What is hydrogeological method?
Hydrogeology is the study of groundwater – it is sometimes referred to as geohydrology or groundwater hydrology. Hydrogeology deals with how water gets into the ground (recharge), how it flows in the subsurface (through aquifers) and how groundwater interacts with the surrounding soil and rock (the geology).
What is a hydrological map?
maps depicting the distribution of water on the earth’s surface, characterizing the regime of bodies of water, and making it possible to evaluate the water resources of individual land areas.
How do you determine the direction of groundwater flow?
General flow directions are determined from contour maps of the water table and potentiometric surface (Fig. 2.5), if available, or from information on water levels, boundaries, and locations of recharge and discharge areas.
What is groundwater mapping?
Groundwater Mapping is a multidisciplinary technique to characterize the occurrence, distribution, movement and quality variation of groundwater in different aquifer systems.
How is well depth measured?
Use an electric depth gauge. This is the easiest, and most common method to measure your well’s static water level. This equipment typically consists of two wires with an electronic sensor that indicates when, and at what depth, the tape has hit water. The tapes can be purchased or constructed.
How do you do a hydrogeological survey?
A basic survey comprises of the following:
- Establish the needs of the end-user regarding the location and quantity of groundwater required.
- Nearby boreholes.
- Evaluation of the quality of groundwater.
- Appraisal of the catchment area.
- Borehole construction and design recommendations.
- Assessment of risk to health or environment.
How much does a hydrogeological study cost?
Costs for professional performance of the entire WHPA delineation, inventory and planning process start at <$10,000 (spread over a period of years) for village-sized systems, or about $10,000 to $45,000 for a complicated WHPA delineation (in a Miami River Valley aquifer, for example).
Why is hydrology important?
The hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
What is surface geological map?
Geologic maps show the types and ages of rocks and younger deposits that are found at or near the Earth’s surface. This fundamental tool for earth scientists, maps show map units, faults and folds, cross sections, and other regional or local features, depending on map scale.
In which compass direction is the groundwater flowing?
Based on the contour map and groundwater flow lines, groundwater generally flows from east to west direction.
How do you read a groundwater contour map?
The ground water flow direction can be represented by an arrow drawn perpendicular to the ground water contour lines. The volume of water that flows through the aquifer over a given time period can be calculated from the velocity and cross sectional area of the aquifer.
How aquifer mapping is done?
Aquifer mapping can be defined as a scientific process, wherein a combination of geologic, geophysical, hydrologic and chemical field and laboratory analyses are applied to characterize the quantity, quality and sustainability of ground water in aquifers.
How do you map an aquifer?
Three major steps involved in aquifer mapping are data collection, post-processing and reporting.
…
Data collection:
- Exploration and collection of groundwater data.
- Field investigations, collecting information about open and bore wells.
- Geophysical investigations and characterization of groundwater reservoirs.

What is the average depth of a well?
100 feet to 800 feet deep
Typical Depth of a Water Well
The typical depth of a residential well ranges from 100 feet to 800 feet deep. Some wells are even 1,000 feet or deeper. The deeper a well is, the better the water quality.
What is a hydrogeological survey?
Hydrogeological survey involves the investigation of the subsurface hydrologic and geologic parameters in a specific area. It entails a thorough examination of the water-bearing levels of rocks as well as their filtration capacity. Furthermore, the inherent ability of these rocks to store or resist water is evaluated.
What is a hydrogeological report?
A Hydrogeological Study is an objective science-based review of the. subsurface hydrogeologic and geologic conditions in an area or location to identify development suitability and constraints. Purpose.
What is the difference between hydrology and hydrogeology?
Hydrology is the science that studies the spatial and temporal distribution and the properties of water available in the atmosphere and in the earth’s crust (rainfall, runoff, soil moisture, evapotranspiration, etc.). On the other hand, Hydrogeology is the branch of hydrology that studies groundwater.
What is an example of hydrology?
The definition of hydrology is the branch of science or geology that studies the Earth’s water. The study of how the major bodies of water have shifted, expanded and changed land masses is an example of hydrology.
What is application of hydrology?
Hydrology is an indispensable tool in planning and building hydraulic structures. Hydrology is used for city water supply design which is based on catchments area, amount of rainfall, dry period, storage capacity, runoff evaporation and transpiration.
How do you create a geological map?
The steps of geological mapping activity are:
- Make outcrop observation, and make a description of it.
- Measure the position of rocks (strike and dip), geological structure elements, and other geological elements.
- Make a record observations in a field notebook.
- Determine the outcrop location by using GPS.
How do you draw a geological map?

What is the relationship between the direction of groundwater flow and the elevation of the water table?
Using known altitudes of the water table at individual wells (A), contour maps of the water-table surface can be drawn (B), and directions of ground-water flow along the water table can be determined (C) because flow usually is approximately perpendicular to the contours.
What are the 4 zones of groundwater?
