This paper investigates the kinematic flow and precipitation evolution of a winter storm over and upstream of the Wasatch Mountains (IPEX IOP3) using a multiply nested version of the Pennsylvania State University-National Center for Atmospheric Research (NCAR) Mesoscale Model (MM5). Validation using in-situ aircraft data, radiosondes, ground-based radar, and surface observations showed that the...

This study numerically predicts the failure scenario of a cracked concrete gravity dam through a push-over nonlinear analysis. The mixed-mode Linear Elastic Fracture Mechanics (LEFM) was employed using the extended finite element method (XFEM). The dam base was considered to be fully fixed without any foundation effects. The hydrostatic pressure on the dam's upstream face was increased incremen...

The Jinsha River, upstream of the Yangtze flows through southeastern margin plateau, providing an opportunity to study plateau uplift relative Sichuan basin fluvial geomorphology. Eight tributaries River located at transition boundary from were analyzed for feature longitudinal profile and its evolution. spatial distribution slope-break knickpoints in catchment was determined by slope-area anal...

Abstract The contributions of the current analytical models on prediction stability slope subjected to slide head toppling failure mechanisms, have always focused idealized geometry comprising regular blocks dipping into face. Besides, influence groundwater and stabilizations from lowermost block been overlooked in available literature. In this article, solutions that incorporates kinematic mec...

This paper presents a new and easily repeatable method for assessing the susceptibility of glacial lakes to outburst floods (GLOFs) within the Peruvian region of the Cordillera Blanca. The presented method was designed to: (a) be repeatable (from the point of view of the demands on input data), (b) be reproducible (to provide an instructive guide for different assessors), (c) provide multiple r...

An automated algorithm based on the dynamic hydrological and hydraulic simulation modules in Storm Water Management Model (SWMM) was developed to aid the design of storm sewer networks, provided that a layout is given. Numerical performance of the proposed algorithm was compared with the existing design methods with two application cases. The automated computation process of the sewer network d...

A two-dimensional, hydrostatic, nearly adiabatic primitive equation model is used to study the evolution of a front passing across topography. Frontogenesis is forced by shearing deformation associated with the nonlinear evolution of an Eady wave. This study extends previous work by including an upper-level potential vorticity (PV) anomaly and a growing baroclinic wave in a baroclinically unsta...
