Sensitivity analysis of factors affecting gravity dam anti-sliding stability along a foundation surface using Sobol method

open access: yesWater Science and Engineering, 2023
The anti-sliding stability of a gravity dam along its foundation surface is a key problem in the design of gravity dams. In this study, a sensitivity analysis framework was proposed for investigating the factors affecting gravity dam anti-sliding ...

EVICT, NEGLECT, OR INVEST? Community Power and the Politics of Urban Informality Governance in Jakarta

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Why do some informal neighborhoods receive public investment while others are neglected or evicted? This article addresses the inconsistent governmental responses to informal settlements in Jakarta, Indonesia, during the democratic period. State actions range from violent evictions to tolerance and community‐led improvements.

Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis

open access: yesComputer Graphics Forum, EarlyView.
In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40

Between Dispossession and Inclusion: Land Injustice and Project‐Based Citizenship in the Bagré Irrigation Scheme (Burkina Faso)

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Large‐scale irrigation schemes are central to agrarian transformation in sub‐Saharan Africa, yet their political implications are often reduced to questions of land redistribution or agrarian differentiation. Although existing scholarship has documented how irrigation restructures agrarian relations and generates dispossession, less attention ...

Type Selection between Arch Dam and Gravity Dam Based on Construction Simulation: A Case Study

open access: yes, 2023
The issue of dam type selection is a prevalent challenge in water resource allocation engineering. The site of the Y2 dam in China is suitable for building concrete arch dams and roller-compacted concrete (RCC) gravity dams.

Factors influencing hysteresis characteristics of concrete dam deformation

open access: yesWater Science and Engineering, 2017
Thermal deformation of a concrete dam changes periodically, and its variation lags behind the air temperature variation. The lag, known as the hysteresis time, is generally attributed to the low velocity of heat conduction in concrete, but this ...
