Compound flooding conditions present a significant challenge for civil engineers in their pursuit to design for and maintain the integrity of a structure’s entire life cycle. Coupled with non-stationary processes due to a changing climate and land use change, risk is a moving target. Through the support of ASCE’s Task Committee on Compound Flooding, the Hydroclimatology Engineering Adaptation (HYDEA) sub-committee is developing a Manual of Practice (MOP) to provide a synthesis of available tools and methods of best practice for civil engineers designing for compound flooding conditions. This paper presents a primer for practicing civil engineers on this work. Hydrodynamic …
Design Aspects Of Deep Water Distribution Shafts, Navid Allahverdi, V. Nasr
Design Aspects Of Deep Water Distribution Shafts, Navid Allahverdi, V. Nasr
Publications and Research
This paper covers aspects of planning and designing of deep shafts with reference to two water distribution shafts under construction in New York City. The new shafts will be sunk into soil and rock to a depth to connect to existing Queens-Brooklyn tunnel section of City Tunnel No. 3 (CT3). The inside diameter of the upper parts of both shafts is 14.9 meter. Artificial ground freezing is specified as preferred method of excavation support for the entire stretch in soil. Excavation in competent rock will be performed using drill and blast technique preceded by a pre-excavation grouting program. Membrane waterproofing …
