KINEROS (KINematic runoff and EROSion) originated in the 1960s as a distributed event-based model that conceptualizes watershed cascade of overland flow elements into trapezoidal channel elements. was one first widely available models interactively coupled finite difference approximation kinematic equations to physically based infiltration model. Development improvement continued from on variety projects for range purposes, which has resulted suite KINEROS-based modeling tools. This article...
Abstract Ephemeral and intermittent streams are abundant in the arid semiarid landscapes of Western Southwestern United States (U.S.). Connectivity ephemeral to relatively few perennial reaches through runoff is a major driver ecohydrology region. These supply water, sediment, nutrients, biota downstream rivers. In addition, they provide recharge alluvial regional groundwater aquifers that support baseflow mainstem stream over extended periods when little or no precipitation occurs. Episodic...
Abstract Appropriate land‐use, watershed‐management, and flood‐attenuation plans are critical in the cross‐border urban environment known collectively as Ambos Nogales. This paper summarizes methodologies for predicting watershed response associated with land‐use change within a spatial temporal context through use of hydrological model setting. The KINEROS2 is implemented via Automated Geospatial Watershed Assessment 2.0 geographic information system interface to evaluate Nogales, Arizona,...
This study is a coordinated effort by the U.S. Geological Survey (USGS), Department of Agriculture, Agricultural Research Service (USDA ARS), and Arizona State University, with assistance from Army Corps Engineers, University Wyoming, Arizona. The specific objectives were: to determine water needs riparian vegetation through growing season throughout SPRNCA ensure its long-term ecological integrity; quantify total use within SPRNCA; source used key plant species SPRNCA. To meet these...
Spatial and temporal rainfall variability over watersheds directly impacts the hydrologic response virtually all watershed scales. Changes in precipitation regime decades due to some combination of inherent local climate change may contribute changes vegetation, water supply, and, longer timescales, landscape evolution. Daily, seasonal, annual volumes intensities from dense network rain gauges on Agricultural Research Service, U. S. Department Agriculture Walnut Gulch Experimental Watershed...
Rapid post-fire watershed assessment to identify potential trouble spots for erosion and flooding can potentially aid land managers Burned Area Emergency Rehabilitation (BAER) teams in deploying mitigation rehabilitation resources. These decisions are inherently complex spatial nature require a distributed hydrological modeling approach. The extensive data requirements the task of building input parameter files have presented obstacles timely effective use rainfall-runoff models by BAER...

Flooding in Ambos Nogales often exceeds the capacity of channel and adjacent land areas, endangering many people. The Wash is being studied to prevent future flood disasters detention features are installed tributaries wash. This paper describes application KINEROS2 model efforts understand these under various urbanization scenarios. Results depict a reduction peak flow for 10-year, 1-hour event based on current use with features. However, results also demonstrate that larger storm events...
The Automated Geospatial Watershed Assessment Tool (AGWA) and the Rangeland Hydrology Erosion Model (RHEM) were used to evaluate conservation practices on Cienega Creek watershed (CCW) that implemented under Conservation Effects Project (CEAP) Grazing Lands. CEAP Lands is a multi-agency effort quantify environmental effects of programs, develop science base for managing rangelands quality using (Spaeth et al. 2013). evaluation was performed CCW Empire Ranch, located in southeastern Arizona,...
KINEROS originated in the 1970's as a distributed event-based rainfall-runoff erosion model. A unique feature at that time was its interactive coupling of finite difference approximation kinematic overland flow equations to Smith-Parlange infiltration Development and improvement has continued for variety projects purposes. As result, suite KINEROS2-based modeling tools been developed can be executed from single shell. The range KINEROS2 flash-flood forecasting tool continuous KINEROS2-Opus2...

The Walnut Gulch Experimental Watershed is a semi-arid experimental watershed and long-term agro-ecosystem research (LTAR) site managed by the USDA-Agricultural Research Services (ARS) Southwest Center for which high-resolution, hydroclimatic data are available across its 149-km2 drainage area. Quality control quality assurance of massive set major challenge. We present analysis 50 years sets to develop strategy identify errors inconsistencies in historical rainfall runoff databases. A...
