Drainage density relates to the storage and runoff terms. Drainage density relates to the efficiency by which water is carried over the landscape. Water is carried through channels much faster than over hillslopes, as saturated overland flow is slower due to being thinned out and obstructed by vegetation or pores in the ground. [7]
Fourmile Creek Sub-watershed consists of the 11.93-square-mile (30.9 km 2) drainage of the 8-mile-long (13 km) Fourmile Creek. The creek's mouth opens to Lake Erie about one-half mile north of Pennsylvania Route 5 at Water Street. It draws its name from its location four miles (6 km) east of the center of Erie, Pennsylvania.
Meadow Brook is a tributary of the Lackawanna River in Lackawanna County, Pennsylvania, in the United States. It is approximately 2.0 miles (3.2 km) long and flows through Dunmore and Scranton. [1] The watershed of the stream has an area of 2.43 square miles (6.3 km 2), though it used to be considerably larger. It is designated as a Coldwater ...
The Susquehanna River is in the U.S. States of Maryland, Pennsylvania and New York.As of 2000, the Susquehanna drainage basin population was 3,968,635. Its total area is 27,486 square miles (71,188 km 2), and in 2000 612 square miles (1,585 km 2) were developed, 8,041 square miles (20,826 km 2) were used for agriculture, 18,181 square miles (47,089 km 2) were forested, 27,486 square miles ...
Debris from vegetation such as leaf cover can also increase the infiltration rate by protecting the soils from intense precipitation events. In semi-arid savannas and grasslands, the infiltration rate of a particular soil depends on the percentage of the ground covered by litter, and the basal cover of perennial grass tufts.
The notions of time, uplift, slope and drainage density evolution in the erosion cycle have been criticized. [21] Further the validity of some whole concepts associated with the cycle of erosion have been questioned including stream grade, [21] slope decline, [D] base level [21] and most of all that of peneplains. [21] [E]
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...
