If two or more wells are constructed very close to each other such that their cones of depression intersect, they are said to interfere each other. Due to interference, yield of wells are decreased. Muskat has proposed the following formulae for computation of discharges from such interfering wells:<\/p>\n

THE HYDROLOGIC CYCLE AND WATER QUALITY<\/h2>\n

Water is one of the most abundant compounds found in nature, covering approximately three-fourths area of the earth. Inspite of this apparent abundance, several factors serve to limit the amount of water available for human use.
\nOver 97% of the total water supply is contained in the oceans and other saline bodies of water and is not readily usable for most purposes. Of the remaining 3%, a little over 2% is tied up in ice caps and glaciers and, along with atmospheric and soil moisture, is inaccessible. Thus, for general livelihood and the support of their varied technical and agricultural activities, humans must depend upon the remaining 0.62% water found on fresh water lakes, rivers and ground water supplies.\"Hydrologic<\/p>\n

Water is in a constant state of motion depicted in the hydrologic cycle as shown in figure. Atmospheric water condenses and falls to the earth as rain, snow or some other term of precipitation. On the earth\u2019s surface, water flow into streams like lakes and eventually the oceans or percolates through the soil and into aquifers than eventually the oceans, discharge into surface waters. Water in nature is most nearly pure in its evaporation state. The impurities accumulated by water throughout the hydrologic cycle and as a result of human activities may be in both suspended and dissolved form. Dissolved material consists of molecules or ions that are held by the molecular structure of water. Colloids are very small particles that technically are suspended. Size range of dissolved, colloidal and suspended substances are shown in figure.<\/p>\n
