This analysis may be sufficient to obtain a rough impression of the groundwater behavior, but it can also serve to do a sensitivity analysis to answer the question: which factors have a great influence and which have less influence. With such information one may direct the efforts of investigation more to the influential factors.
These techniques may be used in the identification of flood dynamics, [22] [23] storm characterization, [24] [25] and groundwater flow in karst systems. [26] Regression analysis is used in hydrology to determine whether a relationship may exist between independent and dependent variables.
GSSHA (Gridded Surface/Subsurface Hydrologic Analysis) [1] is a two-dimensional, physically based watershed model developed by the Engineer Research and Development Center of the United States Army Corps of Engineers. It simulates surface water and groundwater hydrology, erosion and sediment transport.
Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering , hydrogeology or soil mechanics as a first check for problems of flow under hydraulic structures like dams or sheet pile walls.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...

The Solinst Waterloo Multilevel groundwater monitoring system is a modular MLS designed to collect groundwater data from multiple depths within a single borehole via a series of monitoring ports positioned at specific intervals along 2-inch ID Schedule 80 PVC casing. The various monitoring ports can be connected to a combination of: sampling ...
shallow ground water/seepage; and; other types of geologic constraints. An engineering geologist or geophysicist may be called upon to evaluate the excavatability (i.e. rippability) of earth (rock) materials to assess the need for pre-blasting during earthwork construction, as well as associated impacts due to vibration during blasting on projects.
