A detailed sketch of a gravity dam is shown in Fig. 13.1. All the predominant forces that act on the dam have been shown in the figure itself. The forces that act on the dam are the following: 1. Weight of the dam 2. Horizontal hydrostatic pressure due to water 3. Uplift pressure due to […]

Properties of an Aquifer (With Diagram) | Geography
Article shared by : 
Two properties of an aquifer material related to its storage function are its porosity and specific yield. Porosity is the ratio of the volume of voids or pores in a soil mass to its total volume. Shape, size and packing of the grains affect the porosity of granular material. The grain size distribution of the […]
How to Calculate the Velocity of Ground Water Flow? | Geography
Article shared by :
Ground water moves from levels of higher energy to levels of lower energy, its energy being essentially the result of elevation and pressure, the velocity heads being neglected since the flow is essentially laminar. The velocity is very small in the laminar range—of the order of 1 cm/sec—and the Reynolds number (Re) for ground water […]
