Dynamical stability of water distribution networks

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019
Water distribution networks are hydraulic infrastructures that aim to meet water demands at their various nodes. Water flows through pipes in the network create nonlinear dynamics on networks. A desirable feature of water distribution networks is high resistance to failures and other shocks to the system.

Reliability based rehabilitation of water distribution networks by means of Bayesian networks

Journal of Water and Land Development, 2017
Water plays an essential role in the everyday lives of the people. To supply subscribers with good quality of water and to ensure continuity of service, the operators use water distribution networks (WDN). The main elements of water distribution network (

Scaling-Laws of Flow Entropy with Topological Metrics of Water Distribution Networks

Entropy, 2018
Robustness of water distribution networks is related to their connectivity and topological structure, which also affect their reliability. Flow entropy, based on Shannon’s informational entropy, has been proposed as a measure of network redundancy and ...

Emergent behavior of soil fungal dynamics:influence of soil architecture and water distribution [PDF]

, 2012
Macroscopic measurements and observations in two-dimensional soil-thin sections indicate that fungal hyphae invade preferentially the larger, air-filled pores in soils. This suggests that the architecture of soils and the microscale distribution of water
