution.

It is widely used and is an efficient method for determining the approximate amount of direct runoff from a rainfall event in a particular area.

Several processes can be identified using the tritium data from the rivers: direct runoff and outflow of water from groundwater reservoirs.

Excessive application or application to sodden land or insufficient land area can result in direct runoff to watercourses, with the potential for causing severe pollution.

Clean the gutters and downspouts and make sure that splash blocks or other devices are in place to direct runoff from the roof away from the foundation.

Indeed, it is a function of the way the region developed its storm system, a network of concrete waterways designed to avert flooding by directing runoff to the ocean.

Nearby Gridley Park, in an adjacent direct runoff zone to the east, was named Cascade Park when the city was laid out in the late 18th century.

The problem was then complicated because of a previous decision by Con Ed intended to minimize the spread of contamination: the drain directs runoff into the reactor building for treatment.

As a UH is applicable only to the direct runoff component of a hydrograph (i.e., surface runoff), a separate determination of the baseflow component is required.

The runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess.

Erie International Airport is located in the largest of these direct runoff zones, west of the City of Erie, between Walnut Creek and Cascade Creek sub-watersheds.

The landfill has "old tide gates which direct street water runoff into the Hudson River, except during high tides, when the gates close and direct runoff in the beleaguered sewer system," the letter said.

The separation of base flow from direct runoff can be an important first step in developing rainfall-runoff models for a watershed of interest - for example, in developing and applying unit hydrographs as described below.

At US 20 the sub-watershed narrows to the area between Ash Street and Parade Street, with Mill Creek Sub-watershed to the west and a direct runoff zone to the east.

Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or ground-water runoff.

The separation of baseflow from direct runoff in a hydrograph is often of interest to hydrologists, planners, and engineers, as it aids in determining the influence of different hydrologic processes on discharge from the subject catchment.

It can be defined as the direct runoff hydrograph (DRH) resulting from one unit (e.g., one cm or one inch) of effective rainfall occurring uniformly over that watershed at a uniform rate over a unit period of time.

This watershed, which covers 65 km, consists of lands in the City of Erie and two neighboring townships which surround three direct runoff zones, including Presque Isle State Park, and two sub-watersheds, which all feed into Presque Isle Bay.

Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of various land use, water use, weather, and climate conditions and changes.

Lake Erie Watershed is a major drainage catchment in northwestern Pennsylvania, consisting of lands with direct runoff and sub-watersheds with waterways that flow into Lake Erie and Presque Isle Bay from Crawford and Erie counties, as well as from New York.
