Long‐term hydrologic recovery after wildfire and post‐fire forest management in the interior Pacific Northwest

Abstract Elevated wildfire activity in many regions recent decades has increased concerns about the short‐ and long‐term effects on water quantity, quality, aquatic ecosystem health. Often, loss of canopy interception transpiration, along with changes soil structural properties, leads to elevated total annual yields, peak flows, low flows. Post‐fire land management treatments are often used promote forest regeneration mitigate terrestrial ecosystems. However, few studies have investigated longer‐term either or post‐fire catchment hydrology. Our objectives were quantify compare both discharge, evapotranspiration (AET).

Achieving global food security in the face of climate change is a critical challenge, particularly vulnerable countries like Indonesia. To effectively address this systems-based approach utilizing climate-hydrological-crop models has emerged as an integral approach. These integrate climate, hydrological, and crop components to understand predict complex interactions within agricultural systems their responses variables. By employing approach, policymakers, researchers, stakeholders can gain comprehensive insights into potential consequences on growth, water availability, soil fertility, overall yield. However, challenges exist implementation including data reliability; scarcity complete long-term data; lack experimental information about species, especially local varieties; inadequate research resources; expertise concerning modeling approaches; testing; inaccurate calibration; model uncertainties. Furthermore, limitations implementing improving availability reliability data, collection method, quality should be conducted ensure accuracy simulation prediction. Finally, models, alongside improved modelling techniques, serve essential tools for guiding development effective adaptation measures mitigate impacts rice production

Leveraging a time-series event separation method to disentangle time-varying hydrologic controls on streamflow – application to wildfire-affected catchments

Hydrology and earth system sciences, Journal Year: 2025, Volume and Issue: 29(1), P. 27 - 43

Published: Jan. 3, 2025

Abstract. Increasing watershed disturbance regimes, such as from wildfire, are a growing concern for natural resource managers. However, the influence of disturbances on event-scale rainfall–runoff patterns has proved challenging to disentangle other hydrologic controls. To better isolate effects, this study evaluates several time-varying controls patterns, including water year type, seasonality, and antecedent precipitation. accomplish this, we developed Rainfall–Runoff Event Detection Identification (RREDI) toolkit, an automated time-series event separation attribution algorithm that overcomes limitations existing techniques. The RREDI toolkit was used generate dataset 5042 events nine western US watersheds. By analyzing large dataset, type season were identified significant whereas moisture pinpointed limited control. Specific effects wildfire runoff response then demonstrated two burned watersheds by first grouping based controls, wet versus dry types. role should be considered in future analysis increasing changing wildfires streamflow. could readily applied investigate patterns.

Vegetation fires are amongst most hydrologically landscape disturbances (Ebel & Mirus, 2014) affect ~4% of vegetated land surface annually (Giglio, Randerson, van der Werf, 2013).

We implemented a field experiment to examine the effects of manipulations temperature and water on ponderosa pine (Pinus Douglas ex P. Lawson & C. Lawson) Douglas-fir (Pseudotsuga menziesii (Mirb.)

Average was highest Wt plots, followed Co, WmWt, Wm respectively. This general trend observed for both conifer species, although average generally higher than Douglas-fir. Our findings suggest warming temperatures associated drought are likely low-elevation forests Range future composition structure differ notably from historic patterns some areas. relevant other forested ecosystems which climate similarly dominant species.
