If abrupt climate change has occurred in the past and may be more likely under human forcing, it is relevant to look at adaptability of current infrastructure systems severe conditions recent past. Geologic evidence suggests two extreme droughts California during last few thousand years, each 120–200 years long, with mean annual streamflows 40%–60% historical mean. This study synthesized a 72 year drought half inflows using random sampling dry years. One synthetic hydrological record used,...
Abstract Hydrologic alteration due to hydropeaking reservoir operations is a main concern worldwide. Subdaily environmental flow constraints (ECs) on can be promising alternatives for mitigating negative impacts. However, those reduce the flexibility of hydropower plants, potentially with higher costs power system. To study economic and efficiency ECs, this work proposes novel framework comprising four steps: (i) assessment current subdaily hydrologic alteration; (ii) formulation...
The hydrodynamics of many hydropower reservoirs are controlled by the operation their power plant, but associated water quality impact is often poorly understood. In particular, significant hydropeaking operations plants affect not only downstream ecosystem also reservoir temperature. This paper contributes to understanding that link. For this, we coupled a hydrodynamic model (Estuary, Lake and Coastal Ocean Model, ELCOM) grid-wide system scheduling model. case study (Rapel, Chile), observe...
The design of water and energy systems has traditionally been done independently or considering simplified interdependencies between the two systems. This potentially misses valuable synergies them does not consider in detail distribution benefits different sectors regions. paper presents a framework to couple integrated water-power network simulators with multi-objective optimisation under uncertainty explore implications explicitly including spatial topology multi-sector A synthetic case...
Abstract Water management usually considers economic and ecological objectives, involves tradeoffs, conflicts, compromise, cooperation among objectives. Pareto optimality often is championed in water management, but its relationships with the mathematical representation of implications tradeoffs for optimal decisions, are rarely examined. We evaluate properties optimized to identify promising regions suggest strategies reducing better understand whether decision‐makers more or less likely...
Abstract This study investigates how environmental flows (e‐flows) can be designed as dynamic operating policies to optimize long‐term economic and ecosystem performance in reservoir systems. The main goal is provide e‐flow solutions that contribute better preparedness flexibility of hydro‐systems face multiyear stress periods, reducing the impact water crises. methodology framework combines a fish‐flow model with multi‐objective evolutionary algorithm construct multiple demand curves...
The Lancang-Mekong River (LMR) in Southeast Asia. LMR provides unparalleled economic and ecological resources for six Asian countries. However, the intensified impact of human activities, coupled with effects climate change, has led to alterations its natural flow, thereby disrupting river's flow regime. Ensuring future sustainable management downstream integrity this transboundary river requires understanding regional contributions altered at sub-basin level. We conducted an analysis last...
Representing peak and off-peak energy prices is often difficult in hydropower modeling because the time scale of price variability (hours or less) much shorter than that needed for many operations planning models (days to months). This work extends examines reliability an existing approximate method incorporate hourly information into revenue functions used reservoir optimization with larger steps (weekly monthly). The assumes constant head, exogenously known frequency distribution during...
We examine the effect of performance monitoring in public procurement through lens organizational culture a principal-agent model where manager (principal) and buyers (agents) may have different beliefs about how much government values efficiency. show that information not only increases efficiency but is greater when buyer's belief stronger than manager's belief. leverage new e-procurement system Chile to test these ideas by randomizing monthly reports on purchasing further whether...
Rivers provide multiple water uses and services, including offstream that are valued economically instream uses, such as recreation ecosystem preservation, rarely economically. In many countries, rights allocate to dedicated minimum flows the main instrument for allocation. However, do not ensure continuous reaches or aquatic habitats. An efficient allocation of requires quantifying benefits obtained from those so trade-offs between can be weighed against each other properly considered. This...
Irrigated agriculture is indispensable to the Lower Mekong River Basin (LMB), which ensures food security and provides livelihoods for tens of millions people. Irrigation, agricultural production, hydropower aquatic ecosystem health are intertwined in LMB, so it necessary adopt a holistic approach analyze irrigation problems. Here, we discuss challenges opportunities LMB irrigation. Bibliometric analysis carried out determine characteristics patterns watershed literature, such as importance...
Reservoir operation decisions often require balancing among objective bundles including hydropower generation, water supply reliability, recreation, environmental flows and flood control. This research employs a hydro-economic model to assess economically optimal of multi-purpose reservoir in Chile for irrigated agriculture. Conflicts exist inherently between agricultural requirements due demand seasonality mismatch. These conflicts are exacerbated as availability during dry years occurs...
Given its potentialities and characteristics, energy generation, food production, water availability have a strong interdependency correlation. Water is needed to produce food, while required food. This nexus brings several challenges when scarce resources must be allocated among competing uses, often in the form of unexpected tradeoffs. Addressing those requires knowledge about water–food–energy associated tradeoffs support allocation management decisions. Those are still not properly...
Despite its theoretical relationship, the effect of body size on performance species distribution models (SDM) has only been assessed in a few studies, and to date, evidence shows unclear results. In this context, Chilean fishes provide an ideal case evaluate relationship due their short (fishes between 5 cm 40 cm) conservation status, providing for at lower end worldwide fish representing relevant management tool conservation. We SDM nine river fishes, considering number records, metrics,...
The geological record contains extreme droughts beyond those seen in historical hydrologic records. For California, the several last few thousand years. Two of these are 120–200 years long, with mean annual streamflows between 40% and 60% mean. This study synthesized a 72-year for drought this character, having flow record. time series was used as input to an economic-engineering optimization model California's water supply system (CALVIN). allows exploration how management might respond...
Fostering environmental conflict resolutions in water management involves tradeoffs, conflicts, and compromise among economic objectives. Pareto optimality is often advocated for management, but its relationship with the nature mathematical representation of benefits, implications tradeoffs optimal decisions are rarely examined. We evaluate shape frontiers, their origins representing incentives parties to cooperate or over allocations. The same physical, ecological, relationships that...
