Hydrogeologique research is an assessment of the subsurface geologic and hydrologic parameters in any particular location. The data acquired from such a study can be used to create a hydrogeological mapping. It encompasses a comprehensive examination of various liquid layers of rocks along with their filtering potential. Moreover, the intrinsic potential of these materials to hoard or repel water is assessed. The strength of the water flowing through fractures or pores is measured, as well as the pressure, kind, and quality of the subsurface water.
To estimate the subsurface level of water, hydrogeological research is conducted. Before digging a bore well, hydrogeological research is carried out to assess the purity and amount of water accessible at a given location. Underground water is popular as a greater source of water supply to freshwater. Following are some of the reasons behind this:
- Contamination is less likely, when it is at least 20 meters far from sanitary activity
- Water purifies itself naturally, as it passes over sands and stone
- Borewells are kept closed, which reduces the risk of infiltration
- The temperature of water at the subterranean level is at a pleasant level, irrespective of seasonal fluctuations
- Due to the water sources placed at a relatively deeper level in the summer, there are more odds of water availability
Components of hydrogeological research
Hydrogeological research can be simple or comprehensive. The following are the components of a basic survey:
- Determine the end-requirements users for the area and amount of groundwater necessary
- Boreholes in the area
- The water quality is assessed
- An assessment of the river catchment
- Guidelines for borehole design and building
- Risk assessment for health or the environment
- The volume of water that is expected to be extracted from a specific place
Thorough hydrogeological research examined a few more characteristics, such as establishing the existence of aquifers, assessing the catchment’s risk, and analyzing the water source, particularly for issues regarding pathways. The hydraulic parameters of the aquifers, as well as the direction and rate of groundwater flow, are all validated.
Groundwater is a sustainable alternative that could potentially address a water problem in specific locations in the current world scenario when pure, unpolluted water is scarce. However, determining the amount and quality of available groundwater at the needed location might be difficult. Groundwater sources can be identified using hydrogeological survey techniques, as well as the expected yield and quality of the water.
