Technical Due Diligence Report – Anderson Dam & Hydropower Plant (California, USA)

Alessandro Calvi — Sat, 22 Nov 2025 19:50:23 +0100

This study represents the technical due diligence of the hydroelectric plant consisting of the
Anderson Dam (Leroy Anderson) and its power station, located in California, USA.
This technical contribution is structured analyzing the hydrogeological aspects of the dam site's
geographical context, including its structural behavior in the event of significant seismic events, and
then going more in detail on the energy assessments that take into account the temporal distribution
of rainfall and flow rates, as well as the efficiency of the hydraulic machinery installed.

Statistical and Probabilistic Parameters Used as Reference for Hydrological-Energy Studies

Hydropower plant future production estimation is based on hydrological-hydraulic data. The present metholodogy validates the median as the reference parameter to be used for a better interpretation of statistical series, because it is a centered value where duration curves and their complementary curves intersect. Then, it is not affected by extreme events, providing a well representation of the whole dataset.

Geomechanical Challenges and Engineering Solutions for Tunnel Stability in the Himalayas: A Case Study Approach

Alessandro Calvi — Sun, 09 Feb 2025 22:30:03 +0100

The Himalayan region, characterized by complex geological formations and high tectonic activity, presents significant challenges for tunnel construction. This paper examines geomechanical issues such as tunnel squeezing, stress-induced instability, and rock bursting, with a focus on hydropower and railway tunnel projects in Nepal and India. Case studies, including the Chameliya Hydroelectric Project, Parbati II Hydroelectric Project, Nilgirikhola Hydroelectric Project, and railway tunnels in the Garhwal Himalaya, highlight the impact of weak, schistose rock masses and extreme overburden pressures. Various engineering methodologies, including empirical, semianalytical, analytical, and numerical modeling approaches, are discussed to assess stress states and deformation behavior. The study underscores the need for adaptive excavation techniques, such as the New Austrian Tunneling Method (NATM) and rock mass classification systems, to ensure tunnel stability. By integrating probabilistic analysis and advanced support systems, this research contributes to optimizing underground construction strategies in geologically challenging terrains.

ROBUSTNESS AND CONSEQUENCE BASED ASSESSMENT OF AN EXISTING DAM

Alessandro Calvi — Tue, 16 Apr 2024 10:34:02 +0200

Robustness plays a relevant role in the capacity of a structure to sustain abnormal loads
or to deal with unexpected events with large effects, such as explosions and terroristic
attacks. Such situations on dams may have extremely large consequences. For buildings,
the design approach that best implements robustness concepts is represented by the so
called “Consequence Based Design”: even if nothing is known about the cause, selective
element removals and extreme load on the structure are modeled, and their effects are
determined with respect to progressive collapse and damage arrest.
In the paper we try to set-up a “Consequence Based Assessment” of a typical example of
a gravity dam built between the ‘30s and ‘40s of the last century in the northwestern
Italian Alps. A simplified model of the structure is adopted. Removal of parts of the dam
cross-section is assumed to occur: the effects of the extent of damage is discussed on the
bases of the tension generated within the body of the dam.
