conjunctive use of ground and surface water can increase reliability of the water supply by providing independent sources. in this study, corrected utility-efficient pro-gramming that allows for more than one seasonal irrigation depth for each crop was used to determine the amount of utility maximizing investment in the well capacity for conjunctive use. results showed that optimum investment a...

ground settlement due to the shallow tunneling in urban areas can have considerable implications for aboveground civilinfrastructures. engineering geological characteristics of the tunnel host ground including geotechnical parameters of surrounding soil,groundwater situation, and in situ stress condition are amongst the most important factors affecting settlement. in this research, groundsettle...

Fitting a Gaussian curve to real settlement data is of practical use because the parameters that describe the curve, namely volume loss, maximum settlement and trough width, are conceptually easy to understand and can be compared at different locations and for different tunnel sizes, depths and construction methods. Where the magnitude of surface settlements is small, it can be difficult to obt...

We utilize a Monte Carlo simulation scheme based on the bond fluctuation model to simulate settlement of adhesive particles onto sinusoidally corrugated substrates. The particles are composed of a hard inner core with either an effective potential shell or a "soft" adhesive shell made of flexible arms attached to the particle surface. These chains adhere via either the effective potential shell...

The warming of high latitudes climate is enhancing the degradation ground-ice and inducing important landscape changes across Arctic. This new Arctic state affects geomorphological dynamics, hydrology, ecosystems, poses challenges to stability infrastructure livelihoods communities. study focuses on hamlet Paulatuk within Inuvialuit Settlement Region Amundsen Gulf, south Darnley Bay, in norther...

a r t i c l e i n f o Keywords: Crepidula fornicata Habitat association Larval settlement Microhabitat Post-settlement mortality Recruitment Habitat-specific distributions of marine benthic invertebrates can be caused by several processes acting prior to, during or after settlement, including differential settlement and varying levels of mortality between habitat types following adaptation of t...

Infiltration capacity of bank filtration systems depends on water extraction and hydraulic resistance of the bed sediments. Lakebed hydraulics may be especially affected by clogging, which is dependent on settlement of fine particles, redox potential, and other factors. In the field, most of these processes are difficult to quantify, and thus, when calculating response to pumping the water flux...

Our expert system aims at the optimum and fast plan making for shield-tunneling works. It is an expert system of applied design problems that integrates such advanced technologies as relational databases , AI, and computer-aided design (CAD). This expert system is able to design and draw a suitable shield machine with an automatic output of design calculations and also specify an optimum contro...
