WebThe standard approach is graphical. The elevation at B is between the elevations at A and C, so a contour passing through B (i.e., the 2700-ft contour) must cross the line segment AC. By the definition of strike, the direction of this contour is the strike of the unconformity surface. Thus the first step is to draw this contour (Fig. 2).

WebGroundwater level terminology. Groundwater level is a term that is used in a relatively loose way, normally referring to the level, either below ground or above ordnance datum, at which soil or rock is saturated. This is also referred to as the water table and represents the top of the saturated zone. Above the water table lies the unsaturated ... WebTopographic relief in the study area ranges from 0 to nearly 300 ft and is probably the primary factor affecting the potentiometric surface. Based on limited data, the average depth to water was about 20 ft on the northwestern and western sides of the bay and 8 ft on the southern and eastern sides. The groundwater level in a confined aquifer is more properly described as a potentiometric surface, and represents the theoretical level to which water would rise if the confining layer were not present. See more A more formal term is rest water level (RWL) which implies the water level in a borehole that has not been recently pumped, nor affected by nearby pumping. A pumped water level (PWL) refers to a water level measured … See more Perched water tables occur when there are lenses of impermeable material in a rock that is otherwise permeable. These allow small localised water tables to develop over the lenses, which can overlay a regional water table in … See more Confined aquifers occur when a layer of impermeable rock or soil overlies an aquifer that is fully saturated, allowing the water within the aquifer to be pressurised. The groundwater level … See more The term artesian is used to describe areas where the piezometric head in a confined aquifer is above the ground surface.

WebDrawdown: The vertical distance groundwater elevation is lowered, due to the removal of groundwater. The distance between the static water level and the surface of the cone of depression. Flowing Artesian Well: When the top of a well in a confined aquifer is below the potentiometric surface, water will flow out of the well under pressure. Web20 Apr 2024 · When the water-level data are mapped using elevation contours, the result is known as the potentiometric surface of that aquifer. Although similar in concept to the water table, the potentiometric surface is an imaginary surface that indicates approximately how high water would rise in a well developed at any given place in the aquifer.
