Hydraulic conductivity The rate of flow of water through a unit cross sectional area of an aquifer, at a unit hydraulic gradient. In US units the rate of flow is in gallons per day per square foot of cross sectional area; in SI units hydraulic conductivity is usually quoted in m 3 per day per m 2. Units are frequently shortened to metres per ...
The system was renamed the McAlpine Locks and Dam in 1960 in honor of William McAlpine, who was the only civilian to have ever served as district engineer for the Corps of Louisville. At present, the normal pool elevation is 420 feet (130 m) above sea level and the drainage area above the dam is 91,170 square miles (236,000 km 2 ).
The Louisville Water Company has been in operation since 1860. First known as "The Water Works", the company served water to 512 customers. [1] Water delivery began on 6 October 1860. [2] In 1879, the Crescent Hill Reservoir, developed by Charles Hermany and with a capacity of 100 million gallon, opened to retain more mud from the water ...
Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations. They include the natural and man-made chemical , biological and microbiological characteristics of rivers , lakes and ground-waters , the ways they are measured and the ways that they ...
A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation , the water pressure can be boosted by means of a fire pump .
The water at a tree's base is another potential hazard. Additives and fertilizers, such as xylitol and aspirin, are harmful to cats if consumed. This could lead to an upset stomach or, ...

This list is arranged by drainage basin, with respective tributaries indented under each larger stream's name. All rivers in Kentucky flow to the Mississippi River, nearly all by virtue of flowing to its major tributary, the Ohio River.
