TLDR
In this article, a review of existing knowledge on nutrient and organic matter dynamics in IRES considering in-stream processes, interactions with subsurface and lateral compartments, and linkages between terrestrial ecosystems and IRES networks at the catchment scale are discussed.Abstract:
The hydrological regimes of most intermittent rivers and ephemeral streams (IRES) include the alternation of wet and dry phases in the stream channel and highly dynamic lateral, vertical, and longitudinal connections with their adjacent ecosystems. Consequently, IRES show a unique ‘biogeochemical heartbeat’ with pulsed temporal and spatial variation in nutrient and organic matter inputs, in-stream processing, and downstream transport. Given that IRES are widespread, their improper consideration may cause inaccurate estimation of nutrient and carbon fluxes in river networks. Here, we review existing knowledge on nutrient and organic matter dynamics in IRES considering in-stream processes, interactions with subsurface and lateral compartments, and linkages between terrestrial ecosystems and IRES networks at the catchment scale. Moreover, knowledge gaps and research needs are discussed. Our purpose is to contribute to the flourishing knowledge and research on the biogeochemistry of IRES by providing a comprehensive view of nutrient and organic matter dynamics in these ecosystems.read more

TL;DR: It is found that sediments, due to their large quantities within riverbeds, contribute most to the overall flux of dissolved substances during rewetting events, and that flux rates distinctly differ among climate zones.

Quantifying spatiotemporal variation in headwater stream length using flow intermittency sensors
TL;DR: Stream length hysteresis was evident for larger storms with higher event and antecedent precipitation that resulted in peak runoff > 15 mm/day, and a correlation analysis between flow duration at the sensor locations and common topographic metrics used in stream network modeling did not fully explain spatial variation in flow duration.

TL;DR: It is demonstrated that progressive drying drives considerable changes in in-stream N cycling and the associated nitrifying microbial communities, and that sporadic rainfall can modulate these effects.
