Abstract Intermittent rivers and ephemeral streams (IRES) account for over 50% of the world's river network are expected to increase with climate change increasing pressure on water resources. One significant challenge better manage IRES is unraveling threshold behavior streamflow generation, by understanding what controls triggers streamflow. This study aimed understand influence groundwater depth, soil hydraulic properties, rainfall generation in IRES, through analyzing spatiotemporal...
Mangrove forests provide essential ecosystem services, but are threatened by habitat loss, effects of climatic change and chemical pollutants. Hypersalinity can also lead to mangrove mortality, although mangroves adapted saline habitats. A recent dieback event >9 ha temperate ( Avicennia marina ) in South Australia allowed evaluate the generality anthropogenic impacts on ecosystems. We carried out multidisciplinary investigations, combining airborne remote sensing with on-ground...
Abstract. Streamflow dynamics for non-perennial networks remain poorly understood. The highly nonlinear unsaturated associated with the transitions between wetting and drying in systems make modelling cumbersome. This has stifled previous attempts alludes to why there is still a knowledge gap. In this study, we first construct conceptual model of physical processes streamflow generation an intermittent river system South Australia, based on hypothesis that vertical longitudinal soil...
Abstract In arid basins, infiltration through streambeds is considered the primary contributor to groundwater recharge; however, estimating streambed recharge at catchment scale remains a challenge. Moreover, spatial understanding of crucial for where and how much aquifer occurs could be enhanced. This study explored use continuously sampling shallow geophysical measurements over many kilometers dry in an intermittent stream basin. total, approximately 30 km was traversed, capturing...
Better understanding of surface water (SW) and groundwater (GW) interactions balances has become indispensable for management decisions. This study sought to characterize SW-GW in three crop fields located different irrigated valleys northern New Mexico by (1) estimating deep percolation (DP) below the root zone flood-irrigated fields; (2) characterizing shallow aquifer response inputs from DP associated with irrigation. Detailed measurements irrigation application, soil content...
Developing the meshTwo major considerations governed 2D model discretization; 1) stream network extent represented in mesh; and 2) mesh refinement along network.A representative was needed to be able capture development of active areas leading streamflow generation different parts catchment, while smaller elements streams were better topographic features allowing a more accurate representation hydrodynamic processes.Several meshes tested for suitability (Figure SI1).Initially, we created...
Abstract. Understanding streamflow dynamics at the catchment scale remains an arduous task; this is especially true for non-perennial networks. While modelling tools offer important advantages to study dynamics, highly nonlinear, unsaturated associated with transitions between wetting and drying in systems make cumbersome. This has stifled previous attempts alludes why there still a knowledge gap. In study, we first construct conceptual model of physical processes generation intermittent...
