Book review: The Physical Properties of Minor Aquifers in England and Wales Article in The Environmentalist 22(2) June with 19 Reads How we measure 'reads'. Aquifer properties. Aquifer properties are the hydraulic characteristics of aquifers, which are used to describe an aquifer and understand how groundwater in the aquifer exists and behaves. Aquifer properties are the most important way to describe the hydrogeology of an aquifer.   Summary.

Aquifer Properties. In the previous section, you’ve learned about the different types of aquifers, and the basic characteristics that define an aquifer – namely the ability to store and transmit water. 1 Properties of aquifers Aquifer materials Both consolidated and unconsolidated geological materials are important as aquifers. Of the consolidated materials (ie. bedrock), sedimentary rocks are the most important because they tend to have the highest porosities and permeabilities.   Aquifer characterization is broadly defined as processes by which the three-dimensional structure, hydraulic and transport properties, and chemistry of aquifers are evaluated. Aquifer characterization provides the foundation for groundwater modeling, which is ubiquitously used to evaluate sedimentary aquifers. What are the different kinds of aquifers? Fundamentally, the ability to store and transmit water are the two key ingredients that make a subsurface geological formation useful as an aquifer. In Module , we will explore the detailed physical properties of rocks and sediments that ultimately affect the storage and movement of groundwater.

Scotland’s bedrock geology was classified into broad aquifer groups which have distinctly different physical aquifer properties and/or controls on natural groundwater chemistry. The aquifer groups are shown in Figure 5 and listed in Table 1. The characteristics of the aquifers are described in the Aquifer characteristics article.   GIS techniques used to estimate the extent of urbanisation and suburbanisation of land overlying locally and nationally important aquifers in England and Wales show that: 1. About 10 km 2 of the aquifer outcrop/subcrop lies beneath built .   There are two general types of aquifers: confined and unconfined. Confined aquifers have a layer of impenetrable rock or clay above them, while unconfined aquifers lie below a permeable layer of soil. Many different types of sediments and rocks can form aquifers, including gravel, sandstone, conglomerates, and fractured limestone. Aquifers are sometimes categorized according to the type . The principal aquifers of the UK are found in the lowlands of England. The most important are the Chalk, the Permo-Triassic sandstones, the Jurassic limestones and the Lower Greensand. They occur within the section of the geological sequence referred to as the Younger Cover, which ranges in age from the Permian to the Quaternary. Aquifers.
