Water Level Contour

Geo-hydrology and groundwater exploration manner to pick out and to find the zone of recharge of groundwater in a precise river basin or a catchment .water level contour traces (or waft traces) are much like topographic strains on a map. They fully represent "elevations" in the subsurface. Water table contour lines can be used to inform which manner groundwater will glide in a given region. Plenty of wells are drilled and the hydraulic head is measured in each one. Water desk contours are drawn that be a part of areas of identical head .The ones water table contours lines are also called equipotential strains. Bear in mind: groundwater usually movements from a place of the higher hydraulic head to an area of decrease hydraulic head, and perpendicular to equipotential traces. In our challenge, we put into effect concept of water table contour map and geohydrological studies on Krishnagiri using GIS software program which plays the essential position in contemporary technology.

This paper presents information on the behavior of the Logaras karst spring, which is located 2.5 km north of Skortsinou village of the Municipality of Falaesia. This spring discharges the water table hosted in the carbonate rocks located in the area among Skortsinou, Petrina, Soulario and Voutsaras Villages. This area consists of thin-platy limestones of Pindos Unit that overlay the “First Flysch” formation, which is the stratigraphic bedrock of the aforementioned limestones. Aiming at the accurate determination of the boundaries of the spring’s hydrological basin, the geological map of I.G.M.E., sheet “Megalopolis” (Papadopoulos 1997 και Luettig & Vingen 1964) was re-examined. The geological and tectonic observations that derived from this process contributed to the analysis of the spring’s mechanical operation. This led to the conclusion Logaras Spring is a contact spring. Furthermore, discharge measurements of the spring took place for the period from 24/6/2006 to 26/10/2007 and the relevant hydrograph was drawn, from which the recession coefficient was calculated. More particularly, the spring’s recession coefficient for the hydrological years 2005 – 2006 and 2006 – 2007 is 1,9·10-3 and 4,3·10-3 respectively, while the dynamic volume reach 5,4 • 106 m3 and 1,7 • 106 m3 respectively.
