In this article we will discuss about the main types of spillways used to handle surplus water. 1. Overflow or Ogee Type Spillway: This spillway consists of a control weir whose shape is ogee or S-shaped. The shape of the ogee spillway conforms to the profile of lower nappe of water, falling from a sharp […]

Unsteady Radial Flow in an Unconfined Aquifer | Ground Water
Article shared by : 
The Theis equations are based on the assumption that the water is released from storage in the aquifer in immediate response to the decline in the water table. In unconfined aquifers, gravity drainage may not be immediate, particularly in fine grained formations and with stratifications of slow yielding materials. When a well is pumped in […]
