The simulation and early warning of cyanobacterial blooms in lakes are great significance. Controlling the growth cyanobacteria plateau is challenging due to unique geographical environment, climatic conditions, impact anthropogenic activities. Therefore, conducting simulations crucial effectively control lakes. This study aimed investigate Xingyun Lake, a representative lake China, using logistic model analyze patterns assess effects projects, along with influence meteorological...

Submerged vegetation changes the hydrodynamic characteristics of rivers, lakes, wetlands, and coastal zones. However, only a few studies have focused on effect flexible submerged under unidirectional flow. Therefore, laboratory experiments were conducted to study effects with different flexibility flow structure turbulence The results showed that reconfiguration coordination wave motion redistribute velocity, Reynolds stress, turbulent kinetic energy inside outside canopy. With gradual...

This paper develops new ontological and epistemological terrain to advance critical understanding of migrants' everyday lives in urban china. More specifically, we highlight the opportunities afforded by pluralist relational theoretical comparative empirical interrogation emotions across diverse work, domestic, family leisure times/spaces both within and, beyond cities. To that end, apply a counter-topographical approach kaleidoscope imaginative, implosive, mutual as competences resources...

Interdisciplinary research from China has generated a wealth of quantitative and qualitative insights into trans-, national, regional, local migration patterns over long short distances through attention to diverse topics, socio-economic groups, case-study locations. Our contribution in this paper is advance recent critical work that directing focus rural-to-urban "circular movements" toward more complex spatialities temporalities. To add value project, we not only engage with studies urban...

The wind drag coefficient, Cd, has a great influence on the numerical results obtained from shallow lakes. To analyze modeling impacts of Cd wind-driven currents, series simulations Lake Taihu were conducted at three grid resolutions (800 m × 800 m, 400 and 100 m) using empirical formulae Flather (F76), Large Pond (LP81), Yeager (LY04), Andreas (A12), Gao (G20). G20 formula produced optimum all for both water level velocity simulations; however, resolution was found to have significant...

Aquatic vegetation is one of the important parts shallow lake ecosystem, which has an impact on characteristics wind-driven wave and current. In this article, we embed module into flow model TELEMAC-3D TOMAWAC, respectively, construct coupling flow–wave–vegetation in open source Open TELEMAC-MASCARET. Through verification two sets experimental data, it been proven that can well reproduce influence current wave. Then, applied to simulation a typical lake, Taihu Lake. The results show...

<title>Abstract</title> Submerged aquatic vegetation (SAV) changes the turbulent structure of rivers, wetlands, estuaries, and lakes. However, few studies have focused on influence SAV hydrodynamic characteristics under wind-induced flow. Therefore, laboratory experiments were conducted to study effects flow turbulence spectral based decomposition method used separate wave velocity. Result shows that reduced local velocity within canopy elevates location zero-velocity point. The drag caused...

Knowledge of the extent water pollution along a diversion channel is essential for ensuring security and effectiveness projects. Thus, identifying trends in quality factors which influence diverted river prerequisite to safety diversion. As an important control unit Eastern Route South North Water Diversion Project, hilly eastern region Nansi Lake Basin (ENLB) suffers excess transferred into during flood season. The comprehensive index (CPI), Mann-Kendall trend test analysis variances were...

An electricity-carbon coupling market clearing model was established in the paper, where deviation cost of wind power output is introduced into objective function formulation to evaluate uncertainty power. Carbon-related costs and constraints are considered together balance electricity economy decarbonization. Based on this model, locational marginal prices (EC-LMP) containing component were derived by Lagrange multiplier. Examples utilized analyze impact EC-LMP quantitatively.

Firm generation capacity (FGC) is a vital metric to assess the stability of power for renewable energy like wind, solar, and hydropower. Considering uncertainty resources, first-order seasonal model based on Copula function employed stochastically simulate output solar power, natural inflow An FGC calculation wind-solar-hydro complementary system with hybrid pumped storage stations (HPSS) constructed subsequently. Case studies indicate that units effectively enables regulation through...

The rapid development of wind and solar power, with their randomness uncertainty, reduces system stability. Optimizing schedules complementary systems can help promote the accommodation power. However, it is challenging to formulate appropriate for multi-energy under uncertainty In this paper, an intelligent scheduling method based on deep reinforcement learning wind-solar-hydro-battery proposed. Firstly, A mathematical model problem established. Then, formulated as a Markov decision process...
