Drainage density is the total length of all the stream s and river s in a drainage basin divided by the total area of the drainage basin. It is a measure of how well or how poorly a watershed is drained by stream channels. It is equal to the reciprocal of the constant of channel maintenance and equal to the reciprocal of two times the length of overland flow. Drainage density depends upon both climate and physical characteristics of the drainage basin. Soil Permeability earth sciences permeability infiltration difficulty and underlying rock type affect the runoff in a watershed impermeable ground or exposed bedrock will lead to an increase in Surface runoff surface water runoff and therefore to more frequent streams. Rugged regions or those with high relief will also have a higher drainage density than other drainage basins if the other characteristics of the basin are the same. Drainage density can affect the shape of a river s hydrograph during a rain storm. Rivers that have a high drainage density will often have a more flashy hydrograph with a steep falling limb . High densities can also indicate a greater flood risk. High drainage densities also mean a high bifurcation ratio .

The Lower River Bann flows from Lough Neagh , the largest freshwater lake in the British Isles , for 60 km 35 miles , to the Barmouth between Castlerock and Portstewart , where it discharges into the sea. From the end of the last ice age, Lough Neagh has flowed along this natural valley, but a couple of constrictions controlled the flow and led to large fluctuations in the water level along the shoreline, disrupting farming activities on a large scale. The drainage and navigation system has been significantly modified twice in the last couple of centuries to increase the reliability of farmland.

As well as investigating catchment area, rainfall, and particular floods, he concluded on the causes of flooding and presented proposals for remedy with estimated costings.

Incision and drainage and clinical lancing are minor surgery surgical procedure s to release pus or pressure built up under the skin, such as from an abscess , boil , or infected paranasal sinus. It is performed by treating the area with an antiseptic , such as iodine based solution, and then making a small incision to puncture the skin using a sterilization microbiology sterile instrument such as a sharp needle, a pointed scalpel or a Lancet surgery lancet . This allows the pus fluid to escape by draining out through the incision. Good medical practice for large abdominal abscesses requires insertion of a drainage tube, preceded by insertion of a Peripherally inserted central catheter PICC line to enable readiness of treatment for possible septic shock .
