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.
The curve number can be adjusted by factors to , where factors are less than 1 (reduce and potential runoff), while factor are greater than 1 (increase and potential runoff). The AMC factors can be looked up in the reference table below.
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 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 ...
Water supply networks are part of the master planning of communities, counties, and municipalities. Their planning and design requires the expertise of city planners and civil engineers , who must consider many factors, such as location, current demand, future growth, leakage, pressure, pipe size, pressure loss, fire fighting flows, etc ...
A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. 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 ...
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 ...
