Developing a universal tunnel span classification from global tunnel databases

Deep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

Environmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

Environmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

A missing data processing method for dam deformation monitoring data using spatiotemporal clustering and support vector machine model

Water Science and Engineering
Deformation monitoring is a critical measure for intuitively reflecting the operational behavior of a dam. However, the deformation monitoring data are often incomplete due to environmental changes, monitoring instrument faults, and human operational ...

Environmental Statecraft, Fragmented Authoritarianism, and Technocratic Governance: The Structure and Agency of China's Local Environmental Politics

Environmental Policy and Governance, EarlyView.
ABSTRACT Local environmental politics in China is often said to be dominated by state‐controlled modes of multi‐level governance. However, top‐down governance is embedded within and transformed by local politics, adding complexity to governance practices and environmental outcomes.

Next‐Generation Seismic Performance Assessment Through Multi‐Component Ground Motion Compatible Intensifying Artificial Acceleration

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite the crucial need for fully quantitative risk assessment of large‐scale structures, their performance is typically assessed through deterministic or semi‐quantitative approaches. The main preventing factor is the computational burden of probabilistic seismic analyses.

Modeling the Nexus Between Climate Risk, Energy Consumption, and Financial Market Performance in Emerging Countries

International Studies of Economics, EarlyView.
Abstract This paper examines the link between climate risk, energy consumption, and financial market performance in a sample of emerging countries over the period 2000–2024. The objective is to model the dynamic interactions between these three dimensions, in order to understand the extent to which energy dependence and exposure to climate risks ...

Horizontal and Vertical Movement of Concrete Dam Erecting on Sandy Soil under Seismic Loading

Diyala Journal of Engineering Sciences
Concrete dams are the strongest dams, designed for flood control, electricity generation, and water management. They can become unstable due to ground shaking and earthquake impacts, resulting in stability loss due to embankment and foundation materials
