Abstract Non‐perennial streams have a global prevalence, but quantitative knowledge of the temporal dynamics their flowing length—namely extent wet portion stream network—remains limited, as monitoring spatiotemporal configuration channels is challenging in most settings. This work combines high spatial resolution visual surveys and camera‐based approaches to reconstruct space‐time network 3.7 km 2 Mediterranean catchment central Italy. Information on hydrological status derived from 40...

The monitoring of small headwater catchment represents a major issue in hydrology, especially remote areas, where gathering real-time hydrological data is often prohibitive due to the limited availability power and connectivity. However, recent advances non-contact computer vision informatic technology offer an opportunity fill such technical gap. In this regard, we designed developed MagicHydroBox prototype (MHB), all-in-one camera processing unit system aimed at water level rivers. tasks...

The study of non-perennial streams requires extensive experimental data on the temporal evolution surface flow presence across different nodes channel networks. However, consistency and homogeneity available datasets is threatened by empirical burden required to map stream network expansions contractions. Here, we developed a data-driven, graph-theory framework aimed at representing hierarchical structuring dynamics (i.e., order node activation/deactivation during expansion/retraction)...

Introduction Monitoring water levels of ephemeral streams is a difficult yet important task in hydrology, especially when studying minor river flows remote areas. The installation flow gauging stations on upstream tributaries impacted by the lack economic resources, accessibility problems and unstable morphological conditions riverbeds avoiding implementation distributed observation networks at large scales. This major challenge hydrology may be addressed eventually adopting image-analysis...

Recently, increased attention has been devoted to intermittent and ephemeral streams (IRES) due the recognition of their importance for ecology, hydrology, biogeochemistry. However, IRES dynamics still demand further research, traditional monitoring approaches present several limitations in continuously accurately capturing river network expansion/contraction. Optical-based have shown promise noninvasively estimating water level streams: a simple setup made up wildlife camera reference white...

Abstract. Monitoring ephemeral and intermittent streams is a major challenge in hydrology. While direct field observations are best to detect spatial patterns of flow persistence, on site inspections time labor intensive may be impractical difficult-to-access environments. Motivated by latest advancements digital cameras computer vision techniques, this work, we describe the development application stage-camera system monitor water level ungauged headwater streams.

Non-perennial streams are those that periodically cease to flow in at least one point along their network. The research community well recognizes the importance of such watercourses for they have a global prevalence and provide diverse hydrological functions ecosystem services. spatiotemporal pattern active drainage network is anything but simple, sometimes showing very complex pattern. streams, fact, often located heterogeneous environments, which combination climate, morphology, land...

<p>While the interest in ephemeral and intermittent streams increased last few decades, monitoring such watercourses remains a major challenge hydrology. Direct field observations are best to detect spatial patterns of flow persistence, but they time labour intensive may be impractical difficult-to-access environments. Moreover, instrumentation deployed riverbed can provide information about presence/absence water, nevertheless these methods lack streamflow quantification....
