Abstract: This investigation deals with a chemical stabilization program of expansive Esna shale, which widely distributed on the surface at the arid region along both West and East of Qena governorate, Egypt. Chemical stabilization program was applied to improve the geotechnical properties of the studied Esna expansive shale using both lime and cement kiln dust (CKD, as by product). Optimum-lime and -cement kiln dust (CKD) contents were measured using pH test according to Eades and Grimm method. Geotechnical tests of both natural and treated Esna shale samples as free swelling, ultrasonic velocity (Vp), and unconfined compressive strength (qu) were carried out. The results showed that the geotechnical properties of the studied expansive Esna shale samples mixed with CKD and/or lime were improved and stabilized. Also the results indicated that curing time increase from 7 to 90 days having a great influence on the improvement of the geotechnical behavior of the studied expansive Esna shale sample

Author(s): K C PATRA
Abstract: our society gets huge benefits from the water storage dams, but the consequences are devastating if a dam fails. It causes extensive damage to the life and properties mostly due to short warning time. Important factors governing failure studies are the breach parameters that help to quantify the risk associated with dam break floods. Many empirical equations have been developed for predicting the breaching parameters associated with peak outflow and these equations are generally developed by regression analysis from the record of dam failure data. In the present work, a hypothetical failure of dam is modelled using MIKE 11. The required inputs in terms of PMF, river cross sections, area-elevation-capacity curves, Stage-Discharge data and dam specifications are provided for modelling. Towards this, data from Sarabgarh dam project in Orissa is used to model the breach parameters and propagation of flood waves in the downstream reaches using Mike 11 and other software. The flood hydrograp
