Cellular-automata-based ecological and ecohydraulics modelling

Abstract

Spatially lumped models may fail to take into account the effects of spatial heterogeneity and local interactions. These properties sometimes are crucial to the dynamics and evolutions of ecosystems. This paper started from the fundamental aspects of CA and focused on the development and application of the approach to ecological and ecohydraulics modelling.Application cases include modelling of prey-predator dynamics by stochastic CA and simulation of riparian vegetation successions in a regulated river by rule-based CA. The results indicated that spatially explicit paradigms such as cellular automata (CA) have a strong capability to bridge the local processes and global patterns.

A general overview of formal languages for individual-based modelling of ecosystems

“…There are several tools for the simulation of cellular automata. Chen et al developed a rule-based stochastic cellular automata model to simulate the classical predator-prey Lotka-Volterra model [26].…”

An Adaptive Relaxed Cellular Automata Method for Reliability-Based Hydropower Operation of Reservoirs

“…CA has been used to model di erent problems such as pollutants dispersion in the atmosphere [31], heat ow [32], absorptiondesorption phenomenon [33], inter-di usion of atoms of two materials [34], the solidi cation process [35], and drug therapies for HIV infection [36]. Chen et al [37] focused on the development and application of CA approach for ecological and ecohydraulics modeling. Li et al [38] developed an integrated model, which combined a two-dimensional hydrodynamic module with a vegetation evolution module and a sh habitat module.…”

Individual-based modelling of fish population dynamics in the river downstream under flow regulation

“…The conventional population models are mainly aggregated and conceptually based. Such models often oversimplify or even neglect the individual differences and local interactions (Kitazawa et al, 2008;Chen et al, 2009a). The fish habitat models describe the suitability of the aquatic environment for the specific species (Bovee, 1982), thus they can be applied to analyze and assess the ecological effects of river developments and restorations (Shuler and Nehring, 1993;Shields et al, 1997;Duel et al, 2002).…”
