Drainage Basin As A Hydrological Unit Pdf Chapter5 hydrology class free download as pdf file (.pdf), text file (.txt) or view presentation slides online. runoff occurs when precipitation exceeds the infiltration capacity of soils. If a basin or catchment area contains more than one gauge, the computation of average precipitation or rainfall depth may be done by the following methods.
Hydrology Chapter 5 Pdf Drainage Basin Flood The runoff curve numbers developed in tr 55 are based upon watershed characteristics including soil type, type and amount of plant cover, amount of impervious area, runoff interception, and surface storage. Basin configurations shall be consistent with surface runoff patterns. for example, the roof and lawn areas of residential neighborhoods can be combined and considered one basin when the roof runoff travels through the lawn before getting to the streets. Under this process the water becomes available for its distribution (surface and sub surface) and circulation on the above and below the earth surface. it mostly takes place in the form of liquid (rainfall) and very little in solid form (snow, sleet, hail fog etc.). 1.2. drainage basin: a drainage basin is any area of land where precipitation accumulates and flows into a common outlet, like a river, bay, or other body of water.

Section 1. the drainage basin drainage basins overview of surface hydrology i. introduction a. terminology. There are three major types of runoff depending on the source: surface flow, interflow, and base flow. surface flow : surface flow is water that has remained on the surface and moves as overland or channel flow. Plot the ordinates of the unit hydrograph against time since the beginning of direct runoff, which is the unit hydrograph for the basin for the duration of the storm. Stormwater collection systems must be designed to provide adequate surface drainage while at the same time meeting other stormwater management goals such as water quality, streambank channel protection, habitat protection and groundwater recharge.
