Groundwater and surface water are two major components of the hydrologic cycle, which describes how water circulates between different reservoirs on Earth. Groundwater is the water that exists below the land surface in pores and fractures of rocks and sediments. Surface water is the water that flows over or collects on the land surface in streams, rivers, lakes, wetlands, reservoirs, etc.
Groundwater and surface water have many differences and similarities in terms of their formation, flow, properties, measurement, monitoring, management, challenges, opportunities, etc. They also interact with each other in various ways, affecting their quantity and quality. In this article, we will explore these aspects of ground and surface water hydrology in more detail. We will also introduce some books on this topic that can be accessed online or offline in pdf file format.
Groundwater Hydrology
Groundwater forms when precipitation infiltrates into the soil and reaches the saturated zone where all pores and fractures are filled with water. The upper boundary of this zone is called the water table. The rate of infiltration depends on several factors such as soil type, land use, vegetation cover, slope, etc.
Groundwater flows from areas of high hydraulic head (pressure) to areas of low hydraulic head under the influence of gravity. The hydraulic head is determined by the elevation of the water table and the hydraulic potential of the aquifer. An aquifer is a geological formation that can store and transmit significant amounts of water. Aquifers can be classified into two main types: confined and unconfined. A confined aquifer is bounded by impermeable layers above and below, while an unconfined aquifer is only bounded by an impermeable layer below.
The properties of an aquifer that affect its ability to store and transmit water are porosity, permeability, storativity, and transmissivity. Porosity is the ratio of the volume of voids to the total volume of the aquifer. Permeability is the measure of how easily water can flow through the aquifer. Storativity is the ratio of the volume of water released or taken in by the aquifer per unit area per unit change in hydraulic head. Transmissivity is the product of permeability and aquifer thickness.
Groundwater can be measured and monitored using various methods and instruments such as wells, piezometers, boreholes, springs, seepages, etc. Wells are artificial openings that allow access to groundwater for extraction or observation. Piezometers are devices that measure the hydraulic head at a specific point in the aquifer. Boreholes are holes drilled into the ground for exploration or sampling purposes. Springs are natural outlets where groundwater emerges on the land surface. Seepages are locations where groundwater leaks out of the aquifer into surface water bodies or other aquifers.
Groundwater management involves planning, developing, allocating, and regulating the use of groundwater resources for various purposes such as domestic, agricultural, industrial, environmental, etc. Groundwater management faces many challenges and opportunities such as overexploitation, contamination, depletion, recharge, conjunctive use, artificial recharge, etc. Overexploitation occurs when groundwater withdrawal exceeds natural recharge, leading to lowering of the water table and reduction of groundwater storage. Contamination occurs when pollutants enter the groundwater system from natural or anthropogenic sources, affecting its quality and suitability for use. Depletion occurs when groundwater resources are not replenished sufficiently by natural or artificial means, resulting in irreversible loss of water and land subsidence. Recharge is the process by which water is added to the groundwater system from precipitation, surface water infiltration, irrigation return flow, etc. Conjunctive use is the integrated use of both groundwater and surface water resources to optimize their availability and quality. Artificial recharge is the deliberate introduction of water into the groundwater system to enhance its storage and quality.
Surface Water Hydrology
Surface water forms when precipitation falls on the land surface and does not infiltrate into the ground or evaporate into the atmosphere. Surface water flows over or collects on the land surface in various forms such as streams, rivers, lakes, wetlands, reservoirs, etc.
The main types and properties of surface water bodies are determined by their origin, location, shape, size, depth, volume, area, slope, velocity, discharge, etc. Streams are linear features that carry water from higher to lower elevations along a defined channel. Rivers are larger streams that drain a large area of land and have multiple tributaries and branches. Lakes are enclosed basins that hold water for a long time and have no or limited outflow. Wetlands are areas that are saturated with water for most or all of the year and support a variety of aquatic plants and animals. Reservoirs are artificial lakes that are created by constructing dams across rivers or streams for storing water for various purposes.
Surface water can be measured and monitored using various methods and instruments such as gauges, meters, sensors, satellites, etc. Gauges are devices that record the water level or stage at a specific point in a surface water body. Meters are devices that measure the flow rate or velocity of water at a specific point in a surface water body. Sensors are devices that measure various physical, chemical, or biological parameters of water such as temperature, pH, dissolved oxygen, turbidity, etc. Satellites are spacecraft that orbit around Earth and capture images or data of surface water bodies using remote sensing techniques.
Surface water management involves planning, developing, allocating, and regulating the use of surface water resources for various purposes such as domestic, agricultural, industrial, environmental, etc. Surface water management faces many challenges and opportunities such as floods, droughts, pollution, erosion, sedimentation, restoration, conservation, etc. Floods occur when surface water overflows its normal boundaries, causing damage to life and property. Droughts occur when surface water availability is below normal levels for a prolonged period of time, affecting various sectors and activities. or anthropogenic sources, affecting its quality and suitability for use. Erosion occurs when surface water removes soil and rock from the land surface, altering its shape and structure. Sedimentation occurs when surface water deposits soil and rock particles on the bottom or along the banks of surface water bodies, affecting their capacity and ecology. Restoration is the process of restoring the natural functions and values of degraded surface water bodies by implementing various measures such as revegetation, reconnection, removal of barriers, etc. Conservation is the process of protecting and preserving the existing functions and values of surface water bodies by implementing various measures such as regulation, education, incentives, etc.
Ground And Surface Water Interactions
Groundwater and surface water interact with each other in various ways, depending on their relative positions, pressures, and gradients. Groundwater can discharge into surface water bodies as baseflow, springs, seepages, etc., providing a source of water and influencing their hydrology and ecology. Surface water can recharge groundwater by infiltrating through the streambed or the bank, providing a sink of water and influencing its hydrology and quality.
The main factors that affect the interactions between groundwater and surface water are geology, topography, climate, land use, human activities, etc. Geology determines the type and distribution of aquifers and surface water bodies, as well as their hydraulic properties and connectivity. Topography determines the elevation and slope of the land surface and the water table, as well as their spatial variations. Climate determines the amount and timing of precipitation and evaporation, as well as their spatial and temporal variations. Land use determines the type and intensity of vegetation cover and soil management, as well as their impacts on infiltration and runoff. Human activities determine the type and extent of groundwater and surface water extraction and diversion, as well as their impacts on quantity and quality.
The interactions between groundwater and surface water can be modeled and predicted using various methods and tools such as analytical solutions, numerical models, empirical equations, etc. Analytical solutions are mathematical expressions that describe the relationships between groundwater and surface water variables under simplified assumptions and conditions. Numerical models are computer programs that simulate the groundwater and surface water systems using discrete representations of space and time. Empirical equations are formulas that relate groundwater and surface water variables based on observed data and statistical analysis.
The interactions between groundwater and surface water have many benefits and risks for both systems. Some of the benefits are: maintaining baseflow and streamflow during dry periods, enhancing water quality by dilution or attenuation of pollutants, supporting aquatic habitats and biodiversity by providing thermal stability or refuge, increasing water availability by conjunctive use or artificial recharge, etc. Some of the risks are: lowering or raising the water table or the stream stage by excessive extraction or diversion, degrading water quality by contamination or salinization, threatening aquatic habitats and biodiversity by altering flow regimes or temperature regimes, reducing water availability by depletion or evaporation, etc.
